Uninstall a WebSphere® Application Server
product from an AIX® system by running the uninstaller program
and performing some manual steps to remove log files and registry
entries. Such registry entries can prevent you from reinstalling the
product into the original directory. If you are not planning to reinstall,
you do not have to uninstall manually.
Before you begin
The uninstaller program
removes all profiles by default, including all of the configuration
data and applications in each profile. Before you start the uninstall
procedure, back up the config folder, the installableApps folder,
and the installedApps folder of each profile,
if necessary, or use the -OPT removeProfilesOnUninstall="false" parameter
on the uninstall command.See Using command line tools for
a description of managing configuration files. Back up all applications
that are not stored in another location.
Determine the
installation root directory for the product so that you remove the
correct product and produce a clean system.
About 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 a WebSphere Application Server product. A
clean system lets you reinstall the product into the original directory
without coexistence.
Table 1. Default directories. Default
directories are shown in the following planning table:
Identifier |
Directory |
Actual location |
app_server_root |
/usr/IBM/WebSphere/AppServer |
|
profile_root |
/usr/IBM/WebSphere/AppServer/profiles |
|
plugins_root |
/usr/IBM/WebSphere/Plugins |
|
The installation wizard and the Profile Management Tool provide an override
for your own locations for root directories.
Use
the installRegistryUtils command
that is located on the product disk to examine the installation locations
for all installed WebSphere Application
Server products.
Perform the following procedure
to produce a clean system.
Procedure
- Log on as the same user ID who installed
the product.
- Use the kill command to
kill all Java™ processes that
are running.
If running Java processes
are not related to WebSphere Application
Server products and it is not possible to stop them, stop all WebSphere Application Server
product-related processes. Use the following command to determine
all processes that are running:
ps -ef | grep java
Stop
all WebSphere Application
Server-related processes with the
kill command.
kill -9 java_pid_1 java_pid_2...java_pid_n
- Run the uninstaller program for the Web server
plug-ins for WebSphere Application
Server.
If a Web server is configured to run with the
application server, uninstall the plug-ins to remove the configuration
from the Web server.
- Issue the uninstall command.
If you have already run the uninstaller program, skip
the rest of this procedure. If you cannot run the uninstaller program,
go to the next step.
app_server_root/uninstall/uninstall
See the description of the uninstall command for more information.
The
Uninstaller wizard begins and displays the Welcome panel.
- List WebSphere Application Server components
that are installed.
Type the following command to search
for related packages:
lslpp -l| grep -i WS
Do not remove packages for WebSphere Application Server
products that you are not uninstalling. Version 7.0 package names
have a prefix of WSB or WSP and a suffix of 70. WSC package names
do not have a suffix of 70.
- Change directories to the /usr/IBM directory,
or the equivalent top directory of your install.
- Type rm -rf WebSphere to delete this WebSphere Application Server-related directory,
but only if the AppServer directory is the only
directory within the WebSphere directory. Delete
the directory if the only products contained in the directory are
products that you intend to delete.
- Use the installRegistryUtils command
that is located on the product disk to examine the installation locations
for all installed WebSphere Application
Server products and remove the desired products from the install registry.
- Edit the vpd.properties file.
The file is located in the root directory
or in the /usr/lib/objrepos directory.
Do
not delete or rename the vpd.properties file
because the InstallShield MultiPlatform (ISMP) program uses it for
other products that it installs. If the WebSphere Application Server
product that you are uninstalling is the only product with entries
in the vpd.properties file, you can delete this
file.
At this point, it should be possible to reinstall WebSphere
Application Server. If not, run the odmclean.sh and aixclean.sh scripts
as described in the next step.
- Run the manual complete cleanup scripts on the WebSphere
Application Server Support site. Obtain the scripts from the technote
document titled, Manual complete cleanup scripts for WebSphere Application
Server V5.0, V5.1, V6.0, and V6.1 on AIX and IBM HTTP Server V1.3,
V2.0, V6.0, and V6.1 on AIX .
Carefully review
the technote and download one or both of the attached scripts. Note
that one of the scripts is intended for cleaning WebSphere Application
Server product entries, and the other script is intended for cleaning
IBM HTTP Server product entries. The technote contains helpful reference
information regarding the WebSphere Application Server installer's
use of the AIX ODM.
Results
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.
