Maintenance for the WebSphere® Application Server optional materials is similar to that for the base WebSphere Application Server for z/OS® product. Maintenance is applied using the System Modification Program / Extended (SMP/E), and then it is moved into production. The optional materials include feature packs and other interim deliverables.
Some feature-pack maintenance levels for WebSphere Application Server Version 7.0 are closely linked to specific base WebSphere Application Server maintenance levels. On distributed operating systems, feature-pack maintenance is applied automatically when base maintenance is installed. On z/OS systems, customers are responsible for upgrading feature-pack levels when this requirement is indicated in the installation materials for base service levels. Similarly, some feature pack service levels require a minimum base service level. These requirements generally are indicated in ACTION HOLD statements in the service level PTFs. If the WebSphere Application Server base service level is not appropriate for use with a specific feature-pack service level, feature-pack enabled servers do not start.
The WebSphere Application Server for z/OS service support Web site provides program temporary fix (PTF) lists for the base WebSphere Application Server for z/OS product and for each feature pack or other interim deliverable.
Contact the IBM® Software Support Center or consult the WebSphere Application Server for z/OS service support Web site to determine the PTFs for the required feature pack or interim deliverable maintenance levels, and order or download these PTFs.
The WebSphere Application Server for z/OS nodes that are upgraded to the new service level are now running with compatible WebSphere Application Server for z/OS and optional-materials maintenance.
Restarting a WebSphere Application Server for z/OS node at a previous service level normally involves simply switching the run time to use the previous level of code (datasets and product file system); the post-installer checks that any configuration changes made since the old level are backwards compatible.
