CICS for System Programmers

Code: CICSSP

Description

This CICS course covers the latest version of 6.1. Upon completion, attendees will be able to confidently install and customize a CICS Transaction Server system.

Audience

This course is aimed at:

  • CICS Systems Programmers
  • Technical CICS Programmers needing a better understanding of CICS

Prerequisites

Ideally attendees should have one or two years experience supporting CICS Transaction Server.

Objectives

This CICS course covers the latest version of 6.1.

Upon completion, attendees will be able to confidently install and customize a CICS Transaction Server system. They will be able to describe how CICS resources are defined and how CICS Communicates with VTAM and TCPIP. The attendee will understand the VSAM and DB2 interfaces as well as the Operational and Intersystem Communication Interfaces. The major CICS Utilities are also covered as is Recovery and Logging. The attendees will also be able to describe the CICS-MQ Interface, Threadsafe and understand what is available for Problem Determination. There is also an introduction to CICS Web Services.

A CICS 6.1 system will be available for online access and workshops. This course is also available at previous releases, please ask for details.
