Overview
Oracle Recovery Manager (RMAN) provides a comprehensive foundation for efficiently backing up and recovering the Oracle databases, it provides a common interface, via command line and Enterprise Manager, for backup tasks across different host operating systems, automates administration of your backup strategies.
In this scenario we have different database name and different directory structure. And we are transforming the directory structure using SET NEWNAME and this command should be used in Rman run blocks {}
Transforming Directory Names using SET NEWNAME Another technique for instructing RMAN to transform directory names is with the SET NEWNAME command. This command must be encapsulated within an RMAN RUN {} block. Before performing this operation, first verify your target database data file numbers and corresponding names.

Pre-requisites
- Password file from target database.
- Sqlnet.ora should have correct parameters.
- Target database should be running through pfile or spfile.
- Auxiliary instance should be start with pfile in nomount stage.
1. Set Oracle sid on which backup will perform.
[oracle@NSM-SRC dbs]$ hostname
NSM-SRC
[oracle@NSM-SRC dbs]$ export ORACLE_SID=prod
2. Connect to RMAN.
[[oracle@NSM-SRC rman_backup]$ rman target sys/oracle
