CICS Web Enablement

Prerequisites:

The participant should have a sound understanding of the CICS environment. Some internet experience would be advantageous but is not essential.

Course Description:

This course is designed for students wanting to know more about the CICS Web Services and the facilities they offer, including how to code, manage, plan for and develop standards.

Delegates will be able to code the programming changes required to run 3270 based transactions from the Internet/Intranet and to code new Web aware programs using the CICS WEB and DOCUMENT API.

This course includes the following modules:
