Introduction
------------
Removing or deinstalling Oracle software from an 95/98/NT operating system
requires several steps to completely creating a 'clean' machine. This
document explains what must be done to remove all Oracle software from the
system.
Warning
-------
1) Backup
Be careful, because these steps remove all Oracle software, Oracle services,
and Oracle registry entries from the system.
So it is advisable that you first perform a backup, if required, of
certain files like:
SQL*Nnet configuration files
Database files
Self-written scripts
that are stored under the oracle home directory, etc.
2) The following procedures require the editing of Windows registry, which is a
potentially dangerous operation. There is no undo option in the Registry
Editor.

A. 32-bit on Windows NT
-----------------------
1. Ensure that you are logged in as a user with Administrator privileges.
2. Stop all Oracle-related services and all Oracle programs.
3. Remove the database services via the oradim command. This can be
done via ORADIMXX -DELETE -SID <SID> or via the 'SC' tool of the
resource kit.
For a full explanation on using the ORADIM command, see [NOTE:61621.1].
As from 8.1.6, the method for deinstalling is to first run Net8CA
in Deinstall mode, then run DBCA to delete a database, then run OUI
to deinstall the products. At this point, all services should be
removed.
4. Start the ODBC administrator applet, if installed, and remove any
Oracle DSN definitions.
5. Remove the Oracle software via the Oracle installer or the
Universal Installer (8.1.5 and onwards). Make sure that all
services related to Oracle are stopped first.
Note that you cannot remove the installer itself.
If Legato Storage Manager is installed on the system, then remove it via
the uninstaller executable that is shipped with Legato.
Start->Programs->Networker->Uninstall Networker
Caution: If Legato Storage Manager was installed independently of
Oracle, DO NOT REMOVE LSM, because your system's backup
environment may be adversely affected.
6. Start the Event Viewer, Log->Application, and clean up the
application logs for Oracle.
7. Start the registry editor. This can be done via regedit or
regedt32.
a) If the Oracle Universal Installer (OUI) was used, go to
HKEY_LOCAL_MACHINE\Software\Oracle and write down the value of
the INST_LOC variable. This shows you where the OUI
software is installed. This can then be used to remove the OUI
from the machine afterwards.
b) Go to HKEY_LOCAL_MACHINE\Software and remove the ORACLE key,
look into the ODBC key for any 'leftovers' of Oracle. If they
exist, then remove them as well.
c) Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and
verify that all services that start with 'Oracle' are removed.
If this is not the case, then remove the services starting with
'Oracle' (database related) and the ones that start with
'OraWeb' (Oracle Application Server related).
No entries will not be removed from the services dialog box
until you reboot.
d) Go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\
Application and look for keys that start with 'Oracle'.
Normally, they should have been removed in Step 5.
e) Go to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
\Uninstall
and remove all entries related to Oracle
Typical entries to found there are:
Oracle JInitiator 1.1.x.x
f) Close the registry editor.
8. Remove any Oracle related .INI files that may exist in the Windows
NT Boot directory. The Windows NT boot directory may be found by
entering "SET WINDIR" from a command prompt.
Typical Oracle .INI files include ORADIM73.INI, ORADIM80.INI,
ORACLE.INI, ORAODBC.INI
9. Go to Start->Settings->control Panel->System->Environment.
* Select in the 'System Variables' window the PATH variable and
remove the %ORACLE_HOME%\BIN directory. If JRE was installed by
Oracle, then remove the JRE path as well.
(For example: ...;C:\Orant\Bin;C:\Program Files\Oracle\jre\1.1.7\bin;...)
* Check the �User Variables for user xxx� section also for Oracle
entries to remove.
* Check as well the �System Variables� as �User Variables for user
xxx� windows for Oracle variable to remove: typical entries could
be: ORACLE_SID, TNS_ADMIN, �
10. Remove any icons and references from the start menu. They are
listed into the C:\Winnt\Profiles\All Users\Start Menu\Programs
directory.
Normally, they should be removed by the Oracle Installer in Step 4.
11. Remove the %ORACLE_HOME% directory from the machine, either by
using the Windows NT Explorer or from the command prompt.
12. If the Oracle products were installed via the Oracle Universal
Installer, then remove this also from the system. By default, it is
installed under the Oracle directory in C:\Program Files, although
you could have specified an alternative directory when
you installed the Oracle Universal Installer (OUI). In that case,
look at the INST_LOC parameter you have noted down in Step 6a.
13. Reboot your computer.
B. 32-bit on Win95/Win98
------------------------
1. Stop all Oracle programs.
2. Start the ODBC administrator applet, if installed, and remove any
Oracle DSN definitions.
3. Remove the Oracle software via the Oracle installer or the
Universal Installer (8.1.5 and onwards). Note that you cannot remove
the installer itself.
If Legato Storage Manager is installed on the system, then remove it via
the uninstaller executable that is shipped with Legato.
Start->Programs->Networker->Uninstall Networker
Caution: If Legato Storage Manager was installed independently of
Oracle, then DO NOT REMOVE LSM, because your system's backup
environment may be adversely affected.
4. Start the registry editor. This can be done via regedit or
regedt32.
a) If the Oracle Universal Installer (OUI) was used, go to
HKEY_LOCAL_MACHINE\Software\Oracle and write down the value of
the INST_LOC variable. This is showing you where the OUI
software is installed. This can then be used to remove the OUI
from the machine afterwards.
b) Go to HKEY_LOCAL_MACHINE\Software and remove the ORACLE key,
look into the ODBC key for any 'leftovers' of Oracle, if they
exist remove them as well.
c) Go to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\
CurrentVersion\Uninstall and remove all entries related to
Oracle.
5. Close the registry editor.
6. Edit your AUTOEXEC.BAT file and remove the %ORACLE_HOME%\bin and
JRE paths from the PATH.
(For example: ...;C:\Orant\Bin;C:\Program Files\Oracle\jre\1.1.7\bin;...)
Check if any Oracle variables are set in the AUTOEXEC.BAT. If there are,
then remove them.
7. Remove any icons and references from the Start menu. They are
listed in the C:\Windows\Start Menu\Programs directory via Windows
Explorer. These are not always removed by the Oracle installer in
Step 2.
8. Remove the %ORACLE_HOME% directory from the machine, either by
using the Windows Explorer or from the command prompt.
9. If the Oracle products were installed via the Oracle Universal
Installer, remove this also from the system. By default, it is
installed under the Oracle directory in C:\Program Files, although
you could have specified an alternative directory when
you installed the Oracle Universal Installer (OUI). In that case,
look at the INST_LOC parameter you have noted down in Step 3a.
10. Remove any Oracle-related .INI files that may exist in the Windows
directory. The Windows may be found by entering "echo %WINDIR%"
from a command prompt.
Typical Oracle .INI files include ORADIM73.INI, ORADIM80.INI,
ORACLE.INI, ORAODBC.INI
11. Reboot you computer.
C. 16-bit
---------
The default Oracle Home for Windows 3.X is orawin.
1. If the database is running, then shut it down.
2. Deinstall all Oracle products with the Oracle Installer.
a) Run orainst.exe from your Oracle Home. The Oracle Software
Asset Manager window is displayed.
b) Select all of the Oracle products that are listed in the
right window pane.
c) Click the [REMOVE] button.
3. Delete your ORACLE_HOME directory.
4. Use your favorite text editor and edit win.ini.
a) Locate the ora_config parameter.
Remove the file that ora_config points to.
b) Delete all references to Oracle from the win.ini file.

