FROM   V$SESSION_LONGOPS
WHERE  OPNAME LIKE 'RMAN%'
--AND    PNAME NOT LIKE '%aggregate%'
AND    TOTALWORK != 0
AND    SOFAR <> TOTALWORK;


select sl.sid, sl.opname,
       to_char(100*(sofar/totalwork), '990.9')||'%' pct_done,
       sysdate+(TIME_REMAINING/60/60/24) done_by
  from v$session_longops sl, v$session s
 where sl.sid = s.sid
   and sl.serial# = s.serial#
   and sl.sid in (select sid from v$session where module like 'backup%' or module like 'restore%' or module like 'rman%')
   and sofar != totalwork
        and totalwork > 0
