z Systems Application Assist Processor (zAAP)

Prerequisites for Java zAAP exploitation

The IBM z Systems Application Assist Processors (zAAPs) may be purchased and installed on the zEnterprise EC12 and zEnterprise BC12, zEnterprise 196 or zEnterprise 114 servers, System z10, and System z9 servers. (At minimum, z/OS 1.7 the IBM Solution Developers Kit (SDK) for z/OS, Java 2 Technology Edition, V1.4 with PTF (or later) for APAR PQ86689 and for WebSphere-based Java workloads, WebSphere Version 5.1 or later is required.)

The following table outlines the subsystems and minimum Java levels dependencies for determining zAAP Java execution and exploitation potential.

Consider zAAP on zIIP

Beginning with z/OS V1.11, z Systems Application Assist Processor (zAAP) eligible workloads are enabled to run on z Systems Integrated Information Processors (zIIPs). This function can enable you to run zIIP- and zAAP-eligible workloads on the zIIP.

See this page about requirements for zAAP on zIIP capability

This capability does not remove the requirement to purchase and maintain one or more general purpose processors for every two zIIP processors on the server
