Installations today process different types of work with different completion and resource requirements. Every installation wants to make the best use of its resources and maintain the highest possible throughput and achieve the best possible system responsiveness. Workload management makes this possible.
With workload management, you define performance goals and assign a business importance to each goal. You define the goals for work in business terms, and the system decides how much resource, such as CPU and storage, should be given to it to meet the goal. Workload Manager will constantly monitor the system and adapt processing to meet the goals.
A new IBM Redbook, System Programmer's Guide to: Workload Manager, gives a broad understanding of the Workload Manager component of the z/OS system. It covers basic aspects of WLM together with the new functions available in the z/OS release up to z/OS 1.7. The book provides a discussion on how to create WLM policies based on business goals and the types of transactions you run in your systems.
This book also provides information on how to implement the WLM functions, in addition to suggestions on how to classify the different workloads to WLM so that it can best manage the different types of units of work. You will find information for effective performance analysis and a description of how to use the WLM functions to achieve a better throughput in your environment. This book also provides some best practice samples to better understand how to set up your classification and tune it.
