Autonomous transactions are started by a parent, or main,
transaction but operate
independently of the parent for transaction control. If a
commit or rollback is used
in the autonomous or main transaction, or if a failure
occurs for any reason, it does
not impact the other transaction.
Our favorite use of this feature is for logging application
events. If the need is to
log activity, regardless of the outcome, but the logging
success or failure should not
impact the application, autonomous transactions are the
perfect solution.
To create an autonomous transaction, use a pragma called
AUTONOMOUS_TRANSACTION. The pragma is placed in the
declaration section of the block.
