In Oracle HTTP Server distributed with Oracle9i Release 2 (9.2), the wdbsvr.app file contains information about the DAD to access Oracle Application Express. A DAD is a set of values that specify how the Oracle HTTP Server component modplsql connects to the database server to fulfill an HTTP request.
Topics in this appendix include:
Before installing Oracle Application Express, Oracle recommends that you complete the following steps:
Review and satisfy all Oracle Application Express installation requirements. See "Oracle Application Express Installation Requirements".
Shut down any existing Oracle Database instances as well as Oracle-related processes.
Shut down any existing Oracle Database instances with normal or immediate priority, except for the database where you plan to install the Oracle Application Express schemas. On Oracle Real Application Clusters (Oracle RAC) systems, shut down all instances on each node.
If Automatic Storage Management (ASM) is running, shut down all databases that use ASM except for the database where you will install Oracle Application Express, and then shut down the ASM instance.
You can use the Windows Services utility, located either in the Windows Control Panel or from the Administrative Tools menu (under Start and then Programs), to shut down Oracle Database and ASM instances. Names of Oracle databases are preceded with OracleService. The Oracle ASM service is named OracleASMService+ASM. In addition, shut down the OracleCSService service, which ASM uses. Right-click the name of the service and from the menu, choose Stop.
Back up the Oracle Database installation.
Oracle recommends that you create a backup of the current installation of Oracle Database installation before you install Oracle Application Express. You can use Oracle Database Recovery Manager, which is included the Oracle Database installation, to perform the backup.
Start the Oracle Database instance that contains the target database.
After backing up the system, you must start the Oracle instance that contains the target Oracle database. Do not start other processes such as the listener or Oracle HTTP Server. However, if you are performing a remote installation, make sure the database listener for the remote database has started.
This section describes how to install Oracle Application Express by downloading a ZIP file from OTN and then configuring Oracle HTTP Server distributed with Oracle9i Release 2.
Topics in this section include:
Oracle Application Express requires an Oracle database that is release 9.2.0.3 or later. To learn more, see the Oracle Database Installation Guide for your operating environment and "Recommended Pre-installation Tasks".
To install Oracle Application Express:
Download the file apex_3.2.zip from the Oracle Application Express download page. See:
http://www.oracle.com/technetwork/developer-tools/apex/overview/index.html
Note that the actual file name may differ if a more recent release has shipped since this document was published.
Unzip apex_3.2.zip as follows, preserving directory names:
UNIX and Linux: Unzip apex_3.2.zip
Windows: Double click the file apex_3.2.zip in Windows Explorer
Change your working directory to apex.
Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. For example:
On Windows:
SYSTEM_DRIVE:\ sqlplus /nolog SQL> CONNECT SYS as SYSDBA Enter password: SYS_password
On UNIX and Linux:
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
Disable any existing password complexity rules for the default profile. See "Configuring Password Protection" in Oracle Database Security Guide.
Select the appropriate installation option.
Full development environment provides complete access to the Application Builder environment to develop applications. A Runtime environment enables users to run applications that cannot be modified. To learn more, see "About the Oracle Application Express Runtime Environment".
Available installation options include:
Full development environment. Run apexins.sql passing the following four arguments in the order shown:
@apexins tablespace_apex tablespace_files tablespace_temp images
Where:
tablespace_apex is the name of the tablespace for the Oracle Application Express application user.
tablespace_files is the name of the tablespace for the Oracle Application Express files user.
tablespace_temp is the name of the temporary tablespace.
images is the virtual directory for Oracle Application Express images. To support future Oracle Application Express upgrades, define the virtual image directory as /i/.
Example:
@apexins SYSAUX SYSAUX TEMP /i/
Runtime environment. Run apxrtins.sql passing the following arguments in the order shown:
@apxrtins tablespace_apex tablespace_files tablespace_temp images
Where:
tablespace_apex is the name of the tablespace for the Oracle Application Express application user.
tablespace_files is the name of the tablespace for the Oracle Application Express files user.
tablespace_temp is the name of the temporary tablespace.
images is the virtual directory for Oracle Application Express images. To support future Oracle Application Express upgrades, define the virtual image directory as /i/.
Example:
@apxrtins SYSAUX SYSAUX TEMP /i/
When Oracle Application Express installs it creates three new database accounts:
APEX_030200 - The account that owns the Oracle Application Express schema and metadata.
FLOWS_FILES - The account that owns the Oracle Application Express uploaded files.
APEX_PUBLIC_USER - The minimally privileged account used for Oracle Application Express configuration with Oracle HTTP Server and mod_plsql.
If you are upgrading from a previous release, FLOWS_FILES, already exists and APEX_PUBLIC_USER is created if it does not already exist.
|
Tip: Oracle Application Express must be installed from a writable directory on the file system. See "Reviewing a Log of an Installation Session". |
In a new installation of Oracle Application Express, or if you are converting a runtime environment to a development environment, you must change the password of the internal ADMIN account. In an upgrade scenario, the password will be preserved and carried over from the prior release.
To change the password for the ADMIN account:
Change your working directory to the apex directory where you unzipped the installation software.
Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. For example:
On Windows:
SYSTEM_DRIVE:\ sqlplus /nolog SQL> CONNECT SYS as SYSDBA Enter password: SYS_password
On UNIX and Linux:
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
Run apxchpwd.sql. For example:
@apxchpwd
When prompted enter a password for the ADMIN account.
After you install Oracle Application Express, you must restart the processes that you stopped before you began the installation, such as listener and other processes. In addition, restart Oracle HTTP Server.
This section describes how to configure Oracle HTTP Server with mod_plsql distributed with Oracle9i Release 2.
Topics in this section include:
The APEX_PUBLIC_USER account is locked at the end of a new installation of Oracle Application Express. You must unlock this account before configuring the database access descriptor (DAD) in a new installation.
To unlock the APEX_PUBLIC_USER account:
Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. For example:
On Windows:
SYSTEM_DRIVE:\ sqlplus /nolog SQL> CONNECT SYS as SYSDBA Enter password: SYS_password
On UNIX and Linux:
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
Run the following statement:
ALTER USER APEX_PUBLIC_USER ACCOUNT UNLOCK
The APEX_PUBLIC_USER account is created with a random password in a new installation of Oracle Application Express. You will must change the password for this account before configuring the database access descriptor (DAD) in a new installation.
To change the password for the APEX_PUBLIC_USER account:
Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. For example:
On Windows:
SYSTEM_DRIVE:\ sqlplus /nolog SQL> CONNECT SYS as SYSDBA Enter password: SYS_password
On UNIX and Linux:
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
Run the following statement:
ALTER USER APEX_PUBLIC_USER IDENTIFIED BY new_password
Where new_password is the new password you are setting for APEX_PUBLIC_USER. You will use this password when creating the DAD in the sections that follow.
In the default profile in Oracle Database 11g, the parameter PASSWORD_LIFE_TIME is set to 180. If you are using Oracle Database 11g with Oracle Application Express, this causes the password for APEX_PUBLIC_USER to expire in 180 days. As a result, your Oracle Application Express instance will become unusable until you change the password.
To prevent this behavior, create another profile in which the PASSWORD_LIFE_TIME parameter is set to unlimited and alter the APEX_PUBLIC_USER account and assign it the new profile.
|
See Also: Oracle Database Security Guide for information on creating profiles and assigning them to database users. |
Whether you are loading a new installation or upgrading from a previous release, you must copy the images directory from the top level of the apex\images directory to the location on the file system containing the Oracle home for Oracle HTTP Server.
Topics in this section include:
During an upgrade, you must overwrite your existing images directory. Before you begin the upgrade, to ensure that you can revert to the previous version, Oracle recommends that you create a copy of your existing images directory for Oracle Application Express, indicating the release number of the images (for example, images_3_1).
To locate the images directory on the file system, review the httpd.conf file for the text alias /i/.
When you locate the images directory path, copy the existing images directory to a backup location. Doing so enables you to revert to the previous release, if that becomes necessary.
After you copy the existing images directory, use the following command syntax to copy the apex\images directory from the Oracle Database home to the existing images directory path, overwriting the existing images:
On Windows:
xcopy /E /I APEX_HOME\apex\images ORACLE_HTTPSERVER_HOME\Apache\images
On UNIX and Linux:
cp -rf APEX_HOME/apex/images ORACLE_HTTPSERVER_HOME/Apache
In the preceding syntax examples:
ORACLE_HOME is the Oracle Database Oracle home
ORACLE_HTTPSERVER_HOME is the existing Oracle HTTP Server Oracle home
After installation, copy the directory apex/images.
On Windows:
xcopy /E /I ORACLE_HOME\apex\images ORACLE_HTTPSERVER_HOME\Apache\images
On UNIX and Linux:
cp -rf $ORACLE_HOME/apex/images ORACLE_HTTPSERVER_HOME/Apache
In the preceding syntax examples:
ORACLE_HOME is the Oracle Database Oracle home
ORACLE_HTTPSERVER_HOME is the existing Oracle HTTP Server Oracle home
To create the DAD, you modify the wdbsvr.app file and add an entry for Oracle Application Express.
To modify the wdbsvr.app file:
Use a text editor and open the wdbsvr.app file:
On Windows, see:
ORACLE_HTTPSERVER_HOME\Apache\modplsql\cfg\wdbsvr.app
On UNIX and Linux, see:
ORACLE_HTTPSERVER_HOME/Apache/modplsql/cfg/wdbsvr.app
Add an entry for Oracle Application Express using the following syntax. Only change the settings indicated in italics.
[DAD_apex] connect_string = localhost:1521:orcl password = apex username = apex_public_user default_page = apex document_table = wwv_flow_file_objects$ document_path = docs document_proc = wwv_flow_file_mgr.process_download reuse = Yes enablesso = No stateful = STATELESS_RESET nls_lang = American_America.AL32UTF8
Where:
connect_string refers to the host ID, port number, and Oracle9i database where Oracle Application Express was installed. Use the format host:port:sid.
If the Oracle9i version of Oracle HTTP Server you want to use is installed in the same Oracle home as the database you specified for use with Oracle Application Express, leave this parameter blank.
password is the password you changed for the APEX_PUBLIC_USER. See "Change the Password for the APEX_PUBLIC_USER Account".
nls_lang determines the language setting of the DAD. The character set portion of the nls_lang value must always be set to AL32UTF8, regardless of whether or not the database character set is AL32UTF8.
If either the territory portion or the language portion of the NLS settings contains a space, you must wrap the value in double quotes as shown in the following example:
nls_lang = "ENGLISH_UNITED KINGDOM.AL32UTF8"
You can find information about your database's NLS settings by querying the view NLS_DATABASE_PARAMETERS as shown in the following example:
SELECT parameter,value
FROM nls_database_parameters
WHERE PARAMETER IN ('NLS_CHARACTERSET','NLS_LANGUAGE','NLS_TERRITORY');
Leave the remaining settings, including the user name setting, as they appear in the previous example.
Save and exit the wdbsvr.app file.
You must modify the httpd.conf file to include an alias that points to the file system path where you copied the images directory. You may also need to modify the httpd.conf file to add two new MIME types to support SQL Workshop.
To modify httpd.conf file:
Use a text editor and open the httpd.conf file:
On Windows:
ORACLE_HTTPSERVER_HOME\Apache\Apache\conf\httpd.conf
On UNIX and Linux:
ORACLE_HTTPSERVER_HOME/Apache/Apache/conf/httpd.conf
Add an alias entry that points to the file system path where you copied the images directory.
Windows example:
Alias /i/ "C:\oracle\ora92\Apache\Apache\images/"
UNIX and Linux example:
Alias /i/ "/home/oracle/OraHome1/Apache/Apache/images/"
Note that the previous examples assume you specified the image directory alias as /i/ when you ran the apexins.sql script.
Note you must include the forward slash (/) at the end of the path.
Next, add the following two lines to support SQL Workshop if they do not currently exist:
AddType text/xml xbl AddType text/x-component htc
If you are upgrading from Oracle HTML DB 2.0 or later, these MIME types should already exist.
Save and exit the httpd.conf file.
Stop and restart Oracle HTTP Server.
On Windows, Stop and restart Oracle HTTP Server:
Stop Oracle HTTP Server - From the Start menu, select Programs, Oracle - OraHome, Oracle HTTP Server, and Stop HTTP Server.
Restart Oracle HTTP Server - From the Start menu, select Programs, Oracle - OraHome, Oracle HTTP Server, and Start HTTP Server.
On UNIX and Linux, execute the following commands:
ORACLE_HTTPSERVER_HOME/Apache/Apache/bin/apachectl stop ORACLE_HTTPSERVER_HO ME/Apache/Apache/bin/apachectl start
Note that if the Oracle HTTP Server is listening on a port less than 1024, then these commands must be executed as a privileged user (such as root).
By default, the ability to interact with network services is disabled in Oracle Database 11g release 1 (11.1). Therefore, if you are running Oracle Application Express with Oracle Database 11g release 1 (11.1), you must use the new DBMS_NETWORK_ACL_ADMIN package to grant connect privileges to any host for the APEX_030200 database user. Failing to grant these privileges results in issues with:
Sending outbound mail in Oracle Application Express.
Users can call methods from the APEX_MAIL package, but issues arise when sending outbound email.
Using Web services in Oracle Application Express.
PDF/report printing.
Searching for content in online Help (that is, using the Find link).
Topics in this section include:
|
Tip: To run the examples described in this section, the compatible initialization parameter of the database must be set to at least 11.1.0.0.0. By default an 11g database will already have the parameter set properly, but a database upgraded to 11g from a prior version may not. See "Creating and Configuring an Oracle Database" in Oracle Database Administrator's Guide for information about changing database initialization parameters. |
The following example demonstrates how to grant connect privileges to any host for the APEX_030200 database user. This example assumes you connected to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role.
DECLARE

