Database Software

Can someone help please?
=================
I am running Oracle 10.2 on AIX 6.1.

I have normally been doing backups of our production database to TSM, but this time, I need to copy the current production database to another server.

Seems pretty simple, right?

Okay, I set all my RMAN configuration parameters to 'disk' and created a fresh backup of the production database to local disk.
Then, I copied my backup set to the second server.

I first started my database nomount, set my DBID, and then restored my controlfile.
No problem. That worked fine.

Next, I tried several variations of restoring the database.
tried simple 'restore database'
as well as run { allocate channel c0 type disk; restore database, release channel c0, }, and then a few other ways.
All attempts are giving me the exact same errors:

RMAN> run {
2> allocate channel c0 type disk;
3> restore database;
4> release channel c0;
5> }

allocated channel: c0
channel c0: sid=651 devtype=DISK

Starting restore at 29-JUL-09

released channel: c0
