Console Simulations


z/OS MVS                                              3 hours
JES2                                                       2 hours
VTAM                                                     2 hours
CICS                                                       2 hours
SHUTDOWN and IPL                            1 hour


These modularized simulations provide scenarios where MVS, JES, CICS and VTAM commands are required to analyze system component status, or attributes and resolve a problem. Required console responses during system shutdown and IPL are also covered.


Junior and senior operators responsible for monitoring z/OS system activity and resolving day-to-day z/OS system issues using console commands.  This course allows the student to practice entering commands and viewing responses.


Basic understanding of the z/OS Operating System or completion of the z/OS JES2, z/OS Communications and CICS courseware.


After completing this set of courses the student should be able to:

  • Enter z/OS MVS commands to maintain system integrity, monitor system and online functions, and identify and resolve system problems
  • Respond to messages displayed during z/OS IPL and shutdown
  • Enter CICS, VTAM, and JES2 commands to monitor and control elements associated with those environments
