Plese check below MOS doc.
A Complete Understanding of RMAN Compression [ID 563427.1]
check this and compare with your compression....
1. There is seede RMAN forum site
2. If you change below parameter than you start to advance compress which you need to pay extra license
3. You need to change below parameter:
CONFIGURE COMPRESSION ALGORITHM 'MEDIUM' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE;
4. Please review:
I changed from BASIC to MEDIUM. but, still the beckupsets are not compressing.
I have changed in backup script too like
# recommended format
AS COMPRESSED BACKUPSET DATABASE;
and RMAN configuration is
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO COMPRESSED BACKUPSET;
CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE;
now the backup sets compressing.
Thanks all to responding my query.