If you receive an ORA-44416: Invalid ACL error after running the previous script, use the following query to identify the invalid ACL:
REM Show the dangling references to dropped users in the ACL that is assigned
REM to '*'.
SELECT ACL, PRINCIPAL

CNT NUMBER;
BEGIN
-- Look for the object ID of the ACL currently assigned to '*'
SELECT ACLID INTO ACL_ID FROM DBA_NETWORK_ACLS
WHERE HOST = '*' AND LOWER_PORT IS NULL AND UPPER_PORT IS NULL;

END LOOP;
ELSE
DELETE FROM XDB.XDB$ACL WHERE OBJECT_ID = ACL_ID;
END IF;
END;
/
REM commit the changes.
COMMIT;
Once the ACL has been fixed, you must run the first script in this section to apply the ACL to the APEX_030200 user. See "Granting Connect Privileges".
Oracle highly recommends you configure and use a Secure Sockets Layer (SSL) to ensure that passwords and other sensitive data are not transmitted in clear text in HTTP requests. Without the use of SSL, passwords could potentially be exposed, compromising security.
SSL is an industry standard protocol that uses RSA public key cryptography in conjunction with symmetric key cryptography to provide authentication, encryption, and data integrity.
The Oracle Application Express interface is translated into German, Spanish, French, Italian, Japanese, Korean, Brazilian Portuguese, Simplified Chinese, and Traditional Chinese. A single instance of Oracle Application Express can be installed with one or more of these translated versions. At runtime, each user's Web browser language settings determine the specific language version.
The translated version of Oracle Application Express should be loaded into a database that has a character set that supports the specific language. If you attempt to install a translated version of Oracle Application Express into a database that does not support the character encoding of the language, the installation may fail or the translated Oracle Application Express instance may appear corrupt when run. The database character set AL32UTF8 supports all the translated versions of Oracle Application Express.
You can manually install translated versions of Oracle Application Express using SQL*Plus. The installation files are encoded in AL32UTF8.
|
Note: Regardless of the target database character set, to install a translated version of Oracle Application Express, you must set the character set value of theNLS_LANG environment variable to AL32UTF8 before starting SQL*Plus. |
The following examples illustrate valid NLS_LANG settings for loading Oracle Application Express translations:
American_America.AL32UTF8 Japanese_Japan.AL32UTF8
Whether you are installing for the first time or upgrading from a previous release, you must run the load_lang.sql script to run a translated version of Oracle Application Express.
The installation scripts are located in subdirectories identified by a language code in the unzipped distribution apex/builder. For example, the German version is located in apex/builder/de and the Japanese version is located in apex/builder/ja. Within each of directory, there is a language loading script identified by the language code (for example, load_de.sql or load_ja.sql).
To install a translated version of Oracle Application Express:
Set the NLS_LANG environment variable, making sure that the character set is AL32UTF8. For example:
Bourne or Korn shell:
NLS_LANG=American_America.AL32UTF8 export NLS_LANG
C shell:
setenv NLS_LANG American_America.AL32UTF8
For Windows based systems:
set NLS_LANG=American_America.AL32UTF8
Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. For example:
On Windows:
SYSTEM_DRIVE:\ sqlplus /nolog SQL> CONNECT SYS as SYSDBA Enter password: SYS_password
On UNIX and Linux:
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
Execute the following statement:
ALTER SESSION SET CURRENT_SCHEMA = APEX_030200;
Execute the appropriate language specific script. For example:
@load_lang.sql
Where lang is the specific language (for example, load_de.sql for German or load_ja.sql for Japanese).
JOB_QUEUE_PROCESSES determine the maximum number of concurrently running jobs. In Oracle Application Express release 3.2, transactional support and SQL scripts require jobs. If JOB_QUEUE_PROCESSES is not enabled and working properly, you cannot successfully execute a script.
Topics in this section include:
There are currently three ways to view the number of JOB_QUEUE_PROCESSES:
In the installation log file
On the About Application Express page in Oracle Application Express
From SQL*Plus
After installing or upgrading Oracle Application Express to release 3.2, you can view the number of JOB_QUEUE_PROCESSES in the installation log files. See "Reviewing a Log of an Installation Session".
You can also view the number of JOB_QUEUE_PROCESSES on the About Application Express page.
To view the About Application Express page:
Log in to Oracle Application Express. See "Logging in to Your Oracle Application Express Workspace".
On the Administration list, click About Application Express.
The current number JOB_QUEUE_PROCESSES displays at the bottom of the page.
You can change the number of JOB_QUEUE_PROCESSES by running a SQL statement in SQL*Plus:
To update the number of JOB_QUEUE_PROCESSES:
Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role:
On Windows:
SYSTEM_DRIVE:\ sqlplus /nolog SQL> CONNECT SYS as SYSDBA Enter password: SYS_password
On UNIX and Linux:
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
In SQL*Plus run the following SQL statement:
ALTER SYSTEM SET JOB_QUEUE_PROCESSES = <number>
For example, running the statement ALTER SYSTEM SET JOB_QUEUE_PROCESSES = 20 sets JOB_QUEUE_PROCESSES to 20.
The PlsqlDatabasePassword parameter specifies the password for logging in to the database. You can use the dadTool.pl utility to obfuscate passwords in the dads.conf file.
You can find the dadTool.pl utility in the following directory:
For UNIX and Linux based systems:
ORACLE_BASE/ORACLE_HTTPSERVER_HOME/Apache/modplsql/conf
For Windows based systems:
ORACLE_BASE\ORACLE_HTTPSERVER_HOME\Apache\modplsql\conf
You access the Oracle Application Express home page by logging in to workspace using a Web browser. Your Web browser must support JavaScript and the HTML 4.0 and CSS 1.0 standards. See "Browser Requirement".
A workspace is a virtual private database allowing multiple users to work within the same Oracle Application Express installation while keeping their objects, data and applications private. Each workspace has a unique ID and name.
An Oracle Application Express administrator can create a workspace manually within Oracle Application Express Administration Services or have users submit requests. Oracle Application Express Administration Services is a separate application for managing an entire Oracle Application Express instance. See "Creating Workspaces" and "Managing Workspace Requests" in Oracle Application Express Administration Guide.

