This procedure cleans a Windows system if uninstallation
of WebSphere Process Server fails. After running the uninstallation
program, these manual steps remove registry entries that can prevent
you from reinstalling the product into the original directory. If
you are not planning to reinstall, do not perform this task.
Before you begin
Before performing this procedure, ensure you
have uninstalled WebSphere Process Server using the Uninstallation Wizard
or silently, and that the procedure was not completely successful.
If the procedure was successful, you do not need to perform this
task.
Determine the install_root directory for the
product so that you remove the correct product and produce a clean
system.
Default directories are shown in Table 1:
Table 1. Planning table for
identifying actual location of product installationIdentifier |
Default directory location |
Actual location |
install_root |
C:\Program Files\IBM\WebSphere\ProcServer or C:\Program Files\IBM\WebSphere\AppServer |
|
profile_root |
C:\Program Files\IBM\WebSphere\ProcServer\profiles
\profile_name or C:\Program Files\IBM\WebSphere\AppServer\profiles
\profile_name A character space was added to these
entries to enable them to fit in the table cell. The actual entries
do not include a character space.

On Windows platforms: If
you move either installation root directory, move it to a directory
with a shorter path name. Windows platforms have a length restriction
of 258 characters for a command. A problem can occur that prevents
the successful creation of a profile when either path is too long.
The maximum length for the install_root directory is 60 characters.
The maximum length for the profile_root directory is 80 characters.
The
Installation Wizard and the Profile Wizard let you specify your
own locations for installation root directories. Examine the following
files to determine the actual locations:
- The %USERPROFILE%\.WBIRegistry file
identifies the installation root for all installed WebSphere Process Server
products; the %USERPROFILE%\.WASRegistry file, for all
WebSphere Application Server products.
- The install_root\logs\wasprofile\wasprofile_create_profile_name.log file
for each created profile identifies the installation location in
the stanza with the <method>invokeWSProfile</method> tag.
Uninstalling
the product leaves the
profile_root directory, including
the
profile_root\logs directory with the
pcatLog<timestamp>.txt file,
where
profile_root represents the installation location of
the profile. It leaves the
install_root\logs directory
as well.
Why and when to perform this task
Reinstalling the product into a new directory when files
remain from a previous installation can create a coexistence scenario.
However, you can delete all files and registry entries to completely
remove WebSphere Process Server. A clean system lets you reinstall
the product into the original directory without coexistence.
Important: Throughout this procedure, steps address
removing artifacts left after uninstallation of both WebSphere Process
Server and WebSphere Application Server or WebSphere Application
Server Network Deployment. The WebSphere Application Server product
addressed is assumed to be the one underlying the installation of
WebSphere Process Server.
Perform the following procedure
to produce a clean system.
Steps for this task
- Log on with a user ID that belongs to the Administrator
group.
- Verify that you have an Emergency Recovery Disk. Instructions
for creating this disk are in the Windows help documentation.
This step is a safeguard. This procedure does not require
the recovery disk.
- Use the regback.exe program from the Windows
Resource Kit to back up the registry.
This step is a safeguard. This procedure does not require
the backup copy of the registry.
- Delete product registry entries for the WebSphere Process
Server and WebSphere Application Server products that you uninstalled.
Invoke regedit.exe from a command prompt, to edit
the Windows system registry.
CAUTION:
Handle the
Registry with care. You can easily make a mistake while using the
registry editor to view and edit registry contents. The editor does
not warn you of editing errors, which can be extremely dangerous. A
corrupt registry can disrupt your system to the point where your
only option is to reinstall the Windows operating system.
- Use Ctrl-F to search for all instances
of WebSphere, to determine whether you should delete
each entry. You might not be able to remove all of the entries related
to WebSphere Process Server and WebSphere Application Server, which
is not a problem.
- Expand and select keys related to WebSphere Process
Server and WebSphere Application Server products.
Delete the following keys if present for the WebSphere
Application Server product:
- HKEY_CURRENT_USER\
Software\ Microsoft\ Windows\ Currentversion\ Explorer\ MenuOrder\ Start
Menu\ Programs\ IBM WebSphere\ Application Server Network Deployment
v6
- HKEY_LOCAL_MACHINE\ Software\IBM\ WebSphere Application Server
Network Deployment\ 6.0.0.0
- HKEY_LOCAL_MACHINE\ Software\ IBM\ Web server Plug-ins for IBM
WebSphere Application Server\ 6.0.0.0
Delete the
following keys if present for the WebSphere Process Server product:
- HKEY_CURRENT_USER\ Software\ Microsoft\ Windows\
Currentversion\ Explorer\ MenuOrder\ Start Menu\ Programs\ IBM WebSphere\Process
Server 6.0
- HKEY_LOCAL_MACHINE\Software\IBM\WebSphere Process Server\6.0.0.0
- Select Edit > Delete from the menu bar for
each related key.
