# 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.

The sample JCL stream is in the following:

Data Set: `USERHLQ.JCL`

Member: `SXRGILS`

Note: The `EXEC PARM - IVPNETW` is substituted with a set of TIBCO Rendezvous transport parameters. It is recommended that you use the provided default settings for all IVP runs. For details about the other settings, see the TIBCO Rendezvous Administration manual.

The message subjects to which the IVP Generic Listener subscribes are determined by the `SYSIN DD` statements, which start with the keyword SUBJECT followed by the subject name. There are up to three statement entries for the IVP Generic Listener.

## SYSIN Parameters

Following is a sample of the input control statements in the SYSIN parameter member:

      DEBUG    OFF
      subject  tibss.ivp.>
      subject  tibss.ibm.>
      UFLD-PFX tibss-
