Labs – CICS (z/OS) 5.6


4 hours



The CICS labs provide a range of exercises that can be run in your organization’s mainframe training sandbox. Exercises focus on the tasks performed by CICS Administrators and Operators that include displaying CICS resources, system configuration and extracting and analyzing CICS statistics and performance data from SMF.


The initial two labs are suitable for operators and administrators that use CICS for monitoring and general troubleshooting, while other labs are suitable for CICS administrators who would need to manage CICS configuration and performance.


A solid understanding of z/OS  or the successful completion of the following Interskill courses:

  • CICS TS – CICS Transaction Server Introduction 5.6
  • CICS TS – Controlling CICS Transaction Server Operations 5.6
  • CICS TS – CICS Command Simulation 5.6

Each Lab module below contains its own list of prerequisites or equivalent knowledge, which is displayed when accessing the module.


After completing these labs, the student should be able to:

  • Interact with a CICS terminal session
  • Identify key CICS system initialization parameters
  • Display system and terminal information
  • Display details about group resources and list
  • Identify security configuration settings
  • Display information about resources using the main terminal transaction
  • Display and analyze CICS statistics and performance data
