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.

         

        Dick:

        We have older backups on tape so we can use and old backup and apply 
archivelogs to made point in time recovery.

         

        Thanks

        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

        I need to have 2 backups and 5 days of archivelogs on disk.

         

        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.
