A good place to start when trying to determine what combination of components will work with a specific version of WebSphere Process Server is the Detailed System Requirements page on the Process Server support site.
As stated on the individual pages for the product version, we list out the base product and fix pack levels that should work for a particular version of WebSphere Process Server. It has come to our attention that there are some dependencies from the Feature Packs for SCA and XML, primarily with regard to the BO Lazy parsing feature of WebSphere Process Server V220.127.116.11, that require a certain version of the feature packs to be installed.
Specifically, with WebSphere Process Server V18.104.22.168, it is required to have the feature pack levels be at:
- Feature Pack for SCA Version 1.0.1 Fix Pack 7
- Feature Pack for XML Version 1.0.0 Fix Pack 7
The Detailed System Requirements page states that these are needed as a minimum, but since there are changes in the later feature pack updates, this is actually what is required instead of just being the minimum. A formal technote is also being put together to document this.
The tricky part is that if you are using Installation Manager to update your WebSphere Process Server product, it will recommend the latest and greatest version of the feature packs, which, at this time, is the Feature Pack for SCA Version 1.0.1 Fix Pack 11 and the Feature Pack for XML Version 1.0.0 Fix Pack 9. By following these recommendations, your product will be in an unsupported configuration and can cause issues.
In this situation, the configuration is not supported only if you are using the Lazy Parsing mode.
The Installation Manager itself cannot know of these requirements, so we are unable to put a sanity check in that tool when the upgrade is being done using the online repository.
