RMAN Queries

In this post, I’ve shared a set of RMAN-related SQL queries that help you quickly check backup details, identify issues, and verify restore sessions— directly from the database views.

1. Find RMAN Complete Percentage


set linesize 110
set pagesize 300
SELECT sid, serial#, context, sofar, totalwork , opname,
round(sofar/totalwork*100,2) "Complete"
FROM v$session_longops
WHERE opname LIKE 'RMAN%' and totalwork<>0 and round(sofar/totalwork*100,2)<>100;

--More Details
col dbsize_mbytes      for 99,999,990.00 justify right head "DBSIZE_MB"
col input_mbytes       for 99,999,990.00 justify right head "READ_MB"
col output_mbytes      for 99,999,990.00 justify right head "WRITTEN_MB"
col output_device_type for a10           justify left head "DEVICE"
col complete           for 990.00        justify right head "COMPLETE %" 
col compression        for 990.00        justify right head "COMPRESS|% ORIG"
col est_complete       for a20           head "ESTIMATED COMPLETION"
col recid              for 9999999       head "ID"

select recid
     , output_device_type
     , dbsize_mbytes
     , input_bytes/1024/1024 input_mbytes
     , output_bytes/1024/1024 output_mbytes
     , (output_bytes/input_bytes*100) compression
     , (mbytes_processed/dbsize_mbytes*100) complete
     , to_char(start_time + (sysdate-start_time)/(mbytes_processed/dbsize_mbytes),'DD-MON-YYYY HH24:MI:SS') est_complete
  from v$rman_status rs
     , (select sum(bytes)/1024/1024 dbsize_mbytes from v$datafile) 
 where status='RUNNING'
   and output_device_type is not null
/

2. Find RMAN session in Database


select b.sid, b.serial#, a.spid, b.client_info
from v$process a, v$session b
where a.addr=b.paddr and client_info like 'rman%';

3. Kill RMAN Sessions:


alter system kill session 'SID,SERIAL#' immediate;
alter system kill session 'SID,SERIAL#,@<Instance_id>' immediate;  -- In RAC

4. RMAN Restore Monitor:


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;


5. RMAN Backup Details with Size:


set pages 2000 lines 200
COL STATUS FORMAT a9
COL hrs FORMAT 999.99
select INPUT_TYPE,
STATUS,
TO_CHAR(START_TIME,'mm/dd/yy hh24:mi') start_time,
TO_CHAR(END_TIME,'mm/dd/yy hh24:mi') end_time,
ELAPSED_SECONDS/3600 hrs,
INPUT_BYTES/1024/1024/1024 SUM_BYTES_BACKED_IN_GB,
OUTPUT_BYTES/1024/1024/1024 SUM_BACKUP_PIECES_IN_GB,
OUTPUT_DEVICE_TYPE
FROM V$RMAN_BACKUP_JOB_DETAILS
order by SESSION_KEY;

6. History of RMAN Backup Details:


select
  to_char(j.start_time, 'yyyy-mm-dd hh24:mi:ss') start_time,
  to_char(j.end_time, 'yyyy-mm-dd hh24:mi:ss') end_time,
  (j.output_bytes/1024/1024/1024) output_Gbytes, j.status, j.input_type,
  decode(to_char(j.start_time, 'd'), 1, 'Sunday', 2, 'Monday',
                                     3, 'Tuesday', 4, 'Wednesday',
                                     5, 'Thursday', 6, 'Friday',
                                     7, 'Saturday') dow,
  j.elapsed_seconds, j.time_taken_display,
  x.cf, x.df, x.i0, x.i1, x.l,
  ro.inst_id output_instance
from v$RMAN_BACKUP_JOB_DETAILS j
  left outer join (select
                     d.session_recid, d.session_stamp,
                     sum(case when d.controlfile_included = 'YES' then d.pieces else 0 end) CF,
                     sum(case when d.controlfile_included = 'NO'
                               and d.backup_type||d.incremental_level = 'D' then d.pieces else 0 end) DF,
                     sum(case when d.backup_type||d.incremental_level = 'D0' then d.pieces else 0 end) I0,
                     sum(case when d.backup_type||d.incremental_level = 'I1' then d.pieces else 0 end) I1,
                     sum(case when d.backup_type = 'L' then d.pieces else 0 end) L
                   from
                     v$BACKUP_SET_DETAILS d
                     join v$BACKUP_SET s on s.set_stamp = d.set_stamp and s.set_count = d.set_count
                   where s.input_file_scan_only = 'NO'
                   group by d.session_recid, d.session_stamp) x
    on x.session_recid = j.session_recid and x.session_stamp = j.session_stamp
  left outer join (select o.session_recid, o.session_stamp, min(inst_id) inst_id
                   from Gv$RMAN_OUTPUT o
                   group by o.session_recid, o.session_stamp)
    ro on ro.session_recid = j.session_recid and ro.session_stamp = j.session_stamp
where j.start_time > trunc(sysdate)-&NUMBER_OF_DAYS
order by j.start_time desc
