    I have OPS. aix 4.3
    I wnat to restore from cluster A to B. I have the backup of A. But no archivelogs.
    Now I have restore to B. But it won't open irrespectively of the option I use. It call for use of backup contofile MUST BE DONE. But when you do that it calls for some checkpoint or log to be applied. The problem is I want to assume that all these achive logs are missing and thus open with resetlogs. I have used (set until scn 1635063555 this is the latest checkpoit in the controlfile that was backed up. I have even gone to earlier SCNs. In desperation I have decided to set time to 1 then 2 days earlier that the day of backup (rremmber this is whole database backup). Does this mean you cannot open a database without applying a log? This is somewhat fussy to me because if I took a bckup on jan 04 (online) it follows that all SCNS which were generated on jan 03:00:00 should be in the controlfile by now. Then i can be able to recover to say 03:23:59 and open with resetlogs 'b/c I don't have the archives'. Thsi this has been impossible. Below is an except of problem encountered.

    Even when you do an incomplete recovery, you need to apply at least one archive log after restoring your datafile(s). This would be the archive log containing the end-of-backup marker. Without that, you can't get the database into a consistent state.

    To do the restore and recovery, you need to be connected to the RMAN. In your case, looks like your are trying to do things through the server manager.

    Yea, because RMAN does not understand USING BACKUP CONTROLFILE.
