Just a quick question. I know that Java work is zAAP eligible. And I know
that a lot of DB2 work is zIIP eligible. From what I've read, to be zIIP
eligible, the code must run in an "enclave SRB". What other products do
that? Unfortunately, our shop is very primitive. No DB2 or other RDMS. 99%
of our data is in either VSAM or sequential files. I'm thinking that a zIIP
would be useless in our environment. True?

To find out whether you'd offload anything in your current environment,
you can set PROJECTCPU in IEAOPTxx and look a the SMF72 Subtype 3
records or use the RMF postprocessor's Workload Activity Report to see
how much would be offloaded. There are some caveats (for instance,
later releases offload more stuff and might change the outcome), and
lots of info is available from:
