Last time I had to do this was before automatic UNDO, so I'm not sure it will still work.
- create a new (it can be modest) undo tablespace
- shutdown, point the parameter at the new undo tablespace
- startup mount, alter the datafiles and previous undo tablespace's files off line
- bring the tablespaces containing the not rolled back objects back on line.
- If you get that far, drop the not rolled back objects.
- Bring the old undo back on line.
Possibly some old parameters like _offline_rollback_segments or _corrupt_rollback_segments were required, but I thought we had agreed that the object locks for undo would surrender to drop (breakable locks), anyway. Maybe that only works out cleanly when a single table is involved with the transaction being rolled back. And they certainly might have changed their minds.

Subject: Terminate rollback?
10.2.0.4 DEVELOPMENT database
Is there any way (oracle events) to stop a rollback that is in-flight? I want to drop the object that the rollback is occurring against and start over. The rollback that is in-flight is going to run for hours and I'd rather not wait, if possible. This is against a development database so I'm not concerned about using undocumented processes if anyone has one available. I looked through the oracle events but didn't find one that stood out.
Thanks - Brian
