Creating and Configuring an Enterprise Server Region for IMS

To run IMS applications, you must create an enterprise server region that is MSS-enabled and appropriately configured to run an IMS application. You can do this either from the Visual Studio IDE or Enterprise Server Administration. When you create the enterprise server region from the Visual Studio IDE, much of the configuration is done for you; however, both methods require manual configuration as well.

Creating an enterprise server region from Visual Studio using the IMS Template

Enterprise Developer provides an Enterprise Server template, IMSTemplate.xml, that you can use to simplify the process of creating and configuring an enterprise server region for an IMS application. IMSTemplate.xml is located in VSInstallDir\Common7\IDE\Extensions\Micro Focus\Enterprise Developer\1.0\Etc\ServerTemplates by default. When you use the template to create the enterprise server region, the following is enabled or configured for you automatically based on your Enterprise Developer project properties and the information you supply when creating the enterprise server:

Default configuration for an IMS-enabled enterprise server region:
  • MSS is enabled
  • IMS is enabled
  • System Initialization Table is set to IMSSIT
  • Message processing region (MPR) is created
Configuration based on information required by the template:
  • Enterprise server region name
  • Project is associated with the enterprise server region
  • Working mode, 32- or 64-bit
Configuration based on Enterprise Developer project properties:
  • Application path
  • Configuration directory
  • Database path
  • GEN file directory
  • Map/MFS path
  • Transaction path

You must manually specify a TN3270 listener and port number.

Creating and configuring an enterprise server region from Enterprise Server Administration

When you create an enterprise server region from Enterprise Server Administration with the intent to run an IMS application on the enterprise server, you must configure the following as a minimum:

When initially creating the enterprise server region, specify:
  • A name for the enterprise server region
  • Mainframe Subsystem Support
  • Working mode, 32- or 64-bit
  • Specify a TN3270 listener and port number
Manually configure the following:
  • Enable IMS
  • Specify a System Initialization Table (SIT)
  • Specify the location of:
    • Application files
    • Database files
    • Generated files
    • Maps/MFS files
    • Transaction files
  • Specify a message processing region (MPR)
