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.
Here we have maintained same directory structure but different database name.



Environment Details

Target (source) details:

Database Name
prod
Hostname
Nsmsrc01
Ip Address
172.16.110.18
OS
Linux
Version
x86_64
Datafile Location
/data2/prod
Backup Location
/backup/rman_backup

Destination details:

Database Name
dup
Hostname
Nsmtrg
Ip Address
172.16.110.16
OS
Linux
Version
x86_64
Datafile Location
/data2/prod
Backup Location
/backup/rman_backup

 

Pre-requisites
Password file from target database.
Sqlnet.ora should have correct parameters.
Target database should be running through spfile.

Steps on target(source) server
1.    Set Oracle sid 

[oracle@Nsmsrc01 dbs]$ hostname


Nsmsrc01


[oracle@Nsmsrc01 dbs]$ export ORACLE_SID=prod

 

2.    Connect to RMAN.

[oracle@Nsmsrc01 dbs]$ rman target sys/oracle

3.    Issue the following command to initiate backup. Before issue the backup command check the backup location is sat correctly.

RMAN> show all;
