一,节点环境
[root@node1 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.0.194 node2 192.168.0.193 node1 192.168.0.183 node1vip 192.168.0.182 node2vip 172.168.0.194 node2prv 172.168.0.193 node1prv 192.168.0.176 dbscan 192.168.0.16 standby
二,操作实例
01,dbca 删除节点host02
登入Oracle 用户运行dbca-->进行删除数据库-->delete databases 下一步
!!!----------------------------注意--------------------------!!!
选择数据库请认真核对.确定数据安全性!!,删除前再三思考!!选项是英文,请看懂英文再选择!!
输入用户sys,密码123456,具体根据自己的来填写
为啥到这一步出问题了呢,因为我在node2节点删除node2节点,自己删自己当然不允许啦,现在我换个节点node1操作把
到了node1删除的时候会发现自动选择node2节点
node1 上查看节点是否存在
----------------------------------------------------
三,清理
01,发现节点还在,资源也还在

02,停掉监听
格式: srvctl disable listener -l listener_name -n name_of_node_to_delete srvctl stop listener -l listener_name -n name_of_node_to_delete 操作: srvctl disable listener -l listener -n node2 srvctl stop listener -l listener -n node2

03,删除Oracle software
操作如下:
