Apply maintenance updates and program fixes to the product components.
Before you apply service to any component, check that you have backed up any associated resources, including the database used by any brokers on this computer. You might also choose to back up installation and work path directories. For details of this task, see Backing up resources.
You can download maintenance updates for WebSphere® Message Broker from a Web site, in the form of a Program Temporary Fix (PTF), also known as a fix pack. Fix packs are cumulative, therefore, if multiple fix packs are available, you do not have to install a previous fix pack before you install the latest available. However, you must first install the GA code to ensure that you comply with your license agreement. You can find the latest information about available fix packs on the WebSphere Message Broker support Web page.
In some circumstances, fix packs are also provided as a
media refresh; CDs and DVDs are recreated, and electronic images on IBM® Passport Advantage® are replaced.
Check with your IBM representative if you want a media refresh.
If you have installed the Trial Edition, you can apply service
to this installation, provided that you are within your 90 day trial
period.
Fix packs for WebSphere Message Broker are installed using the same technology as the GA release. Therefore product files are consistently tracked and updated appropriately.
If you have applied any interim fixes to your existing installation, contact your IBM Service representative for instructions and possible updated interim fixes for the fix pack level that you are installing.
Because you can install more than one copy of WebSphere Message
Broker runtime components on a single
computer, you can choose how to apply service:
When you apply the fix pack, the new level of the product overwrites the existing level. You must stop all components before you apply service. All the components and resources that you have defined are retained. When the fix pack is successfully installed, restart the components.
Fix packs are supplied as complete installations. You can install the product in a new location on your computer by using the fix pack packages. You can do this only within the terms of your license:
This option provides several advantages:
If you already have more than one installation on the computer, read the additional information in Applying service on computers with multiple installations.
Download the latest fix pack from the WebSphere Message Broker support Web page:
If you have installed WebSphere Message Broker runtime components more than once on a single computer, you can choose to apply service to one or more of these installations in any order. You might therefore choose to install a service level on one instance initially, and complete some tests, before you apply the fixes to additional installations. You can also choose to run a subset of components at the new level of service, and leave others at the original level.
You must ensure that you comply with the terms of your license
at all circumstances.
If you decide to return to a previous level, stop the component, run the mqsiprofile command that is associated with the installation at the previous service level, and restart the component.
For further details about working with multiple installations, see Command environment: Windows platforms and Command environment: Linux and UNIX systems.
For further information about components, see z/OS customization overview.
If you have a single installation on a computer, and you want to apply service, you must stop all runtime components, apply service, and restart the components. The service is applied to the product code and you can start the components immediately to run against the new service level.
