ABCs of z/OS System Programming, Volume 12
Installations today process different types of work with different response times. Every installation wants to make the best use of its resources, maintain the highest possible throughput, and achieve the best possible system responsiveness. You can realize such results by using workload management. This IBM® Redbooks® publication introduces you to the concepts of workload management utilizing Workload Manager (WLM). Workload Manager allows you to 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 the work. The system matches resources to the work to meet those goals, and constantly monitors and adapts processing to meet the goals. This reporting reflects how well the system is doing compared to its goals, because installations need to know whether performance goals are being achieved as well as what they are accomplishing in the form of performance goals.
