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

(1)

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/

SOURCE SERVER  192.168.241.131  (OEL5.SERVER1.COM)  SERVER1  PRODUCTION AUXILIARY SERVER  192.168.241.132  (OEL5.SERVER2.COM)  SERVER2  DEVELOPMENT

CHECK NETWORK AVAILABILITY BETWEEN TWO SERVERS SERVER 1 :

(2)

SERVER 2 :

CREATE DIRECTORY STRUCTURE FOR AUXILIARY DATABASE $ mkdir -p /u01/app/oracle/oradata/sham/

$ mkdir -p /u01/app/oracle/admin/sham/adump/ $ mkdir -p /u01/app/oracle/admin/sham/bdump/ $ mkdir -p /u01/app/oracle/admin/sham/cdump/ $ mkdir -p /u01/app/oracle/admin/sham/udump/
