Uninstall the
feature pack to remove the core product files.
Before you begin
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.
If
you have a feature pack installed, uninstalling the WebSphere Application
Server product using the Version 6.1.0 uninstaller program causes the feature
pack to stop working because the uninstallation removes the server. However,
you can uninstall the feature pack after uninstalling the WebSphere Application
Server product. This same limitation applies if you are uninstalling a CIP.
About this task
This procedure uninstalls the feature
pack.
Uninstalling
a feature pack changes feature pack profiles. Uninstallation makes an application
server profile that previously was augmented for the feature pack unusable
and no longer valid. Uninstallation unaugments a deployment manager profile,
resulting in deployment manager profile that is usable and still valid.
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.
- If the feature
pack is installed on a Network Deployment product, stop the node agent process
with the stopNode command.
Stop the node
agent process that might be running on the machine. For example, issue the
following command from the
profile_root/bin directory
of a federated node on a Linux machine to stop the node agent process:
./stopNode.sh
If servers are running and security is enabled, use the
following command:
./stopNode.sh -username username -password password
- If the feature
pack is installed on a Network Deployment product, stop the deployment manager
dmgr process with the stopManager command.
Stop all dmgr processes
that are running on the machine. For example, issue this command on a Linux
machine from the
profile_root/bin directory
of the deployment manager profile:
./stopManager.sh -username username -password password
- 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
If
you have multiple servers, you can use the
serverStatus command
to find running application servers. Issue the following command from the
profile_root/bin directory
to determine which servers, if any, are running:
./serverStatus.sh -all
- Optional:
Back up configuration files, profiles, and log files to refer to them
later if necessary.
Use the backupConfig command
to back up configuration files and profiles.
- Issue 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 interfaces:
uninstall -silent -OPT unaugmentDmgrProfiles="true"
- 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.
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.
- If the uninstallation
program did not uninstall the feature pack enablement extensions, use the
Update Installer to uninstall the enablement extensions.
See Uninstalling a fix pack, interim fix, interim feature or test fix using the graphic user interface.
- Review any
log files if necessary.
- If any product files remain, uninstall manually before reinstalling.
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.
If
necessary, delete the uninstall_websv directory for the
Web Services feature pack if necessary.
Results
This procedure results in uninstalling the product.
Any
application server profile that previously was enabled with the feature pack
is no longer valid. Any deployment manager profile that previously was augmented
for the feature pack is unaugmented resulting in a deployment manager profile
that is still valid.
What to do next
After uninstalling the product and cleaning the system with the
manual uninstall procedure, you can reinstall.

an overview of installing the product and creating a functional e-business
environment.
