Hi,
> 1. i want to delete all the archive logs after backed up to TAPE.?
And what is the question here? You are already using the RMAN clause "ARCHIVELOG ALL DELETE INPUT".
> 2. Also is it possible to delete old backup from tape before taking NEW backup so that i can free some space from TAPE for NEW ONE.?
Yes, if you would use a RMAN policy driven third party software like IBM Tivoli Data Protection for Databases. NetBackup is based on the NetBackup catalog driven retention policies and so you don't need to think about it - your NetBackup admin has to care about it. You only have to crosscheck the RMAN backups (and delete the expired ones) to keep the RMAN catalog up-to-date. By the way it makes *NO* sense to delete the old backup BEFORE taking a new backup.

Are you serious?
