I have an issue. Let me explain the scenario — before configuring NetBackup, my RMAN backups and deletion commands worked properly. However, after configuring NetBackup, the backups are running successfully, but when I perform the delete command, I’m getting the error: “no channel allocated for maintenance (of an appropriate type).”
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of delete command at 08/03/2025 23:38:29
RMAN-06091: no channel allocated for maintenance (of an appropriate type)
Additionally, I have set up a cron job for RMAN backups that performs a level 0 backup on Sundays and a level 1 backup on the other days. The RMAN retention policy is set to a recovery window of 2 days, but I’ve noticed that the full backup is getting deleted immediately after the new full backup is taken. This issue occurs after the NetBackups configuration.
My Questions
- Will the DELETE command not perform on both disk and tape, or only on tape?
- Will the retention policy apply to both disk and tape backups?
- What could be the exact reason for backups being deleted without following the retention policy?
- If RMAN can delete the backup sets, then why doesn’t it delete the control file snapshot?
Can Anyone help me out?
Thanks in Advance.
