3.1 实验目标

3.2 前提条件

1. 设置primary和standby启动时参数文件为spfile

3. 设置listener
在Data Guard Broker环境中，需要在listener.ora静态添加一个service_name为db_unique_name_DGMGRL.db_domain的注册。这个service_name会在DGMGRL重启数据库的时候用到。通过DGMGRL重启数据库时DMON进程会先将数据库关闭，然后DGMGRL用此service_name通过listener连接到数据库，发出启动命令。

在配置broker完成后，我们就可以利用broker完成switchover了。在DGMGRL中只需要简单的一个命令。
switchover to standby-database
