Other uses of message exits

 

Message exits can be used for reasons other than security. For example, a message exit can be used for application data conversion, although a data conversion exit is normally more appropriate for this purpose. They can be used for compressing and decompressing the application data in messages if the communications subsystem cannot provide this function. Headers in a message must not be compressed by a message exit because it causes data conversion of the message headers to fail.

Message exits also play an important role in implementing reference messages. Reference messages allow a large object, such as a file, to be transferred from one system to another without needing to store the object in a WebSphere MQ queue at either the source or destination queue manager. For more information about reference messages, see the WebSphere MQ Application Programming Guide.
