Are you serious that SSA has sized you for a "server" AS/400 when you are
running mixed-mode V6.X???

Mixed-mode BPCS places its workload in the interactive subsystem.  The server
series AS/400s are designed NOT to run optimally (the 400 actually, purposely
de-tunes itself -- thus your CFINT jobs) with high interactive workloads.

With 250 users, I can't see how anyone would have recommended an S-anything.
Although I am not advising you on the proper size machine for your purpose, you
will most likely need an interactive box such as a Model 620, 640.  And yes,
this will cost you dearly.

Please feel free to call me if you want more details on this

Best of Luck,
