I blogged multiple times about DBMS_OPTIM_BUNDLE, the package to work with the Fix Control Persistence (FCP) framework in the database. And we also gave recommendations over the years that you need to test carefully when you are going to enable the fixes while patching. But it is a good practice do enable them when you do upgrade testing, and also when you start creating new databases in a new environment.

Yesterday, I delivered a full-day workshop for ora2know in Düsseldorf. And we discussed the most recent RUs as well, especially since "Database Patching" consumed a significant part of the day content-wise.
