by L. W. Wyman, J. Castaņo, J. P. Kubala, R. J. Maddison, B. R. Pierce, R. R. Rogers
With the addition of IBM System z™ application assist processors (zAAPs) and integrated information processors (zIIPs) to the portfolio of special-purpose IBM System z processors, the reinvention of the IBM mainframe continues. Jointly, zAAPs and zIIPs provide significant IBM System z9™ integrated and cost-effective processing cycles for today's strategic Java™ and DB2® for z/OS® programming platforms which are increasingly fundamental to enterprise-class business environments. Overviews of zAAPs and zIIPs are presented that describe their functionality, design, and use by the z/OS operating system to achieve the execution of both Java and z/OS DB2 programming functions.
