IMS Database Application Programming (CM17G)

Overview

Learn how to write application programs that use Data Language One (DL/I) to process Information Management System (IMS) databases.

Audience

This is an intermediate course for individuals who write programs in Common Business Oriented Language (COBOL), or Programming Language One (PL/I), or Assembler language using DL/I to navigate through an process IMS databases.

Prerequisites

You should complete:

  • IMS Fundamentals (CM010) or IMS Fundamentals - Web - ILO(CMW01)

and a COBOL or PL/I language course, or be able to:

  • List the basic components of the IMS database system
  • Construct a non-DL/I application program in COBOL or PL/I

Objective

  • Describe the basic differences between files and IMS databases as they relate to application program coding and logic
  • Describe the terms and processing characteristics of IMS hierarchic data structures
  • Construct DL/I calls for either COBOL or PL/I language programs
  • Write, test and debug a batch application program that uses the DL/I call functions
  • Use the IMS Test Program to prototype application program calls, and to perform ad-hoc read and update access to an IMS database
  • Describe the applications and uses of other DL/I features
  • Program for recovery and restart using DL/I calls to establish synchronization points
  • Describe the functions provided by High Availability Large Database (HALDB), and any program differences when accessing a Full Function database or a HALDB
