Optimizing System z Batch Applications by Exploiting Parallelism

A draft IBM Redpaper publication

Abstract

This IBM® Redpaper™ publication shows you how to speed up batch jobs by splitting them into near-identical instances (sometimes referred to as “clones”). It is a practical guide, based on the authors’ testing experiences with a batch job similar to those found in customer applications. This guide documents the issues the team encountered and how we resolved them. The final tuned implementation produced considerably better results than the initial traditional implementation.
Because job splitting often requires application code changes, this guide includes a discussion of some aspects of application modernization you might consider if you need to modify your application.
The authors mirror the intended audience for this paper, since they are specialists in DB2®, IBM Tivoli® Workload Scheduler for z/OS® (TWS/z), and z/OS batch performance.
