(Apps Server running AS Infra & BI).
I have been asked to restore an application server that was had Infra & BI installed & running. I have a server backup tape that I can recover everything from except for the repository files (datafiles, controlfiles etc); for some reason the repository's directories were excluded form the server backups, and the repository was not backed up using RMan. So basically, I have an Apps server with a black hole where the repository should be.

Is it possible to create a new repository only & point the Infra & BI to it? Or will I have to start from afresh, rebuilding the whole server?

Thanks in advance for any help/suggetsions.