Note that instructions do not apply if you are running Oracle HTTP Server distributed with Oracle9i Release 2. To learn more, see "Configuring Oracle HTTP Server Distributed with Oracle9i Release 2".
|
Note: Within the context of this section, the Oracle home directory (ORACLE_HTTPSERVER_HOME) is the location where Oracle HTTP Server is installed. |
Oracle Application Express requires an Oracle database that is release 9.2.0.3 or later. To learn more, see the Oracle Database Installation Guide for your operating environment and "Recommended Pre-installation Tasks".
Perform the following postinstallation steps if:
This is a new installation of Oracle Application Express (that is, you are not upgrading from a previous release)
You are running Oracle HTTP Server distributed with Oracle Database Release 9.0.3.
Oracle HTTP Server is installed in an Oracle home.
Topics in this section include:
|
Note: Within the context of this section, the Oracle home directory (ORACLE_HTTPSERVER_HOME) is the location where Oracle HTTP Server is installed. |
First, change the password for the Oracle Application Express ADMIN account.
To change the password for the ADMIN account:
Change your working directory to ORACLE_BASE\ORACLE_HOME\apex or whatever convention used to indicate the Oracle home.
Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS. For example:
On Windows:
SYSTEM_DRIVE:\ sqlplus /nolog SQL> CONNECT SYS as SYSDBA Enter password: SYS_password
On UNIX and Linux:
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
Run apxchpwd.sql. For example:
@apxchpwd.sql
When prompted enter a password for the ADMIN account.
When configuring Oracle HTTP Server for Oracle Application Express in a new installation, the database user APEX_PUBLIC_USER must be an unlocked account. To unlock the account for database user APEX_PUBLIC_USER, execute the following steps:
Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS. For example:
On Windows:
SYSTEM_DRIVE:\ sqlplus /nolog SQL> CONNECT SYS as SYSDBA Enter password: SYS_password
On UNIX and Linux:
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
Run the following statement:
ALTER USER APEX_PUBLIC_USER ACCOUNT UNLOCK
In order to specify the password in the DAD file, you have to change the password for the database user APEX_PUBLIC_USER. Please use the following steps to change the password for the APEX_PUBLIC_USER database user:
Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS. For example:
On Windows:
SYSTEM_DRIVE:\ sqlplus /nolog SQL> CONNECT SYS as SYSDBA Enter password: SYS_password
On UNIX and Linux:
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
Run the following statement:
SQL> PASSWORD APEX_PUBLIC_USER Changing password for APEX_PUBLIC_USER New password: password Retype new password: password
In the default profile in Oracle Database 11g, the parameter PASSWORD_LIFE_TIME is set to 180. If you are using Oracle Database 11g with Oracle Application Express, this causes the password for APEX_PUBLIC_USER to expire in 180 days. As a result, your Oracle Application Express instance will become unusable until you change the password.
To prevent this behavior, create another profile in which the PASSWORD_LIFE_TIME parameter is set to unlimited and alter the APEX_PUBLIC_USER account and assign it the new profile.
|
See Also: Oracle Database Security Guide for information on creating profiles and assigning them to database users. |
To create the DAD, you modify the wdbsvr.app file and add an entry for Oracle Application Express.
To modify the wdbsvr.app file:
Use a text editor and open the wdbsvr.app file:
On Windows, see:
ORACLE_HTTPSERVER_HOME\Apache\modplsql\cfg\wdbsvr.app
On UNIX and Linux, see:
ORACLE_HTTPSERVER_HOME/Apache/modplsql/cfg/wdbsvr.app
Add an entry for Oracle Application Express using the following syntax. Only change the settings indicated in italics.
[DAD_apex] connect_string = localhost:1521:orcl password = apex username = apex_public_user default_page = apex document_table = wwv_flow_file_objects$ document_path = docs document_proc = wwv_flow_file_mgr.process_download reuse = Yes enablesso = No stateful = STATELESS_RESET nls_lang = American_America.AL32UTF8
Where:
connect_string refers to the host ID, port number, and Oracle9i database where Oracle Application Express was installed. Use the format host:port:sid.
If the Oracle9i version of Oracle HTTP Server you want to use is installed in the same Oracle home as the database you specified for use with Oracle Application Express, leave this parameter blank.
password is the password you changed for the APEX_PUBLIC_USER. See "Change the Password for the APEX_PUBLIC_USER Database User".
nls_lang determines the language setting of the DAD. The character set portion of the nls_lang value must always be set to AL32UTF8, regardless of whether or not the database character set is AL32UTF8.
If either the territory portion or the language portion of the NLS settings contains a space, you must wrap the value in double quotes as shown in the following example:
nls_lang = "ENGLISH_UNITED KINGDOM.AL32UTF8"
You can find information about your database's NLS settings by querying the view NLS_DATABASE_PARAMETERS as shown in the following example:
SELECT parameter,value
FROM nls_database_parameters
WHERE PARAMETER IN ('NLS_CHARACTERSET','NLS_LANGUAGE','NLS_TERRITORY');
Leave the remaining settings, including the user name setting, as they appear in the previous example.
Save and exit the wdbsvr.app file.
You must modify the httpd.conf file to include an alias that points to the file system path where you copied the images directory. You may also need to modify the httpd.conf file to add two new MIME types to support SQL Workshop.
To modify httpd.conf file:
Use a text editor and open the httpd.conf file:
On Windows:
ORACLE_HTTPSERVER_HOME\Apache\Apache\conf\httpd.conf
On UNIX and Linux:
ORACLE_HTTPSERVER_HOME/Apache/Apache/conf/httpd.conf
Add an alias entry that points to the file system path where you copied the images directory.
Windows example:
Alias /i/ "C:\oracle\ora92\Apache\Apache\images/"
UNIX and Linux example:
Alias /i/ "/home/oracle/OraHome1/Apache/Apache/images/"
Note that the previous examples assume you specified the image directory alias as /i/ when you ran the apexins.sql script.
Note you must include the forward slash (/) at the end of the path.
Next, add the following two lines to support SQL Workshop if they do not currently exist:
AddType text/xml xbl AddType text/x-component htc
If you are upgrading from Oracle HTML DB 2.0 or later, these MIME types should already exist.
Save and exit the httpd.conf file.
To stop and restart Oracle HTTP Server:
On Windows, Stop and restart Oracle HTTP Server:
Stop Oracle HTTP Server - From the Start menu, select Programs, Oracle - OraHome, Oracle HTTP Server, and Stop HTTP Server.
Restart Oracle HTTP Server - From the Start menu, select Programs, Oracle - OraHome, Oracle HTTP Server, and Start HTTP Server.
On UNIX and Linux, execute the following commands:
ORACLE_HTTPSERVER_HOME/Apache/Apache/bin/apachectl stop ORACLE_HTTPSERVER_HOME/Apache/Apache/bin/apachectl start
Note that if the Oracle HTTP Server is listening on a port less than 1024, then these commands must be executed as a privileged user (such as root).
Whether you are loading a new installation or upgrading from a previous release, you must copy the images directory from the top level of the ORACLE_BASE\ORACLE_HOME\apex directory to the location on the file system containing the Oracle home for Oracle HTTP Server.
|
Note: This section is relevant only if your plan to run Oracle Application Express with Oracle HTTP Server with mod_plsql. |
Topics in this section include:
During an upgrade, you must overwrite your existing images directory. Before you begin the upgrade, to ensure that you can revert to the previous version, Oracle recommends that you create a copy of your existing images directory for Oracle Application Express, indicating the release number of the images (for example, images_3_1).
To locate the images directory on the file system, review the httpd.conf file for the text alias /i/:
When you locate the images directory path, Oracle recommends that you copy the existing images directory to a backup location. Doing this allows you to revert to the previous release, if that becomes necessary.
After you copy the existing images directory, use the following command syntax to copy the apex\images directory from the Oracle database home to the existing images directory path, overwriting the existing images:
On Windows:
xcopy /E /I ORACLE_HOME\apex\images ORACLE_HTTPSERVER_HOME\Apache\images
On UNIX and Linux:
cp -rf $ORACLE_HOME/apex/images ORACLE_HTTPSERVER_HOME/Apache
In the preceding syntax examples:
ORACLE_HOME is the Oracle Database Oracle home
ORACLE_HTTPSERVER_HOME is the existing Oracle Application Server or Oracle HTTP Server Oracle home
After installation, copy the directory apex/images.
You can copy the images directory using Windows Explorer, or running a command from a command prompt similar to the following:
On Windows:
xcopy /E /I ORACLE_HOME\apex\images ORACLE_HTTPSERVER_HOME\Apache\images
On UNIX and Linux:
cp -rf $ORACLE_HOME/apex/images ORACLE_HTTPSERVER_HOME/Apache
In the preceding syntax example:
ORACLE_HOME is the Oracle Database Oracle home
ORACLE_HTTPSERVER_HOME is the existing Oracle HTTP Server Oracle home
By default, the ability to interact with network services is disabled in Oracle Database 11g release 1 (11.1). Therefore, if you are running Oracle Application Express with Oracle Database 11g release 1 (11.1), you must use the new DBMS_NETWORK_ACL_ADMIN package to grant connect privileges to any host for the APEX_030200 database user. Failing to grant these privileges results in issues with:
Sending outbound mail in Oracle Application Express.
Users can call methods from the APEX_MAIL package, but issues arise when sending outbound email.
Using Web services in Oracle Application Express.
PDF/report printing.
Searching for content in online Help (that is, using the Find link).
Topics in this section include:
|
Tip: To run the examples described in this section, the compatible initialization parameter of the database must be set to at least 11.1.0.0.0. By default an 11g database will already have the parameter set properly, but a database upgraded to 11g from a prior version may not. See "Creating and Configuring an Oracle Database" in Oracle Database Administrator's Guide for information about changing database initialization parameters. |
The following example demonstrates how to grant connect privileges to any host for the APEX_030200 database user. This example assumes you connected to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role.
DECLARE

