Duplicating a Database with RMAN

Operating Environment Windows XP Prof. SP-2
Oracle Release / Version 10.1.0.2.0 Enterprise Edition
ORACLE_BASE d:\oracle
ORACLE_HOME d:\oracle\product\10.1.0
Target Database SID ORA101
Duplicate Database SID TESTDB
RMAN Catalog Database No recovery catalog. Using control file.
Archive Log Mode Enabled
-----------------------------------------------------------------------------------------------
1.Create password File for duplicate database

C:\>orapwd file=d:\oracle\product\10.1.0\db_2\database\pwdtestdb.ora password=oracle entries=5 force=y

----------------------------------------------------------------
2.Create Init.ora file for duplicate database. copy init.ora file from target database (ora101) and edit.


SQL> create pfile='d:\oracle\product\10.1.0\db_2\database\initTESTDB.ora' from spfile;
File created.


#Minimum Changes in init.ora file
db_file_name_convert = ('d:\oracle\product\10.1.0\oradata\ORA101','d:\oracle\product\10.1.0\oradata\TESTDB')
log_file_name_convert = ('d:\oracle\product\10.1.0\oradata\ORA101','d:\oracle\product\10.1.0\oradata\TESTDB')
background_dump_dest='D:\oracle\product\10.1.0\admin\testdb\bdump'
control_files='D:\oracle\product\10.1.0\oradata\testdb\control01.ctl','D:\oracle\product\10.1.0\oradata\testdb\control02.ctl','D:\oracle\product\10.1.0\oradata\testdb\control03.ctl'
core_dump_dest='D:\oracle\product\10.1.0\admin\testdb\cdump'
db_name='testdb'
dispatchers='(PROTOCOL=TCP)(SERVICE=testdbXDB)'
user_dump_dest='D:\oracle\product\10.1.0\admin\testdb\udump'

---------------------------------------------------------------------------------------------
3.Create / Start the Auxiliary Instance (Duplicate Database)


Create all required directory.
C:\>mkdir d:\oracle\product\10.1.0\admin\TESTDB\bdump
C:\>mkdir d:\oracle\product\10.1.0\admin\TESTDB\cdump
C:\>mkdir d:\oracle\product\10.1.0\admin\TESTDB\udump

hai taj do you have document for creating oracle 9i replication.If possible the please mail it to me.My email id is b_kareem@hotmail.com

Mohammad Taj said...

Hi,

I don't have specific documentation for oracle 9i replication.
but can use oracle documentation.
http://download.oracle.com/docs/cd/B10501_01/server.920/a96567/toc.htm

If you done on XP you missed out... service creation i gues...
I mean we may have to create service manually in Windows environment...

Mohammed Taj said...

Did you check Step:3?

3.Create / Start the Auxiliary Instance (Duplicate Database)



C:\>ORADIM -NEW -SID TESTDB
Instance created.

Wow excellent task

I was looking for this kind of step last two days but didnot find. But you mentioned in very clear steps

Thanks

I just want to know how you get scn number ?

Thanks
Rahul
