Restoring of rman backup

Question

Hi all,
i got a scenerion where i need to check whether rman back is valid or not.
i have y server where production db resides and storage team kept the 7 days old rman backup in the same production server and my resposibility is to reatore the rman backup with new database name in the same server and to query the new db to cross verify that rman backup is valid or not.
oracle version : 9.2.0.4.0
os : windows
appreciated the inputs.
Thanks
Prakash

Can you solve your problem?
Now I explain this for you.Consider we have database which name is "w".We want craete new database (w1) using backup of w in same machine.Also backup of database have located in D:\oracle\product\10.2.0\flash_recovery_area\W.
First we have to create service and some directories for new W1,aslo restore spfile and controlfile as
C:\Documents and Settings\chinar>set ORACLE_SID=W1
C:\Documents and Settings\chinar>rman target sys/sm
