Oracle Database Discussions

Hello DBA's

I need to restore a Database Into Another Server to Retrieve Some data from tables delete accidentraly by Users.

I'm having some pb to restore a Database into another Host, quite probable a issue with the script.
just FYI RH5 on Oracle 10.2.0.4 but the issue is surely the Script.
So I've Restore the RMAn Backup files into another host :
[oracle@srvldbp12 ORA_BACKUP_CPQ]$ ls -lrt
total 720016
-rw-r----- 1 oracle oinstall 17920 Feb 23 09:25 CPQ_180220100218_full_29l69gvb_1_1
-rw-r----- 1 oracle oinstall 180224 Feb 23 09:25 CPQ_180220100218_full_28l69gv9_1_1
-rw-r----- 1 oracle oinstall 728825856 Feb 23 09:25 CPQ_180220100218_full_27l69goi_1_1
-rw-r----- 1 oracle oinstall 7536640 Feb 23 09:32 cf_c-3474491432-20100218-00_CPQ
[oracle@srvldbp12 ORA_BACKUP_CPQ]$

these Backups are from "CPQ" database and I would like to restore Into This Server srvldbp12 but Renaming database CPQ into CPQR
So
I've Created all File System
Created the initCPQR.ora with all parameters "CPQR" instead "CPQ"
I Startup nomount the database "CPQR"
Then I Start RMAN a Follows :

[oracle@srvldbp12 index]$ rman target sys/l3dz3p1@sncpq
Recovery Manager: Release 10.2.0.4.0 - Production on Tue Feb 23 09:52:35 2010
connected to target database: CPQ (DBID=3474491432)
RMAN> connect auxiliary /
connected to auxiliary database: CPQR (not mounted)
RMAN>
Than i run Script Below:
run
{
allocate auxiliary channel ch1 type disk;
set newname for datafile 1 to '/u02/oradata/CPQR/system/system01.dbf';
set newname for datafile 2 to '/u02/oradata/CPQR/system/undotbs1.dbf';
set newname for datafile 3 to '/u02/oradata/CPQR/system/sysaux01.dbf';
set newname for datafile 4 to '/u01/oradata/CPQR/data/users01.dbf';
set newname for datafile 5 to '/u01/oradata/CPQR/data/cogix_data_01.dbf';
set newname for datafile 6 to '/u03/oradata/CPQR/index/cogix_index_01.dbf';
set newname for datafile 7 to '/u01/oradata/CPQR/data/surveytool_data_01.dbf';
set newname for datafile 8 to '/u03/oradata/CPQR/index/surveytool_index_01.dbf';
set newname for datafile 9 to '/u01/oradata/CPQR/data/tools_01.dbf';
set newname for tempfile 1 to '/u02/oradata/CPQR/system/temp01.dbf';
duplicate target database to CPQR
PFILE = $ORACLE_HOME/dbs/initCPQR.ora
LOGFILE group 1 (
'/u01/oradata/CPQR/rdo/redo01.log',
'/u01/oradata/CPQR/rdo/redo04.log') size 20M,
group 2 (
'/u01/oradata/CPQR/rdo/redo02.log',
'/u01/oradata/CPQR/rdo/redo05.log') size 20M,
group 3 (
'/u01/oradata/CPQR/rdo/redo03.log',
'/u01/oradata/CPQR/rdo/redo06.log') size 10M;
}
