Then have two sets of packages for reports, when releasing new versions, do them on set 2 whilst normal users are running on set 1. This gives you time to test new versions in production as well. When tests are successful, switch to set 2.

Oh yes, this requires your application/reports to be aware of this "set" architecture. Basically you should have some kind of control table where you state on which set newly executed reports should run.

Btw, how can you have constant DML activity and reporting going on when you have suspended your sessions?
When your session executes a package and is suspended, the package is still pinned anyway and you cant just replace it on the fly.

The baseline is, despite RAC you still one single database and you can't have this kind of online updating without doing some fundamental changes in the app.

(basically this app runs ESPN daily business). There is constant DML and reporting activity on the database.
