                    192.168.1.211 node2

备库（1） RAC:    192.168.1.247 rac1

                              192.168.1.248 rac2

备库（2） 单实例：192.168.1.219 dataguard

 

以上均为ASM管理。

实验步骤：

  1. 配置备库（1)的静态监听：

    SID_LIST_LISTENER=
           (SID_LIST=
           (SID_DESC=
           (GLOBAL_DBNAME=SMS)
           (ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1)
           (SID_NAME=SMS1)
             )
            )（rac1)

  2. SID_LIST_LISTENER=
           (SID_LIST=
           (SID_DESC=
           (GLOBAL_DBNAME=SMS)
           (ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1)
           (SID_NAME= SMS2)
             )
            )(rac2)

    配置完成后，重启监听：

    在主库TNS文件后追加：

    SMS =
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.220)(PORT = 1521)) 
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.221)(PORT = 1521))
        (CONNECT_DATA =
          (SERVER = DEDICATED)
            (SERVICE_NAME = SMS)
        )
      )

    SMS1 =
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.247)(PORT = 1521))
        (CONNECT_DATA =
          (SERVER = DEDICATED)
            (SERVICE_NAME = SMS)
          (SERVICE_NAME = SMS1)
        )
      )
    SMS2 =
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.248)(PORT = 1521))
        (CONNECT_DATA =
          (SERVER = DEDICATED)
            (SERVICE_NAME = SMS)
         (SERVICE_NAME = SMS2)
        )
      )

    PHUB =
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.219)(PORT = 1521))
        (CONNECT_DATA =
          (SERVER = DEDICATED)
          (SERVICE_NAME = PHUB)
        )
      )
