How to make sure SQL Profile is correctly implemented

edited May 21, 2020 9:38AM in SQL Performance (MOSC) 4 commentsAnswered ✓

Using Enterprise Manager 13c, I ran the SQL Tuning Advisor on a particular query because of performance concerns and I was given several recommendations, which was good. Even though one of the recommendations gave a better perceived improvement - it involved parallel execution - I do not want to accept this option but instead apply the SQL Profile that it recommends. Easy enough, I thought.

However, when I absolutely make sure I select the type and then the SQL Profile radio buttons, which is the second option, it always implements the parallel execution option, which I do not want. I have disabled/deleted the resulting profile many times after repeating this again and again to make sure I'm selecting what I want but the "normal" SQL Profile is never implemented.

Howdy, Stranger!
