DIRECTORY STRUCTURE IS SAME - RMAN CLONING (10g) - SERVER TO SERVER.pdf

DUPLICATING ORACLE DATABASE USING RMAN

| ORACLE 10g

DUPLICATE ORACLE DATABASE ( SAME DIR STRUCTURE ) The process of duplicating the entire database is called ‘CLONING’. I am using same SID for 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/  192.168.241.131

 (OEL5.SERVER1.COM)  SERVER1

 PRODUCTION

AUXILIARY SERVER  192.168.241.132

 (OEL5.SERVER2.COM)  SERVER2

 DEVELOPMENT