Once the ACL has been fixed, you must run the first script in this section to apply the ACL to the APEX_030200 user. See "Granting Connect Privileges".
Oracle highly recommends you configure and use a Secure Sockets Layer (SSL) to ensure that passwords and other sensitive data are not transmitted in clear text in HTTP requests. Without the use of SSL, passwords could potentially be exposed, compromising security.
SSL is an industry standard protocol that uses RSA public key cryptography in conjunction with symmetric key cryptography to provide authentication, encryption, and data integrity.
The Oracle Application Express interface is translated into German, Spanish, French, Italian, Japanese, Korean, Brazilian Portuguese, Simplified Chinese, and Traditional Chinese. A single instance of Oracle Application Express can be installed with one or more of these translated versions. At runtime, each user's Web browser language settings determine the specific language version.
The translated version of Oracle Application Express should be loaded into a database that has a character set that supports the specific language. If you attempt to install a translated version of Oracle Application Express into a database that does not support the character encoding of the language, the installation may fail or the translated Oracle Application Express instance may appear corrupt when run. The database character set AL32UTF8 supports all the translated versions of Oracle Application Express.
You can manually install translated versions of Oracle Application Express using SQL*Plus. The installation files are encoded in AL32UTF8.
|
Note: Regardless of the target database character set, to install a translated version of Oracle Application Express, you must set the character set value of theNLS_LANG environment variable to AL32UTF8 before starting SQL*Plus. |
The following examples illustrate valid NLS_LANG settings for loading Oracle Application Express translations:
American_America.AL32UTF8 Japanese_Japan.AL32UTF8
Whether you are installing for the first time or upgrading from a previous release, you must run the load_lang.sql script to run a translated version of Oracle Application Express.
The installation scripts are located in subdirectories identified by a language code in the unzipped distribution apex/builder. For example, the German version is located in apex/builder/de and the Japanese version is located in apex/builder/ja. Within each of directory, there is a language loading script identified by the language code (for example, load_de.sql or load_ja.sql).
To install a translated version of Oracle Application Express:
Set the NLS_LANG environment variable, making sure that the character set is AL32UTF8. For example:
Bourne or Korn shell:
NLS_LANG=American_America.AL32UTF8 export NLS_LANG
C shell:
setenv NLS_LANG American_America.AL32UTF8
For Windows based systems:
set NLS_LANG=American_America.AL32UTF8
Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. For example:
On Windows:
SYSTEM_DRIVE:\ sqlplus /nolog SQL> CONNECT SYS as SYSDBA Enter password: SYS_password
On UNIX and Linux:
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
Execute the following statement:
ALTER SESSION SET CURRENT_SCHEMA = APEX_030200;
Execute the appropriate language specific script. For example:
@load_lang.sql
Where lang is the specific language (for example, load_de.sql for German or load_ja.sql for Japanese).
JOB_QUEUE_PROCESSES determine the maximum number of concurrently running jobs. In Oracle Application Express release 3.2, transactional support and SQL scripts require jobs. If JOB_QUEUE_PROCESSES is not enabled and working properly, you cannot successfully execute a script.
Topics in this section include:
There are currently three ways to view the number of JOB_QUEUE_PROCESSES:
In the installation log file
On the About Application Express page in Oracle Application Express
From SQL*Plus
After installing or upgrading Oracle Application Express to release 3.2, you can view the number of JOB_QUEUE_PROCESSES in the installation log files. See "Reviewing a Log of an Installation Session".
You can also view the number of JOB_QUEUE_PROCESSES on the About Application Express page.
To view the About Application Express page:
Log in to Oracle Application Express. See "Logging in to Your Oracle Application Express Workspace".
On the Administration list, click About Application Express.
The current number JOB_QUEUE_PROCESSES displays at the bottom of the page.
You can change the number of JOB_QUEUE_PROCESSES by running a SQL statement in SQL*Plus:
To update the number of JOB_QUEUE_PROCESSES:
Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role:
On Windows:
SYSTEM_DRIVE:\ sqlplus /nolog SQL> CONNECT SYS as SYSDBA Enter password: SYS_password
On UNIX and Linux:
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
In SQL*Plus run the following SQL statement:
ALTER SYSTEM SET JOB_QUEUE_PROCESSES = <number>
For example, running the statement ALTER SYSTEM SET JOB_QUEUE_PROCESSES = 20 sets JOB_QUEUE_PROCESSES to 20.
The PlsqlDatabasePassword parameter specifies the password for logging in to the database. You can use the dadTool.pl utility to obfuscate passwords in the dads.conf file.
You can find the dadTool.pl utility in the following directory:
For UNIX and Linux based systems:
ORACLE_BASE/ORACLE_HTTPSERVER_HOME/Apache/modplsql/conf
For Windows based systems:
ORACLE_BASE\ORACLE_HTTPSERVER_HOME\Apache\modplsql\conf
You access the Oracle Application Express home page by logging in to workspace using a Web browser. Your Web browser must support JavaScript and the HTML 4.0 and CSS 1.0 standards. See "Browser Requirement".
A workspace is a virtual private database allowing multiple users to work within the same Oracle Application Express installation while keeping their objects, data and applications private. Each workspace has a unique ID and name.
An Oracle Application Express administrator can create a workspace manually within Oracle Application Express Administration Services or have users submit requests. Oracle Application Express Administration Services is a separate application for managing an entire Oracle Application Express instance. See "Creating Workspaces" and "Managing Workspace Requests" in Oracle Application Express Administration Guide.

This chapter provides an overview of installing Oracle Application Express and describes issues to consider before installing.
This chapter contains these topics:
The installation process consists of four parts:
Plan your installation: This chapter offers an overview of the steps required to install Oracle Application Express. During the planning phase, you should also determine whether to install a full development environment or runtime environment.
A full development environment provides complete access to the Application Builder environment to develop applications. A runtime environment is an appropriate choice for production implementations in which you want to run applications that cannot be modified. To learn more, see "About the Oracle Application Express Runtime Environment".
Verify installation requirements: "Oracle Application Express Installation Requirements" describes the minimum requirements that your system must meet before you install the software.
Install the software: As described in Figure 1-1, the required installation steps depend upon:
How you install the Oracle Application Express. Available options include downloading a ZIP file from Oracle Technology Network (OTN), or using the version of Oracle Application Express that installs with Oracle Database 11g or later.
Which HTTP server you decide to use. Available options include the embedded PL/SQL gateway or Oracle HTTP Server and mod_plsql.
To learn more, see "About Choosing an HTTP Server".
Figure 1-1 Key Decision Points in the Installation Process
If you have version 1.5.0.00.33, 1.5.1.00.12, 1.6.0.00.87, 1.6.1.00.03, 2.0.0.00.49, 2.2.1.00.04, 3.0.0.00.20, 3.0.1.00.07, 3.0.1.00.08, 3.0.1.00.12, 3.1.0.00.32, 3.1.1.00.09 or 3.1.2.00.02 of Oracle Application Express, following any of the installation scenarios in this guide upgrades your Oracle Application Express instance to version 3.2 and creates Oracle Application Express 3.2 database objects in a new schema and migrates the application metadata to the new version.
For testing and production instances, Oracle Application Express supports the ability to install just a runtime version of Oracle Application Express. This runtime environment minimizes the installed footprint and privileges and improves application security since in a runtime instance developers cannot advertently update a production application.
An Oracle Application Express runtime environment enables you to run production applications, but it does not provide a Web interface for administration. A runtime environment only includes the packages necessary to run your application, making it a more hardened environment. You administer the Oracle Application Express runtime environment using SQL*Plus or SQL Developer and the APEX_INSTANCE_ADMIN API. To learn more see, "Managing a Runtime Environment" in Oracle Application Express Application Builder User's Guide.
Scripts are provided to remove or add the developer interface from an existing instance. To learn more, see "About the Oracle Application Express Runtime Environment" in "Downloading from Oracle Technology Network" and "Configuration Tasks When Installing from the Database".
In order to run, Oracle Application Express must have access to either Oracle HTTP Server and mod_plsql or the embedded PL/SQL gateway.
Topics in this section include:
Oracle HTTP Server uses the mod_plsql plug-in to communicate with the Oracle Application Express engine within the Oracle database. It functions as communication broker between the Web server and the Oracle Application Express objects in the Oracle database. More specifically, it maps browser requests into database stored procedure calls over a SQL*Net connection. The following graphic illustrates the Oracle Application Express architecture using Oracle HTTP Server and mod_plsql.
Note that this three tier architecture consists of the following components: a Web browser, Oracle HTTP Server (Apache) with mod_plsql, and an Oracle database containing Oracle Application Express.
Advantages of Oracle HTTP Server (Apache) with mod_plsql:
Separation of mid-tier for the database tier
Appropriate for Oracle Real Application Clusters (Oracle RAC) environments
In an Oracle HTTP Server or Oracle Application Server configuration, images are stored on the file system in the location referenced by the alias /i/. If you are upgrading Oracle Application Express from a prior release, you can locate the images directory on the file system, by reviewing the following files and searching for the text alias /i/:
Oracle9i HTTP Server Release 2—see the httpd.conf file.
Oracle HTTP Server distributed with Oracle Database 11g—see the dads.conf file.
Oracle Application Server 10g—see the marvel.conf file.
Specific examples for locating the text alias /i/ can be found in "Downloading from Oracle Technology Network" and "Configuration Tasks When Installing from the Database".
The embedded PL/SQL gateway installs with Oracle Database 11g. It provides the Oracle database with a Web server and also the necessary infrastructure to create dynamic applications. The embedded PL/SQL gateway runs in the Oracle XML DB HTTP server in the Oracle database and includes the core features of mod_plsql. The following graphic illustrates the Oracle Application Express architecture using the embedded PL/SQL gateway.
As shown in the previous graphic, the embedded PL/SQL gateway is a simple two tier architecture and consists of theses components: a Web browser and an Oracle database, containing the embedded PL/SQL and Oracle Application Express.
Advantages of the embedded PL/SQL gateway:
Ease of configuration
Included in the database
No separate server installation
The embedded PL/SQL gateway runs in the database as part of the XML DB HTTP Protocol Listener. The XML DB HTTP Protocol Listener and embedded PL/SQL gateway provides the equivalent core features of Oracle HTTP Server and mod_plsql. Because the HTTP Listener runs in the same database where Oracle Application Express is installed, it is not possible to separate the HTTP listener from the database. For this reason, it is not recommended to use the embedded PL/SQL gateway for applications that run on the Internet. Additionally, the embedded PL/SQL gateway does not provide the same flexibility of configuration and detailed logging as Oracle HTTP Server with mod_plsql.
When running Oracle Application Express with the embedded PL/SQL gateway, images are stored directly in the database within the Oracle XML DB repository. You can access images by using the WebDAV feature of Oracle XML DB or by using FTP. To learn more, see "Using Protocols to Access the Repository" in Oracle XML DB Developer's Guide.
When running Oracle Application Express in an Oracle Real Application Clusters (Oracle RAC) environment, Oracle recommends that you use Oracle HTTP Server with mod_plsql. Oracle HTTP Server with mod_plsql permits you to specify a connection in the service name format, so that one HTTP Server can access all nodes.
Oracle recommends that you do not select the embedded PL/SQL gateway option for Oracle RAC installations. The embedded PL/SQL gateway uses an HTTP Server built into the database instance, and because of this, it does not take advantage of the Oracle RAC shared architecture.
How you install Oracle Application Express depends upon where you install the software from and which HTTP server you decide to use. This section provides an overview of each installation scenario.

