Clone Database on 11g with Duplicate RMAN on same host

Clone database of PRODUCATION on same host is a quite frequent to do task of DBA's.

Use the following simple step to achieve the same.
Step:
1. backup source database through RMAN
2. create needful administration directories (like ORADATA)
3. create init parameter file for duplicate database (using any text editor create the init.ora file)
4. create oracle services via oradim utility
5. create password file for duplicate database via ORAPWD utility
6. configure tns entry for source and target database
7. startup duplicate database in nomount mode with the help of init.ora file
8. connect rman client with target and auxiliary database
9. execute duplicate database command
10. You have done it successfully.
11. create the SPFILE for duplicate database.
12. take backup of duplicate database (optional)


OS: WINDOWS 2003
SOURCE DB: ORG
TARGET DB: DUP


NOTE: 1. FLASH RECOVERY AREA IS NOT CONFIGURED SO BACKUP WILL STORE IN THE %ORACLE_HOME%/database folder
2. OEM is not configured. (FYI)



1. backup source database through RMAN

CMD> set oracle_sid=org
CMD> rman target sys
password: xxxxxxx


RMAN> backup database plus archivelog;




2. create needful administration directories (like ORADATA)
In the 11g , you just need to create directories for ORADATA


3. create init parameter file for duplicate database (using any text editor create the init.ora file)
The following parameter is required. (mandatory)

DB_NAME=dup
control_files=D:\APP\ADMINISTRATOR\ORADATA\dup\CONTROL01.CTL, D:\APP\ADMINISTRATOR\ORADATA\dup\CONTROL02.CTL
db_block_size=8192
db_file_name_convert='D:\app\Administrator\oradata\org','D:\app\Administrator\oradata\dup'
LOG_file_name_convert='D:\app\Administrator\oradata\org','D:\app\Administrator\oradata\dup'





4. create oracle services via oradim utility
CMD>ORADIM -NEW -SID DUP -STARTMODE manual




5. create password file for duplicate database via ORAPWD utility
CMD>ORAPWD FILE=%ORACLE_HOME%\database\pwddup.ora password=oracle




6. configure tns entry for source and target database

ORG =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.4.78)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = org)
    )
  )

7. startup duplicate database in nomount mode with the help of init.ora file
CMD> set oracle_sid=dup
CMD> sqlplus sys/oracle as sysdba
SQL> startup nomount pfile='c:\init_dup.ora' -- my pfile is located under c: drive




8. connect rman client with target and auxiliary database
CMD> rman target sys@org auxiliary sys 
NOTE: i used tns entry to connect to source database and auxiliary database at same time.




9. execute duplicate database command

C:\>rman target sys@org  auxiliary sys
