Oracle Database: RAC 2 Nodes - Standby and DG Broker Build - Part 1

In this blog I show how to configure Dataguard Broker configuration for a 2-node RAC cluster to a 2-Node Standby.
This is a 2 blog series - you can find the second blog here - which only talks about configuration of Dataguard and Broker.

Here is my configuration
Production DB
Unique Name - MYDBPROD
 - Instance 1 - MYDBPR11
 - Insance 2 - MYDBPR12


Unqiue Name - MYDBSTDBY
 - Instance 1 - MYDBPR11
 - Insance 2 - MYDBPR12


Step 1 - Create tnsnames.ora entries in all nodes
MYDBPROD =

  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = MYPRODDB-PRD-SCAN)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = MYDBPROD)
        (UR = A)
    )
  )

MYDBSTDBY =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = MYSTDBYDB-PRD-SCAN)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = MYDBSTDBY)
        (UR = A)
    )
  )

Step 2 - Static Listener Entries for DG broker operations

[Node 1 - Grid user Standby Cluster]
File - $ORACLE_HOME/network/admin/listener.ora
SID_LIST_LISTENER =
 (SID_LIST =
  (SID_DESC =
    (GLOBAL_DBNAME = MYDBSTDBY_DGMGRL)
    (ORACLE_HOME = <OH>)
    (SID_NAME = MYDBPR11)
  )
  (SID_DESC =
    (GLOBAL_DBNAME = MYDBSTDBY)
    (ORACLE_HOME = <OH>)
    (SID_NAME = MYDBPR11)
  )
 )


lsnrctl stop
lsnrctl start

[Node 1 - Grid user Standby Cluster]
File - $ORACLE_HOME/network/admin/listener.ora


SID_LIST_LISTENER =
 (SID_LIST =
  (SID_DESC =
    (GLOBAL_DBNAME = MYDBSTDBY_DGMGRL)
    (ORACLE_HOME = <OH>)
    (SID_NAME = MYDBPR12)
  )
 )



lsnrctl stop 
lsnrcl start

[Node 1- Grid user - Primary Cluster]
File - $ORACLE_HOME/network/admin/listener.ora
SID_LIST_LISTENER =
 (SID_LIST =
  (SID_DESC =
    (GLOBAL_DBNAME = MYDBPROD_DGMGRL)
    (ORACLE_HOME = <OH>)
    (SID_NAME = MYDBPR11)
  )
 )


lsnrctl stop
lsnrctl start

[Node 2 - Grid user - Primary Cluster]
File - $ORACLE_HOME/network/admin/listener.ora
SID_LIST_LISTENER =
 (SID_LIST =
  (SID_DESC =
    (GLOBAL_DBNAME = MYDBPROD_DGMGRL)
    (ORACLE_HOME = <OH>)
    (SID_NAME = MYDBPR12)
  )
 )

lsnrctl stop
lsnrctl start

Step 3 - Reset sys and system password and copy password file from Node 1 of Primary to other 3 nodes (in $ORACLE_HOME/dbs), also change the name as per the name of the instance

Step 4 -  Add Database and Instance in OCR registry 

[Node 1 - oracle user - Standby Cluster]
srvctl add database -d MYDBSTDBY -o /opt/oracle/product/112/db -c RAC \
-p +DATA/MYDBSTDBY/spfileMYDBSTDBY.ora -r PHYSICAL_STANDBY -s MOUNT -t IMMEDIATE -n <DB_NAME> -a DATA,REDO1,FRA

srvctl add instance -d MYDBSTDBY -i MYDBPR11 -n Node1
srvctl add instance -d MYDBSTDBY -i MYDBPR12 -n Node2

Step 5 - Create init files

[Node 1 - oracle user - Standby Cluster]
cd /opt/oracle/product/112/db/dbs
cat initMYDBPR11.ora
SPFILE='+DATA/MYDBSTDBY/spfileMYDBSTDBY.ora'

[Node 2 - oracle user - Standby Cluster]
cd /opt/oracle/product/112/db/dbs
cat initMYDBPR12.ora
SPFILE='+DATA/MYDBSTDBY/spfileMYDBSTDBY.ora'

Step 6 - Create Audit Directories

[Node 1 - oracle user - Standby Cluster]
mkdir -p /opt/oracle/base/admin/MYDBSTDBY/adump

[Node 2 - oracle user - Standby Cluster]
mkdir -p /opt/oracle/base/admin/MYDBSTDBY/adump

Step 7 - Start the instance, mount it and recover standby database. 
You can use any method to recover/restore.
One of the methods which I recommend is to use active database duplication. It's generally faster. 

rman << EOF
connect TARGET sys/<pwd>@MYDBPROD ;
connect AUXILIARY sys/<pwd>@MYDBSTDBY;
DUPLICATE TARGET DATABASE
FOR STANDBY
FROM ACTIVE DATABASE
DORECOVER
NOFILENAMECHECK;
