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 :
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.

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.

- Backup primary database ( including archive logs)
- Backup controlfile for Standby database
- Copy created RMAN backups to standby server
- Modify init.ora parameters on primary and standby servers
- Configure listener.ora and tnsnames.ora on primary and standby
- Verify the connectivity on primary and standby
- Restore database on the standby server
- Recover database on the standby server
- Put the database in Managed Recovery mode on standby server

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_FILE_NAME_CONVERT='/home/oracle/app/oracle/flash_recovery_area/sbyorcl/','/home/oracle/app/oracle/flash_recovery_area/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 =

)
[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

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.

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.
