Step by Step - Physical Standby Setup using DUPLICATE in Oracle Database 11g Release 2

Step by Step - Physical Standby Setup using DUPLICATE in Oracle Database 11g Release 2

My Server Details:-
Primary Database - HCLDB - Sever - 192.168.195.128
Standby Database - HCLDB_STBY - Sever - 192.168.195.138
Oracle 11GR2 on RHEL5

Step1. Make sure your Primary DB is in Archivelog mode and Force logging is enabled if not put you DB in Archivelog mode

SQL> archive log list
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     1
Next log sequence to archive   2
Current log sequence           2

**Enable forced logging by issuing the following command.

SQL> ALTER DATABASE FORCE LOGGING;

Database altered.

Step2. Check the setting for the DB_NAME and DB_UNIQUE_NAME parameters. In this case they are both set to "HCLDB" on the primary database.

SQL> show parameter db_name

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_name                              string      HCLDB
SQL> show parameter db_unique_name

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_unique_name                       string      HCLDB

Step3. The DB_UNIQUE_NAME values of the primary and standby database should be used in the DG_CONFIG setting of the LOG_ARCHIVE_CONFIG parameter.

SQL> ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(HCLDB,HCLDB_STBY)';

System altered.

Step4. Set suitable remote archive log destinations.

SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=HCLDB_STBY NOAFFIRM ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=HCLDB_STBY';

System altered.

SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE;

System altered.

Step5. Set LOG_ARCHIVE_FORMAT and LOG_ARCHIVE_MAX_PROCESSES parameters

SQL> ALTER SYSTEM SET LOG_ARCHIVE_FORMAT='%t_%s_%r.arc' SCOPE=SPFILE;
ALTER SYSTEM SET LOG_ARCHIVE_MAX_PROCESSES=30;
ALTER SYSTEM SET REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE SCOPE=SPFILE;

Step6. make sure the primary is ready to switch roles to become a standby

SQL> ALTER SYSTEM SET FAL_SERVER=HCLDB_STBY;
ALTER SYSTEM SET DB_FILE_NAME_CONVERT='HCLDB_STBY','HCLDB' SCOPE=SPFILE;
ALTER SYSTEM SET LOG_FILE_NAME_CONVERT='HCLDB_STBY','HCLDB'  SCOPE=SPFILE;
ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO;

Step7. Configure tnsnames on both servers.

>>>> tnsnames.ora entry
-------------------------------------------------------------------
HCLDB =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.128)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = HCLDB)
    )
  )

HCLDB_STBY =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.138)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = HCLDB_STBY)

    )
  )
-----------------------------------------------------------------------------

>>>>> listener.ora entry at Primary
------------------------------------------------------------------------------
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = HCLDB)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = HCLDB)
    )
  )


LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.128)(PORT = 1521))
  )
-----------------------------------------------------------------------------------

>>>>>listener.ora entry at Standby
-------------------------------------------------------------------------------------
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = HCLDB_STBY)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = HCLDB_STBY)
    )
  )


LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.138)(PORT = 1521))
  )
---------------------------------------------------------------------------------------

Start listenter on both servers and confirm with tnsping

Step8. Copy the Primary DB init file (initHCLDB) to Standby server and rename the init file to initHCLDB_STBY

scp oracle@192.168.195.128:/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initHCLDB.ora /u01/app/oracle/product/11.2.0/dbhome_1/dbs/
cp initHCLDB.ora initHCLDB_STBY.ora

Step9. Create orapwd file at Standby DB
orapwd file=orapwHCLDB_STBY password=oracle entries=10

Step10. Connect to Standby server and start in NOMOUNT stage

[oracle@localhost dbs]$ . oraenv
ORACLE_SID = [HCLDB_STBY] ?
ORACLE_HOME = [/home/oracle] ? /u01/app/oracle/product/11.2.0/dbhome_1/
The Oracle base for ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1/ is /u01/app/oracle
[oracle@localhost dbs]$ sqlplus sys/oracle@HCLDB_STBY as sysdba
