IMS Interface

Substation ES IMS Interface connects TIBCO messaging applications and IMS applications in the z/OS environment.

  • Overview
    TIBCO messaging applications are normally the source of the external messages and requests that are received by Substation ES. Substation ES-to-Substation ES communication through the messaging layer can be another source for messages.
  • Architecture
    With Substation ES IMS Interface, external applications can communicate (publish, request, or reply) with transactions that are resident in the IMS Message Processing Program (MPP) regions.
  • Components
    Substation ES IMS Interface consists of the following components:
  • OTMA Super Members
    You can use Substation ES with OTMA super members as targets for regular messages, triggers and requests/replies.
  • Message Flow
    TIBCO application messages are transformed into requests with content and forwarded to Substation ES IMS Interface through XCF to the IMS OTMA server and, finally, to the IMS application for processing.
  • Communication Service Levels
    You can set different communication service levels as appropriate for communication between Substation ES IMS Interface and IMS applications.
  • OTMA Messages
    The communication data passed between the IMS Interface and the OTMA Server is within an OTMA message.
  • Message Size and Constructs
    IMS Interface messages include OTMA messages and application messages. Note the size of these messages.
  • Deployment
    You can deploy Substation ES and IMS Interface in various ways to meet system, application, and workload requirements.
  • Constraints
    Note the constraints of Substation ES IMS Interface.
