Data conversion in the MQI 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.

Data is converted on the client for IBM MQ Multicast traffic. If the MQGMO_CONVERT option is specified, data conversion is done as requested. User defined formats need the data conversion exit installed on the client; see Writing data-conversion exits for information about which libraries are now in the client and server packages.

For information about administering data conversion, see Enable data conversion for Multicast messaging.

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