How to Tune SQL when You Can't Edit the Source Code, Part 2 of 2
 
01:46
How do you tune SQL if you don't have access to the source code? Sometimes. Oracle indexes, statistics, stored outlines, profiles or 12c directives will solve a tuning problem. However, as a last resort, you may want to add a hint. In this case (and you cannot edit the code) DBMS_ADVANCED_REWRITE could be the solution. In Part 2 of this tutorial, Oracle Certified Master DBA John Watson of SkillBuilders completes the demonstration - using DBMS_ADVANCED_REWRITE to change the SQL Oracle executes - without changing the source code!
