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 t hat 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.
