I have never queried USER_ERRORS directly. I just type SHOW ERRORS in SQL*Plus. To do some source code analysis, it looks like I might check out USER_DEPENDENCIES, USER_ARGUMENTS, or USER_IDENTIFIERS. Looks like I got some homework to do. If I find anything of use, I will definitely share it.
I had heard about the V$SESSTAT view before. But I had not used it before and did not even know how to use it. This important view will help you determine what resources are being used. Yessir good stuff. You should really check out the Artical in the Nov/Dev 2012 Oracle magazine. Perhaps it is online somewhere. The title was "Beginning Performance Tuning: Diagnose the Past". Good luck peeps.
