Backup & Recovery :: Changing Location Of Data And Temp Files From Auto-backup Of Control-file?

I have an oracle autoback of controlfile and spfile. I am trying to restore the production database using this backup, into a new server with a different directory structure.

I have completed the following steps in the restore process.

1. Creating a pfile from spfile

2. Changing the the location of cdump, udump, bdump and the control files ( there are three )

3. Then creating a spfile from this pfile

I am stuck on the next step where to rename all the datafiles and tempfile and restore the database. Following is what I did.

After mounting the database in RMAN, tried to run the following.

RMAN> run
2> {
3> allocate channel c1 device type disk
4> ;
5> @/home/oracle/rman_scripts/newloc.rman
6> SET NEWNAME FOR DATAFILE 1 TO '/u02/oradata/dorian/system01.dbf';
7> SET NEWNAME FOR DATAFILE 2 TO '/u02/oradata/dorian/undotbs01.dbf';
8> SET NEWNAME FOR DATAFILE 3 TO '/u02/oradata/dorian/sysaux01.dbf';
9> SET NEWNAME FOR DATAFILE 4 TO '/u02/oradata/dorian/users01.dbf';

[code]....

I am getting the following error message.
