The z/OS XML System Services can exploit zAAP as well, and thus many
software products and applications which use the XML System Services can
exploit zAAP. DB2 9's XML processing is one example.

The zAAP or zIIP procurement question has a relatively simple answer (for a
static analysis). You just pull out the RMF report for at least your
monthly peak interval, find out how much (if any) zAAP- or zIIP-eligible
workload was running at that interval, translate that into an MSU count,

"It depends," but if we're talking about steady state execution, and
business functions that could be reasonably implemented in either language,
and "best practices" performance engineering in both languages (not a
given, unfortunately), then Java (which is just-in-time compiled) would
consume some

That's the entire question. Assume a programmer is good at both languages. Also
assume that the work to be done can be done in both languages without a bunch
of "funny" stuff. I wonder which would take less CPU, on average. If I had a
zAAP, I'd likely go with Java. If I needed to to ISPF macros,
