The rollback segment will not shrink if there are active transactions in the rollback segment i.e xacts >0 in v$rollstat for that rollback segment. Check out which transaction is using the rollback segments using v$transaction where XIDUSN = usn from v$rollname. The ses_addr in v$transaction should point you to the session which is running this transaction. Do the honours for that session.

The rollback tablespace filled up last night and the rollback segments became full. I added space to the tablespace and tried shrinking the rollback segments. They remained full, so I altered them offline and online. The extents are increasing, but I still can not get a shrink to work. If they don't stop increasing, my tablespace will fill up again and I can't keep throwing disk at it. Since this is a production system, bouncing is not an option. Any ideas?
