Using automatic SQL tuning and SQL Profiles for fast ETL performance troubleshooting

In the previous post we have showed how we can use SQL Profiles and a script that we can download from Metalink in order to fix the execution plan of a query to a specific one that we have found from the available plans in AWR (or Library Cache) that has a better elapsed.

In this post, we will continue our discussion on SQL Profiles and show another way that we can exploit them in order to very fast troubleshoot SQL tuning issues, without the need to write code, deploy new code into production etc.
