Hi Amir,

You need to load the plan manually using DBMS_SPM package.Identify the SQLID of the plan that you need. Manually loaded plans are automatically marked as accepted, so manual loading forces the evolving process.

When using SQL plan baseline, is it possible to instruct the optimizer to use a baseline that has sub-optimal plan than the one it is currently using. For example, a SQL statement, which cannot be altered because it is coming out of a COTS application, is currently using an index scan and I would like to force it to use FTS. I have tried forcing the optimizer to use the SQL plan baseline but it keeps using the index path and hence ignoring the plan baseline. Any feedback will be appreciated.
