Windows下手动完全卸载Oracle使用,Oracle自带的Universal Installer卸载存在两个问题:速度慢;不干净;不完全;还有一些注册表

使用Oracle自带的Universal Installer卸载存在两个问题:

1)  速度慢;

2) 不干净;不完全;还有一些注册表残留,会影响到后来的安装。

所以,推荐使用手工卸载Oracle。

1.【win+R】->【services.msc】,关闭oracle所有的服务。

2. 打开注册表【win+R】->【regedit】。打开路径: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\  删除该路径下的所有以oracle开始的服务名称,这个键        是标识Oracle在windows下注册的各种服务!

3.打开注册表,找到路径: HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE 删除该oracle目录,该目录下注册着Oracle数据库的软件安装信息。

4.删除注册的oracle事件日志,打开注册表 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application 删除注册表的以oracle开头的所有项目。

5.删除环境变量path中关于oracle的内容。 鼠标右键右单击“我的电脑-->属性-->高级-->环境变量-->PATH 变量。 删除Oracle在该值中的内容。注意:path中记录着一堆操作系统      的目录,在windows中各个目录之间使用分号(;)隔开的,删除时注意。 建议:删除PATH环境变量中关于Oracle的值时,将该值全部拷贝到文本编辑器中,找到对应的          Oracle的值,删除后,,再拷贝修改的串,粘贴到PATH环境变量中,这样相对而言比较安全。

6.重新启动操作系统。

7.重启操作系统后各种Oracle相关的进程都不会加载了。这时删除Oracle_Home下的所有数据。(Oracle_Home指Oracle程序的安装目录)

8.删除C:\Program Files下oracle目录。  (该目录视Oracle安装所在路径而定)

9.删除开始菜单下oracle项,如:  C:\Documents and Settings\All Users\「开始」菜单\程序\Oracle - Ora10g  不同的安装这个目录稍有不同。  如果不删除开始菜单下的Oracle相    关菜单目录,没关系,这个不影响再次安装Oracle.当再次安装Oracle时,该菜单会被替换。

至此,Windows平台下Oracle就彻底完全卸载了。
