DUPLICATING ORACLE DATABASE USING RMAN |ORACLE 10g

Exploring the Oracle DBA Technology by Gunasekaran , Thiyagu

DUPLICATE ORACLE DATABASE ( SAME DIR STRUCTURE )

The process of duplicating the entire database is called CLONING. I am using same SIDfor source

and clone database as sham for duplication the oracle database from one server to another server.

Source database name : sham

Auxiliary database name : sham

Source database path = /u01/app/oracle/oradata/sham/

Auxiliary database path = /u01/app/oracle/oradata/sham/

SOURCE SERVER 192.168.241.131 (OEL5.SERVER1.COM) SERVER1 PRODUCTION
