There is a special, undocumented & restricted, API to switch work from a CP to a zIIP. As far as I know, only the IBM Java JVM does this. Python is written in C (or maybe C++) and so I doubt it would qualify. Just as an aside, I can imagine (hope not) that at some point in time, use of a zIIP by "application code", even written in Java, will stop. I think that creating the zAAP back in the day was to lure "Web" work off of Windows/Linux to z/OS by making such work "free" if written in Java (or at least in Java byte code, running on the JVM). I know that I made a vain attempt many years ago to convince management to get a zAAP and start writing in Java. I even pointed out that CICS can run Java; as can batch. And that the programmers could use Windows Java tools to write and even do minor testing on their Windows desktop; saving MSUs by reducing TSO editing and running compiles on z/OS (since a Windows generated jar file, if properly written, can be uploaded and run on z/OS -- I've done it.) > Gadi Ben-Avi > z/OS systems Programmer > Malam Systems > Jerusalem, Israel > > -- This is clearly another case of too many mad scientists, and not enough hunchbacks.
