2.12 状态检查
安装完成后执行gs_om命令检查状态。

2.13 备库只读
设置备库只读。
1）如果主备机上的openGauss数据库实例正在运行，请先分别停止主备机上的数据库实例。
2）分别打开主机与备机的postgresql.conf配置文件，找到并将对应参数修改为：
wal_level=hot_standby hot_standby = on hot_standby_feedback = on
revoke all on schema public from public; create user user1 login identified by "passwd1"; grant all privileges on database db1 to user1;
2.15 高可用切换测试
进行主备切换测试，以及主备故障恢复测试。
## 切主操作。
