Re: z/OS 1.6 and more than 16 processors
Supposedly not. However, I can imagine some vendor of Java-based middleware doing so in the future. And likely charging the zAAP site for the total number of CPUs and zAAPs. Hum, I wonder if Oracle will do this. Some of their stuff is Java based, isn't it? Oracle uses their own JVM in the database server, so the zAAP will not be used. Oracle charges by the total number of engines that can execute Oracle. This is the number of Logical CPs in the Logical Partition. Their JVM is only used for stored procedures written in Java. The Oracle Installer (OUI) is a Java based GUI that installs Oracle products. This uses the host JVM, and so would use a zAAP if there was one available, but this has no effect on normal operation.
