Audience

This course is intended for:

• Trainee Programmers moving to online
• Anyone wanting a detailed overview of IBM CICS Facilities

Prerequisites

Attendees should be comfortable working with TSO/ISPF. Our z/OS TSO/ISPF Workshop is one way to gain this knowledge.

Duration

5 days. Hands on.

Course Objectives

This course provides an introduction to IBM CICS for version 6.1 and its Facilities and Functions.

The following are covered; Operator Interface, Intersystem Communication and how Resources are defined and managed. The course introduces the CICS RACF Security interface, Startup/Shutdown and Recovery, the CICS Explorer and CICS Web Services. The course also covers CICS support of external Databases such as DB2 and VSAM and the need for Data Integrity. In addition, the Attendee will learn how CICS Applications are designed and how CICS supplied Transactions assist the Programmer in Testing and Debugging.

Upon completion, attendees will have gained a good understanding of the role of CICS and be able to describe its basic architecture and its many services. A CICS 6.1 system will be available for Workshops and to reinforce the topics covered. This course is also available for previous CICS releases if required.
