Hi, We have 3 clients (all hospitals) that have converted to the same software mix. I have to admit that there were some initial problems because of some software issues that caused the test CICS region running the application at one of the sites that caused the region to spike badly when there were other processors that were "virtually" free, but the problem was located and the vendor fixed it. All three sites have been running for at least a year now with multiple processors and one is using a Z9 (the other two are on z/890's), and there doesn't appear to be any problems relating to the application needing a big UP to run normally.
That's not to say that the application isn't a hog, because it is, but performance wise, there is no indication that a big-UP would have any advantages at all over the multi-processors that the sites currently have. I don't know how your site rates (necessary capacity) compared to them, but they are quite large, and I can guarantee that there are no indications that they need a bigger processor for any of their individual CICS regions, including the ones that run that application. these sites were never UP sites to begin with, at least not in the several years that I have been supporting them, but none of my performance tuning or capacity reports shows anything amiss.
