This document provides information on Adabas for zIIP, a selectable unit of Adabas that enables Adabas to make use of IBM’s zIIP engine. Whether running the basic Adabas nucleus, Adabas Cluster Services, or Adabas Parallel Services, Adabas for zIIP enables Adabas on z/OS to offload part of the Adabas 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 for zIIP may result in performance benefits by increasing the throughput for certain workloads.
Adabas for zIIP supports other selectable units that are integrated into the Adabas nucleus:
Adabas Caching Facility
Adabas Cluster Services
Adabas Delta Save Facility
Adabas Fastpath
Adabas Online System
Adabas Parallel Services
Adabas Review
Adabas SAF Security
Adabas Transaction Manager
Adabas Vista
Event Replicator for Adabas
Furthermore, Adabas for zIIP supports the following Adabas utilities:
ADACHK
ADACMP
ADAINV
ADALOD
ADAORD
ADAREP
ADARES
ADASAV
ADAULD
For more information on how Adabas Review and Event Replicator for Adabas support offloading workload to zIIPs, see their respective documentation sets.
