---------检查监听是否正常
---------启动agent
---------检查gc状态
srvctl relocate service -d -s -I -t
将当前运行在DGDB2的SDG服务切换回DGDB1实例
srvctl relocate service -d dgdb -s sdg -i dgdb2 -t dgdb1（如没有用户连接，可在30秒内完成操作）
执行该操作会自动中止用户连接，建议服务切换时，先通知开发商停止用户，同时使用以下服务启停方式进行切换。
启动服务：srvctl start service -d dgdb -s sdg -i dgdb1
停止服务：srvctl stop service -d dgdb -s sdg

其实运行一下 srvctl -help 一切操作都很清楚了。