This section attempts to provide information for users who are accessing Oracle Application Express utilizing only a keyboard or Freedom Scientific's screen reader JAWS.
This section contains the following topics:
For additional information about the accessibility of Oracle products, see:
http://www.oracle.com/accessibility
|
Note: JAWS release 10.0.1139 with all default settings was used in writing this section. |
The following is a list of general accessibility violations in Oracle Application Express, followed by known workarounds where possible:
Some tables containing data are poorly marked up with appropriate summary information. This issue does not currently have a workaround.
In some situations, JAWS may interpret the contents of a layout table as a data table and when this happens, the table will be available in the JAWS buffer and navigable using the JAWS navigation quick key T. However due to the missing summary text, these are difficult to identify.
Some form items do not have a label tag describing the form item.
This issue does not currently have a workaround.
Some decorative images are missing an empty alt text.
This issue does not currently have a workaround.
Some non-decorative images are not accompanied by alt text.
This issue does not currently have a workaround.
Some region types contain layout tables (that is, tables with an empty summary attribute) that contain th tags.
This issue does not currently have a workaround.
If functionality is provided by XMLHTTP (AJAX) and DHTML scripting languages, screen readers may not properly interpret screen updates. In most, but not all cases, JAWS interprets the updates presented utilizing XMLHTTP. In the cases where updates are picked up, there is still a problem since JAWS does not notify the user of the update.
This issue does not currently have a workaround.
Some event handlers are not device independent.
For example, JAWS does have a mechanism to fire onmouseover events that can help with these types of event handlers.
To activate an onmouseover event handler in JAWS:
Move to the element that contains the onmouseover event. Note that you know if the element has this event handler if JAWS announces “on mouse over” on arrival.
Press CTRL+INSERT+ENTER to launch the mouseover event.
Some pages contain contextual Help within Show/Hide regions, which are hidden by default. This information is currently not accessible using keyboard navigation.
This issue does not currently have a workaround.
Tab orders do not always follow a logical order.
This issue does not currently have a workaround.
Some layout tables have no summary attribute.
This issue does not currently have a workaround.
Some tables containing data have an empty summary attribute.
This issue does not currently have a workaround.
Many of the pages in Oracle Application Express are form pages designed for maintaining application metadata. This section describes how you can gain an understanding of the structure of these pages and interact with them using a screen reader such as JAWS.
Topics in this section include:
Many form pages are logically broken up into different regions. For example, the Edit Page Item page has the following regions containing form fields for maintaining information about the page item:
Name
Displayed
Label
Element
Source
Default
LOV
Security
Conditions
Read Only
Help
Configuration
Comments
Unfortunately these page sections are not marked up with HEADERS (Hn) tags, therefore another approach is required to gain an understanding of this structure. At the top of the page, there are links that take the user directly to the region they wish to locate. There are contained within a division element. Additionally, there is Show All link as the first link in the set.
By understanding that links to each section exist in a division element, you can understand of the overall structure of the page using JAWS:
Press CTRL+HOME to go to the top of the page.
JAWS announces the page name, Edit Page Item.
Press CTRL+INSERT+ Z to load the Select a Division dialog box.
Press S repeatedly to go to the division that begins with Show All.
JAWS reads the contents of the division and in doing so gives you a list of all the regions on the page.
Press ENTER to navigate to the division.
Press DOWN ARROW to access each link for each region on the page.
To navigate to a particular region, press ENTER on the appropriate link.
Many pages in Oracle Application Express contain a Tasks region on the right-hand side of the page. For example, the Edit Page Item page has a Tasks region on the right side containing a list of links relevant to the current item type. There is no HEADER defined on this region currently.
To navigate to the Tasks region using JAWS:
Press CTRL+HOME to go to the top of the page.
JAWS announces the page name.
Press CTRL+F to launch the Find dialog box.
Type tasks and press ENTER.
Since Tasks links are implemented in a list, press the JAWS navigation quick key L once to navigate to the list.
Press the JAWS navigation quick key I to navigate through the list items and ENTER if you wish to activate a link.
This section describes how to use JAWS to access Page Help and Item-level help in Oracle Application Express.
Topics in this section include:
Many pages in Oracle Application Express have regions on the right side of the page containing Help text. This Help text describes basic concepts or decision points relevant to the current page. For example, the Edit Page Item page has a region on the top right of the page that reads as follows:
Page Items - Page items are HTML elements with associated session state. Page items can be rendered in many ways such as a text field, a check box, or a select list.
This text is contained within a table with empty summary text and has no HEADER. Navigation to this text is difficult. However, you can navigate to regions like this by searching for text which is similar to the page title. For example, if you were on the Edit Page Item page, you might search for the text Page Items.
To search for the text Page Items using JAWS:
Press the PLUS sign (+) on the numeric keypad to go back into Virtual PC Cursor mode.
Note: This step is not required if using JAWS 10 with Auto Forms Mode enabled.
Press CTRL+HOME to go to the top of the page.
JAWS announces the page name.
Press CTRL+F to launch the JAWS Find dialog box.
Type page items and press ENTER.
Once the text has been located, press DOWN ARROW to read the text.
Most items within the user interface have field-level Help available by activating or clicking on the field label. If Help text is available, the adjacent label will be implemented as a link, where the link text will match that of the current form item's label text. Activating this link will load a separate window containing the help text.
To access this field-level Help for an item using JAWS:
Press CTRL+HOME to go to the top of the page.
JAWS announces the page name.
Press INSERT+ F7 to load the Links List dialog box.
Press the first letter of the link text you wish to locate, repeatedly.
If there is no link text matching the label of the form item you wish to get help for, then there is no help available for that item
If the appropriate link is found, press ENTER to activate the link.
A separate window containing the Help text appears
Press the JAWS navigation quick key N to go to the help text.
Once you are finished reading the help text, press ALT+F4 to close the Help window and return to page.
If a validation fails when submitting a form, you are redirected back to the same page and an error message displays in a list at the top of the page. Additionally, error text displays inline next to the page item associated with the validation.
The following procedure explains how to identify when a validation fails, review error messages, and rectify the necessary values in order to pass the validation, all within the context of the Edit Page Item form page.
Topics in this section include:
When a validation fails, the same page loads with details of the failure. In this situation JAWS does not read the page as it would normally when loading a new page. You can quickly check if a validation error has occurred by searching for any images with an alt text of Error.
To check for images having an alt text of Error:
Press CTRL+HOME to go to the top of the page.
JAWS announces the page name.
Press CTRL+INSERT+G to launch the Select a Graphic dialog box.
Press E repeatedly to try and locate the error image. If there is an error image, then this means a validation has failed.
If a validation error occurs, a list appears at the top of the page and contains list items with the error text for the failed validations.
To navigate to the list containing error text:
Press CTRL+HOME to go to the top of the page.
JAWS announces the page name.
Press the JAWS navigation quick key L to go to the first list on the page.
JAWS will announce "list of x items" where x is the number of errors that has occurred.
Press the JAWS navigation quick key I to read through each error message.
There is no simple way to navigate from the summary list of error messages to the page item associated with the failed validation. One approach is to navigate to the error image that displays next to the associated page item and then use JAWS reading commands to understand which error you are dealing with.
To navigate to the error image:
Press CTRL+HOME to go to the top of the page.
JAWS announces the page name.
Press CTRL+INSERT+G to load the Select a Graphic dialog box.
Press E repeatedly to locate the error image.
Press ENTER to navigate to the error image.
Press DOWN ARROW once to go to the Help text link for the associated field.
This tells you which field has a validation error since the link text is the same as the form field label.
Press the DOWN ARROW again to go to the error message.
