Hi,

Value of "db_recovery_file_dest_size" is 3T and actual space usage is 2.4T(seen from os, more space usage is for backups), but v$recovery_file_dest don't show actual space usage:

Select * from v$recovery_file_dest

F:\FRA	3298534883328	725639152120	133098700	1499	0

Select * from v$flash_recovery_area_usage

CONTROL FILE	0	0	1	0
REDO LOG	0	0	0	0
ARCHIVED LOG	1.19	0	1458	0
BACKUP PIECE	1.01	0	40	0
IMAGE COPY	0	0	0	0
FLASHBACK LOG	0	0	0	0
FOREIGN ARCHIVED LOG	0	0	0	0
AUXILIARY DATAFILE COPY	0	0	0	0

Note:I have run CrossCheck command in rman for updating rman repository(controlfile).

crosscheck backupset;
crosscheck backup;
crosscheck archivelog;

Could anyone explain whats is the reason?

Thanks in advance.

One common reason is that the FRA is full of stuf that the database has "forgotten" about, because you have set your control_file_record_keepp_time too low. Check this by running CATALOG START WITH....

Alternatively, you may have put files in the FRA directory manually.

Thank you for your reply,

Yes, You are right, This is the backup command:

run {
allocate channel oem_backup_ch1 type disk ;allocate channel oem_backup_ch2 type disk BACKUP FORMAT 'F:\FRA\ORCL\BACKUPSET\2017_03_14\DB_%d_D_%T_%u_s%s_p%p.BKP' TAG 'DB_Backup' keep until time 'sysdate+60'  DATABASE;RELEASE CHANNEL oem_backup_ch1;RELEASE CHANNEL oem_backup_ch2;
 }

do you mean that our mistake is that when we specified backup path(a path to FRA) in command?(FORMAT 'F:\FRA\ORCL\BACKUPSET\2017_03_14\DB_%d_D_%T_%u_s%s_p%p.BKP')

Is there anyway for updating rman repository and FRA?

Exactly. The FRA is just a bookkeeping mechanism. If you put stuff in an FRA directory without using FRA methods, that usage does not get recorded as such.
