oracle单库彻底删除干净的执行步骤

一、关闭数据库
[[email protected]]$sqlplus / as sysdba
SQL>shutdown immediate;

二、关监听
[[email protected]]$lsnrctl stop
三、删除oracle_base
我这里切换到了root
[[email protected]]#rm -rf /s01

三、清除残余文件
[[email protected]]# rm -f /usr/local/bin/dbhome
[[email protected]]# rm -f /usr/local/bin/oraenv
[[email protected]]# rm -f /usr/local/bin/coraenv
[[email protected]]# rm -f /etc/oratab
[[email protected]]# rm -f /etc/oraInst.loc
[[email protected]]# rm -f /opt/ORCL*

四、删除用户和组（如果要重建可以不删，省得再弄变量）
[[email protected]]#userdel -r oracle
[[email protected]]# groupdel oinstall
[[email protected]]# groupdel dba
