Standby database from RMAN backup

Question

I have been assigned to create a standby database from our RMAN backups in a different machine, as this is my first attempt at recovering, I am struggling a bit. I would appreciate if someone can throw any light on what dumb mistakeI am doing here. I ahve absolutely no control over the back up script which is done by my vendor, but can do anything in the reocvery portion. I did try going through the documentaiton and other help available for the last 2 days.
Database : Oracle 10G R2
OS : Windows Server 2003
My backup script is
configure channel device type disk format 'J:\RMAN\RMAN_df_%U' maxpiecesize 2048M;
SQL "ALTER SYSTEM SWITCH LOGFILE";
SQL "ALTER SYSTEM SWITCH LOGFILE";
backup database;
SQL "ALTER SYSTEM SWITCH LOGFILE";
SQL "ALTER SYSTEM SWITCH LOGFILE";
backup current controlfile for standby FORMAT='J:\RMAN\RMAN_sc_%U';
For recovery of a standby database,
I have copied the the back up pieces and the archive logs to the standby server where I have just created an instance with the same name as production db.
set ORACLE_SID=NGINPROD
set dbid 820336652
STARTUP NOMOUNT
RESTORE STANDBY CONTROLFILE FROM 'I:\TEMP\RMAN_Backup\RMAN\RMAN_SC_2UMIUJM1_1_1';

'I:\TEMP\RMAN_Backup\RMAN\RMAN_SC_2UMIUJM1_1_1';
RESTORE DATABASE;
Till this step I do not encounter any issues, but when i try to recover the database I am hit with the below error.
RMAN> recover database;

Here's the standard dcoumentation on the procedure :
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/rcmbackp.htm#i636377
Appendix "F Creating a Standby Database with Recovery Manager" of the "Oracle® Data Guard Concepts and Administration" guide.
I don't see ArchiveLog backups being done by the vendor's script. How do you backup the ArchiveLogs ?
In your post you state that you have copied the ArchiveLogs. Are they copied to the same log_archive_dest location ? RMAN needs to be "aware" of them. You can use the "CATALOG" command in RMAN to register them into the controlfile.
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta011.htm#sthref230
A Standby Database uses a Standby Controlfile which is created from the Primary (with the "ALTER DATABASE CREATE STANDBY CONTROLFILE AS 'locaion';" command) and then copied over to the Standby server.
