Brian - My sys admin pleads amnesia on the NFS problem. My recollection was that it was misconfigured or had a default configuration that expected only a couple of connections and RMAN actually opens MANY file connections. My specific symptoms is that RMAN would create the first few data files and then just stop. Oracle Support made me take NFS out of the mix and then everything worked.

In your case, I am also concerned about the control file. I was unable to get 8i to create the control file from the backup although others on this list reported success with that. I would feel better if you said that you separately backed up the control file at the end of the RMAN backup, and manually moved that control file into place on the test system. At least you would eliminate that as the problem.

DENNIS...Thanks for your feedback. Here it is.. (NSF problem??)

I am not using Tape only disk backups..
I ftp'd the backup pieces to new machine
I created a link to duplicate the backup location on the original machine and other locations as pfiles...edited the init file for new control locations etc.
The controlfile was wrapping in the backup piece same backup command
It is an NSF mount point. (Netapp)

Is there a solution with the NFS issue?

Brian - First, congratulations on performing what seems pretty close to a disaster recovery test. I don't know the specific answer to your problem, so I'll ask a couple of questions related to hard points I encountered, and maybe that will strike a cord.

You say you connected to your existing RMAN catalog? How does the catalog know to recover this new database and not the one it backed up? Maybe it is confused. I found it much simpler to recover from the controlfile even if I used the catalog to perform the backup. Also in a true disaster, you may not have your RMAN catalog unless you have another tape. If you can recover from the single tape with the RMAN backup, then your offsite tape could get you up and running.
Are the backup pieces in the same path as you backed them up? I don't think that is your problem because that usually gives a clear error.
Are you using NFS? I encountered a problem with NFS very similar to your symptoms. My sys admin assumed there would be only a connection or two over NFS, so left some stuff default. Come to find out RMAN opens a bunch of connections.

Sorry, but that is all my brain can think up on Friday.

Goal: To restore the database from RMAN backup on a different server by means of moving the backup pieces and logs over to the new machine and use Rman to unpack the database files.
Strategy: To restore the database from the RMAN backup pieces into a new directory locations on the machine and extract the control file and startup the database.

Some of the steps to setup the new machine.

1) Install oracle 8i
2) install the patch 4.0
3) copy .profile over
4) duplicated the Admin directories for the database to be restored
5) created a big mount  /u02/vssppln/ point for all the datafiles and

controlfiles and so on
6) Created a backup mount point to store the RMAN backup pieces and archivelogs

7) moved the backup pieces and archivelogs to the new machine
8) Setup and confirm connectivity to Rman catalog
9) No mount the database to be on the new machine

10) Launch the Rman command
rman cmdfile=restore_dbsid.rman trace=restore_dbsid.log

Problem... I run this restore from Rman backup...but it gets to processing the command and gets to the "RMAN-03022: compiling command: set " and just hangs...adding another line every 1/2 hour or so...

Anybody seen this or have ideas? I talked to one guy who did have this but couldn't remember the solution. This is the first time doing this so I might be missing something simple..

Here is the command in operation

==> rman cmdfile=restore_dbsid.rman trace=restore_dbsid.nohup_log
