Oracle数据库集群管理工具停止RAC注意事项
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]$
