有时候如果删除oracle不彻底的话，那么下次再安装的时候会有很多麻烦的事发生，现在让批处理来帮你删除oracle吧，保证给你删除的干干净净，代码如下：
@echo off&&setlocal enabledelayedexpansion 
color 0a 
:start 
for /f "tokens=2 delims==" %%a in ('path') do ( 
        set "str=%%a" 
        set str=!str: =+! 
        for %%i in (!str!) do ( 
                set "var=%%i" 
                set var=!var:+= ! 
                echo !var!>>change.txt 
  for /f "delims=" %%i in ('findstr "oracle" change.txt') do set var=%%i 
        ) 
         
)
