Also could use "delete archivelogs backed up 5 times to device type disk".

 Are you not also putting the archive logs on tape?

I would assume you are and thus wonder why you can't restore said archive logs from tape if needed? (Along with the backups you would have to restore anyway in order to use them).

        Hi          

        We have standby databases and we don´t want to re-configure standbys if the WAN is going down during 2 days and the archivelogs was deleted.

        So we need to have more archivelogs on production server but can´t have 5 days of backups on disk because space constraints.          

        We have 9i and there is not configure archivelog deletion policy to applied on standby;

        We do backup everyday. First to disk and then copy it to tape.

	you can't do it automatically. Oracle considers RETENTION WINDOW and REDUNDANCY as mutually exclusive policies. You could handle it through tags, but I don't think that would be easy. Do you have a tape backup infrastructure? why do you need both five days and 2 backups? it doesn't make sense to me. How often do you run backup?

	Not sure if I understand correctly but cant you change the retention policy just before the deleting and changed it back afterwards?

	RMAN "delete noprompt force obsolete" delete backups and archivelogs.

	 

	Retention policy to redundancy 2;

	 

	I can´t use  

	DELETE BACKUP COMPLETED BEFORE 'SYSDATE-3' DEVICE TYPE DISK;

	DELETE ARCHIVELOG UNTIL TIME 'SYSDATE-7';

	because it´s time based and I need to have always 2 backup copies on disk.

	 

	Any way to do it?

	 

	Thks.
