Oh my. Where I am now we just upgraded the mainframe to a Z14, this machine and software running is not even the current OS for the platform. For my twenty plus years there have been projects afoot to replace it but nothing ever pans out. This machine works in concert with a very large iSeries that for the last ten years has been rumored to be on the table to replace. Then throw in all the AIX/Oracle machines and you get the picture. The one common reason why all replacement attempts falter if not fail. No one knows all the touch points. No one knows exactly what they really do. Oh its easy to say "that machine is the warehouse inventory and related" but on a grand scale that is a fine description. it is when you get into all the custom interfaces, all the different systems relying on it, then it becomes a whole different ball game. I full expect the z, i, and p, machines to all be there in the next ten to fifteen years for the same reason they are here now. it gets really expensive to replace something when you don't even know what you truly have. when you do find out it can be far more economical to keep what you got but be more diligent where new apps reside.