Here are instructions that were once posted.
I haven't tried it myself, but at quick glance, it looks right.

This procedure has worked really well for me. both NT and Win9x versions
here.
=======
In rare (yeah, right) situations, some users may want to correct serious
system problems by completely removing Oracle products from their systems.
This is not recommended as an easy way to fix problems, especially common
ones. Only create a Clean Machine as a last resort and only if you want to
remove all Oracle products from your system.
� Note: The following Clean Machine instructions assume an OFA (Optimal
Flexible Architecture) structure.
� Warning : This will remove all Oracle products, Oracle services and
Oracle registry entries from your computer.
On Windows NT:
1) Ensure you are logged in as a user with Administrator privileges
2) Using regedit go to HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE and delete the
ORACLE key.
3) Delete HKEY_LOCAL_MACHINE\SOFTWARE\odbc
4) Open HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and remove all
keys under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services that begin
with ORACLE
5) Open
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application
and remove all keys under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application
that begin with ORACLE.
6) Close regedit
7) From the Control Panel, open System
8) If JRE was installed by Oracle, remove the %ORACLE_HOME%\BIN path and
the JRE path. For example, you may see a path similar to this one:
C:\ORACLE\ORA81\BIN; C:\Program Files\Oracle\jre\1.1.7\bin. Go to Start >
Control Panel>System Environment tab. Click on the system variable path
and modify the path.
9) Delete Icons form <system_drive>:\Winnt\Profiles\All Users\Start
Menu\Programs\Oracle -<HOME> and <system_drive>:\Winnt\Profiles\All
Users\Start Menu\Programs\Oracle Installation Products. Where <HOME> is
the previous HOME name.
10) Delete <system_drive>:\Program Files\Oracle (from Windows NT Explorer
or from the command prompt)
11) Reboot your computer.
12) Delete all ORACLE_BASE directories. (you can find the Oracle Homes
listed in KEY_LOCAL_MACHINE\SOFTWARE\ORACLE_HOMES).
On Windows 95 and Windows 98:
1) In regedit, go to HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE.
2) Delete the ORACLE key.
3) Delete HKEY_LOCAL_MACHINE\SOFTWARE\odbc
4) Edit your AUTOEXEC.BAT file and remove your %ORACLE_HOME%\bin and JRE
paths from the path setting
5) From the Windows Explorer or from the command prompt; delete the Oracle
directory (Oracle Base)
6) Delete <system_drive>:\Program Files\Oracle (from Windows Explorer or
the command prompt)
7) Delete Icons from <system_drive>:\Windows\Start Menu\Programs\Oracle -
<HOME> and <system_drive>:\Windows\Start Menu\Programs\Oracle Installation
Products where <HOME> is the previous HOME name.
8) Reboot your computer.
