Stabilizing Performance when Upgrading an Oracle Database – A Free Tutorial

SQL Plan Baselines Are Your Friend

Recommended Prerequisite: Free Tutorial: How to Read an Execution Plan

Learn how to use sql plan baselining to maintain consistent performance when upgrading an Oracle Database.

We all know what happens with performance when you upgrade: 90% of your SQLs run the same, 9% run better, and for 1% performance drops through the floor. And if you are unlucky, it is the 1% that matter.

The solution is Baselining. Baselines stabilize your execution plans through the change, letting you upgrade safely. The basic functionality is now available for SE2 as well as EE.

Oracle Certified Master DBA John Watson will demonstrate identifying a problem caused by an upgrade from 11g to 19c, capturing a baseline on 11g, transferring the baseline to 19c, and showing that the 11g plan is carried through and performance returns to normal.
