Hi, I had a production DB on oracle 10g RAC with 2 instances. I had a problem, so I switched to another server with a single instance. Now I would return to the first configuration (DB RAC), it already exists and I would use RMAN backup pieces. Have you any idea or document for this operation of restore?
