RE: changing optimizer_mode for a running session

I am talking of a scenario where another user has already connected to the database and is running a report.
I can use dbms_system.set_ev to get a 10046 trace online [the "running session"] but can't change it's optimizer_mode.
I do not want to have to stop the session, change and restart it --- it could be a report to modify which could take a few weeks in the approval cycle or it could be coming from an application server / JSP which has generated it's own SQL.
Changing optimizer_mode globally at the ALTER SYSTEM level isn't what I am looking for either. Hemant
