IMS Transaction Manager (IMS TM) application programming

IMS TM is a transaction manager. It organizes and prioritizes incoming work that is represented by some input data stream (a “transaction”) from some device, processes that work, then sends a response back (usually) to the inputting source. Those devices that send input and receive responses had historically been limited to simple devices like green screen terminals or ATMs. However, currently most customers’ IMS systems process much of their work from transactions originating from a variety of devices such as smart phones.

Transaction message flow through the system

Use your COBOL or PL/I coding skills to build applications to process messages going to and from IMS TM. This course will show you how to use DL/I calls to access IMS.

What this course covers

If you are a COBOL or PL/I programmer and need to write applications for Information Management System™ (IMS), you’re in the right place. This intermediate course will show you how to write application programs that use DL/I to process terminal input and output messages in an IMS Transaction Manager (IMS TM) system.

Note that this course does not teach basic COBOL or PL/I. You should already have experience developing applications with one or both of those languages.

Who should take this course?

This course is for individuals responsible for writing programs in Common Business Oriented Language (COBOL) or Programming Language One (PL/I) using DL/I to communicate with terminals in an IMS TM system.

Prerequisites

You should have working knowledge and experience writing COBOL or PL/I applications for IMS Transaction Manager. You should be able to describe the basic control and flow of IMS TM (IMS/DC) communications facilities, understand the DL/I components and calls of a database application program, and modify a program in COBOL or PL/I to add IMS TM functions.

It is recommended that you take the IMS Fundamentals and IMS DB Application Programming courses or have equivalent knowledge.

Learning objectives

After completing this course, you should be able to:

Describe the objectives of a Transaction Manager
Describe the architecture of the IMS Transaction Manager
Construct DL/I calls to access the IMS Transaction Manager from COBOL or PL/I programs
Write, test, and debug a batch application programs that use DL/I calls to interface with the IMS Transaction Manager
Use the IMS Batch Terminal Simulator to test and debug programs that interface with the IMS Transaction Manager
Describe the applications and uses of other DL/I features
Program for recovery and restart by using DL/I calls