Press the JAWS navigation quick key F to go to the page item.
Press ENTER to enable Forms Mode and provide a new value.
Once you provide a new value and fix the error, you need to locate subsequent error images on the page.
To locate subsequent error messages on the page:
Press the PLUS sign (+) on the numeric keypad to go back into Virtual PC Cursor mode.
Press the JAWS navigation quick key G repeatedly until you locate the next error image.
JAWS announces "graphic error."
Once you have located the next error image, repeat steps 5 to 8 until all errors have been addressed.
Once all errors have been addressed, you need to click the Apply Changes button:
Press the JAWS navigation quick key B until you hear JAWS announce "Apply Changes Button."
Press ENTER to apply your changes.
If your changes fixed all the validation errors, you will be taken back to the 'Page Definition' page.
Oracle Application Express, release 3.1 included a new report region called interactive report. Interactive report regions enable users to alter the layout of report data by choosing columns and applying filters.
In Oracle Application Express release 3.2, interactive report regions are only utilized within the Oracle Application Express Application Migration module. Interactive report regions have a number of violations that strongly prohibits their usability with screen readers and keyboard-only users.
The following list explains these violations and includes known workarounds where possible:
The Actions menu is not accessible by a screen reader or by keyboard navigation.
This issue does not currently have a workaround.
The Search icon menu to the left of the Search region is not accessible by screen reader or by keyboard navigation.
This issue does not currently have a workaround.
The column headings used to sort, filter, group, exclude data, or display Help about data are not accessible by a screen reader or by keyboard navigation.
This issue does not currently have a workaround.
Interactive report regions produce a table with rows that do not contain a HEADER attribute linking to the id of the th tag for that column. Although the number of violations on interactive reports strongly prohibits their use with screen readers such as JAWS, this particular violation is not a major issue. This is because the data tables are fairly simple (nearly always where each cell is associated with only 1 HEADER and row) and do use the appropriate table markup (th and td elements). Thus, screen readers such as JAWS are able to announce the context of a particular cell.
The one exception is when a Control Break is defined on the data in the interactive report to group it. In this situation, an additional th element is generated for the column that the Control Break has been enabled. Because of the missing markup, it is therefore difficult to get the full context when navigating the cells of the table in this situation.
Flash charts do not provide alternative descriptive text.
This issue does not currently have a workaround.
An animated GIF is sometimes used to indicate processing is underway (for example, when filtering a report or loading a chart). This information is not available in a non-animated presentation mode.
This issue does not currently have a workaround.
Some Form items in AJAX-based dialog boxes do not have associated label tags.
This issue does not currently have a workaround.
The layout table used for the Search tab has no summary attribute. Although the number of violations on interactive reports strongly prohibits their use with screen readers such as JAWS, this particular violation is not a major issue. Screen readers such as JAWS do not pick this up as a data table.
The table containing data has an empty summary attribute. This issue does not currently have a workaround.
Due to the contents of the table, screen readers such as JAWS do pick this up as a data table. It is therefore available in the screen reader's buffer and navigable using the JAWS navigation quick key T. However due to the empty summary text, it is difficult to identify.
Because interactive reports requires functionality provided by the XMLHTTP (AJAX) and DHTML scripting languages, screen readers may not properly interpret screen updates. For example, in some cases screen readers such as JAWS pick up the updates presented using XMLHTTP. Even if updates are picked up, JAWS does not announce the update.
This issue does not currently have a workaround.
As described in "Issues with Interactive Report Regions", some features in Interactive Reports are not available to keyboard-only users. This section describes some basic features that are available by tabbing through the focusable elements on the page.
Topics in this section include:
All interactive reports feature a Search field at the top of the page. This Search field is a standard text item.
To execute a search using a keyboard:
Press TAB repeatedly to navigate to the Search field.
Type keywords in the Search field.
Press ENTER to invoke the search. Alternatively, you can also press TAB to navigate to the Go button and then press ENTER.
The Rows select list displays to the right of the Search field at the top of the page and controls the number of rows that display in the report. This is a standard select list.
To use the Rows list using a keyboard:
Press TAB to navigate to the Rows list.
Press Down Arrow or Up Arrow to make a selection.
Press TAB to navigate to the Go button and then press ENTER.
Some interactive reports in Oracle Application Express Application Migration Workshop contain form items for applying bulk updates to components (for example, the Blocks page). All form items within the report and buttons to apply the changes are keyboard accessible. Also some pages feature a check box in the first row to perform bulk processing and corresponding Select All and Deselect All links below the report. All of these items are keyboard accessible.
All the interactive reports Oracle Application Express Application Migration Workshop contain at least one link to edit or view a specific sub-components. These are all standard links and are therefore keyboard accessible.
When an existing search filter is applied to an interactive report, a search filter displays below the Search bar.
You can access the search filter using the keyboard to:
Edit the search filter.
Press TAB to navigate to the search filter and then press ENTER to open the Filter dialog box. Since the focus does not move automatically to the dialog box, press SHIFT+TAB until you reach the appropriate controls.
Disable or enable the search filter.
Press TAB to navigate to the check box to the right of the filter and SPACEBAR to disable or enable the filter.
Delete the search filter.
Press TAB to navigate to the search filter and then ENTER to open the Filter dialog box. Press TAB or SHIFT+TAB to navigate to the Delete button and then press ENTER.
This chapter describes the requirements for installing Oracle Application Express.
This chapter contains these topics:
Oracle Application Express version 3.2 requires an Oracle database that is release 9.2.0.3 or later.
|
Note: You can upgrade the version of Oracle Application Express in Oracle Database Express Edition 10g Release 2 (10.2), by installing Oracle Application Express version 3.2. For more information, see the Oracle Application Express page on Oracle Technology Network (OTN). |
If you plan to run Oracle Application Express with an Oracle database earlier than Oracle Database 10g release 1 (10.1), you must install Oracle Java Virtual Machine (JVM). To learn more, see the Oracle Database Installation Guide for your operating environment.
|
Note: Ignore this requirement if your configuration uses non-null values for the database initialization parametersSGA_TARGET (in Oracle Database 10g and 11g) or MEMORY_TARGET (in Oracle Database 11g). |
Oracle Application Express requires the shared_pool_size of the target database to be at least 100 MB.
To check the shared_pool_size of the target database:
Start the database:
SQL> STARTUP
If necessary, enter the following command to determine whether the system uses an initialization parameter file (initsid.ora) or a server parameter file (spfiledbname.ora):
SQL> SHOW PARAMETER PFILE;
This command displays the name and location of the server parameter file or the initialization parameter file.
Determine the current values of the shared_pool_size parameter:
SQL> SHOW PARAMETER SHARED_POOL_SIZE
If the system is using a server parameter file, set the value of the SHARED_POOL_SIZE initialization parameter to at least 100 MB:
SQL> ALTER SYSTEM SET SHARED_POOL_SIZE='100M' SCOPE=spfile;
If the system uses an initialization parameter file, change the values of the SHARED_POOL_SIZE parameter to at least 100 MB in the initialization parameter file (initsid.ora).
Shut down the database:
SQL> SHUTDOWN
Restart the database:
SQL> STARTUP
To view or develop Oracle Application Express applications, Web browsers must support Java Script and the HTML 4.0 and CSS 1.0 standards. The following browsers meet these requirements:
Microsoft Internet Explorer 6.0 or later version
Firefox 1.0 or later
In order to run, Oracle Application Express must have access to one of the following:
Embedded PL/SQL gateway
Oracle HTTP Server and mod_plsql
Oracle XML DB HTTP Server with the embedded PL/SQL gateway installs with Oracle Database 11g. It provides the database with a Web server and the necessary infrastructure to create dynamic applications.
Oracle HTTP Server uses the mod_plsql plug-in to communicate with the Oracle Application Express engine within the Oracle database. The following products include appropriate versions of HTTP Server and mod_plsql:
Oracle9i release 2 (9.2) or later
Oracle9i Application Server release 1 (1.0.2.2) or later
Oracle Database 10g Companion CD release 1 or 2

