主库 RAC ：192.168.1.210 node1

                    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)
        )
      )

把standby库添加到集群：

[oracle@rac2 dbs]$ srvctl add database -o /u01/app/oracle/product/11.2.0/db_1/ -p "+DATA/sms/spfileSMS.ora" -n MECBS -r physical_standby -s mount

PRCS-1007 : Server pool SMS already exists

[oracle@rac2 dbs]$ srvctl add instance -d SMS -i SMS1 -n rac1
[oracle@rac2 dbs]$ srvctl add instance -d SMS -i SMS2 -n rac2
[oracle@rac2 dbs]$ srvctl status database -d SMS

[oracle@rac2 dbs]$ srvctl start database -d SMS

在一个节点开启恢复进程：

SQL> alter database recover managed standby database using current logfile disconnect from session;

Database altered.

SQL> select open_mode,name,instance_name from gv$database a ,gv$instance b where a.inst_id=b.inst_id;

OPEN_MODE      NAME      INSTANCE_NAME
