Oracle RMAN backup related information query

Query the RMAN backup status mainly through the view V$RMAN_STATUS, this view can query the operations performed by RMAN.
We mainly look at two columns: OPERATION and STATUS.

The values of OPERATION are: RMAN, BACKUP, DELETE, CROSSCHECK, DELETE OBSOLETE, etc.

The values of STATUS are: RUNNING, FAILED, COMPLETED, COMPLETED WITH ERRORS, COMPLETED WITH WARNINGS, etc.

If you want to view the output of RMAN, you can view V$RMAN_OUTPUT. This view records the information generated by RMAN, which is an in-memory view and will not be recorded to the control file. There are at most 37278 records.

If you want to view more detailed information about RMAN backup, you can view V$RMAN_BACKUP_JOB_DETAILS.

View backup failure records:

SELECT * FROM V$RMAN_STATUS

WHERE START_TIME >= TO_DATE(&START_TIME,'YYYY-MM-DD HH24:MI:SS')

  AND END_TIME   <= TO_DATE(&END_TIME  ,'YYYY-MM-DD HH24:MI:SS')

  AND OPERATION ='BACKUP'

  AND STATUS !='COMPLETED'

  AND STATUS NOT LIKE 'RUNNING%';

View the record of successful backup:

SELECT * FROM V$RMAN_STATUS
 
WHERE START_TIME >= TO_DATE(&START_TIME,'YYYY-MM-DD HH24:MI:SS')
 
  AND END_TIME   <= TO_DATE(&END_TIME  ,'YYYY-MM-DD HH24:MI:SS')
 
  AND OPERATION ='BACKUP'
 
  AND STATUS ='COMPLETED';

FROM V$BACKUP_DATAFILE C, V$BACKUP_PIECE A, V$DATAFILE D

WHERE A.SET_STAMP = C.SET_STAMP

    AND D.FILE# = C.FILE#

    AND A.DELETED='NO'

    AND c.set_stamp=&set_stamp

 ORDER BY C.FILE#;
