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 correct authorizations to successfully install
product updates.
The Update Installer is an InstallShield MultiPlatform
wizard that runs with either a graphical user interface or in silent
mode with a response file: uninstall.txt.
Note: On i5/OS® platforms: The Update
Installer on i5/OS runs only
with the response file.
Important: Throughout this topic, certain directory paths are
shown only in Linux® and UNIX® format for simplicity. The
equivalent path for i5/OS is
identical to Linux and UNIX. 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 ESB:
- Overview of the uninstallation procedure
- To uninstall a maintenance package:
- Make sure that you have the backup file that was created when
you used the update installer to install the maintenance package:
it should be located in the install_root/properties/version/nif/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 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 |

Identify the installation root directory for IBM WebSphere ESB. |
The Update Installer application defaults to the
last-visited product location. |
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. |
Required security role for this task: Use the
correct 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.
To
remove an interim fix, a fix pack, or a refresh pack, perform the
following steps.
Procedure
- Log on to the operating system.

On Linux and UNIX platforms: In addition,
verify that the umask setting is 0022.
To verify the umask
setting, type the following command: umask.
To
set the umask setting to 0022, type the following command: umask
0022
- Change directories to the update installer directory. The update installer directory is located in one of the following
locations, depending on the operating system that you are using:
On AIX® platforms: /usr/IBM/WebSphere/UpdateInstaller
On i5/OS platforms: /QIBM/ProdData/WebSphere/UpdateInstaller/V61/UPDI


On HP-UX, Linux and Solaris platforms: /opt/IBM/WebSphere/UpdateInstaller
On Windows platforms: C:\Program
Files\IBM\WebSphere\UpdateInstaller
On Windows platforms: Use
the Windows Services panel
to stop all services for WebSphere ESB and WebSphere Application Server
processes.
- Stop all Java™ processes
that use the IBM Software Developer
Kit (SDK) or IBM Developer Kit
for Java (JDK and used on i5/OS platforms).
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 ESB processes
include:
- Server processes
- The node agent 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 ESB-related Java process runs, IBM does not guarantee that the product can continue
to run successfully, or without error.
- Use the update installer to uninstall the maintenance package.
- To uninstall the maintenance package using the graphical user
interface, type one of the following commands:
On Windows platforms: update.bat
-W update.type="uninstall" to uninstall the maintenance
package with the most recent date stamp and time stamp using the graphical
user interface.

On Vista and Windows 2008 platforms: update.exe
-W update.type="uninstall" to uninstall the maintenance
package with the most recent date stamp and time stamp using the graphical
user interface.

On Linux and UNIX platforms: ./update.sh
-W update.type="uninstall" to uninstall the maintenance
package with the most recent date stamp and time stamp using the graphical
user interface.
On Windows platforms: update.bat
-options "responsefiles/file_name" to
override all graphical interface values with values that you specified
in the options response file. For more information about the example
response file that is installed with the update installer, see the uninstall.txt topic in the WebSphere Application Server Network Deployment,
version 6.1 documentation.

On Vista and Windows 2008 platforms: update.exe
-options "responsefiles/file_name" to
override all graphical interface values with values that you specified
in the options response file. For more information about the example
response file that is installed with the update installer, see the uninstall.txt topic in the WebSphere Application Server Network Deployment,
version 6.1 documentation.
On i5/OS platforms: ./update -options
"responsefiles/file_name" to uninstall
without a graphical user interface, using the values that you specified
in the options response file. For more information, see the uninstall.txt topic in the WebSphere Application Server Network Deployment,
version 6.1 documentation.

On Linux and UNIX platforms: ./update.sh
-options "responsefiles/file_name" to
override all graphical interface values with values that you specified
in the options response file. For more information about the example
response file that is installed with the update installer, see the uninstall.txt topic in the WebSphere Application Server Network Deployment,
version 6.1 documentation.
- To uninstall the maintenance package as a background process,
using the silent mode, type one of the following commands:
On Windows platforms: update.bat
-silent -options "responsefiles/file_name"
to uninstall without a graphical user interface, using the values
that you specified in the options response file. For more information,
see the uninstall.txt topic in the WebSphere Application Server Network Deployment,
version 6.1 documentation.

On Vista and Windows 2008 platforms: update.exe
-silent -options "responsefiles/file_name"
to uninstall without a graphical user interface, using the values
that you specified in the options response file. For more information,
see the uninstall.txt topic in the WebSphere Application Server Network Deployment,
version 6.1 documentation.

On Linux and UNIX platforms: ./update.sh
-silent -options "responsefiles/file_name" to
uninstall without a graphical user interface, using the values that
you specified in the options response file. For more information,
see the uninstall.txt topic in the WebSphere Application Server Network Deployment,
version 6.1 documentation.
Note: Uninstall the interim fix on each server node in a cell
before uninstalling the maintenance package from the deployment manager
node.
To view tables that show all of the options available
when using the update command to uninstall maintenance
packages, see the update command topic in the WebSphere Application Server Network Deployment,
version 6.1 documentation.
- If you uninstall a fix pack, the Update
Installer does not uninstall fix pack updates from profiles. The reason
for not removing this maintenance is that you might have configured
the profile after installing the maintenance. To restore an original
profile, use the restoreConfig command to restore
your backup. See Backing up and restoring administrative configurations for
more information about running this command. For detailed
installing or uninstalling instructions, please refer to the instructions
provided with your fix pack or refresh pack.
Results
The interim fix, fix pack or refresh pack is removed, and
the previous version of WebSphere ESB software
remains on your system.
What to do next
After uninstalling maintenance packages, you can continue
to use the WebSphere software.
