 Solution:

We should delete the obsolete backups as follows.

 

If you are using the Tape backup, then run the following commands.


RMAN> allocate channel for maintenance device type 'sbt_tape' PARMS 'ENV=(NSR_SERVER=, NSR_CLIENT=)';

RMAN> delete obsolete;

RMAN> crosscheck archivelog all;

RMAN> delete archivelog all backed up 2 times to sbt_tape;

RMAN> crosscheck archivelog all;

 

If you are using the Disk backup, then run the following commands.

RMAN> allocate channel for maintenance device type disk;

RMAN> delete obsolete device type disk;

RMAN> crosscheck archivelog all;

RMAN> delete archivelog all backed up 2 times to disk;

RMAN> crosscheck archivelog all;
