Also curious about the "It also gives our end users the idea that z/OS is
incapable of easy to use data access" remark, John.

If you're a keen or semi-keen observer of the IT world, relational
databases are extremely popular and continuing to be popular, but
non-relational databases (and data stores) are enjoying a robust
renaissance. One size does not fit all.

I think it's always a good idea to take a look at the full range of
VSAM-related options: SYSB-II, VSAM Record-Level Sharing (RLS), and
Transactional VSAM (TVS). And, to anticipate a question, no, you do NOT
need multiple machines for either VSAM RLS or TVS. You don't even need more
than one z/OS LPAR -- a monoplex is sufficient. You do need to define and
to start a CFCC LPAR (or z/VM equivalent if applicable) if you don't have
one already -- otherwise known as a configuration task, and all approaches
require configuration tasks. That CFCC LPAR can either use (part of) a
general purpose engine or a CF engine, and it needs a bit of memory
allocated. The fact CFCC-related processing can run on a CF engine is a
good, very zIIP-like option to have available because all these approaches
incur some overhead. Whether it makes business sense to get a CF engine or
not depends on how much CFCC-related processing you'll have. Often yes it
does, but not always. The processing may grow with time as you use RLS or
TVS more (and/or use your CF for other things) -- yes, new functions often
get used and enjoyed -- so that decision can change over time, too.
