So here's the situation we're in: We lost the machine that has the RMAN catalog database on it and we need to restore one of our backups. I have all the files that RMAN makes when it backs up a database and the archivelogs that go with that backup. The issue is I cannot find anything in the RMAN documentation that tells me how to restore a backup with a missing catalog. Am I missing something simple or am I hosed?
I do believe you are correct. A limited number of backups info is keep in the control file. The second issue that I failed to articulate is that the database we need to restore resides on the same machine we lost. So all I have is the backed up copy that RMAN makes. There doesn't seem to be an intuative way to discern where RMAN put the control file or how to access it.
