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. The ABCs of z/OS® System Programming is a thirteen-volume collection that provides an introduction to the z/OS operating system and the hardware architecture. Whether you are a beginner or an experienced system programmer, the ABCs collection provides the information that you need to start your research into z/OS and related subjects. If you would like to become more familiar with z/OS in your current environment, or if you are evaluating platforms to consolidate your e-business applications, the ABCs collection will serve as a powerful technical tool.

The z/OS System Logger is a function provided by the operating system to exploiters running on z/OS. The number of exploiters of this component is increasing, as is its importance in relation to system performance and availability. This IBM Redbooks document provides system programmers with a solid understanding of the System Logger component and guidance about how it should be set up for optimum performance with each of the exploiters. System Logger is an MVS component that provides a logging facility for applications running in a single-system or multi-system sysplex. The advantage of using System Logger is that the responsibility for tasks such as saving the log data (with the requested persistence), retrieving the data (potentially from any system in the sysplex), archiving the data, and expiring the data is removed from the creator of the log records. In addition, Logger provides the ability to have a single, merged, log, containing log data from multiple instances of an application within the sysplex.

This IBM® RedpaperTM publication describes the concepts and functions of the IBM System Storage® DS8000® I/O Priority Manager. The DS8000 I/O Priority Manager enables more effective storage consolidation and performance management combined with the ability to align quality of service (QoS) levels to separate workloads in the system. With DS8000 I/O Priority Manager, the system can prioritize access to system resources to achieve the volume's desired QoS based on defined performance goals (high, medium, or low) of any volume. I/O Priority Manager constantly monitors and balances system resources to help applications meet their performance targets automatically, without operator intervention. Starting with DS8000 Licensed Machine Code (LMC) level R6.2, the DS8000 I/O Priority Manager feature supports open systems and IBM System z®. DS8000 I/O Priority Manager, together with IBM z/OS® Workload Manager (WLM), provides more effective storage consolidation and performance management for System z systems. Now tightly integrated with Workload Manager for z/OS, DS8000 I/O Priority Manager improves disk I/O performance for important workloads. It also drives I/O prioritization to the disk system by allowing WLM to give priority to the system's resources automatically when higher priority workloads are not meeting their performance goals. Integration with zWLM is exclusive to DS8000 and System z systems. The paper is aimed at those who want to get an understanding of the DS8000 I/O Priority Manager concept and its underlying design. It provides guidance and practical illustrations for users who want to exploit the capabilities of the DS8000 I/O Priority Manager.
