Home -> Community -> Mailing Lists -> Oracle-L -> RE: Analyzing a Trigger for Performance
Hi Hannah,
Have you looked into the DBMS_PROFILER and DBMS_TRACE packages? They can be used to trace PL/SQL execution and performance.

Hi,
I had noticed that one of our triggers is performing very badly. I had disabled the trigger to test replication and there was a issue with the trigger. When the developer changed the trigger and enabled it, replication slowed down to one record per second (other tables are being updated, instered, and deleted from).
I analyzed the plans for all sql statements generated in the trigger itself and they are all using the correct indices etc. There are no full table scans etc. We have simliar trigger on our other replicated tables that are not seeing THIS bad performance.
Any one have any suggestions/links for putting this trigger through the paces to determine the bottleneck?
Thanks,
Hannah
