Abstract
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 contents of the volumes are:
Volume 1: Introduction to z/OS and storage concepts, TSO/E, ISPF, JCL, SDSF, and z/OS delivery and installation
Volume 2: z/OS implementation and daily maintenance, defining subsystems, JES2 and JES3, LPA, LNKLST, authorized libraries, Language Environment, and SMP/E
Volume 3: Introduction to DFSMS, data set basics, storage management hardware and software, VSAM, System-managed storage, catalogs, and DFSMStvs
Volume 4: Communication Server, TCP/IP and VTAM
Volume 5: Base and Parallel Sysplex, System Logger, Resource Recovery Services (RRS), global resource serialization (GRS), z/OS system operations, automatic restart management (ARM), Geographically dispersed Parallel Sysplex (GPDS)
Volume 6: Introduction to security, RACF, Digital certificates and PKI, Kerberos, cryptography and z990 integrated cryptography, zSeries firewall technologies, LDAP, Enterprise identity mapping (EIM), and firewall technologies
Volume 7: Printing in a z/OS environment, Infoprint Server and Infoprint Central
Volume 8: An introduction to z/OS problem diagnosis
Volume 9: z/OS UNIX System Services
Volume 10: Introduction to z/Architecture, zSeries processor design, zSeries connectivity, LPAR concepts, HCD, and HMC
Volume 11: Capacity planning, performance management, RMF, and SMF
Volume 12: WLM
Volume 13: JES3
This IBM® Redbook provides an introduction to the concepts of worload manager (WLM).
Installations today process different types of work with different response times. Every installation wants to make the best use of its resources and maintain the highest possible throughput and achieve the best possible system responsiveness.
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 the work to meet its goal.
An installation should know what it expects to accomplish in the form of performance goals, as well as how important it is to the business that each performance goal be achieved. With workload management, you define performance goals for work, and the system matches resources to the work to meet those goals, constantly monitoring and adapting processing to meet the goals. Reporting reflects how well the system is doing compared to its goals. .
