Restore backup from NON-DEFAULT location

I would like to share. How to restore database backup from non-default location. Using target database control file instead of recovery catalog database trying to create database.

Using CATALOG BACKUPPIECE trying to restore backup from non-default location.

I have one test database name called "TempDb" & database version 10.2.0.4 & linux 32-bit. Now taking full database backup in TempDb under "/dbbackup/backup/TEMPDB"

[oracle@Babu TEMPDB]$ cat tempdb_backup_log
