CICS System Administration (TD-CICSSA)

Audience

This course is intended for personnel responsible for IBM CICS administration, experienced application programmers, system programmers and managers.


Prerequisites

Delegates are expected to have prior CICS experience.


Duration

5 days. Hands on.

This course is available on site only. Please call for details.


Course Objectives

This course is designed to help CICS system administration personnel understand CICS from initialisation through to shutdown, including maintenance, performance and availability.

Upon completion of this course, attendees will appreciate how CICS works and be able to:

  • Start, run and shut down a CICS system.
  • Perform CICS administration duties.
  • Understand and work with resource naming conventions
  • Use CEDA, CEDB, and CEDC to manage CICS resources on-line.
  • Understand and maintain the System Initialisation Table parameters including those relating to performance.

A CICS 6.1 Lab System will be available for students.
