DUPLICATING ORACLE DATABASE USING RMAN |ORACLE 10g

Exploring the Oracle DBA Technology by Gunasekaran , Thiyagu

DUPLICATE ORACLE DATABASE ( DIFFERENT DIRECTURE 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 : rose

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

Auxiliary database path = /u02/app/oracle/oradata/rose/

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

AUXILIARY SERVER 192.168.241.132 (OEL5.SERVER2.COM) SERVER2 DEVELOPMENT

log_file_name_convert=('/u01/app/oracle/oradata/sham/', '/u02/app/oracle/oradata/rose/')

If the source database directory structure &clone database directory structure differs, then only

you need to use db_file_name_convert&log_file_name_convertparameters. In my case, i am using

different mount point, so need to add above two parameters in pfile for auxiliary database.
