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.
Thanks

Subject: Enforcing plan via SQL plan baseline
Folks,
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.
Thanks
Amir
