Again ... dude ... try to figure out how to do this in sqlplus first please.

Each time I take an rman backup ( and I do disk backups not tape ... I get a tape backup later from the disk copies ) I also get a separate disk based backup of the control file. This control file "belongs to" that backup.

You have to restore that older copy of the control file first ... so that the restore will use the backup that belongs to that copy of the control file.

There is no substitute for taking the time to learn everything about backups and recoveries. Please take the time to become a professional in this area. Received on Mon Sep 20 2010 - 20:53:02 CDT
