centos 7.5搭建oracle DG

一.背景

1.IP分配
主库：192.168.12.5 node1
备库：192.168.12.6 node2

2.环境
主库已安装数据库软件，已建库，并有业务数据
备库已安装数据库软件，未建库

二、配置主备库网络

1.主库监听：
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.12.5)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /u01/app/oracle

2.主库网络服务：
ORADB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.12.5)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = oradb)
    )
  )

ORADBSTD =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.12.6)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = oradbstd)
    )
  )

3.备库监听：
LISTENER=
  (DESCRIPTION=
      (ADDRESS_LIST=
           (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.12.6)(PORT=1521))
      )
  )

4.备库网络服务：
ORADB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.12.5)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = oradb)
    )
  )

ORADBSTD =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.12.6)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = oradbstd)
    )
  )

5.测试主备网络：
主库：
[oracle@node1 admin]$ tnsping oradb

OK (0 msec)
[oracle@node1 admin]$ tnsping oradbstd

备库：
[oracle@node2 admin]$ tnsping oradb

OK (0 msec)

全部都为OK，主备网络配置完成。

三、主库开启归档模式，开启force logging

sql> alter database archivelog;

Database altered.

sql> alter database force logging;

Database altered.

sql> alter database open;

Database altered.

四、主库添加

主库生成文本参数文件，并修改参数
