Is there any way that we can change the optimizer_mode for a running session ? [Oracle 8.1.7]
The session may have started with the instance-level optimizer_mode=RULE [Oracle Apps R11.0] but I want to change the optimizer_mode for subsequent SQLs executed by the session, without killing and restarting the session -- something like using DBMS_SYSTEM.SET_EV to set an event in a running session.
