Last time I had to do this was before automatic UNDO, so I'm not sure it will still work. 1) create a new (it can be modest) undo tablespace 2) shutdown, point the parameter at the new undo tablespace 3) startup mount, alter the datafiles and previous undo tablespace's files off line 4) bring the tablespaces containing the not rolled back objects back on line. 5) If you get that far, drop the not rolled back objects. 6) 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. mwf _____ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Brian S Wisniewski Sent: Thursday, April 02, 2009 12:30 PM To: oracle-l@xxxxxxxxxxxxx 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.
