Calude, Thanks, I did a test and I do see some numbers showing up. However, there is still a concern of accuracy on a z890. I have been told that some vendor code will see it is running on a z890 and because it is a z890 not invoke (pre-emptable SRB) the code path that would put it on a zIIP. Therefore skewing the numbers. But, I am not sure which vendors or what products that would affect.
So we will run this way to collect number. We do have a z9 and a z890. The applications test on the z890 but want to know how much of their workload will translate to zIIP workload when it moves to production on the z9. Not knowing how to isolate which code (or vendor product) actually went to the zIIP using PROJECTCPU, I am not sure how reliable it will be. Unless someone has a way to say "this much zIIP work was done by product A and this much be product B", I am not comfortable the true results will be seen. I can say that during this timeframe of the workload running X% might go to a zIIP, but not much more beyond that.
