This procedure cleans an AIX 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 |
/usr/IBM/WebSphere/ProcServer or /usr/IBM/WebSphere/AppServer |
|
profile_root |
/usr/IBM/WebSphere/ProcServer/profiles
/profile_name or /usr/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.

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 ~/.WBIRegistry file identifies the
installation root for all installed WebSphere Process Server products;
the ~/.WASRegistry file, for all WebSphere Application
Server products. These files are located in the home directory of
the user ID from which the product was installed.
- 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 as root.
- Use the kill command to kill all Java processes
that are running.
If you are running Java processes that are not related
to
WebSphere Process Server or WebSphere Application Server products
and it is not possible to stop them, stop all WebSphere Process
Server and WebSphere Application Server product-related processes.
Use the following command to determine all processes that are running:
ps -ef | grep java
Stop all
WebSphere Process Server and WebSphere Application
Server product-related processes with the
kill -9 java_pid_1 java_pid_2...java_pid_n command.
- List WebSphere Process Server and WebSphere Application
Server components that are installed.
Type the following command to search for related packages:
lslpp -l | grep -i WS
To narrow your query to search for
WebSphere Process Server packages
only, type the following command:
lslpp -l | grep -i WSEAA60
WebSphere Process Server package names have a prefix of WSE and
a suffix of 60. WebSphere Application Server Network Deployment,
version 6.0 package names have a prefix of WSB or WSP and a suffix
of 60. Do not remove packages for WebSphere Process Server and WebSphere
Application Server products that you did not uninstall.
- Use the geninstall command to remove registry
information for each component that is displayed in the list (for products
that you uninstalled).
For example, issue the following command to show packages
with a prefix of WSE:
lslpp -l | grep -i WSE
The system displays the list of matching packages.
Issue the following command to remove a registry entry (for example,
WSEAA60WBICoreComponent-6.0-0):
geninstall -u WSEAA60WBICoreComponent-6.0-0
- Remove 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.
- Remove the installation root directory. Type rm -rf install_root to remove WebSphere
Process Server directories. Ensure you specify the correct install_root for
the product you uninstalled. For example, if you uninstalled WebSphere
Process Server from the default directory /usr/IBM/WebSphere/ProcServer,
issue the following command:
rm -rf /usr/IBM/WebSphere/ProcServer
- 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
root 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
|/usr/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
/usr/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.
These files are located in 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.
- Run the odmclean.sh and aixclean.sh scripts.
Do not run the aixclean.sh script if the WebSphere
MQ product is installed.
- Obtain the scripts from the technote document
titled, Manual uninstall On AIX requires odmclean.sh and aixclean.sh on
the WebSphere Application Server Support site.
- Edit the odmclean.sh script and replace every
instance of the string /usr/WebSphere/AppServer with the
actual installation root directory.
- Run the aixclean.sh script from the command
line:
./aixclean.sh
- Run the odmclean.sh script from the command
line:
./odmclean.sh
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.
