Error handling and response messages

 

Messages sent to and by a broker are subject to exception processing, report generation and dead-letter queue processing in the same way as other WebSphere MQ messages. A message can indicate that a response is not required, is required only if there is an error, only if the command succeeds, or always required.

Response messages can be generated by the broker to each command message issued by a publisher or subscriber. Response messages indicate the success or failure of a request and also the reason for the failure. Responses are given only by the broker to which the messages are initially sent.

The following topics are discussed in this chapter:

• Error handling by the broker

• Response messages

• Broker responses

• Problem determination
