从window 7、Xp卸载Oracle 10g
第1步：打开开始菜单，在程序文件中查找oracle – oraDb10g_home文件夹，然后选择oracle安装产品 – > 通用安装程序。
第2步：选择Deinstall Product，将弹出新窗口，选中复选框oracleDb10g_home1，如下所示。 单击删除按钮。 这将删除预言机。
第3步：从Regedit中删除注册文件，以彻底删除oracle 10g。 运行注册表。
如果卸载后退出，请删除以下键。
第 4 步：现在删除安装软件的文件夹。 默认情况下，它安装在 c 驱动器中，名称为 C:\oracle，来自 C:\programs files\oracle。
因此，通过成功执行此步骤，Oracle 10g 已被完全删除。 如果您在删除或卸载该程序（oracle）时遇到任何问题，请在下面发表评论，我们会予以关注。
Uninstall Oracle 10g from window 7, Xp
step 1 : Open up the start menu and in program files look for oracle – oraDb10g_home folder, and select oracle installation products – > Universal Installer.
step 2 : Select Deinstall Product, which will pop up new window , select check box oracleDb10g_home1 as shown below. Click on remove button. This will remove oracle.
step 3 : Remove the registration file from Regedit, in order to remove oracle 10g completely. Run Regedit.
Delete the following keys if it exits after the un-installation.
step 4 : Now delete the folder where you have installed the software. By default, it is installed in c drive as C:\oracle and from C:\programs files\oracle.
Hence by doing this steps successfully, Oracle 10g is removed completely. If you are having any problem in removing or uninstalling the program,(oracle ) then do comment below, we will look on that.
VM环境使用技巧最好：不用担心卸载。 只需安装一个完整的 Oracle 环境，并在成功运行一次后：winrar VM ...再次损坏 Oracle 主目录后：只需删除当前 VM 并解压缩备份
The tips for using a VM enviroment is the best: no worries about deinstalling. Just install a complete Oracle enviroment and after one succesfull run: winrar the VM ... after corrupting the Oracle home once again: just delete the current VM and unrar the backup
这看起来太简单了，但在 Windows 中，我可以通过进入“Settings”>“卸载 Oracle”。 应用程序和功能找到 Oracle 数据库，单击它，然后
卸载。 我什至不需要密码。This seems way too simple, but in Windows I was able to uninstall Oracle by going into
Settings > Apps and Featuresfinding the Oracle database clicking it and thenuninstall. I didn't even need a password.假设您使用的是 unix 类型操作系统，并且您使用名为 oracle 的帐户正确安装了它...
find / -user oracle -exec rm -fr {} \;
话虽如此，这必须以 root 身份完成，并且您最好不要介意丢失属于 oracle 的任何和所有文件。 此方法不会...无法恢复。
Assuming a unix type OS and that you properly installed it using an account named oracle...
find / -user oracle -exec rm -fr {} \;
That having been said, this must be done as root and you had better not mind loss of any and all files that belong to oracle. There will be no... NO recovery from this method.
从 Windows 计算机中删除 Oracle 所有内容的六步过程：
A. 删除 Oracle 服务：
在注册表中，转到
\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
并删除以“Oracle”开头的所有内容
B. 从注册表中删除其他 Oracle 内容：
转到
\HKEY_LOCAL_MACHINE\SOFTWARE\并删除 ORACLEC. 重新启动
D. 从安装目录中删除所有 Oracle 软件
E. 删除 Oracle 软件清单：
删除目录
C:\Program Files\Oracle。 无论您在何处安装 Oracle 软件，您都必须执行此操作 - Oracle 安装程序会自动在此处写入信息。F. 从“开始”菜单中删除所有快捷方式。
G. 从 PATH 环境变量中删除Oracle 目录。
为了简化将来的清理工作，我强烈建议您在一台或多台虚拟机中安装 Oracle 产品。
The six-step process to remove all things Oracle from a Windows machine:
A. Delete the Oracle services:
In the registry, go to
\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servicesand delete everything that starts with "Oracle"
B. Remove other Oracle stuff from the registry:
Go to
\HKEY_LOCAL_MACHINE\SOFTWARE\and delete the key ORACLEC. Reboot
D. Delete all the Oracle software from the directories where you installed it
E. Delete the Oracle software inventory:
Delete the directory
C:\Program Files\Oracle. You must do this no matter where you installed your Oracle software - the Oracle installer automatically writes information here.F. Delete all shortcuts from your Start menu.
G. Remove the Oracle directories from PATH Environment Variable.
To simplify cleanup in the future, I'd strongly recommend you install your Oracle products in one or more virtual machines.
看一下：
http://www.oracle-base.com/articles /misc/ManualOracleUninstall.php
基本上，它归结为：
使用安装程序删除所有可以删除的内容。
从注册表中删除 Oracle 密钥。
从您的计算机中删除 Oracle 目录。
（当然）根据需要进行必要的重新启动;-)
Have a look at:
http://www.oracle-base.com/articles/misc/ManualOracleUninstall.php
Basically, it comes down to:
Remove all you can with the installer.
Remove Oracle keys from the registry.
Remove the Oracle directories from your computer.
With (of course) the requisite reboots thrown in as required ;-)
值得注意的是，有一个官方的 Oracle 独立卸载程序： https://docs.oracle.com/cd/E11882_01/install.112/e47689/remove_oracle_sw.htm#LADBI1332，我刚刚用来卸载Oracle 11客户端。 这不一定比本页最上面的建议更好或更容易使用，但它是“官方的”。
需要注意的一件事 - 如果您使用官方卸载程序，它不喜欢临时文件夹中有空格。 因此，如果您将其设置为“Documents and Settings...\temp”，它将失败。 首先使用控制面板环境设置按钮设置 TEMP 文件夹。
It's worth noting that there is an official Oracle standalone deinstaller: https://docs.oracle.com/cd/E11882_01/install.112/e47689/remove_oracle_sw.htm#LADBI1332, which I just used to uninstall Oracle 11 client. This is not necessarily better or easier to use than the top suggestion on this page, but it is "official".
One thing to note - if you use the official deinstaller, it does not like the temp folder to have spaces in it. So if you have it set to "Documents and Settings...\temp" it will fail. Use the control panel environment settings button to SET the TEMP folder first.
