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.

                    ORACLE-L

Oracle 8.1.6.3 on Sun Solaris 2.6.

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?

TIA Terry
