This way we get synchronized with the VM snapshot created at Storage level (meaning, directly using ZFS filesystem commands or from the OS of dedicated storage boxes) delete noprompt archivelog until time sysdate - 3; delete noprompt backup completed before sysdate-40/24; release channel d1; release channel d2; } RMAN delete backupset tagTAG20181024T085438; Method 3: You can also delete backupset those backed up before a particular time:
delete completed before TO_DATE(Date String,MM/DD/YYYY HH24:MI:SS);
For example: delete backup completed before TO_DATE(09/23/2018 08:00:00,MM/DD/YYYY HH24:MI:SS); And also, if backupset file is deleted by OS command, then you can delete related information via RMAN by using force. eg: RMAN delete force backupset 1; RMAN delete force backupset tagTAG20181024T085438; RMAN delete force noprompt backup completed before TO_DATE(09/23/2018 08:00:00,MM/DD/YYYY HH24:MI:SS);
