RMAN reclaimable space

Hello all,

 

I'm making a RMAN backup to the FRA (on SAN) and later to tape (backup recovery area).

Looking at the space available is see:

SQL> SELECT * FROM V$FLASH_RECOVERY_AREA_USAGE;

FILE_TYPE    PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES
------------ ------------------ ------------------------- ---------------
CONTROLFILE                 ,08                         0               1
ONLINELOG                     0                         0               0
ARCHIVELOG                 2,58                      2,58              12
BACKUPPIECE                93,3                     62,03              37
IMAGECOPY                     0                         0               0
FLASHBACKLOG                  0                         0               0

In my opinion there a lot of reclaimable space available.

When I make a backup of a datafile:

RMAN> backup device type disk tag 'BACKUP_TWINDBT_WEE_011011120003' datafile '+TWINTGRP01/twindbt/datafile/ts_cwzmdb_i.ora';
