Then consider changing RMAN ARCHIVELOG DELETION POLICY.Back up files to tertiary device such as tape using RMAN

BACKUP RECOVERY AREA command.Add disk space and increase db_recovery_file_dest_size parameter to

Reflect the new space.Delete unnecessary files using RMAN DELETE command. If an operating

System command was used to delete files, then use RMAN CROSSCHECK and
