Bill,
A zAAP (zSeries Application Assist Processor) is a processor engine which
absorbs a percentage of JAVA workload, available for z990/z890. A large
benefit of a zAAP is that OS software charges don't apply to it's use.

And in case that doesn't sound familiar, you may have heard it
referred to as an IFA (Integrated Facility for Applications - similar
to Linux IFL). That was the name before the marketing people at IBM
got involved. You still see that name used in various places like
RMF reports and the HMC.
IMHO it is also worth to say about LPAR weights with zAAP aka IFA.
I was told (it's not my observation) about some gotcha's when different
types of processors (CP, IFC, IFL, IFA) are in use, especially when CF
LPARs are in use (due to 'active wait').
