<snip> I would be surprised to see anyone running z/OS on a uniprocessor these days. In yesteryear, before millicode-based knee capping, uniprocessors were not uncommon because of the hardware costs. But, these days, IBM can knee-cap System z machines down to incredibly small MSU values. (I know. We're running one of them now.) </snip>
We have one - z9bc uni capped at 15 MSUs. The vast majority of our work runs under a single TCB IDMS address space. Moving this onto a 2 way would cause our users response time problems. Rumor has it that the latest release of IDMS will run on a zIIP (or whatever the database engine is). Once we get there and ready for a replacement processor, I will be definitely looking at putting in the specialty engine and cutting the z/OS processor back smaller - depending on how much of the workload will actually transfer of course.
