Duration: 
4 days
Codes: 
CICS,CSP
Versions: 
NULL

Overview

Upon completion of this course, attendees will be able to:

  • Confidently install and customize a CICS Transaction Server system
  • Describe how CICS resources are defined and how CICS communicates with VTAM and TCPIP
  • Make use of the VSAM and DB2 interfaces as well as the Operational and Intersystem Communication Interfaces
  • Use the major CICS utilities
  • Describe the recovery methods available for CICS

A CICS/TS system will be available for online access during practical exercises, to support the material covered in lecture presentations.

Audience

This course is aimed at CICS systems programmers and technical CICS programmers who are new to the installation and tailoring of CICS Transaction Server.

Prerequisites

Delegates must be familiar with CICS architecture and CICS facilities and have a working knowledge of z/OS, JCL, TSO/ISPF, SNA concepts, VSAM concepts and Access Method services.

Thinking about Onsite?

If you need training for 3 or more people, you should ask us about onsite training. Putting aside the obvious location benefit, content can be customised to better meet your business objectives and more can be covered than in a public classroom. It's a cost effective option.

Submit an enquiry from any page on this site, and let us know you are interested in the requirements box, or simply mention it when we contact you.
