Create RAC Standby Database for RAC Primary Database

This article speaks of creating a RAC physical standby database for RAC Primary database.

Primary and Standby databases are of 2 node RAC.

Primary Database : PRIM
DBNAME : PRIM
DB UNIQUE NAME : PRIM
Instances : PRIM1 on node1
PRIM2 on node2

Standby Database : SRPSTB
DBNAME : PRIM
DB UNIQUE NAME : SRPSTB
Instances : SRPSTB1 on drnode1
SRPSTB2 on drnode2

Database version: Oracle 11.2.0.1

Below are the steps to create a RAC standby database for a RAC primary database.

Step 1: Add the following standby parameters on the primary database.

log_archive_dest_1='location=use_db_recovery_file_dest valid_for=(all_logfiles,all_roles) db_unique_name=prim'
log_archive_dest_2='service=srpstb valid_for=(online_logfiles,primary_role) db_unique_name=srpstb'
fal_client='prim' #Oracle net service name of primary database
fal_server='srpstb' #oracle net service name of standby database.

Step 2: Create a pfile of the primary database and copy this file to the standby server.
The contents of the pfile of primary database is as below. (This is the pfile taken from instance prim1 of primary DB.)

[oracle@node1 u02]$ cat initprim1.ora
prim1.__db_cache_size=385875968

prim1.instance_number=1
prim2.instance_number=2
prim1.local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=node1-vip)(PORT=1521))))'
prim2.local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=node2-vip)(PORT=1521))))'
*.log_archive_dest_1='location=use_db_recovery_file_dest

*.remote_login_passwordfile='exclusive'
prim2.thread=2
prim1.thread=1
prim2.undo_tablespace='UNDOTBS2'
prim1.undo_tablespace='UNDOTBS1'

Step 3. Listener File contents on Primary Database server.

[oracle@node1 admin]$ cat listener.ora
LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent
LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1)))) # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent

SID_LIST_LISTENER=
(SID_LIST=
 (SID_DESC=
   (ORACLE_HOME=/u01/app/oracle/product/11.2.0/db1)
   (SID_NAME=prim1)
 )
)

Step 4: TNS entries on primary database server.
### PRIMARY ENTRIES ###

PRIM =
(DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = node-scan)(PORT = 1521))
  (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = prim)
  )
)
PRIM1 =
(DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = node1-vip)(PORT=1521))
  (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = prim)
    (INSTANCE_NAME = prim1)
  )
)

PRIM2 =
(DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = node2-vip)(PORT=1521))
  (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = prim)
    (INSTANCE_NAME = prim2)
  )
)

### Standby TNS ENTRIES ###

SRPSTB =
(DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = drnode-scan)(PORT = 1521)  )
  (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = srpstb)
    (UR = A)
  )
)

SRPSTB2 =
(DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = drnode2-vip)(PORT = 1521)  )
  (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = srpstb)
    (UR = A)
    (INSTANCE_NAME = srpstb2)
  )
)

SRPSTB1 =
(DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = drnode1-vip)(PORT = 1521)  )
  (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = srpstb)
    (UR = A)
    (INSTANCE_NAME = srpstb1)
  )
)

Step 5: Copy the above TNS entries to standby database server node drnode1.

Step 6: Copy the password file of any instance (“orapwprim1” or “orapwprim2”) of primary database located at “$ORACLE_HOME/dbs” location to
the standby database server node drnode1 location “$ORACLE_HOME/dbs” and rename it to “orapwsrpstb1”.

Step 7: On the standby database server, perpare the pfile for srpstb1 instance as initsrpstb1.ora .
Contents of initsrpstb1.ora File:

[oracle@drnode1 dbs]$ cat initsrpstb1.ora
srpstb1.__db_cache_size=419430400
srpstb1.__java_pool_size=16777216
srpstb1.__large_pool_size=16777216
srpstb1.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment
srpstb1.__pga_aggregate_target=520093696
srpstb1.__sga_target=754974720
srpstb1.__shared_io_pool_size=0
srpstb1.__shared_pool_size=285212672
srpstb1.__streams_pool_size=0
*.audit_file_dest='/u01/app/oracle/admin/srpstb/adump'
*.audit_trail='db'
*.cluster_database=false
*.compatible='11.2.0.0.0'
*.control_files='+DATA','+FRA'
*.db_block_size=8192
*.db_create_file_dest='+DATA'
*.db_name='prim'
*.db_unique_name='srpstb'
*.diagnostic_dest='/u01/app/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=srpstbXDB)'
*.log_archive_dest_1='location=use_db_recovery_file_dest valid_for=(all_logfiles,all_roles) db_unique_name=srpstb'
*.log_archive_dest_2='service=prim valid_for=(online_logfiles,primary_role) db_unique_name=prim'
*.db_recovery_file_dest='+FRA'
*.db_recovery_file_dest_size=2G
*.memory_target=1264582656
*.open_cursors=300
*.processes=150
*.remote_listener='drnode-scan:1521'
*.remote_login_passwordfile='EXCLUSIVE'
srpstb1.undo_tablespace='UNDOTBS1'
srpstb1.local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=drnode1-vip)(PORT=1521))))'
srpstb1.fal_client='srpstb1'
*.fal_server='prim'

Step 8: Set up the listener.ora file on the standby database server drnode1.
Contents of Listener.ora file on DRNODE1:

[oracle@drnode1 admin]$ cat listener.ora
LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent
LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1)))) # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent

SID_LIST_LISTENER=
(SID_LIST=
 (SID_DESC=
  (ORACLE_HOME=/u01/app/oracle/product/11.2.0.1/db1)
  (SID_NAME=srpstb1)
 )
)

Step 9: Nomount the standby instance srpstb1 using the above pfile “initsrpstb1.ora”.

