一、环境描述
周五要给客户讲11g OCP,提前做一个删除数据库测试,记录如下,知识点大家自己get吧~。工作和讲课真的是有很大区别,要对各种知识点知其然,还要知其所以然,理论要求高的多。加油!
二、具体操作
删除数据库主要有两种方法
1、使用DBCA
2、使用DROP DATABASE
下面使用第二种方法删除数据库,操作过程如下:
[root@11g-ocp ~]# su - oracle
<11g-ocp:orcl:/home/oracle>$export ORACLE_SID=orcl12345678
<11g-ocp:orcl12345678:/home/oracle>$sqlplus / as sysdba

大家可以考虑到底删除了哪些文件,还要哪些文件没有被删除,为什么要mount状态下删除呢?可以给我留言~
