This procedure cleans a Windows system if uninstallation of WebSphere ESB 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 ESB 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:

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 ESB 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 ESB.
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 ESB and WebSphere Application Server Network
Deployment. The WebSphere Application Server product
addressed is assumed to be the one underlying the installation of WebSphere ESB.
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 ESB 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 ESB and WebSphere Application Server, which
is not a problem.
- Expand and select keys related to WebSphere ESB 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 ESB product:
- HKEY_CURRENT_USER\ Software\ Microsoft\ Windows\ Currentversion\ Explorer\
MenuOrder\ Start Menu\ Programs\ IBM WebSphere\Enterprise Service Bus 6.0
- HKEY_LOCAL_MACHINE\Software\IBM\WebSphere Enterprise Service Bus\6.0.1.0
- HKEY_LOCAL_MACHINE\Software\IBM\WebSphere Process Server\6.0.1.0
- 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 manageprofile
-listProfiles command to display profile names. Then, to determine
where profile directories are located, use the manageprofile -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 Network
Deployment, delete the following folder if it is present:
Application Server Network Deployment v6
If you have only one installation of
WebSphere ESB,
delete the following folder if it is present:
Enterprise Service Bus 6.0
If you have multiple versions of
WebSphere Application Server or
WebSphere ESB 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 ESB 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 ESB and 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 ESB that
you have uninstalled. Each WebSphere ESB 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.)
Each 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 ESB 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 WebSphere ESB to choose an installation procedure.
