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.

In this article we will see step by step instructions on how to configure dataguard broker configuration using DGMGRL utility. The dataguard broker makes it easy to maintain and administer several standby databases. Dataguard broker maintains its own configuration files and runs a background process DMON both on primary and standby database servers. Dataguard broker configuration can be created using either OEM grid control or using a command line utility DGMGRL. In the present article we are using DGMGRL to create dataguard broker configuration to maintain standby databases.

1. Stop Managed Recovery Process On Standby Database
2. Shutdown Standby Database
3. Connect To Primary Database As SYS
4. Create A New Physical Standby Controlfile From The Primary
5. Copy Created Controlfile to Standby Server
6. Mount Standby Database With Newly Created Controlfile
7. Rename Datafiles ( Optional If db_file_name_convert and log_file_name_convert are specified)
8. Create Standby Redo Logs ( Optional )
9. Re-Enable Flashback
10. Start Managed Recovery

In this demo I am using cold backup of the primary database. There are various other options like RMAN duplicate from active database to create physical standby database without even having the primary database backup in 11g. But in this article I am showing setup without RMAN and using simple sql commands.

Create a temporary directory (/tmp/askm/) on primary server and copy all the controlfile,online redolog files and database files to this location after shutting down the database.

Do some redo log switches

SQL> ALTER SYSTEM SWITCH LOGFILE;

On Standby:
  Verify that the recent archived log file is shifted to standby side and applied with the following commands.

select archived_thread#, archived_seq#, applied_thread#, applied_seq# from v$archive_dest_status;
select registrar, creator, thread#, sequence#, first_change#, next_change# from v$archived_log;
select thread#, sequence#, first_change#, next_change# from v$log_history;

To Verify Recover Process On Standby:

select thread#, sequence# from v$log where status='CURRENT'; = > On Primary
select thread#, sequence#, status from v$managed_standby where process='MRP0'; = > On Standby

The following steps are useful to delete the backups which are marked as NO-EXPIRE. No expire backup are the backups for which the retention policy will not apply and the backups remain till you manually and forcibly delete these backups.  The best example for No-expire backups are the backups kept for training purposes. After successfully creating any training environment, we will backup the database with NO-Expire option and these backups will be used to refresh the database every week.

The following commands show you how to delete these no-expire backups on tape from  RMAN CATALOG. This is useful in cases where if you made any changes to the databases and need to preseve these changes in the database forever, you will take new NO-EXPIRE backups and delete the old backups.
