This is the definitive administration course for all those who have responsibility for CICS administration on CICS/TS systems.

At the end of the course, the student should have a good understanding of the workings of CICS and be able to:

  • Perform all CICS administration duties;
  • Use CEDA transaction to dynamically define resources;
  • Understand resource naming conventions;

Intended for

This administration class is designed for the person who has responsibility for, or interest in CICS administration.

Background

Basic CICS experience (at least equivalent with the contents of CICS concepts).

Training method

The course combines formal tuition with a series of practical exercises. Over the course of the week attendees build and operate a CICS/TS system from scratch.

Attendees are encouraged to bring along the System Initialization Table macros and Overrides for a couple of production CICS regions - If Transaction Routing and/or Function Shipping is being used then a SIT and Overrides for a TOR, AOR and DOR would be welcome.

Course leader

RSM Technology.

Duration

5 days.
