首先是删:

1 dbca删节点 rac1,按提示删除即可,其中需要输入sys密码crsctl unpin css -n rac12#执行完grid用户查看资源池，此时rac2已经不在serverpool里，接下来继续删除cluster信息srvctl config serverpoolcd /此处grid安装目录/bin#停止故障节点集群.\crsctl stop cluster -n rac1#查看资源状态

crsctl status res -tcrsctl check cluster -all

#删除应用层

crsctl delete node -n rac1crsctl stop resource ora.rac1.vip -fcrsctl delete resource ora.rac1.vip -f

如果vip还在,可以用如下命令删除vip

netsh interface ip delete address name="" addr=xx.xx.xx.xx更新删除后信息：

cd -d %ORACLE_HOME%\oui\bin.\setup -updateNodeList ORACLE_HOME=d:\app\11.2.0\grid  "CLUSTER_NODES={rac2}" CRS=TRUEolsnodes -i -t -s

--执行删除后检查

cluvfy stage -post nodedel -n rac1 -verbose
