Monitor RMAN Restore

Here are some queries you can check and play while waiting for an RMAN restore to complete.

These queries are useful to monitor the restore, tracks progress (percentage completed and throughput), and identify potential problems.

TTITLE LEFT '% Completed. Aggregate is the overall progress:'
SET LINE 132
SELECT opname, round(sofar/totalwork*100) "% Complete"
  FROM gv$session_longops
 WHERE opname LIKE 'RMAN%'
   AND totalwork != 0
   AND sofar <> totalwork
 ORDER BY 1;

TTITLE LEFT 'Channels waiting:'
COL client_info FORMAT A15 TRUNC
COL event FORMAT A20 TRUNC
COL state FORMAT A7
COL wait FORMAT 999.90 HEAD "Min waiting"
SELECT s.sid, p.spid, s.client_info, status, event, state, seconds_in_wait/60 wait
  FROM gv$process p, gv$session s
 WHERE p.addr = s.paddr
   AND client_info LIKE 'rman%';

TTITLE LEFT 'Files currently being written to:'
COL filename FORMAT a50
SELECT filename, bytes, io_count
  FROM v$backup_async_io
  WHERE status='IN PROGRESS'
/

       ROUND(SUM(v.value/1024/1024),1) || ' Meg so far @ ' ||
       ROUND(SUM(v.value     /1024/1024)/NVL((SELECT MIN(elapsed_seconds)
            FROM v$session_longops
            WHERE opname          LIKE 'RMAN: aggregate input'
              AND sofar           != TOTALWORK
              AND elapsed_seconds IS NOT NULL
       ),SUM(v.value     /1024/1024)),2) || ' Meg/sec'
