z/OS system anatomy part 2 - z/OS infrastructure & services

This five-day course, and its associated Part 1, together form the heart of RSM's definitive z/OS training curriculum for Systems Programmers.
In this second course attendees learn the functions of the major z/OS components in considerable detail. They will also learn how the interaction of job, task, storage and data management provides service to the end user. This is done by following the sequence of events as a unit of work passes through the z/OS system from initial submission to completion.

On successful completion of this course you will be able to:

  • describe the functions of MVS and JES2
  • use GRS effectively
  • exploit program management
  • explain how the dispatcher works
  • describe Cross Memory Services (XMS) and how it works
  • install user SVCs
  • describe how MVS invokes recovery and when to use ESTAE routines
  • explain how WLM works to manage z/OS resources
  • design and setup the DASD subsystem
  • isolate I/O problems.
