You can name a transaction. This is useful for identifying a specific distributed transaction and replaces the use of the COMMIT COMMENT
statement for this purpose.
To name a transaction, use the SET TRANSACTION...NAME
statement. For example:
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE NAME 'update inventory checkpoint 0';
This example shows that the user started a new transaction with isolation level equal to SERIALIZABLE
and named it 'update inventory checkpoint 0'
.
For distributed transactions, the name is sent to participating sites when a transaction is committed. If a COMMIT COMMENT
exists, it is ignored when a transaction name exists.
The transaction name is displayed in the NAME
column of the V$TRANSACTION
view, and in the TRAN_COMMENT
field of the DBA_2PC_PENDING view when the transaction is committed.
