Question about the difference between Auto SQL Tuning and SQL Baselines

edited May 23, 2013 3:42AM in SQL Performance (MOSC) 4 commentsAnswered ✓
I am trying to improve my understanding of how Auto SQL Tuning and SQL Plan Management work together. 

 

In an Oracle White Paper, SQL Plan Management in Oracle Database 11g (Nov 2010) , a section called "Integration with Automatic SQL Tuning” states that when SQL PROFILES are collected automatically and accepted the profiles are  added to the SQL Plan Baseline. In another white paper; SQL Profiles: Technical Overview (May 2010), I read that SQL Profiles are different from Baseline Plans because SQL Profiles don’t have to use the same execution plan as is required for SQL Baselines.

 

 

SQL Profiles can improve performance by recommending a different execution plan.

Howdy, Stranger!
