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.

This volume describes the basic system programming activities related to implementing and maintaining the z/OS installation, and provides details about the modules used to manage jobs and data. The topics covered are:


  • Overview of the parmlib definitions and the IPL process. The parameters and system data sets necessary to IPL and run a z/OS operating system are described, along with the main daily tasks for maximizing performance of the z/OS system.
  • Basic concepts related to subsystems and subsystem interface, how to use the subsystem services provided by IBM® subsystems.
  • Job management in the z/OS system using the job entry subsystems JES2 and JES3. Detailed discussion of how JES2 and JES3 are used to receive jobs into the operating system, schedule them for processing by z/OS, and control their output processing.
  • The link pack area (LPA), LNKLST, authorized libraries, and the role of VLF and LLA components.
  • System Modification Program/Extended (SMP/E)
  • Language Environment®

The other volumes contain the following content:
Volume 1: Introduction to z/OS and storage concepts, TSO/E, ISPF, JCL, SDSF, and z/OS delivery and installation
Volume 3: Introduction to DFSMS, data set basics storage management hardware and software, catalogs, and DFSMStvs
Volume 4: Communication Server, TCP/IP, and IBM VTAM®
Volume 5: Base and IBM Parallel Sysplex®, System Logger, Resource Recovery Services (RRS), global resource serialization (GRS), z/OS system operations, automatic restart management (ARM), IBM Geographically Dispersed Parallel Sysplex™ (IBM GDPS®)
Volume 6: Introduction to security, IBM RACF®, Digital certificates and PKI, Kerberos, cryptography and z990 integrated cryptography, zSeries firewall technologies, LDAP, and Enterprise Identity Mapping (EIM)
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 IBM z/Architecture®, the IBM Z platform IBM Z connectivity, LPAR concepts, HCD, and DS Storage Solution.
Volume 11: Capacity planning, performance management, WLM, IBM RMF™, and SMF
Volume 12: WLM
Volume 13: JES3, JES3 SDSF
