# Customizing Messaging Connectivity

To ensure the communication between TIBCO Substation ES and TIBCO Rendezvous or TIBCO EMS, you have to customize the messaging connectivity depending on which TIBCO messaging protocol you use.

## Customizing TIBCO Rendezvous Connectivity

If the default ESB endpoint settings for TIBCO Rendezvous in Substation ES are not appropriate for your environment, you can modify the settings in the Transformer DCUI panels for defining ESB endpoint entities.

For details, see the TIBCO Substation ES Configuration and Resources manual.

The default values supplied by Substation ES are '-service 7555 -network 127.0.0.1'. They imply that you are running a daemon (RVD or RVRD) on the same subnet with the default Rendezvous port 7500.

## Customizing TIBCO EMS Connectivity

You must change the supplied default ESB endpoint settings in Substation ES for TIBCO EMS to match your environment. You can modify these settings in the Transformer DCUI panels for defining ESB endpoint entities.

For details, see the TIBCO Substation ES Configuration and Resources manual.

The default configuration supports a fault-tolerant EMS server pair, which runs in environments in which the EMS server is supported.

Substation ES uses the TIBCO EMS connection factory for all EMS connections. For information on how to implement Auto Reconnect, see "Using Connection Factories" in the TIBCO Substation ES Configuration and Resources manual.
