Restore controlfile,database(PIT) from backups(non-defualt location)

Question

Hi,
Below is the script i m using to do db point-in-time recovery. But the problem is the backups was taken in a non-defualt location and i want the restore and recovery to be happened from there. Mostly facing issue with controlfile recovery. Just don't know how to tell RMAN that my controlfile rman backup is in non-defualt location '/fulldbbackup/'
backup Script
run{
        allocate channel ch1 device type disk ;
        backup database TAG = 'DR_test_backup' format '/fulldbbackup/%D_RMAN_DATAFILE_BACKUP_%U.bak';
        sql 'alter system archive log current';
        backup archivelog all delete input TAG = 'DR_test_backup2' format '/fulldbbackup/%D_RMAN_ARCHIVELOG_%U.bak';
     backup current controlfile TAG='DR_test_backup' format '/fulldbbackup/%D_RMAN_CURRENT_CONTROL_BACKUP_%U.bak';
==============================================================
rman target / nocatalog
RMAN> sql "alter session set nls_date_format = ''dd.mm.yyyy hh24:mi:ss''";
RMAN> CROSSCHECK BACKUPPIECE TAG = 'DR_TEST_BACKUP';

You can restore control file by specifying the path explicitly.
-- In the auxillary server
Make sure you have the CONTROL_FILES parameter in the pfile. The control files will be restored to this path
*.control_files='+LMNPROD_DG01/lmnprod/lmnprod_control01.ctl','+LMNPROD_DG01/lmnprod/lmnprod_control02.ctl','+LMNPROD_DG01/lmnprod/lmnprod_control03.ctl'Create spfile from pfile. Then
SQL> conn / as sysdba
Connected to an idle instance.
SQL> startup nomount
SQL> show parameter spfileStep5. Restore Control file
The below command will create all the 3 control files mentioned in CONTROL_FILES parameter in the spfile.
$ rman target /
restore controlfile from '/path_where_bkp_piece_is_stored/RMAN_CURRENT_CONTROL_BACKUP_0mnbvhlq_1_1.bak';After restoring the control file and mounting the DB , you can use CATALOG command to catalog backup pieces
