Similar to maintenance done to the base WebSphere Application Server for z/OS product, maintenance to the WebSphere Application Server Optional Materials is applied using SMPE, then moved into production. Optional Materials includes feature packs and other interim deliverables, all shipped as maintenance to FMID JIWO610.
In general, feature pack maintenance levels for WebSphere Application Server Version 6.1 are closely linked to base WebSphere Application Server maintenance levels. On distributed platforms, feature pack maintenance is applied automatically when base maintenance is installed. On z/OS, customers are responsible for upgrading feature pack levels whenever base service levels are upgraded. If the WebSphere Application Server base service level is higher than the feature pack service level, feature-pack enabled servers will not start.
The WebSphere Application Server for z/OS service support page provides PTF lists for base WebSphere Application Server for z/OS, and for each feature pack or other interim deliverable. The general rule is that each feature pack level will run correctly with base WebSphere Application Server at the same level, or one level higher. Thus, Feature Pack Services Version 6.1.0.13 will run with base WebSphere Application Server Version 6.1.0.13 or Version 6.1.0.14. If you upgrade the base WebSphere Application Server code to Version 6.1.0.15, you will also need to install a new level of Feature Pack for Web Services Version 6.1.0.15.
What to do next: Decide which base WebSphere Application Server for z/OS maintenance level you will be upgrading to, and which feature packs or other interim deliverables will need to be upgraded.
Contact the IBM Software Support Center or consult the WebSphere Application Server for z/OS support page 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 runtime to use the previous level of code (datasets and product filesystem); the post-installer will check that any configuration changes made since the old level are backwards compatible.
