RMAN 'Duplicate From Active Database'

Metalink notes - RMAN 'Duplicate From Active Database' Feature in 11G [ID 452868.1]

***Active database duplication Method***

Target Database- HCL
Auxiliary Database- AUX

Step1. Create a pfile for AUX database and create the required directory as well.

db_name='AUX'
diagnostic_dest='/u01/app/oracle'
DB_FILE_name_CONVERT=('/u01/app/oracle/oradata/HCL','/u01/app/oracle/oradata/AUX') 
LOG_FILE_NAME_CONVERT=( '/u01/app/oracle/oradata/HCL','/u01/app/oracle/oradata/AUX')
sga_target=377487360
control_files='/u01/app/oracle/oradata/AUX/control01.ctl'
compatible='11.2.0.0.0'

Step2. Create password file for Auxilary database

orapwd file=orapwAUX password=oracle entries=10

Step3. Configure Listener on Aux
====================================================
SID_LIST_LISTENER = 
  (SID_LIST = 
    (SID_DESC = 
      (GLOBAL_DBNAME = AUX) 
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1) 
      (SID_NAME = AUX) 
    ) 
  )


LISTENER = 
  (DESCRIPTION = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.128)(PORT = 1521)) 
  )
====================================================
Configure Configure Listener on Target
====================================================
SID_LIST_LISTENER = 
  (SID_LIST = 
    (SID_DESC = 
      (GLOBAL_DBNAME = HCL) 
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1) 
      (SID_NAME = HCL) 
    ) 
  )


LISTENER = 
  (DESCRIPTION = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.134)(PORT = 1521)) 
  )
===========================================================

Configure tnsname.ora (In the TARGET and AUXILIARY host)
=================================================================
AUX = 
  (DESCRIPTION = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.128)(PORT = 1521)) 
    (CONNECT_DATA = 
      (SERVER = DEDICATED) 
      (SERVICE_NAME = AUX) 
    ) 
  ) 


HCL = 
  (DESCRIPTION = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.134)(PORT = 1521)) 
    (CONNECT_DATA = 
      (SERVER = DEDICATED) 
      (SERVICE_NAME = HCL)
    ) 
  )
======================================================================
Execute on the TARGET and AUXILIARY host
% tnsping HCL
% tnsping AUX


Step4. Start Auxilary database to nomount stage
SQL> startup nomount pfile='/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initAUX.ora';
ORACLE instance started.

Total System Global Area  376635392 bytes
Fixed Size                  1336652 bytes
Variable Size             121637556 bytes
Database Buffers          247463936 bytes
Redo Buffers                6197248 bytes
SQL> exit

Step.5 
Start RMAN to connect both DB Instances

RMAN> connect target sys/oracle@HCL

connected to target database: HCL (DBID=931429395)

RMAN> connect AUXILIARY sys/oracle@AUX

connected to auxiliary database: AUX (not mounted)

RMAN> 
=================

DUPLICATE TARGET DATABASE TO 'AUX' FROM ACTIVE DATABASE DB_FILE_NAME_CONVERT '/u01/app/oracle/oradata/HCL','/u01/app/oracle/oradata/AUX';

See output below

RMAN> DUPLICATE TARGET DATABASE TO 'AUX' FROM ACTIVE DATABASE DB_FILE_NAME_CONVERT '/u01/app/oracle/oradata/HCL','/u01/app/oracle/oradata/AUX';
