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';
