You can 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.
Important: Throughout this topic, certain directory
paths are shown only in Linux and UNIX format for simplicity. The equivalent
Windows paths are identical except for the direction of the slashes.
The
following descriptions contain reference information about uninstalling interim
fixes, fix packs, and refresh packs on WebSphere Process Server:
- Overview of the uninstallation procedure
- To uninstall a maintenance package:
- Use the update installer to install the maintenance package, which creates
a backup file in the install_root/properties/version/update/backup directory.
IBM does not support user modifications to backup files.
- Use the update installer program to remove the maintenance package as
described in this topic.
- Viewing the fix level of the node
- You can use the versionInfo command in the install_root/bin directory
to display the exact fix and version level of the product. However, do not
use the versionInfo command while installing or uninstalling
a maintenance package.
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
The graphical interface requires the following information
that you must supply:
Table 1. Information required when uninstalling a maintenance packageField |
Valid values |
Description |
File path of the installation root directory of the WebSphere
product and the Update Installer |
Identify the installation root directory for IBM WebSphere
Process Server. |
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
- Log on as root on a Linux or UNIX operating system,
or as a member of the Administrator group on a Windows system.
On AIX platforms: In addition, verify
that the umask setting is 0022. To verify the umask setting, issue the following
command:
umask
To set the umask setting to 0022, issue the following command:
umask 0022
On HP-UX,
Linux and Solaris platforms: In addition, verify that the umask setting
is 022. To verify the umask setting, issue the following command:
umask
To set the umask setting to 022, issue the following command:
umask 022
- Change directories to the updateinstaller directory
in the installation root directory.
On Windows platforms: Use the Windows
Services panel to stop all services for WebSphere Process Server and WebSphere
Application Server processes.
- Stop all Java processes that use the IBM Software Developer Kit
(SDK).
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.
WebSphere Process Server processes include:
- Process server processes
- The nodeagent process on a node when the node is federated into a deployment
manager cell
- The dmgr process for the deployment manager server
Stop all Java processes, if necessary. If you uninstall a maintenance
package while a WebSphere Process Server-related Java process runs, IBM does
not guarantee that the product can continue to run successfully, or without
error.
- Determine if you are removing a maintenance package that updated
the IBM SDK, Java Technology Edition. If so, you can clone the IBM SDK from
the parent product to the Update Installer Wizard directory. Cloning the SDK
copies the install_root/java/jre directory
to the install_root/updateinstaller/java/jre directory.
The Update Installer for WebSphere Software searches known locations
for a suitable IBM SDK to use. In order, the Update Installer Wizard looks
for a valid Java Virtual Machine (JVM) in the following locations:
- The install_root/updateinstaller/java/jre directory
(when updating the product SDK)
- The install_root/java/jre directory
(preferred SDK to use)
On Linux and UNIX platforms: The directory
identified by one of the following environment variables on a Linux or UNIX
system: - JAVA_HOME
- JAVAHOME
- JRE_HOME
- JREHOME
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.
Important: To uninstall a fix pack or interim fix for the IBM SDK in
the parent product, do not start the Update Installer Wizard using the product
SDK that you intend to update. Using the SDK locks the SDK and prevents the
update. Copy the SDK from the
install_root/java/jre directory to the
install_root/updateinstaller/java/jre directory. The Update Installer Wizard uses the SDK in the
install_root/updateinstaller/java/jre directory
if it is present.
Alternatively, copy the IBM SDK from the parent product
to a temporary location and use the
-is:javahome ISMP
parameter to identify the location as you run the update installer command:
update -is:javahome="my_fully_qualified_temp_SDK_location"
- Use the update installer to uninstall the maintenance package.
Uninstall the interim fix on each application server node in a cell
before uninstalling the maintenance package from the process server node.
Issue
this command to uninstall the maintenance package with the most recent date
stamp and time stamp using the graphical user interface:
update -W update.type="uninstall"
To view tables that show all of the options available
when using the update command to uninstall maintenance
packages, see update command.
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.
