mine is 8.1.6 on hpux 11.0
i've got stuck with rollback segment problem
i offlined a rbs but couldn't drop it because of pending trans.
but the dropping failed even when there were no
users or trans on the system.
v$rollstat says it's pending offline with xact as 1.
dba_rollback_segs say it's online.
v$transaction has nothing against that rbs.
now iam even not able to drop the rbs tablespace
because of error "rbs with active rollback segment exist"
and unfortunately this rbs has 1300 extents of 3m each allocated to it and tied up in datafile.
