oracle数据库的卸载（附删除注册表代码）

一、写在开头
学完oracle后很长时间没用，后来在想用的时候却登不上了，也找不到具体原因是什么，所以一不做二不休，直接卸载了重新装一个，结果发现想卸载它也不是件容易的事，查了很多资料，把实操步骤写在这里，万一以后还用的上。

二、具体步骤
1、关闭服务
学过Oracle肯定知道服务，首先把和Oracle有关的服务全部关掉；

2、删除注册表
这一步非常麻烦，还好找到一个汇总文本。
将下面所有的代码写进一个文本文件里，然后把后缀名改为 .reg，然后保存，运行。当然，如果出了问题，本人可不负责，反正我用了的没出错。

3、删除相关文件

首先是你装Oracle的地方，直接删掉；
然后是C盘下的 C:\Program Files 和 C:\Program Files (x86) 里都有一个Oracle 删掉；
然后是 C:\ProgramData\Microsoft\Windows\Start Menu\Programs 里面的Oracle；
然后是C:\Windows\System32\config\systemprofile\Oracle。

我就删除了这些，最后重装成功了。

4、删除之前配置的Oracle相关环境变量

一共有三个：ORACLE_HOME、TNS_ADMIN、NLS_LANG。

三、写在最后
经历这4步之后再重装终于成功了。我的经历告诉我，装完Oracle之后没啥事不要动他的相关文件，否则再用的时候就很难受了。

如果有人看到希望能对你有所帮助，然后最好再点个赞，哈哈。
