Data conversion
The data conversion (including calling any necessary exits) is performed by the distributed queuing facility when it puts a message to a destination queue that has XCF information defined for its storage class. Any exits needed must be available to the distributed queuing facility in the data set referenced by the CSQXLIB DD statement. This means that we can send messages to an IMS™ application using the WebSphere MQ-IMS bridge from any WebSphere MQ platform.
Because the WebSphere MQ-IMS bridge does not convert messages when it gets a message, messages arriving through the CICS distributed queuing facility are not converted.
If there are conversion errors, the message is put to the queue unconverted; this results eventually in it being treated as an error by the WebSphere MQ-IMS bridge, because the bridge cannot recognize the header format. If a conversion error occurs, an error message is sent to the z/OS console.
See Writing data-conversion exits for detailed information about data conversion in general.
