This chapter describes the commands and associated syntax of the Oracle Connection Manager Control utility.
This chapter contains the following topics:
The Oracle Connection Manager Control utility enables you to administer Oracle Connection Managers. You can use its commands to perform basic management functions on one or more Oracle Connection Managers. Additionally, you can view and change parameter settings.
The basic syntax of the Oracle Connection Manager Control utility is as follows:
cmctl command [argument]
You can use Oracle Connection Manager Control utility in command mode, or batch mode.
Using the command mode:
From the Oracle Connection Manager Control utility:
Enter cmctl at the command line to obtain the program prompt; then issue the command:
cmctl
CMCTL> command
From the operating system:
Enter the entire command from the operating system command prompt:
cmctl [command] [argument1 . . . argumentN] [-c instance_name]
Each command issued in this way can have the name of an Oracle Connection Manager appended as an argument. If an Oracle Connection Manager instance name is not provided, then the default instance name is assumed. The default name is cman_hostname. You may be prompted for a password if one was set in a previous CMCTL session. Issuing commands from an Oracle Connection Manager Control utility session of Oracle Connection Manager requires that a password be entered once, at the beginning of the session, if one has been set.
Caution:
There is an option to specify the password on the command line. However, this exposes the password on the screen, and is a potential security risk. Oracle recommends not using the password option (-p) on the command line.See Also:
Oracle Database Net Services Administrator's Guide for an overview of the Oracle Connection Manager processesUsing the batch mode:
You can combine commands in a standard text file and then run them as a sequence of commands. To run in batch mode, use the following syntax:
cmctl @input_file
The Oracle Connection Manager Control utility supports four types of commands:
Initialization and termination commands such as STARTUP and SHUTDOWN
Alter commands such as SET LOG_LEVEL and SET EVENT
Display commands, such as SHOW STATUS and SHOW RULES
Gateway commands such as SHOW GATEWAYS and RESUME GATEWAYS
Note:
You can use SET commands to dynamically alter configuration parameters, the changes only remain in effect until the Oracle Connection Manager is shut down. You cannot save them to thecman.ora file. The one exception is the Oracle Connection Manager password, which you can save using the command SAVE_PASSWD.This section lists and describes the following commands for the Oracle Connection Manager Control utility:
To select an Oracle Connection Manager instance.
None
From the Oracle Connection Manager Control utility:
CMCTL> ADMINISTER [-c] instance_name
instance_name: The instance of Oracle Connection Manager that you would like to administer. Instances are defined in the cman.ora file.
You can issue the ADMINISTER command only within the utility. You cannot issue the command from the operating system.
ADMINISTER enables you to choose an Oracle Connection Manager to administer. To start this Oracle Connection Manager, you must issue STARTUP.
When you omit the instance name from the command, the instance administered defaults to the local instance.
Use the -c option when you want to administer an instance that is not the local instance.
A password is required only if one was provided at installation time or during a previous session of the Oracle Connection Manager.
CMCTL> ADMINISTER cman_indl040ad
Enter CMAN password: password
Current instance cman_indl040ad is already started
Connections refer to (address=(protocol=TCP)(host=indl040ad)(port=1560)).
The command completed successfully
To terminate connections, using specific qualifiers to select connections.
Oracle Connection Manager must be running.
From the operating system:
cmctl CLOSE CONNECTIONS [in state] [gt time] [from source] [to destination] [for service] [using gateway_process_id] [connect_identifier_list] [-c cman_name]
From the Oracle Connection Manager Control utility:
CMCTL> CLOSE CONNECTIONS [in state] [gt time] [from source] [to destination] [for service] [using gateway_process_id] [connect_identifier_list]
state: One of the following values to specify the connection state:
idle: Connections that are inactive in the established state
connecting: Connections that are in the process of connecting
established: Connections that are connected and are transferring data
terminating: Connections that are disconnecting
If no state is specified, then CLOSE CONNECTIONS defaults to all possible states. If the time qualifier is included under these conditions, then the time specified is the amount of time that has elapsed since a client initiated a connection.
time: The time format. Use the following format to specify connections greater than the time indicated:
gt[hh:mm:]ss
source: The source address. Use one of the following formats to specify the source address:
from IP
from hostname
from subnet
destination: The destination address. Use one of the following formats to specify the destination address:
to IP
to hostname
to subnet
service: The service name. Use the service_name parameter to specify the service, such as sales.us.example.com.
gateway_process_id: The gateway process identifier is a number. Use this number to specify connections that are proxied by the gateway process indicated. To determine the gateway process identifier, use the Oracle Connection Manager control utility show gateways command.
connect_identifier_list: The connection identifiers. Use a space between multiple connection identifiers in a list.
Because the CLOSE CONNECTIONS command terminates connections, it might generate error messages on both client and server sides.
The IDLE state qualifier always requires a time qualifier.
Issuing CLOSE CONNECTIONS without an argument closes all connections.
The following example shuts down connections in any state. The elapsed time of the connection must be greater than 1 hour and 30 minutes. The connection source is the specified subnet, and the destination is the specified host name.
CMCTL> CLOSE CONNECTIONS gt 1:30:00 from 192.168.2.32/27 to host1
The following example shuts down those connections proxied by gateway process 0 that have been in the idle state more than 30 minutes:
CMCTL> CLOSE idle CONNECTIONS gt 30:00 using 0
The following example shuts down connections that are connected to the service sales.us.example.com:
CMCTL> CLOSE established CONNECTIONS for sales.us.example.com
To exit from the Oracle Connection Manager Control utility.
