This procedure uninstalls the WebSphere Application Server product
from a Solaris system. After running the uninstaller program, manual steps
remove log files and registry entries that can prevent you from reinstalling
the product into the original directory. If you are not planning to reinstall,
do not 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.The uninstaller program leaves all profiles,
including all of the configuration data, applications, and other user data
in each profile. Use the -OPT removeProfilesOnUninstall="true" parameter on
the uninstall command to delete all of the data, or delete
it manually at a later time, if you decide the data is unnecessary.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.
Default directories are shown in the following
planning table:
The installation wizard and the Profile Management tool provide
an override for your own locations for root directories.
Use the installRegistryUtils command
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.
- 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. See Uninstalling the Web server plug-ins for WebSphere Application Server.
- 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
- Issue the uninstall command.
If you have already run the uninstaller program or
if you cannot run the uninstaller program, skip this step.
See the description of the uninstall command for more information.
The Uninstaller
wizard begins and displays the Welcome panel.
- Search for related packages. Type the following command
to search for packages for WebSphere Application Server products:
pkginfo | grep WS
If no packages appear when using these commands, skip the next
step. The resulting list of packages has the following format:
application WSBAA61 WebSphere Application Server
- Change directories to the directory where package information is
registered.
cd /var/sadm/pkg
- Issue the following command to remove any WebSphere Application
Server-related packages.
pkgrm packagename1 packagename2 packagename3 ...
Do not remove packages for WebSphere
Application Server products that you are not uninstalling. Version 6.1 package
names have a prefix of WSB or WSP and a suffix of 61. WSC package names do
not have a suffix of 61.
Issue
the following commands from the
/var/sadm/pkg directory
to search for and remove any WebSphere Application Server product-related
packages that are registered in the
/var/sadm/pkg directory:
- Change directories to the correct directory: cd /var/sadm/pkg
- ls |grep WSB|xargs -i pkgrm -n {} for WebSphere Application
Server products
- ls |grep WSC|xargs -i pkgrm -n {} for Application
Client
- ls |grep WSP|xargs -i pkgrm -n {} for Web server
plug-ins for WebSphere Application Server
Package names for Web server plug-ins for WebSphere Application
Server are:
WSPAA61
WSPAA61AC
WSPAA61BC
WSPAA61CC
WSPAA61DC
WSPAA61FC
WSPAA61FB
WSPAA61GC
WSPAA61HC
If there is a problem removing the packages, remove
the related package directories in the /var/sadm/pkg directory,
including the preremove files.
For example, remove
the following file before issuing the
pkgrm -n WSBAA61 command:
/var/sadm/pkg/WSBAA61/install/preremove
- Type rm -rf app_server_root to
remove WebSphere Application Server directories in the app_server_root directory.
Do not remove installation root directories for products that you intend to
keep. Remove all of the profile directories as well.
- Use the installRegistryUtils command
to examine the installation locations for all installed WebSphere Application
Server products and remove the desired products from the install registry.
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.