Oracle XML DB must be installed in the Oracle database that you want to use. If you are using a preconfigured database created either during an installation or by Database Configuration Assistant (DBCA), Oracle XML DB is already installed and configured.
|
See Also: Oracle XML DB Developer's Guide for more information about manually adding Oracle XML DB to an existing database |
|
Tip: The installer does a prerequisite check for Oracle XML DB and will exit if it is not installed. |
Oracle Text must be installed in order to use the searchable online Help in Oracle Application Express. By default, Oracle Text is installed as part of Oracle Database.
In addition, ensure that the default language preferences for Oracle Text have been installed. To install the Oracle Text default language, log in to the Oracle database where you plan to install Oracle Application Express and run the appropriate drdeflang.sql script, which by default is located in ORACLE_BASE\ORACLE_HOME\ctx\admin\defaults. For example, to run the language preferences script for US English, drdefus.sql:
jstraub: c:\> sqlplus /nolog
SQL> connect ctxsys
Enter password: password
SQL> @c:\oracle\product\10.2.0\db_1\ctx\admin\defaults\drdefus.sql
|

Available options include downloading a ZIP file from Oracle Technology Network (OTN), or using the version of Oracle Application Express that installs with Oracle Database 11g or later. Then, you must decide which HTTP server to use. Available options include the embedded PL/SQL gateway or Oracle HTTP Server and This illustration graphically depicts the architecture of Oracle Application Express when using the embedded PL/SQL gateway. This graphic shows two items: a Web browser and an Oracle database which contains both the embedded PL/SQL gateway and the Application Express engine. An arrow points from the Web browser to the Oracle Database and another arrow points from the Oracle database to the Web browser. This illustration graphically depicts the architecture of Oracle Application Express when using Oracle HTTP Server with This chapter describes how to install Oracle Application Express by downloading a ZIP file from Oracle Technology Network (OTN) and completing the appropriate postinstallation tasks. The instructions in this chapter apply to both new and upgrade installations. To learn more, see "Upgrading from a Previous Version of Oracle Application Express". This chapter contains these topics: Before installing Oracle Application Express, Oracle recommends that you complete the following steps: Review and satisfy all Oracle Application Express installation requirements. See "Oracle Application Express Installation Requirements". Shut down any existing Oracle Database instances with normal or immediate priority, except for the database where you plan to install the Oracle Application Express schemas. On Oracle Real Application Clusters (Oracle RAC) systems, shut down all instances on each node. If Automatic Storage Management (ASM) is running, shut down all databases that use ASM except for the database where you will install Oracle Application Express, and then shut down the ASM instance. You can use the Windows Services utility, located either in the Windows Control Panel or from the Administrative Tools menu (under Start and then Programs), to shut down Oracle Database and ASM instances. Names of Oracle databases are preceded with Back up the Oracle Database installation. Oracle recommends that you create a backup of the current installation of Oracle Database installation before you install Oracle Application Express. You can use Oracle Database Recovery Manager, which is included the Oracle Database installation, to perform the backup. Start the Oracle Database instance that contains the target database. After backing up the system, you must start the Oracle instance that contains the target Oracle database. Do not start other processes such as the listener or Oracle HTTP Server. However, if you are performing a remote installation, make sure the database listener for the remote database has started. In order to run, Oracle Application Express must have access to either the embedded PL/SQL gateway or Oracle HTTP Server and This section describes how to install Oracle Application Express by downloading a ZIP file from OTN and then configuring the embedded PL/SQL gateway.

This appendix contains the third party license for Apache. Oracle Application Express is installed by default with Oracle Database 11g. This chapter describes required postinstallation configuration tasks for Oracle Application Express when installed with Oracle Database 11g or later. The instructions in this chapter apply to both new and upgrade installations. To learn more, see "Upgrading from a Previous Version of Oracle Application Express". This chapter contains these topics: Installing from the Database and Configure the Embedded PL/SQL Gateway Installing from the Database and Configure Oracle HTTP Server If you are already running Oracle Application Express, then check the Oracle Application Express page on the Oracle Technology Network (OTN) at the following URL for information about patch set releases or later versions of Oracle Application Express: Upgrading to Oracle Database 11g will not patch Oracle Application Express. To learn more about downloading and installing Oracle Application Express from Oracle Technology Network (OTN) see "Downloading from Oracle Technology Network". Before installing Oracle Application Express, Oracle recommends that you complete the following steps: Review and satisfy all Oracle Application Express installation requirements. See "Oracle Application Express Installation Requirements". Shut down any existing Oracle Database instances as well as Oracle-related processes. Shut down any existing Oracle Database instances with normal or immediate priority, except for the database where you plan to install the Oracle Application Express schemas. On Oracle Real Application Clusters (Oracle RAC) systems, shut down all instances on each node. If Automatic Storage Management (ASM) is running, shut down all databases that use ASM except for the database where you will install Oracle Application Express, and then shut down the ASM instance. You can use the Windows Services utility, located either in the Windows Control Panel or from the Administrative Tools menu (under Start and then Programs), to shut down Oracle Database and ASM instances. Names of Oracle databases are preceded with Back up the Oracle Database installation. Oracle recommends that you create a backup of the current installation of Oracle Database installation before you install Oracle Application Express. You can use Oracle Database Recovery Manager, which is included the Oracle Database installation, to perform the backup. Start the Oracle Database instance that contains the target database. After backing up the system, you must start the Oracle instance that contains the target Oracle database. Do not start other processes such as the listener or Oracle HTTP Server. However, if you are performing a remote installation, make sure the database listener for the remote database has started. In order to run, Oracle Application Express must have access to either the embedded PL/SQL gateway or Oracle HTTP Server and This section describes required postinstallation configuration tasks when running Oracle Application Express with the embedded PL/SQL gateway. Topics in this section include: Install the Oracle Database and Complete Pre-installation Tasks Enable Indexing of Online Help in Oracle Database 11g Release 2 and Higher Oracle Application Express automatically installs with Oracle Database 11g or later. To learn more about install the Oracle Database, see the Oracle Database Installation Guide for your operating environment and "Recommended Pre-installation Tasks". Although the embedded PL/SQL gateway installs with the Oracle Database 11g, you must configure it before you can use it with Oracle Application Express. To accomplish, you run a configuration file and unlock the Note: Topics in this section include: In a new installation, you configure the embedded PL/SQL gateway by running the configuration script Note: To run the Change your working directory to Start SQL*Plus and connect to the database where Oracle Application Express is installed as On Windows: On UNIX and Linux: Run When prompted, enter a password for the Application Express Admin account. Be sure to make a note of the password you enter. You will use this password to log in to Oracle Application Express Administration Services. When prompted, enter the port for the Oracle XML DB HTTP server. The default port number is 8080. Enter the following statement to unlock the ANONYMOUS account: The embedded PL/SQL gateway runs in the Oracle XML DB HTTP server in the Oracle database. You can determine if the Oracle XML DB HTTP server is enabled by verifying the associated port number. To verify the port number where the Oracle XML DB HTTP Server is running: Start SQL*Plus and connect to the database where Oracle Application Express is installed as On Windows: On UNIX and Linux: Enter the following statement to verify the port number: If the port number returns To enable it, follow the instructions in "Enabling Oracle XML DB HTTP Server". The embedded PL/SQL gateway runs in the Oracle XML DB HTTP server in the Oracle database. To enable Oracle XML DB HTTP server: Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS. For example: Windows: UNIX and Linux: Run the following statements: For example: Note: "Using Protocols to Access the Repository" and "Using HTTP(S) on Nonstandard Ports" in Oracle XML DB Developer's Guide. "Protocol Address Configuration" and "Port Number Limitations" in Oracle Database Net Services Reference. The embedded PL/SQL gateway runs in the Oracle XML DB HTTP server in the Oracle database. To disable Oracle XML DB HTTP server: Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS.

Without the use of SSL, passwords could potentially be exposed, compromising security. SSL is an industry standard protocol that uses RSA public key cryptography in conjunction with symmetric key cryptography to provide authentication, encryption, and data integrity. The Oracle Application Express interface is translated into German, Spanish, French, Italian, Japanese, Korean, Brazilian Portuguese, Simplified Chinese, and Traditional Chinese. A single instance of Oracle Application Express can be installed with one or more of these translated versions. At runtime, each user's Web browser language settings determine the specific language version. The translated version of Oracle Application Express should be loaded into a database that has a character set that supports the specific language. If you attempt to install a translated version of Oracle Application Express into a database that does not support the character encoding of the language, the installation may fail or the translated Oracle Application Express instance may appear corrupt when run. The database character set You can manually install translated versions of Oracle Application Express using SQL*Plus.

3.3.10 About Managing JOB_QUEUE_PROCESSES
JOB_QUEUE_PROCESSES determine the maximum number of concurrently running jobs. In Oracle Application Express release 3.2, transactional support and SQL scripts require jobs. If JOB_QUEUE_PROCESSES is not enabled and working properly, you cannot successfully execute a script.
3.3.10.1 Viewing the Number of JOB_QUEUE_PROCESSES
JOB_QUEUE_PROCESSES:
3.3.10.1.1 Viewing JOB_QUEUE_PROCESSES in the Installation Log File
JOB_QUEUE_PROCESSES in the installation log files. See "Reviewing a Log of an Installation Session".
3.3.10.1.2 Viewing JOB_QUEUE_PROCESSES in Oracle Application Express
JOB_QUEUE_PROCESSES on the About Application Express page.JOB_QUEUE_PROCESSES displays at the bottom of the page.
3.3.10.2 Changing the Number of JOB_QUEUE_PROCESSES
JOB_QUEUE_PROCESSES by running a SQL statement in SQL*Plus:JOB_QUEUE_PROCESSES:SYS specifying the SYSDBA role:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
ALTER SYSTEM SET JOB_QUEUE_PROCESSES = <number>
ALTER SYSTEM SET JOB_QUEUE_PROCESSES = 20 sets JOB_QUEUE_PROCESSES to 20.
3.3.11 Configuring the SHARED_SERVERS Parameter
SHARED_SERVERS database initialization parameter is set to a reasonable value (that is, not 0 or 1). For a small group of concurrent users, Oracle recommends a value of 5 for SHARED_SERVERS.SYS specifying the SYSDBA role. For example:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
ALTER SYSTEM SET SHARED_SERVERS = 5 SCOPE=BOTH;

