Are the any z/OS 1.9 uniprocessor configs out there? Have any default settings changed in 1.9 that I should look at? I am reviewing a uniprocessor white paper from Dec 2006. Any other ideas??
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.)
We got away from uniprocessors once goal mode became a requirement. Without compatibility mode, we lost control over system priorities.We don't have enough transaction completions in each service class to make WLM responsive enough to keep people from observing extremely frustrating slow downs. Our first 2-way was like a breath of fresh air...
