The programming for a CICS environment is standardized using the Command Level Interface. This allows to write operating system independent applications using an application programming interface that is portable between different platforms. But even when the API hides many of the system details from the application programmer it is still necessary to know the principles behind the various CICS commands to be able to use them efficiently. For a very long time CICS has been (and still is) the foremost transaction processing environment in the world. This is underlined by the many additional functions and features that have been added over the years. CICS is much more than handling "dumb" green screens - CICS includes distributed processing of requests, communication of applications across different platforms, and C2B (customer to business) and B2B (business to business) applications via the web.

CICS Application Programming:
Client/Server and other Advanced Functions & Facilities

Participants:

This course is intended for application programmers that have already some experience in CICS application programming. It is also helpful for system programmers that need an understanding how CICS applications interact with the CICS program.

Prerequisites:

Participants should have basic knowledge of CICS Systems, such as provided by the course C105E "CICS Application Programming: Introduction and Workshop".

Objectives:

After the completion of this course the participants will be able to use the advanced functions and facilities provided by the various CICS programming interfaces. They will know which performance-relevant parameters to use, and which other they should avoid. Finally, they will understand the reasons for certain design rules that are specified with this course.

Method:

Classroom lectures with many hand-on exercises
