Creating Physycal Standby With RMAN Recovery Option

Posted by Srikrishna Murthy Annam on December 19, 2011

In this article, I am going to explain step by step procedure to create a physical standby database using RMAN with database restore and recovery. We can also create physical standby database using RMAN duplicate, but in this article we are creating physical standby database without duplicate command.

  1. Backup primary database ( including archive logs)
  2. Backup controlfile for Standby database
  3. Copy created RMAN backups to standby server
  4. Modify init.ora parameters on primary and standby servers
  5. Configure listener.ora and tnsnames.ora on primary and standby
  6. Verify the connectivity on primary and standby
  7. Restore database on the standby server
  8. Recover database on the standby server
  9. Put the database in Managed Recovery mode on standby server


1. Backup Primary Database :

In this step we are backing up primary database including archive logs.

4. Modify init.ora parameters on primary and standby servers  :

On Primary :

DB_NAME=orcl
DB_UNIQUE_NAME=orcl
LOG_ARCHIVE_CONFIG=’DG_CONFIG=(orcl,sbyorcl)’
LOG_ARCHIVE_DEST_1=’LOCATION=/home/oracle/app/oracle/flash_recovery_area/orcl/ VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=orcl’
LOG_ARCHIVE_DEST_2=’SERVICE=sbyorcl ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=sbyorcl’
LOG_ARCHIVE_DEST_STATE_1=ENABLE
LOG_ARCHIVE_DEST_STATE_2=ENABLE
REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE
LOG_ARCHIVE_FORMAT=%t_%s_%r.arc
LOG_ARCHIVE_MAX_PROCESSES=30
FAL_SERVER=sbyorcl
DB_FILE_NAME_CONVERT=’sbyorcl’,’orcl’
LOG_FILE_NAME_CONVERT=’/home/oracle/app/oracle/flash_recovery_area/sbyorcl/’,’/home/oracle/app/oracle/flash_recovery_area/orcl/’
STANDBY_FILE_MANAGEMENT=AUTO

On Standby :

DB_NAME=orcl
DB_UNIQUE_NAME=sbyorcl
LOG_ARCHIVE_CONFIG=’DG_CONFIG=(orcl,sbyorcl)’
CONTROL_FILES=’/home/oracle/app/oracle/oradata/sbyorcl/s_control01.ctl’, ‘/home/oracle/app/oracle/flash_recovery_area/sbyorcl/s_control02.ctl’
DB_FILE_NAME_CONVERT=’orcl’,’sbyorcl’
LOG_FILE_NAME_CONVERT=’/home/oracle/app/oracle/flash_recovery_area/orcl/’,’/home/oracle/app/oracle/flash_recovery_area/sbyorcl/’
LOG_ARCHIVE_FORMAT=%t_%s_%r.arc
LOG_ARCHIVE_DEST_1=’LOCATION=/home/oracle/app/oracle/flash_recovery_area/sbyorcl/ VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=sbyorcl’
LOG_ARCHIVE_DEST_2=’SERVICE=orcl ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=orcl’
LOG_ARCHIVE_DEST_STATE_1=ENABLE
LOG_ARCHIVE_DEST_STATE_2=ENABLE
REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE
STANDBY_FILE_MANAGEMENT=AUTO
FAL_SERVER=orcl

5. Configure listener.ora and tnsnames.ora on primary and standby :

On Primary :

[oracle@dgaskmpri01 admin]$ cat listener.ora
LISTENER_PRI =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1525))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dgaskmpri01.localdomain)(PORT = 1525))
)
)

SID_LIST_LISTENER_PRI =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME = /home/oracle/app/oracle/product/11.2.0/dbhome_2)
(SID_NAME = orcl)
)
)
[oracle@dgaskmpri01 admin]$ cat tnsnames.ora
orcl =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dgaskmpri01.localdomain)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID=orcl)
)
)

sbyorcl =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dgaskmsby01.localdomain)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID=sbyorcl)
)
)
[oracle@dgaskmpri01 admin]$

On Standby :

[oracle@dgaskmsby01 admin]$ cat listener.ora
LISTENER_SBY =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1525))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dgaskmsby01.localdomain)(PORT = 1525))
)
)

SID_LIST_LISTENER_SBY =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME = /home/oracle/app/oracle/product/11.2.0/dbhome_2)
(SID_NAME = sbyorcl)
)
)
[oracle@dgaskmsby01 admin]$ cat tnsnames.ora
orcl =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dgaskmpri01.localdomain)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID=orcl)
)
)

sbyorcl =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dgaskmsby01.localdomain)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID=sbyorcl)
)
)
[oracle@dgaskmsby01 admin]$

6. Verify the connectivity on primary and standby :

On Primary Server:
[oracle@dgaskmpri01]$ lsnrctl stop LISTENER_PRI
[oracle@dgaskmpri01]$ lsnrctl start LISTENER_PRI
[oracle@dgaskmpri01]$ tnsping orcl
[oracle@dgaskmpri01]$ tnsping sbyorcl
[oracle@dgaskmpri01]$ sqlplus sys/xxxxx@orcl
[oracle@dgaskmpri01]$ sqlplus sys/xxxxx@sbyorcl

On Standby Server:
[oracle@dgaskmsby01]$ lsnrctl stop LISTENER_SBY
[oracle@dgaskmsby01]$ lsnrctl start LISTENER_SBY
[oracle@dgaskmsby01]$ tnsping orcl
[oracle@dgaskmsby01]$ tnsping sbyorcl
[oracle@dgaskmsby01]$ sqlplus sys/xxxxx@orcl
[oracle@dgaskmsby01]$ sqlplus
sys/xxxxx@sbyorcl

7. Restore database on the standby server :

[oracle@dgaskmsby01 dbs]$ rman target /

8. Recover database on the standby server :

In the recovery we need to recover database till the sequence number that we backed up on primary. So we first need to find out the sequence until which we need to recover database. As we got the controlfile on standby server from primary, it contains the archive log information.

RMAN>

The last sequence number from the above session log is 453. So we need to recover database on standby untill sequence number 454.

RMAN> recover database until sequence 454;

Starting recover at 21-NOV-11
using channel ORA_DISK_1

starting media recovery

channel ORA_DISK_1: starting archived log restore to default destination

RMAN> exit

If you get any warnings, ( something like we got in the above session log) , we can ignore it.

9. Put the database in Managed Recovery mode on standby server :

[oracle@dgaskmsby01 dbs]$ sqlplus ‘/as sysdba’

SQL*Plus: Release 11.2.0.2.0 Production on Mon Nov 21 05:59:36 2011

Copyright (c) 1982, 2010, Oracle.  All rights reserved.

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 – Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT FROM SESSION;

Database altered.

SQL> select database_role,switchover_status from v$database;

DATABASE_ROLE    SWITCHOVER_STATUS
—————- ——————–
PHYSICAL STANDBY TO PRIMARY

SQL> SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;

Verify on the Primary :

[oracle@dgaskmpri01 askm]$ sqlplus ‘/as sysdba’

SQL*Plus: Release 11.2.0.2.0 Production on Mon Nov 21 06:01:51 2011

SQL> select database_role,switchover_status from v$database;

DATABASE_ROLE    SWITCHOVER_STATUS
—————- ——————–
PRIMARY          RESOLVABLE GAP

SQL>

SQL> select database_role,switchover_status from v$database;

DATABASE_ROLE    SWITCHOVER_STATUS
—————- ——————–
PRIMARY          TO STANDBY

SQL>

This is how we will create physical standby database with RMAN recovery option. I am going to explain in my next article the process of creating a physical standby database with RMAN duplicate option.
