Overview

This course presents the structure and control blocks of the z/OS BCP and system services. It prepares the new z/OS system programmer to identify potential bottlenecks and performance problems, perform initial error symptom gathering, and identify opportunities and requirements for tailoring a z/OS system. This course also provides prerequisite information needed for further training in specialized areas such as system measurement and tuning and system problem determination.

What You'll Learn

  • Explain the MVS functions and control blocks necessary to support a task in a multitasking and multiprocessing environment
  • Describe the software and hardware functions that allow a program to interact with programs running in other address spaces, use data in other address spaces, and use data in data spaces
  • Trace the flow of an I/O operation from the initial request in the application program through the completion of data transfer
  • Identify the control blocks that describe the current status of an I/O request
  • Describe the functions of the z/OS BCP Virtual, Real, and Auxiliary Storage Managers
  • Describe the functions performed by the Recovery Termination Manager and recovery management components to minimize failure impact and enhance error correction
  • Select the appropriate IBM publication to provide further technical information (SRLs, Technical Bulletins, Self-study and other z/OS courses)
  • Describe the services provided by cross system extended services (XES)
  • Identify and explain the purpose of the cache, list, and lock structures
  • Plan the implementation of the global resource serialization STAR environment.0.2 pref

Who Should Attend

The primary audience for this intermediate course are z/OS system programmers who are new to z/OS installation, customization, measurement and tuning, or problem determination. Subsystem programmers will also benefit from this class.

Prerequisites

  • Describe the following z/OS BCP (MVS) characteristics:
    • multiprocessing
    • multiprogramming
    • virtual storage and paging
    • and multiple address space/data space architecture
  • Explain how paging and swapping are accomplished through the interaction of real/central, expanded, auxiliary, and virtual storage in a z/OS system
  • Explain the role of the dispatcher, interrupts, SVCs, the program manager, and serialization in managing work in a z/OS system
  • State the role of z/OS software and hardware components in handling an I/O request for data on a direct access storage device

These prerequisites can be met through on the job training or completion of z/OS Facilities.

Note : A fundamental knowledge of hexadecimal notation, assembler language, z/Architecture instruction execution will enhance your understanding of the course material. Completion of Assembler Language Coding Workshop Assembler Language Series is recommended.
