Key Parameter Renaming for Auto Transaction Rollback Feature in 23ai

Posted by FatDBA on July 14, 2024

Hi Everyone,

With Oracle 23ai, the ‘auto transaction rollback‘ feature has undergone some parameter renaming. For more details on this feature, please refer to my previous blog post – Link

The parameter “TXN_AUTO_ROLLBACK_HIGH_PRIORITY_WAIT_TARGET”, which specifies the maximum number of seconds a HIGH priority transaction will wait for a row lock before the Priority Transactions feature rolls back a lower priority transaction holding the lock, is now renamed to “PRIORITY_TXNS_HIGH_WAIT_TARGET“.

Similarly, “TXN_AUTO_ROLLBACK_MEDIUM_PRIORITY_WAIT_TARGET“, which specifies the maximum number of seconds a MEDIUM priority transaction will wait for a row lock before the Priority Transactions feature rolls back a lower priority transaction holding the lock, is now renamed to “PRIORITY_TXNS_MEDIUM_WAIT_TARGET“.

Finally, “TXN_AUTO_ROLLBACK_MODE“, which specifies the mode for Priority Transactions (ROLLBACK or TRACK), is now renamed to “PRIORITY_TXNS_MODE“.

Hope It Helped.
