RMAN-03009: failure of backup command on ORA_DISK_1 channel at 08/27/2013 15:58:

ORA-19809: limit exceeded for recovery files
ORA-19804: cannot reclaim 52428800 bytes disk space from 4327473152 limit


When I went through some forums, I found a lot of solutions, but when I checked with their situations, it doesn't match.


One solution was to increase the db_recovery space. So I checked the space and got this result.


db_recovery size

 SQL> show parameter db_recovery;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest                string      /u01/app/oracle/fast_recovery_
                                                 area
db_recovery_file_dest_size           big integer 4127M



 Space Usage 


SQL> select SPACE_USED,SPACE_LIMIT from  v$recovery_file_dest;

SPACE_USED SPACE_LIMIT

 800155136  4327473152

 Available Space 


 SQL>SELECT

TO_CHAR(SPACE_LIMIT, '999,999,999,999') AS SPACE_LIMIT,
TO_CHAR(SPACE_LIMIT - SPACE_USED + SPACE_RECLAIMABLE,
'999,999,999,999') AS SPACE_AVAILABLE,
ROUND((SPACE_USED - SPACE_RECLAIMABLE)/SPACE_LIMIT * 100, 1)
AS PERCENT_FULL
FROM V$RECOVERY_FILE_DEST;

 From RMAN 


RMAN> show all;

CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2.0/db_1/dbs/snapcf_agge.f'; # default

What should I do to resolve this problem? Do I have to increase the recovery space even after I am having this much space? 

Using ORACLE 11G R2 in RHEL5
The db_recovery_file_dest includes a variety of files, including online AND archived redo log files; take a look at the Oracle Backup and Recovery User's Guide chapter 5 to find out the best solution; disabling db_recovery_file_dest is not a good idea.  You can try 

RMAN&gt; report obsolete;


RMAN command to see what can be deleted. Then do a delete obsolete to delete them. Do you have any guaranteed restore points defined? 

RMAN&gt; list restore point all;


If you see any results with type GUARANTEED, if they are no longer needed, remove them:

SQL&gt; DROP RESTORE POINT before_app_upgrade;


Is flashback database enabled?
