oracle單庫徹底刪除干凈的方法

    一、關(guān)閉數(shù)據(jù)庫
    [oracle@RHEL5]$sqlplus / as sysdba
    SQL>shutdown immediate;
    二、關(guān)監(jiān)聽
    [oracle@RHEL5]$lsnrctl stop
    三、刪除oracle_base
    我這里切換到了root
    [root@RHEL5]#rm -rf /s01
    三、清除殘余文件
    [root@RHEL5]# rm -f /usr/local/bin/dbhome
    [root@RHEL5]# rm -f /usr/local/bin/oraenv
    [root@RHEL5]# rm -f /usr/local/bin/coraenv
    [root@RHEL5]# rm -f /etc/oratab
    [root@RHEL5]# rm -f /etc/oraInst.loc
    四、刪除用戶和組(如果要重建可以不刪，省得再弄變量)
    [root@RHEL5]#userdel -r oracle
    [root@RHEL5]# groupdel oinstall
    [root@RHEL5]# groupdel dba
