good.
Creating a Clean Machine
In rare situations, some users may want to correct serious system problems
by completely removing Oracle products from their system. 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. Complete the following steps to create a
Clean Machine.
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 (at the command prompt, type 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;G: \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 from <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 the 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 HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\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 the Windows NT
Explorer or from 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.
