Tutorial: IMS Support

This tutorial takes you step by step through the main features of Enterprise Developer and Enterprise Server IMS support. You start by importing an IMS demonstration application into Enterprise Developer, and finish by running the application on Enterprise Server while debugging the application in Enterprise Developer.
Note: You can follow this tutorial in lieu of performing the steps outlined in IMS Installation Verification Procedure (IVP), which effectively produces the same end result using the command line instead of the Enterprise Developer user interface.
Important: If you intend to complete the Interface Mapping Toolkit IMS Screen Tutorial , you must first complete this tutorial in its entirety before you begin the IMTK tutorial.

Prerequisites

To complete this tutorial, you need the following software in addition to Enterprise Developer:

  • Micro Focus Rumba+ Desktop TN3270 emulator, supplied with the Enterprise Developer installer.
    Note: If you did not choose to install Rumba+ Desktop when you installed Enterprise Developer, either uninstall and then rerun the installer with the Install Rumba option checked, or use an alternative TN3270 emulator. If you choose to use a different TN3270 emulator, be aware that all instructions in this tutorial assume that you are using the embedded Rumba+ Desktop emulator.

Demonstration Application

This tutorial uses the MFDEMO demonstration, located by default in the %PUBLIC%\Documents\Micro Focus\Enterprise Developer\Samples\Mainframe\IMS\Classic\IVP (for 32-bit) or IVP64 (for 64-bit) directory.

MFDEMO is a COBOL IMS TM application for creating and maintaining an IMS DB tabular database. User-defined tables are organized by table element within table name. The following components are used by this application:

IMS components:

  • DEMO03DD.DBD
  • DEMO03DD.DBU
  • DEMO001T.PSB
  • DEMO90.MFS
  • DEMO91.MFS
  • DEMO92.MFS
  • TRANCODE.TXT - IMS Stage 1 file

COBOL components:

  • DEMO001T.CBL
  • RGHTJUST.CBL

Outline

In this tutorial you perform the steps typically required in implementing and running IMS applications. Follow the steps in these topics in the order presented here:

  1. Create and Configure a Solution and Project
    Complete the steps required to create an Enterprise Developer solution and project, import the MFDEMO IMS application into the project, set the project properties, build the application, and perform additional required steps to enable the application to run in Enterprise Server.
  2. Configure IMS
    Register the resource definition file, load the IMS database, and import IMS transactions. These three procedures are required to successfully run and interact with an IMS application on Enterprise Server.
  3. Create and Configure an IMS Enterprise Server
    Create and configure an enterprise server region on which to run the MFDEMO IMS application.
  4. Run MFDEMO
    Walks you through the process of using the Rumba+ Desktop TN3270 emulator to run the MFDEMO application on the IMSDEMO enterprise server region.
  5. Debug MFDEMO
    Debug the MFDEMO application in Enterprise Developer.
