# Example of RED CICS Trigger

These IVP examples illustrate the RED CICS trigger process in delivering data from a CICS application to a TIBCO messaging application through Substation ES. The RED CICS Trigger can handle record sizes greater than 32,000 bytes up to maximum 4,096,000 bytes. These samples support guaranteed, reliable, and fire and forget delivery.

A CICS application initiates a request by linking to the SXCOTRED RED CICS Trigger module to write output data to the Substation ES COMMAREA or Containers (depending on the parameters passed in). Substation ES receives the trigger based on the Service Name parameter for this trigger process. The Substation ES Transformer then processes the data conversion according to the selected conversion rule in the trigger.

After the data has been converted, Substation ES publishes the output message to IVP Generic Listener.

For more information about the process flow, see "RED CICS Triggers" in the TIBCO Substation ES Operations and Administration manual.
