1 如果有service则定位到好的节点，否则问题节点无法删除，我这里没有就不演示了，给出例子
[oracle@*Node1* ~]$ srvctl modify service -d *RAC DB* -s *RAC SERVICE1* -n -i *RAC INST 1* -f
重构RDBMS实例，删除问题节点实例，这里由于直接删除安装文件，重装系统，找个步骤也没有
正常使用dbca删除

因为无法使用DBCA，下面直接删除集群记录的实例资源，删除数据库实例
[root@rac1 bin]# srvctl remove instance -db prod -i prod2
Remove instance from the database prod? (y/[n]) y

3 从RAC cluster 删除节点
[oracle@rac1 ~]$ cd $ORACLE_HOME/oui/bin
[oracle@rac1 bin]$ echo $ORACLE_HOME
/oracle/db/product/12.2
[oracle@rac1 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=/oracle/db/product/12.2 "CLUSTER_NODES={rac1}"
Starting Oracle Universal Installer...

Checking swap space: must be greater than 500 MB. Actual 33654 MB Passed
The inventory pointer is located at /etc/oraInst.loc
'UpdateNodeList' was successful.

4 从Grid Cluster删除节点
[root@rac1 ~]# srvctl stop vip -i rac2
[root@rac1 ~]# srvctl remove vip -i rac2 -f
[root@rac1 ~]# olsnodes -s -t
rac1 Active Unpinned
rac2 Inactive Unpinned
[root@rac1 ~]# crsctl delete node -n rac2
CRS-4661: Node rac2 successfully deleted.

检查当前集群资源i情况
[root@rac1 ~]# crsctl stat res -t

5 清理GI inventory记录的节点信息

[grid@rac1 asm]$ cd $ORACLE_HOME/oui/bin
[grid@rac1 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=/oracle/asm "CLUSTER_NODES={rac1}" CRS=TRUE -silent
Starting Oracle Universal Installer...

验证
[root@rac1 ~]# olsnodes -s -t
rac1 Active Unpinned


6 安装前环境检查
[grid@rac1 ~]$ cd $ORACLE_HOME
[grid@rac1 asm]$ cd bin
[grid@rac1 bin]$ ls -lrt clu*

如果是先决条件不具备，要看日志提示，其中critical的必须满足，其实再 cluvfy stage -pre测试阶段已经总结了failed部分，只是没有标注ignore或者critical。
解决上述问题
继续执行添加节点 ，增加集群节点添加参数 以忽略所有检查失败选项，前提是确认失败项目不会影响安装（比如我们检查发现veritas共享盘的共享性问题，这个问题Oracle定位为Critical）

20201118-dbca图形添加实例失败，undo空间创建问题，日志组问题，下面测试解决方法
1 删除节点2的集群日志（这个操作在srvctl手工增加实例会有自动删除操作，图形也会有这个操作，这里模拟节点异常删除如rm按照目录，重装操作系统等），如果正常删除节点，这个步骤应该是不需要的。