Step 10: Now connect to the Primary database as target database and standby database as auxiliary instance through RMAN. Make sure that the
Primary database is open.

[oracle@drnode1 ~]$ rman target sys/oracle@prim auxiliary sys/oracle@srpstb1

Finished Duplicate Db at 25-OCT-13

Step 11: Once the duplication is completed, close the RMAN prompt and connect to the standby database through SQL.

sqlplus sys/<password>@srpstb1 as sysdba

Check the status of the standby database by making sure it is in mount stage.

sql>select status,instance_name,database_role from v$instance,v$database;

Step 12: Now start the managed recovery process on the standby database.

sql>alter database recover managed standby database disconnect from session;

Step 13: Now check if the managed recovery process (MRP) has been started on the standby database or not.

SQL> select process,status,sequence#,thread# from v$managed_standby;

PROCESS STATUS       SEQUENCE# THREAD#
------- ------------ --------- -------
ARCH    CONNECTED    0         0
ARCH    CONNECTED    0         0

RFS     IDLE         0         0
RFS     IDLE         0         0

RFS     IDLE         0         0
RFS     IDLE         0         0
RFS     IDLE         0         0

14 rows selected.

Here, the MRP has been started and is waiting for the log sequence# 39. If MRP is not started, then the above query would not show up the
MRP0 under the process column.
Step 14: On the primary database, perform a few log switches and check if the logs are applied to the standby database.

Primary Database Archive Sequence:

sqlplus sys/<password>@prim1 as sysdba

SQL> select thread#,max(sequence#) from v$archived_log group by thread#;

THREAD# MAX(SEQUENCE#)
------- ----------------
1       76
2       67

Standby database SRPSTB1 archive sequence being applied:

sqlplus sys/<password>@srpstb1 as sysdba

SQL> select thread#,max(sequence#) from v$archived_log where applied='YES' group by thread#;

THREAD# MAX(SEQUENCE#)
------- -----------------
 1      75
 2      67

Here, the maximum sequence# generated on the Primary database from instance 1 (prim1) is 76 and from instance 2 (prim2) is 67 and the maximum sequence# applied on the standby database for thread 1 is 75 and thread 2 is 67 which means that the standby database is in sync with the primary database.
Now lets add the 2nd instance srpstb2 to the Standby Database srpstb.

Step 15: Create a pfile from the standby instance srpstb1 to add the cluster parameters.

cluster_database=TRUE
srpstb1.undo_tablespace='UNDOTBS1'
srpstb2.undo_tablespace='UNDOTBS2'
srpstb2.local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=drnode2-vip)(PORT=1521))))'
srpstb1.instance_number=1
srpstb2.instance_number=2
srpstb1.thread=1
srpstb2.thread=2
srpstb1.fal_client='srpstb1'
srpstb2.fal_client='srpstb2'

The new pfile required for the standby database cluster would look as below.

[oracle@drnode1 dbs]$ cat initsrpstb1.ora
srpstb1.__db_cache_size=402653184
srpstb1.__java_pool_size=16777216
srpstb1.__large_pool_size=16777216

srpstb2.undo_tablespace='UNDOTBS2'
srpstb1.instance_number=1
srpstb2.instance_number=2
srpstb1.thread=1
srpstb2.thread=2
srpstb1.fal_client='srpstb1'
srpstb2.fal_client='srpstb2'
*.fal_server='prim'

Step 16: Shutdown the instance srpstb1, mount it using the newly above pfile, create an spfile to be placed in the shared location (ASM
diskgroup, as it is being shared by both the instances srpstb1 and srpstb2.)

SQL> create spfile='+DATA/SRPSTB/spfilesrpstb.ora' from pfile;

File created.

Step 17: Create a new pfile initsrpstb1.ora in drnode1 located at $ORACLE_HOME/dbs with just one entry to point to the spfile location.

[oracle@drnode1 dbs]$ cat initsrpstb1.ora
SPFILE='+DATA/SRPSTB/spfilesrpstb.ora'

Step 17: Copy the password file of srpstb1 (orapwsrpstb1) to drnode2 location “$ORACLE_HOME/dbs” and rename it as orapwsrpstb2.

Step 18: Copy the newly created pfile (initsrpstb1.ora) fto drnode2 location “$ORACLE_HOME/dbs” and rename it as initsrpstb2.ora

Step 19: Mount both srpstb1 and srpstb2 instances.

Step 20: Start MRP on any one instance using the below query.

SQL> alter database recover managed standby database disconnect from session;

Step 21: Check the max archive sequence generated on primary and compare it with the max archive sequence applied on the standby.

Primary:

SQL> select thread#,max(sequence#) from v$archived_log group by thread#;

Standby:

SQL> select thread#,max(sequence#) from v$archived_log where applied='YES' group by thread#;

Step 22: The next step would be to add the standby database SRPSTB to the cluster.

[oracle@drnode1 ~]$ srvctl add database -d srpstb -o /u01/app/oracle/product/11.2.0.1/db1 -r PHYSICAL_STANDBY -s MOUNT

Step 23: Now, we also need to add the instances entrires to the standby database.

[oracle@drnode1 ~]$ srvctl add instance -d srpstb -i srpstb1 -n drnode1
[oracle@drnode1 ~]$ srvctl add instance -d srpstb -i srpstb2 -n drnode2
