z/OS System Services Structure Training in Netherlands

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.

You should be able to:

• 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, and z/Architecture instruction execution will enhance your understanding of the course material. Completion of Assembler Language Coding Workshop or Assembler Language Series is recommended.

• 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