- Select Yes when asked to confirm deletion of
the key.
- Select Registry > Exit from the menu bar when
you are finished.
- Delete any profile directories that are not located in
the installation root (install_root) directory.
To determine the locations of profile directories, first
use the wasprofile -listProfiles command to display
profile names. Then, to determine where profile directories are
located, use the wasprofile -getPath -profileName profile_name command,
where profile_name is the name
of the profile corresponding to a given directory.
- Delete the installation root directory for the product
that you uninstalled.
- Open a Windows Explorer window and browse to the C:\Documents
and Settings\All Users\Start Menu\Programs\IBM WebSphere directory.
If you have only one installation of WebSphere Application
Server, delete the following folder if it is present:
Application Server v6
If you have only one installation of WebSphere Application
Server Network Deployment, delete the following folder if it is
present:
Application Server Network Deployment v6
If you have only one installation of WebSphere Process
Server, delete the following folder if it is present:
Process Server 6.0
If you have multiple versions of WebSphere Application
Server or
WebSphere Process Server installed, the folder names will
be appended with a number, for example,
Application Server
Network Deployment v6 (2) or
Process Server 6.0
(2). In this case, you can use the following procedure to
determine which folder(s) to delete:
- Open C:\Documents
and Settings\All Users\Start Menu\Programs\IBM WebSphere in
Windows Explorer.
- Open the Application Server v6 or Application
Server Network Deployment v6 subfolder, if one exists in
the IBM WebSphere folder.
- Right-click the First steps subfolder and select
Properties, then select the Shortcut tab.
- Examine the Target property and determine if the Target directory
points to the WebSphere Application Server installation that failed
to uninstall. If that is the case, delete the Application
Server v6 or Application Server Network Deployment
v6 folder.
- Repeat steps b through d, but this time for step b start with
the Process Server 6.0 subfolder, and for step
d, determine if the Target directory points to the WebSphere Process
Server installation that failed to install.
- Repeat steps b through e for each additional set of folders
(for example, Application Server Network Deployment v6 (2) or Process
Server 6.0 (2)).
- Delete the %WINDIR%\IsUninst.exe file.
- Edit the vpd.properties file to remove
the entries for WebSphere Process Server and WebSphere Application
Server or WebSphere Application Server Network Deployment.
The file is located in the installation directory of the
operating system, such as the
C:\WINNT or C:\Windows directory.
Remove all entries for the installation of
WebSphere Process Server
that you have uninstalled. Each
WebSphere Process Server entry starts
with the characters
WSE, followed by numbers representing
the release number, and on the same line will have the
install_root path
corresponding to the installation you have uninstalled. (Each entry
is on a single line if the file is displayed in a text editor with
word wrap turned off.) For example, the line
WSEAA60BPC|6|0|0|0|6.0.0.0|1=Bpc|BPC||IBM||6.0.0.0
|C:\Program Files\IBM\WebSphere\ProcServer|0|0|1|WSEAA60|6|0|0|0|6.0.0.0|1|0
|true|true|3|WSEAA60BPC|6|0|0|0|6.0.0.0|1
corresponds to the Business Process Choreographer component
(indicated by
BPC in the example), for an installation
that was installed in the directory
C:\Program Files\IBM\WebSphere\ProcServer.
Note: This text appears in several lines in this document
for formatting purposes but would be a single line in the vpd.properties file.
Each WebSphere Application Server or WebSphere Application Server
Network Deployment entry in the vpd.properties file
has a similar format. For information about these entries to help
you determine which to delete, and for more information about the vpd.properties file,
refer to the WebSphere Application Server Network
Deployment, version 6.0 information center.
Do not delete or rename the vpd.properties file
because the InstallShield for MultiPlatforms (ISMP) program uses
it for other products that it installs. If the WebSphere Process
Server or WebSphere Application Server product that you are uninstalling
is the only product with entries in the vpd.properties file,
you can delete this file.
- Edit the .WBIRegistry and .WASRegistry files.
The location of these files is the home directory of the
user ID from which the product was installed.
The .WBIRegistry file contains a one-line entry for
each WebSphere Process Server product installation; the .WASRegistry file,
for each WebSphere Application Server product installation.
You can delete these files if there is just one line in each
that identifies the product that you removed. Otherwise, use a flat-file
editor to remove the line that identifies the installation root
directory of the product that you removed. Leave the other lines
intact. Do not delete the .WBIRegistry and .WASRegistry files
unless you removed all of the installations listed in the files.
- Restart your server if a prompt is displayed that directs
you to restart.
Result
This procedure results in having a clean system. You
can reinstall into the same directories now. A clean system has
no trace of a previously deleted installation.
What to do next
After you have cleaned your system, go to Installing the product to choose an installation procedure.
