Uninstall WebSphere Application Server to remove the core product files.
Before you begin
If you have problems uninstalling
after upgrading a trial to the full product or
upgrading an Express® product
to the full base product, you might have used the product disc
image to upgrade a trial that was installed from a customized installation
package (CIP). You must use a full product CIP to upgrade a trial
CIP. Otherwise, you cannot uninstall the trial CIP. Use the manual
uninstall procedure in such as case. See Uninstalling manually for more information.
The uninstall command calls the uninstaller
program that is created during installation. The uninstaller program
is customized for each product installation, with specific disk locations
and routines for removing installed features.
The uninstaller program removes registry entries, uninstalls
the product, and removes all related features. The uninstaller program
does not remove log files in the installation root directory.
About this task
This procedure uninstalls the WebSphere
Application Server product.
See the
following topics to uninstall other components on the product disc:
The time required
to uninstall is dependent on the processing speed of your machine.
As a rough guideline, uninstalling the core product files and one
application server profile takes approximately 10 minutes when using
the uninstall command.
Procedure
Log on using the same
user ID that was used when the product was installed. Issue
the ls -al command at the root of the WebSphere Application
Server installation to find the user ID that was used to install the
product.
Log on as a user who belongs to the
Administrators group or as the user 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.
- Stop each running application server
with the stopServer command.
Stop
all server processes in all profiles on the machine. For example,
issue the following command from the
profile_root/bin directory
to stop the server1 process in the application server profile:
./stopServer.sh server1
If
a server is running and security is enabled, use the following command:
./stopServer.sh server1 -user user_ID -password password
- Optional: Back up configuration
files and log files to refer to them later if necessary.
Use
the AdminTask command scripting interface to create
a configuration archive file of an existing WebSphere Application Server profile, for
example.
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.
Back up the config folder
and the logs folder of each profile to refer
to it later if necessary. You cannot reuse profiles so there is no
need to back up an entire profile.
- Issue the uninstall command.
Supported configurations: On the Microsoft Windows 7 and Windows Server 2008 R2
operating systems, you might encounter the following error message
when you launch a graphical user interface to install or uninstall
the product:
The installer is unable to run in graphical mode. Try running the installer with the -console or -silent flag". This issue is specific to using Windows 7 or Windows Server 2008 R2.
For
more information, see the documentation about the problems using the
graphical installation process.
sptcfg
Run the
uninstall command:
The uninstaller wizard begins and displays
the Welcome panel.
You can also issue the uninstall command
with a silent parameter to use the wizard without the graphical user
interface.
Issue
the following command to start the uninstaller wizard in silent mode,
without the graphical user interface, and to remove all profiles.
Avoid trouble: If any of the profiles
were migrated to a new version of the product, you must either shut
down the new migrated deployment managers before uninstalling the
product, or include the removeProfilesOnUninstall="false" parameter
on the uninstall command. Either of these options prevents the migrated
profiles from being deleted when you uninstall the old version of
the product.
gotcha
- If you are using the wizard, click Next to
begin uninstalling the product.
The uninstaller wizard
displays a confirmation panel that lists a summary of the components
that you are uninstalling.
- Click Next to continue uninstalling
the product.
When
using the wizard, a panel allows you to choose whether or not the
uninstaller deletes all profiles before it deletes the core product
files. By default, all profiles will be deleted, but this option can
be deselected on the panel.
To change the default behavior,
start the wizard with this command:
uninstall -OPT removeProfilesOnUninstall="false"
After
uninstalling profiles, the uninstaller program deletes the core product
files in component order.
- Click Finish to close the wizard
after the wizard removes the product.
- Review the log file.
Review
the app_server_root/logs/uninstlog.txt file.
Review the app_server_root/logs/uninstall/log.txt file.
The log file records file system or other unusual errors.
Look for the INSTCONFSUCCESS indicator of success in the log:
(date_time),
Uninstall, com.ibm.ws.install.ni.ismp.actions.
SetExitCodeAction, msg1,
CWUPI0000I: EXITCODE=0
(date_time),
Uninstall, com.ibm.ws.install.ni.ismp.actions.
ISMPLogSuccessMessageAction, msg1,
INSTCONFSUCCESS
- If any product files remain, uninstall manually before
reinstalling.
The uninstaller program leaves some
log files, including the app_server_root/logs/uninstall/log.txt file.
Manually uninstall the product to remove all artifacts
of the product so that you can reinstall into the same installation
root directory. If you do not plan to reinstall, you do not need to
manually uninstall.
See Uninstalling manually for more information.
Results

Server product.
What to do next
