First, there is an entirely legitimate way to make your application code zIIP-eligible: write it in Java. If that's not going to fly, perhaps you can find a COBOL to Java translator. Second, not all zIIP-eligible work runs in SRB mode. Certainly all that zIIP-legit JVM code does not. IBM knows how to dispatch TCBs on a zIIP, but they don't tell even ISVs how to do it. I believe that is what Neon Systems figured out on their own, and offered to their customers, presumably to their eventual regret. (To be clear, *I* have no idea how to do it, and I am not recommending that you try.) Third, I understand that the new zCX container stuff is or can be made zIIP-eligible. If you think can run your COBOL programs in that environment, it might be to your advantage.

Absolutely, and I think some of the responders covered that point. The restriction against SVCs is a killer all by itself.

Others have beaten this general topic pretty well to death but let me address just that one question. The answer is No. You can only mark something "zIIP-eligible."

Re: Using COBOL on ZIIP via SRB etc
As others have mentioned, running application code on a ZIIP is a violation of your license. Aside from that, SRBs run in Supervisor state, introducing potential integrity exposures.
