With whomever is selling you the z9 BC, try it. See if you can reach an
agreement to test two or three different configurations (maybe 1, 2, and 3
CP configurations centered around the capacity level you're aiming for).
For example, see if you can get a Capacity On Demand contract in

We have discussed the validity of the UP recommendation around our shop

That is really not true anymore with modern CICS.
Also, each thread to DB2 is capable of parallelism.
And, the other workloads should benefit, as well.

Personally I'd be believing the vendor.
If they reckon their code is incapable of using new (???) functionality,
who's to argue.
More engines can always be used to some extent, but if the business
needs only one big(-er) engine, that's the way to go.

That may be true, but John has one CP and is looking at 2 CPs, so straight
