zAAP's are indeed used by Java code running on a TCB. However, to my knowledge, it does not follow that: With zAAP on zIIP, they must be using SRB's. IBM determines the rules in this regard. To me (as both an ISV and System z developer), IBM allowing more code to run on specialty engines is

. If fact, there's an option to not even run it under an Enclave SRB. This approach holds true for the following products: HB Base, HB JavaScript Engine, HB Socket Support. HB BPIC (Batch Programs Inside CICS) doesn't exploit zIIP. Russ Teubner HostBridge Technology www.hostbridge.com

of our zIIP-enablement RD we compared the cost of: (a) frequently starting Enclave SRBs, and (b) using a persistent Enclave SRB in conjunction with MVS Suspend/Resume services. We actually ended up using both techniques in our product (although in different situations). Russ Teubner HostBridge
