Using IBM z/OS WLM to Measure Mobile and Other Workloads

A draft IBM Redpaper publication

Abstract

This IBM® Redpaper™ publication discusses the need to monitor and measure different workloads, especially mobile workloads. It introduces the workload classification capabilities of IBM z Systems™ platforms and helps you to understand how recent enhancements to IBM MVS™ Workload Management (WLM) and other IBM software products can be used to measure the processor cost of mobile workloads.

This paper looks at how mobile-initiated transactions in IBM CICS®, IMS™, DB2®, and WebSphere® Application Server can be “tagged and tracked” using WLM. For each of these subsystems, the options for classifying mobile requests and using WLM to measure mobile workloads are reviewed.

A scenario is considered in which a bank is witnessing a significant growth in mobile initiated transactions, and wants to monitor and measure the mobile channels more closely. This paper outlines how the bank can use WLM to do this.

This publication can help you to configure WLM mobile classification rules. It can also help you to interpret Workload Activity reports from IBM RMF™ Post Processor and to report on the CPU consumption of different workloads.
