Database cloning using RMAN

In this workout we have,
Source database="ORACLE"
Duplicate database="CLONEDB"

 Step-1:Create Password file for Auxiliary Database:
C:\Documents and Settings\suvdas>orapwd file='D:\app\EST_Suvendu\product\11.2.0\
dbhome_1\database\PWDclonedb' password=manager

 Step-2: Create Initializing parameter file for auxiliary database:

 
SQL> create pfile='D:\app\EST_Suvendu\product\11.2.0\dbhome_1\database\initCLONEDB.ora' from spfile;
File created.


After creating the initialization parameter for the duplicate database, and change at leastthe following parameters:

           
db_file_name_convert = ('
D:\APP\EST_SUVENDU\oradata


\ORACLE', '
D:\APP\EST_SUVENDU\oradata


\CLONEDB')



log_file_name_convert = ('
D:\APP\EST_SUVENDU\oradata


\ORACLE', '
D:\APP\EST_SUVENDU\oradata


\CLONEDB')



control_files = '
D:\APP\EST_SUVENDU\oradata


\CLONEDB\control01.ctl'


              , '
D:\APP\EST_SUVENDU\oradata


\CLONEDB\control02.ctl'


              , '
D:\APP\EST_SUVENDU\oradata


\CLONEDB\control03.ctl'


db_name = 'CLONEDB'
instance_name = 'CLONEDB'
background_dump_dest = '
D:\APP\EST_SUVENDU


\admin\
CLONEDB

\bdump'

core_dump_dest = '
D:\APP\EST_SUVENDU


\admin\
CLONEDB

\cdump'

user_dump_dest = '
D:\APP\EST_SUVENDU


\admin\
CLONEDB

\udump'

dispatchers = '(PROTOCOL=TCP) (SERVICE=CLONEDBXDB)'
log_archive_dest_1 = 'location=
D:\APP\EST_SUVENDU\oradata


\
CLONEDB

\archive MANDATORY'

Step-3:Create/start Auxiliary database
Create a new Windows service for the duplicate database CLONEDB using oradim: 

C:\Documents and Settings\suvdas> mkdir D:\APP\EST_SUVENDU\oradata\CLONEDB
C:\Documents and Settings\suvdas> mkdir D:\APP\EST_SUVENDU\oradata\CLONEDB\archive
C:\Documents and Settings\suvdas> mkdir D:\APP\EST_SUVENDU\admin\CLONEDB\bdump
C:\Documents and Settings\suvdas> mkdir D:\APP\EST_SUVENDU\admin\CLONEDB\bdump
C:\Documents and Settings\suvdas> mkdir D:\APP\EST_SUVENDU\admin\CLONEDB\create
C:\Documents and Settings\suvdas> mkdir D:\APP\EST_SUVENDU\admin\CLONEDB\bdump\pfile
C:\Documents and Settings\suvdas> mkdir D:\APP\EST_SUVENDU\admin\CLONEDB\bdump\scripts
C:\Documents and Settings\suvdas> mkdir D:\APP\EST_SUVENDU\admin\CLONEDB\bdump\udump
C:\Documents and Settings\suvdas>oradim -new -sid CLONEDB -intpwd manager -start

mode auto -pfile 'D:\app\EST_Suvendu\product\11.2.0\dbhome_1\database\initCLONEDB.ora


 C:\Documents and Settings\suvdas>set ORACLE_SID=CLONEDB

 C:\Documents and Settings\suvdas> sqlplus "/ as sysdba"

 SQL> startup nomount

Step-4:
The listener file should look like below:
# listener.ora Network Configuration File: D:\app\EST_Suvendu\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

LOCALLSNR =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.10.52)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

SID_LIST_LOCALLSNR =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME =CLONEDB )
      (ORACLE_HOME = D:\app\EST_Suvendu\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\EST_Suvendu\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
   (SID_DESC =
      (SID_NAME =oracle )
      (ORACLE_HOME = D:\app\EST_Suvendu\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\EST_Suvendu\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

ADR_BASE_LOCALLSNR = D:\app\EST_Suvendu

#CLRExtProc

Step-5: Mount/Open the source database "oracle" if not open,


C:\Documents and Settings\suvdas> set ORACLE_SID=ORACLE
C:\Documents and Settings\suvdas> sqlplus "/ as sysdba"
SQL> startup open



Step-6:

>rman sys/manager@oracle auxiliary sys/manager@clonedb
it will connect to RMAN session then give below commands:
RMAN>run {
    # Allocate the channel for the duplicate work
    allocate auxiliary channel ch1 type disk;

    # Duplicate the database to CLONEDB
    duplicate target database to CLONEDB;
}
/////////
