This topic describes how to use the Update Installer for WebSphere Software to uninstall interim fixes, fix packs, and refresh packs. The Update Installer for WebSphere Software is also known as the update installer program, the updateInstaller program, and the Update installation wizard.
Before you begin
Use the proper authorizations to successfully uninstall product updates. Use the update installer program as the root user on a Linux or UNIX platform, or as the administrator on a Windows platform.
The Update Installer wizard is an InstallShield for Multiplatforms wizard that runs with either a graphical user interface or in silent mode with a response file.
Do not launch multiple copies of the Update Installer wizard at one time: Concurrent launches of the update installer program are not supported. Performing more than one update at the same time can produce unpredictable results, which might include a failed or faulty installation.
Required information
Field | Valid values | Description |
---|---|---|
File path of the installation root directory of the WebSphere product and the Update Installer | Identify the installation root directory for one of
the following products:
|
The Update Installer application defaults to select the product in its parent directory. |
File name of the maintenance package to uninstall. | Select a maintenance package to uninstall from the install_root/properties/version/ update/backup directory. | The default maintenance package is the package with the latest date stamp and time stamp in the install_root /properties/version/ update/backup directory. |
Why and when to perform this task
The following procedure describes how to uninstall a maintenance package.
Steps for this task
Before uninstalling interim fixes, fix packs, and refresh packs on a machine, stop all Java processes on the machine that use the IBM SDK, Java Technology Edition that WebSphere Application Server provides.
WebSphere Application Server processes include application server processes, such as the process created when server1 is running.
Stop all Java processes, if necessary. If you uninstall a maintenance package while a WebSphere Application Server-related Java process runs, IBM does not guarantee that the product can continue to run successfully, or without error.
When no JVM is present in one of the first two locations, set one of the environment variables to point the Update Installer wizard to a valid JVM.
The preferred SDK for starting the Update Installer wizard is the SDK in the parent product. Always use the product SDK when possible.
update -is:javahome="my_fully_qualified_temp_SDK_location"
Command example | Type of installation | Description |
---|---|---|
update -W update.type="uninstall" | Graphical interface mode | Initializes the maintenance package field with the name
of the maintenance package that was most recently installed. Accept all of the default values to uninstall the maintenance package with the most recent date stamp and time stamp. |
update -W product.location="e: \IBM\WebSphere\AppServer" -W update.type="uninstall" | Graphical interface mode | Overrides the graphical interface with the location of the WebSphere software to update. The default maintenance package to uninstall is the most recently installed maintenance package for that software. |
update -W backup.package="PQ20029.pak" -W update.type="uninstall" | Graphical interface mode | Overrides the maintenance package field with the name of the maintenance package to uninstall. |
update -W product.location="e: \IBM\WebSphere\AppServer" -W backup.package="PQ20029.pak" -W update.type="uninstall" | Graphical interface mode | Overrides the location of the WebSphere software to update and the name of the maintenance package to uninstall. |
update -options "responsefiles/file_name" | Graphical interface mode with an options file | Overrides all default values with values that you specified
in the options response file. If you omit either value from the response file, the default maintenance package is the installed package with the most recent date stamp and time stamp. The default software is the software installed in the parent directory. |
Command example | Type of installation | Description |
---|---|---|
update -W update.type="uninstall" -silent | Silent mode | Uninstalls the maintenance package with the most recent date stamp and time stamp to update the software that is installed in the parent directory. |
update -W product.location="e: \IBM\WebSphere\AppServer" -W update.type="uninstall" -silent | Silent mode | Overrides the default location of the WebSphere software to update. The default maintenance package to uninstall is the most recently installed maintenance package for that software. |
update -W backup.package="PQ20029.pak" -W update.type="uninstall" -silent | Silent mode | Overrides the interim fix field with the name of the maintenance package to uninstall. |
update -W product.location="e: \IBM\WebSphere\AppServer" -W backup.package="PQ20029.pak" -W update.type="uninstall" | Silent mode | Overrides the location of the WebSphere software to update and the name of the maintenance package to uninstall. |
update -silent -options "responsefiles/file_name" | Silent mode with an options file | Overrides all default values with values that you specified
in the options response file. If you omit either value from the response file, the default maintenance package is the installed package with the most recent date stamp and time stamp. The default software is the software installed in the parent directory. |
Result
This procedure results in uninstalling maintenance packages to update WebSphere software.
What to do next
After uninstalling maintenance packages, you can continue to use the WebSphere software.
