Manual Oracle Uninstall

手动卸载oracle

A number of people have contacted me regarding problems uninstalling Oracle products. The two methods listed below should only be used as a last resort and will remove *all* Oracle software allowing a re-install. If you make any mistakes they can be quite destructive so be careful.

• Windows
• UNIX

Windows

In the past I've had many problems uninstalling all Oracle products from Windows systems. Here's my last resort method:

在之前我已经windows 系统上卸载oracle时碰到了很多问题以下是我最新整理的一些方法：

• Uninstall all Oracle components using the Oracle Universal Installer (OUI).
• 使用oui来卸载搜有组件
• Run regedit.exe and delete the HKEY_LOCAL_MACHINE/SOFTWARE/Oracle key. This contains registry entires for all Oracle products.
• 命令行下运行  regedit，在注册表中删除     HKEY_LOCAL_MACHINE/SOFTWARE/Oracle   键。这里包含了oracle 产品所有的注册记录。
• If you are running 64-bit Windows, you should also delete the HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/Oracle key if it exists.
• 64位的windows，需要删除    HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/Oracle  （如果有的话）
• Delete any references to Oracle services left behind in the following part of the registry (HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Ora*).
• 删除所有与oracle 服务相关的记录，也就是 (HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Ora*). 遗留下来的记录

          It should be pretty obvious which ones relate to Oracle.

           记录内容应当与oracle紧密相关。

 

• Reboot your machine.
• 重启服务器
• Delete the "C:\Oracle" directory, or whatever directory is your ORACLE_BASE.
• 删除$oracle_home 下所有的目录
• Delete the "C:\Program Files\Oracle" directory.
• 删除 "C:\Program Files\Oracle 所有内容
• If you are running 64-bit Wiindows, you should also delete the "C:\Program Files (x86)\Oracle" directory.
• 如果是64位的系统，需要额外删除   C:\Program Files (x86)\Oracle
• Empty the contents of your "C:\temp" directory.
• 清空   C:\temp
• Empty your recycle bin.
• 清空回收站

At this point your machine will be as clean of Oracle components as it can be without a complete OS reinstall.

Remember, manually editing your registry can be very destructive and force an OS reinstall so only do it as a last resort.

手工编辑注册表是一项非常危险的操作。

If some DLLs can't be deleted, try renaming them, the after a reboot delete them.

如果某些ddls不能被删除，可以尝试重命名他们，或者重启后再去删除它们。

UNIX

Uninstalling all products from UNIX is a lot more consistent. If you do need to resort to a manual uninstall you should do something like:

• Uninstall all Oracle components using the Oracle Universal Installer (OUI).
• 使用oui卸载oracle组件

• Stop any outstanding processes using the appropriate utilities.

• 停掉所有与oracle相关的进程

  # oemctl stop oms user/password
  # agentctl stop
  # lsnrctl stop

  Alternatively you can kill them using the kill -9 pid command as the root user

          你也可以使用kill -9 pid 来杀进程。.

• Delete the files and directories below the $ORACLE_HOME.

• 删除 $ORACLE_HOME. 目录

• # cd $ORACLE_HOME

• # rm -Rf *

• With the exception of the product directory, delete directories below the $ORACLE_BASE
• .一些特殊情况下，删除$ORACLE_BASE

  # cd $ORACLE_BASE
  # rm -Rf admin doc jre o*

• Delete the /etc/oratab file. If using 9iAS delete the /etc/emtab file also.
• 删除 /etc/oratab 文件，如果使用了9iAS 还需删除 /etc/emtab

• # rm /etc/oratab /etc/emtab

Hope this helps. Regards Tim...
