Enable data conversion for Multicast messaging
Use this information to understand how data conversion works for IBM MQ Multicast messaging.
IBM MQ Multicast is a shared, connectionless protocol, and so it is not possible for each client to make specific requests for data conversion. Every client subscribed to the same multicast stream receives the same binary data; therefore, if IBM MQ data conversion is required, the conversion is performed locally at each client.
In a mixed platform installation, it might be that most of the clients require the data in a format that is not the native format of the transmitting application. In this situation the CCSID and ENCODING values of the multicast COMMINFO object can be used to define the encoding of the message transmission for efficiency.
IBM MQ Multicast supports data conversion of the message payload for the following built in formats:In addition to these formats, we can also define your own formats and use an MQDXP - Data-conversion exit parameter data conversion exit.
For information about programming data conversions, see Data conversion in the MQI for multicast messaging.

For more information about data conversion exits and ClientExitPath, see ClientExitPath stanza of the client configuration file.
