IMS Transaction Manager Application Programming (CM18G)

Overview

Learn how to write application programs that use Data Language One (DL/I) to process terminal input and output messages in an Information Management System / Data Communications (IMS/DC) system.

Audience

This intermediate 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/DC system.

Prerequisites

You should:

  • complete:
    • IMS Fundamentals (CM010) or IMS Fundamentals -Web (CMW01)
    • IMS DB Application Programming (U3717)
  • or be able to:
    • Describe the basic control and flow of IMS/DC communications facilities
    • Understand the DL/I components and calls of a database application program
    • Modify a program in COBOL or PL/I to add IMS/DC functions

Objective

  • Modify an IMS batch DL/I application program to function in an IMS/DC environment: receiving a message from a terminal and sending output messages to terminals
  • Handle the exception conditions that may occur using DL/I functions
  • Work with Scratch Pad Areas (SPA) in an IMS-conversational program
  • Understand the application program considerations in using Message Format Services (MFS) and the system service functions data structures
