Data Guard Broker Configuration

Today I decided to use Oracle`s magic dgmgrl utility and configure my standby database.

Below you can see my environment:

PRIMARY

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

STATUS     INSTANCE_NAME    DATABASE_ROLE    PROTECTION_MODE
------------ ---------------- ---------------- --------------------
OPEN     FCDBPROD      PRIMARY       MAXIMUM PERFORMANCE

SQL> select max(sequence#) from v$archived_log;

MAX(SEQUENCE#)
--------------
  674

SQL> 


STANBDY

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

STATUS     INSTANCE_NAME    DATABASE_ROLE    PROTECTION_MODE
------------ ---------------- ---------------- --------------------
MOUNTED      FCDBSTND      PHYSICAL STANDBY MAXIMUM PERFORMANCE

SQL> select max(sequence#) from v$archived_log;

MAX(SEQUENCE#)
--------------
  674

SQL> 

Now, set dataguard broker process on both primary and standby databases.

SQL> alter system set dg_broker_start=true;

System altered.

SQL> 


Add a below lines in the listener.ora file on both the primary and standby servers.


On Primary:

   (SID_DESC=
      (GLOBAL_DBNAME=FCDBPROD_DGMGRL)
      (ORACLE_HOME=/u01/app/oracle/product/11.2.0.3/db_1)
      (SID_NAME=FCDBPROD)
   )

On Standby

   (SID_DESC=
      (GLOBAL_DBNAME=FCDBSTND_DGMGRL)
      (ORACLE_HOME=/u01/app/oracle/product/11.2.0.3/db_1)
      (SID_NAME=FCDBSTND)
   )

[oracle@fcdbdb admin]$ vi listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0.3/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.10.178)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

SID_LIST_LISTENER =
 (SID_LIST =
   (SID_DESC=
      (GLOBAL_DBNAME=FCDBPROD_DGMGRL)
      (ORACLE_HOME=/u01/app/oracle/product/11.2.0.3/db_1)
      (SID_NAME=FCDBPROD)
   )
   (SID_DESC =
     (SID_NAME = FCDBPROD)
     (ORACLE_HOME = /u01/app/oracle/product/11.2.0.3/db_1)
   )
 )

ADR_BASE_LISTENER = /u01/app/oracle

ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER = ON





[oracle@fcdbdb_stby admin]$ vi listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0.3/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.10.179)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

SID_LIST_LISTENER =
 (SID_LIST =
   (SID_DESC=
      (GLOBAL_DBNAME=FCDBSTND_DGMGRL)
      (ORACLE_HOME=/u01/app/oracle/product/11.2.0.3/db_1)
      (SID_NAME=FCDBSTND)
   )
   (SID_DESC =
     (SID_NAME = FCDBSTND)
     (ORACLE_HOME = /u01/app/oracle/product/11.2.0.3/db_1)
   )
 )

ADR_BASE_LISTENER = /u01/app/oracle

ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER = ON
[oracle@fcdbdb_stby admin]$ 



Or, instead of you may add

SID_LIST_LISTENER =
 (SID_LIST =
   (SID_DESC =
     (SID_NAME = FCDBPROD)
     (GLOBAL_DBNAME=FCDBPROD_DGMGRL)
     (ORACLE_HOME = /u01/app/oracle/product/11.2.0.3/db_1)
   )
 )


reload listener on both side

[oracle@fcdbdb_stby admin]$ lsnrctl reload




On the primary server, create the Dataguard Broker configuration.

    Although it has actually not been the case in the last one week, crypto has traditionally been the very best bush for typical markets. Its lack of correlation with the supplies, in particular, has been made sure that crypto is a must-have during their failures. This week has seen this trend change. As traditional markets plunged, the crypto market complied with the very same trend. Auto bitcoin bot
