Ah. And I hadn't thought about it much, but it would be likely that enabling the zAAP would require a change to z/Linux dispatching as it did to z/OS as well as a modified JVM. Modifying the JVM might be OK. But to modify the z/Linux dispatcher would likely put out "too much" information about how the zAAP is enabled. Right now, that information is rather restricted so that some "hot shot" would not be as likely to try to "fake out" the z/OS dispatcher to get his own non-Java code to run on a zAAP. Of course, this later is just speculation on my part. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
