Substation ES Communication Programs

This section describes the generic IVP components in Substation ES.

  • Rendezvous IVP Sender Listener
    The program SXR3ISL1 works as a TIBCO messaging requestor application. It publishes Substation ES IVP requesting messages based on a set of parameters passed in through SYSIN DD statements in the run JCL and then waits for a reply from Substation ES.
  • Enterprise Message Service IVP Sender Listener
    The program SXJ3ISL1 works as a TIBCO messaging requestor application. It publishes Substation ES IVP requesting messages according to a set of parameters passed in through SYSIN DD statements in the run JCL, then waits for a reply from Substation ES.
  • IVP Request or Reply EMS Consumer Producer
    The program SXJ3RRCP works as a TIBCO messaging transactional server application.
  • IVP Generic Listener
    The program SXR3ILS1 works as a TIBCO messaging subscriber application. It receives all IVP messages published from the Substation ES region. The messages originate from the TIBCO messaging requestor applications.
  • IVP IMS Conversational Sender or Listener
    The program SXR3ICV1 works as a TIBCO messaging transactional client application. The Conversational Sender or Listener publishes Substation ES IMS Conversational IVPs requesting messages. Which messages are requested depends on a set of parameters passed in through SYSIN DD statements in the run JCL.
  • IVP Generic Error Listener
    The programs SXR3IELS and SXJ3IELS initiate a TIBCO messaging subscriber that receives error messages published by Substation about data transformation errors, warnings, and error conditions encountered during Substation ES IVP’s runtime processing.
