This document provides information on Adabas System Coordinator for zIIP, an option of the Adabas System Coordinator that enables the Adabas System Coordinator Daemon to make use of IBM’s zIIP engine.

Adabas System Coordinator for zIIP enables the Daemon on z/OS to offload part of the Daemon workload from the mainframe’s general processors (GP) to System z Integrated Information Processors (zIIP).

Offloading work from the GPs will free up some of their capacity. This helps decrease the total cost of operation (TCO) of the GPs and makes room for running additional workload on them. Furthermore, the use of Adabas System Coordinator for zIIP may result in performance benefits by increasing the throughput for certain workloads.

Adabas System Coordinator for zIIP supports other selectable units that are integrated into the Daemon:

• Adabas Fastpath

• Adabas Transaction Manager

• Adabas Vista

• Adabas SAF Security
