Oracle 9i restore from Backup.

Hi all

I'm new to this Im having problems restoring from backup.

First question: I'm trying to restore a backup taken from a AIX 5.1 environment  to a AIX 6.1 ?

The oracle install is at the same level

SQL*Plus: Release 9.2.0.5.0 - Production on Mon Mar 26 20:28:42 2012

I've managed to get the database in the mount status

SQL> startup mount
ORACLE instance started.

Total System Global Area 1110411904 bytes
Fixed Size                   744064 bytes
Variable Size             469762048 bytes
Database Buffers          637534208 bytes
Redo Buffers                2371584 bytes
Database mounted.

when I try and recover the database I get the following error message...

SQL> recover database using backup controlfile until cancel;
