### Windows ###

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

*  Uninstall all Oracle components using the Oracle Universal Installer (OUI).
 *  Run `regedit.exe` and delete the `HKEY_LOCAL_MACHINE/SOFTWARE/Oracle` key. This contains registry entires for all Oracle products.
 *  If you are running 64-bit Windows, you should also delete the `HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/Oracle` key if it exists.
 *  Delete any references to Oracle services left behind in the following part of the registry (`HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Ora*`). It should be pretty obvious which ones relate to Oracle.
 *  Reboot your machine.
 *  Delete the "`C:\Oracle`" directory, or whatever directory is your ORACLE\_BASE.
 *  Delete the "`C:\Program Files\Oracle`" directory.
 *  If you are running 64-bit Wiindows, you should also delete the "`C:\Program Files (x86)\Oracle`" directory.
 *  Remove any Oracle-related subdirectories from the "C:\\ProgramData\\Microsoft\\Windows\\Start Menu\\Programs\\" directory.
 *  Empty the contents of your "`C:\temp`" directory.
 *  Empty your recycle bin.

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.

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

### 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).
 *  Stop any outstanding processes using the appropriate utilities.
    
        # oemctl stop oms user/password
        # agentctl stop
        # lsnrctl stop
    
    Alternatively you can kill them using the `kill -9 pid` command as the root user.
 *  Delete the files and directories below the $ORACLE\_HOME.
    
        # cd $ORACLE_HOME
        # rm -Rf *
 *  With the exception of the product directory, delete directories below the $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.
    
        # rm /etc/oratab /etc/emtab
