Rman backup based duplication with different DB name and different directory structure with transforming directory structure using SET NEWNAME clause

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.

Target
(source) details:

Database Name
prod
Hostname
NSM-SRC
Ip Address
172.16.110.18
OS
Linux
Version
x86_64
Datafile Location
/data2/prod
Backup Location
/backup/rman_backup
  
Destination details:
Database Name
snname
Hostname
NSM-TRG
Ip Address
172.16.110.16
OS
Linux
Version
x86_64
Datafile Location
/data2/snname/
Backup Location
/backup/rman_backup



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.

Steps on source server:

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

3.    Verify that you target database datafile number and names either from RMAN prompt or from SQL prompt.

Steps on destination server:

7.    Create new directory structure.

[oracle@NSM-TRG dbs]$ mkdir -p /data2/snname/



8.    Edit the pfile to reflect new db name and controlfile location.

[oracle@NSM-TRG dbs]$ vi initsnname.ora

*.db_name=’snname’

*.control_files=’/data2/snname/control01.ctl’,’/data2/snname/control02.ctl’

9.    Create password file in $ORACLE_HOME/dbs directory.

[oracle@NSM-TRG dbs]$ orapwd file=orapwsnname
password=oracle

10.    Start the instance in no mount stage.

[oracle@NSM-TRG dbs]$ export ORACLE_SID=snname
