在rac1节点使用oracle数据库集群管理工具停止rac1上面的实例，使用crs集群工具停掉CRS集群服务：

停止注意：先停止实例，在停止CRS服务

启动注意：先启动CRS，在启动实例   ---启动实例需要在CRS集群中注册

[oracle@HBCADB001 tablespace]$ srvctl stop instance -d hbcadb -i hbcadb1

[oracle@HBCADB001 tablespace]$

在节点2上面通过集群工具检查当前两个实例的状态，我们可以看到节点1上面的实例已经不在运行了：

[oracle@HBCADB002 ~]$ srvctl status database -d hbcadb

Instance hbcadb1 is not running on node hbcadb001

Instance hbcadb2 is running on node hbcadb002

[oracle@HBCADB002 ~]$

观察节点rac1停止的信息，注意查看oracle的相关进程信息

[oracle@HBCADB001allbak]$
