PROBLEM:
While taking rman backup, it failed with below error ( ORA-19809 & ORA-19804)
RMAN> backup archivelog all; Starting backup at 26-MAY-17 current log archived using channel ORA_DISK_1 channel ORA_DISK_1: starting archived log backup set channel ORA_DISK_1: specifying archived log(s) in backup set input archived log thread=1 sequence=1942 RECID=1750 STAMP=944758808 input archived log thread=1 sequence=1943 RECID=1751 STAMP=944773254 channel ORA_DISK_1: starting piece 1 at 26-MAY-17 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03009: failure of backup command on ORA_DISK_1 channel at 05/26/2017 11:53:47 ORA-19809: limit exceeded for recovery files ---------------------------------------- > ERROR ORA-19804: cannot reclaim 882983936 bytes disk space from 5368709120 bytes limit -----------> ERROR
SOLUTION:
1. Check the value of db_recovery_file_dest_size:
SQL> show parameter db_recovery NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ db_recovery_file_dest string /archive/TESTDB db_recovery_file_dest_size big integer 5G
2. Check the space usage in recovery_dest
SQL> select SPACE_USED/1024/1024/1024 "SPACE_USED(GB)" ,SPACE_LIMIT/1024/1024/1024 "SPACE_LIMIT(GB)" from v$recovery_file_dest; SPACE_USED(GB) SPACE_LIMIT(GB) ---------- ----------- 4.5 5
We can see out of 5G, 4.5G is already used. Let’s increase the value of db_recovery_file_dest to a higher value.
3. Increase db_recovery_file_dest
SQL> alter system set db_recovery_file_dest_size=8G; System altered. SQL> select SPACE_USED/1024/1024/1024 "SPACE_USED(GB)" ,SPACE_LIMIT/1024/1024/1024 "SPACE_LIMIT(GB)" from v$recovery_file_dest; SPACE_USED(GB) SPACE_LIMIT(GB) -------------- --------------- 5.31985807 8
Run the rman job again, It will complete successfully.
