Oracle删库跑路

Posted 2021-01-02

--10g R2
startup mount exclusive restrict;
alter system enable restricted session;
drop database;

--11g
startup mount exclusive;
alter system enable restricted session;
drop database;

--RAC 12.1.0.2.0删库 
1.先停止所有节点实例
2.在其中一节点操作,先关闭rac模式
startup nomount;
alter system set CLUSTER_DATABASE=FALSE scope=spfile;
shutdown immediate;
3.启动mount restric模式
startup mount restrict;
4.删除数据库
drop database;
