The TRIRIGA 3.5.1 compatibility matrix says that WebSphere 188.8.131.52 is supported, but also that “Future fix packs for this version are also supported.” If you run the TRIRIGA 3.5.1 installer with the full version of WebSphere 184.108.40.206 in place, the install works. If you try running with the full version of WebSphere 220.127.116.11 in place, however, the following error occurs:
“WebSphere Problem: WebSphere version is too old. The version of WebSphere that was detected is too old. IBM TRIRIGA Application Platform requires WebSphere version 18.104.22.168 or newer.”
This problem was seen when performing the TRIRIGA 3.5.1 install on Windows. It may exist when running the installer on other operating systems, as well.