3.4.8 Security Considerations
3.4.9 About Running Oracle Application Express in Other Languages
AL32UTF8 supports all the translated versions of Oracle Application Express.AL32UTF8.
NLS_LANG environment variable to AL32UTF8 before starting SQL*Plus.NLS_LANG settings for loading Oracle Application Express translations:
American_America.AL32UTF8
Japanese_Japan.AL32UTF8
3.4.9.1 Installing a Translated Version of Oracle Application Express
load_lang.sql script to run a translated version of Oracle Application Express.apex/builder. For example, the German version is located in apex/builder/de and the Japanese version is located in apex/builder/ja. Within each of directory, there is a language loading script identified by the language code (for example, load_de.sql or load_ja.sql).NLS_LANG environment variable, making sure that the character set is AL32UTF8. For example:
NLS_LANG=American_America.AL32UTF8
export NLS_LANG
setenv NLS_LANG American_America.AL32UTF8
set NLS_LANG=American_America.AL32UTF8
SYS specifying the SYSDBA role. For example:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
ALTER SESSION SET CURRENT_SCHEMA = APEX_030200;
@load_lang.sql
lang is the specific language (for example, load_de.sql for German or load_ja.sql for Japanese).
3.4.10 About Managing JOB_QUEUE_PROCESSES
JOB_QUEUE_PROCESSES determine the maximum number of concurrently running jobs. In Oracle Application Express release 3.2, transactional support and SQL scripts require jobs. If JOB_QUEUE_PROCESSES is not enabled and working properly, you cannot successfully execute a script.
3.4.10.1 Viewing the Number of JOB_QUEUE_PROCESSES
JOB_QUEUE_PROCESSES:
3.4.10.1.1 Viewing JOB_QUEUE_PROCESSES in the Installation Log File
JOB_QUEUE_PROCESSES in the installation log files. See "Reviewing a Log of an Installation Session".
3.4.10.1.2 Viewing JOB_QUEUE_PROCESSES in Oracle Application Express
JOB_QUEUE_PROCESSES on the About Application Express page.JOB_QUEUE_PROCESSES displays at the bottom of the page.
3.4.10.2 Changing the Number of JOB_QUEUE_PROCESSES
JOB_QUEUE_PROCESSES by running a SQL statement in SQL*Plus:JOB_QUEUE_PROCESSES:SYS specifying the SYSDBA role:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
ALTER SYSTEM SET JOB_QUEUE_PROCESSES = <number>
ALTER SYSTEM SET JOB_QUEUE_PROCESSES = 20 sets JOB_QUEUE_PROCESSES to 20.
3.4.11 About Obfuscating PlsqlDatabasePassword Parameter
PlsqlDatabasePassword parameter specifies the password for logging in to the database. You can use the dadTool.pl utility to obfuscate passwords in the dads.conf file.dadTool.pl utility in the following directory:
ORACLE_BASE/ORACLE_HTTPSERVER_HOME/Apache/modplsql/conf
ORACLE_BASE\ORACLE_HTTPSERVER_HOME\Apache\modplsql\conf
3.4.12 Create a Workspace and Add Oracle Application Express Users
3.4.12.1 Creating a Workspace Manually
ADMIN account and password created or reset during the installation process.mod_plsql, go to:
http://hostname:port/pls/apex/apex_admin
hostname is the name of the system where Oracle HTTP Server is installed.port is the port number assigned to Oracle HTTP Server. In a default installation, this number is 7777.pls is the indicator to use the mod_plsql cartridge.apex is the database access descriptor (DAD) defined in the mod_plsql configuration file.admin.
3.4.12.2 Creating Oracle Application Express Users
3.4.12.3 Logging in to Your Workspace
http://hostname:port/apex
hostname is the name of the system where Oracle XML DB HTTP server is installed.port is the port number assigned to Oracle XML DB HTTP server. In a default installation, this number is 8080.apex is the database access descriptor (DAD) defined in the configuration file.htmldb or something else. Verify your DAD with your Oracle Application Express administrator.
3.5 Post Installation Tasks for Upgrade Installations
3.5.1 Remove Prior Oracle Application Express Installations
3.5.1.1 Verify if a Prior Installation Exists
SYS. For example:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
SELECT username
FROM dba_users
WHERE (username LIKE 'FLOWS_%' OR USERNAME LIKE 'APEX_%')
AND USERNAME NOT IN (
SELECT 'FLOWS_FILES'
FROM DUAL
UNION
SELECT 'APEX_PUBLIC_USER' FROM DUAL
UNION
SELECT SCHEMA s
FROM dba_registry
WHERE comp_id = 'APEX');
FLOWS_XXXXXX or APEX_XXXXXX where XXXXXX represents six numbers, those entries are candidates for removal.
3.5.1.2 Remove Schemas f: rom Prior Installations
SYS specifying the SYSDBA role. For example:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
DROP USER FLOWS_030000 CASCADE;
3.5.2 Fix Invalid ACL in Oracle Database 11g
apex directory where you unzipped the installation software.SYS specifying the SYSDBA role. For example:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
EXEC DBMS_NETWORK_ACL_ADMIN.DELETE_PRIVILEGE('power_users.xml', 'FLOWS_030000');

For example, the German version is located in apex/builder/de and the Japanese version is located in apex/builder/ja. Within each of directory, there is a language loading script identified by the language code (for example, load_de.sql or load_ja.sql).NLS_LANG environment variable, making sure that the character set is AL32UTF8. For example:
NLS_LANG=American_America.AL32UTF8
export NLS_LANG
setenv NLS_LANG American_America.AL32UTF8
set NLS_LANG=American_America.AL32UTF8
SYS specifying the SYSDBA role. For example:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
ALTER SESSION SET CURRENT_SCHEMA = APEX_030200;
@load_lang.sql
lang is the specific language (for example, load_de.sql for German or load_ja.sql for Japanese).
4.4.7 About Managing JOB_QUEUE_PROCESSES
JOB_QUEUE_PROCESSES determine the maximum number of concurrently running jobs. In Oracle Application Express release 3.2, transactional support and SQL scripts require jobs. If JOB_QUEUE_PROCESSES is not enabled and working properly, you cannot successfully execute a script.
4.4.7.1 Viewing the Number of JOB_QUEUE_PROCESSES
JOB_QUEUE_PROCESSES:
4.4.7.1.1 Viewing JOB_QUEUE_PROCESSES in the Installation Log File
JOB_QUEUE_PROCESSES in the installation log files. See "Reviewing a Log of an Installation Session".
4.4.7.1.2 Viewing JOB_QUEUE_PROCESSES in Oracle Application Express
JOB_QUEUE_PROCESSES on the About Application Express page.JOB_QUEUE_PROCESSES displays at the bottom of the page.
4.4.7.2 Changing the Number of JOB_QUEUE_PROCESSES
JOB_QUEUE_PROCESSES by running a SQL statement in SQL*Plus:JOB_QUEUE_PROCESSES:SYS specifying the SYSDBA role:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
ALTER SYSTEM SET JOB_QUEUE_PROCESSES = <number>
ALTER SYSTEM SET JOB_QUEUE_PROCESSES = 20 sets JOB_QUEUE_PROCESSES to 20.
4.4.8 Configuring the SHARED_SERVERS Parameter
SHARED_SERVERS database initialization parameter is set to a reasonable value (that is, not 0 or 1). For a small group of concurrent users, Oracle recommends a value of 5 for SHARED_SERVERS.SYS specifying the SYSDBA role. For example:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
ALTER SYSTEM SET SHARED_SERVERS = 5 SCOPE=BOTH;
4.4.9 Create a Workspace and Add Oracle Application Express Users
4.4.9.1 Creating a Workspace Manually
ADMIN account and password created or reset during the installation process.
http://hostname:port/apex/apex_admin
hostname is the name of the system where Oracle XML DB HTTP server is installed.port is the port number assigned to Oracle XML DB HTTP server. In a default installation, this number is 8080.apex is the database access descriptor (DAD) defined in the configuration file.admin.
4.4.9.2 Creating Oracle Application Express Users
4.4.9.3 Logging in to Your Oracle Application Express Workspace
http://hostname:port/apex
hostname is the name of the system where Oracle XML DB HTTP server is installed.port is the port number assigned to Oracle XML DB HTTP server. In a default installation, this number is 8080.apex is the database access descriptor (DAD) defined in the configuration file.htmldb or something else. Verify your DAD with your Oracle Application Express administrator.

SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
apxchpwd.sql. For example:
@apxchpwd.sql
4.5.2.2 Unlock the APEX_PUBLIC_USER Database User
APEX_PUBLIC_USER must be an unlocked account. To unlock the account for database user APEX_PUBLIC_USER, execute the following steps:SYS. For example:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
ALTER USER APEX_PUBLIC_USER ACCOUNT UNLOCK
4.5.2.3 Change the Password for the APEX_PUBLIC_USER Database User
DAD file, you have to change the password for the database user APEX_PUBLIC_USER. Please use the following steps to change the password for the APEX_PUBLIC_USER database user:SYS. For example:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
SQL> PASSWORD APEX_PUBLIC_USER
Changing password for APEX_PUBLIC_USER
New password: password
Retype new password: password
4.5.2.3.1 About Password Expiration in Oracle Database 11g
PASSWORD_LIFE_TIME is set to 180. If you are using Oracle Database 11g with Oracle Application Express, this causes the password for APEX_PUBLIC_USER to expire in 180 days. As a result, your Oracle Application Express instance will become unusable until you change the password.PASSWORD_LIFE_TIME parameter is set to unlimited and alter the APEX_PUBLIC_USER account and assign it the new profile.
4.5.2.4 Copy the Images Directory
images directory from the top level of the apex\images directory to the location on the file system containing the Oracle home for Oracle HTTP Server.
4.5.2.4.1 Copying the Images Directory After an Upgrade
