oracle DG 主备库为RAC及一个主库对多个从库的实验环境搭建

发布时间：2020-08-09 20:18:13 来源：网络阅读：2621 作者：llc018198 栏目：关系型数据库

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：

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)
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)
    )
)
