How to restore a database from host A to host B by using RMAN

Question

Hi there
I wanted to restore 1 database from machine A to machine B with the differente files systemes. I did these steps below, but I have a problem when I restore the controlfile from machine A to machine B.
1-copy the controlfile from machine A to machine B by using OS utility.
2-startup nomount the database on machine B.
3-connect target and catalog RMAN.
4-I have to restore the controlfile from last full backup of the machine A to machine B (see the procedure RMAN).
I have the error messages like:
RMAN> connect target /
RMAN-06006: connected to target database: dbtest (not mounted)
RMAN> connect catalog rman/rman@rcattest
RMAN-06008: connected to recovery catalog database
RMAN> run {
2> allocate channel c1 type 'sbt_tape' ;
3> restore controlfile ;
4> }

Hi there
I'm also trying to restore a full RMAN backup to our DR site using Netbackup as MML
My scenario is:
We have one tape library at our PROD data center and another one at our DR site both using Netbackup as Storage manager
I performed a full RMAN backup on 4 DLT tapes with recovery catalog at our PROD datacenter, then I removed the 4 tapes and place it in our tape lib at DR site
I tried to import the tapes using bpimport from Netbackup which has been successful up to now
But when I tried to restore controlfile from RMAN, I get the following error:
connected to target database: prod (not mounted)
connected to recovery catalog database
RMAN> run {
2> allocate channel c1 type 'SBT_TAPE';
3> allocate channel c2 type 'SBT_TAPE';
4> allocate channel c3 type 'SBT_TAPE';
5> allocate channel c4 type 'SBT_TAPE';
6> set until time '16-AUG-2005 15:00:00';
7> restore controlfile;
8> }
