PowerExchange zIIP Exploitation

The IBM System z Integrated Information Processor (zIIP) is designed to help free up general computing capacity and lower the overall total cost of computing for certain data and transaction processing workloads on z/OS. The zIIP can execute any suitable workload provided that software is designed to run the workload on the zIIP.

If you have one or more zIIPs installed, you can configure the PowerExchange Listener on z/OS so that some of its work is offloaded to a zIIP. If multiple PowerExchange Listeners are running, you can configure each of them to offload work to a zIIP.

To be eligible to run on a zIIP, work must meet the following requirements:

Run in a WorkLoad Manager enclave that is classified as being able to offload to a zIIP, also called a System Utility Processor (SUP)

Run in an enclave System Request Block (SRB)

Programs that run in an SRB must meet the following requirements:

Run in Supervisor state, key zero.

Do not issue SVCs except for SVC 13 (ABEND).

For subroutines, do not call another subroutine.
