Should SQL Plan Baselines be used for Oracle 11g performance?

edited Jul 1, 2015 10:00AM in Siebel Business Process & Functionality (MOSC) 1 commentAnswered

We have some tables like S_USER, S_PARTY, S_PERSON whose statistics sometimes become stale. Oracle will parse and select a bad plan that brings our Application to it's knees. SQL Plan baselines in 11g were added as a replacement for SQL outlines to keep bad plans from creeping in. (https://docs.oracle.com/database/121/TGSQL/tgsql_spm.htm#TGSQL94621)

This is not addressed in the oft-referenced "Performance Tuning Guidelines for Siebel CRM Applications on Oracle Database".

Thank you
