Hi, RMAN reports latest backup pieces as expired, I have configured the retention policy as follows:

RMAN>configure retention policy to recovery window of 30 days.

I take weekly full backup of database including archivelogs using rman. On month end I delete the archive logs from rman by giving the command to remove the previous one month old archivelogs from the disk.

RMAN>delete archivelog until time 'sysdate-30';

Kind help is highly appreciated,
