eXchange Integrator Standard Error-Handling Topics

System-level errors, and business errors that cannot be handled by message tracking, are considered faults; eXchange Integrator catches such faults and publishes the ExStdEvent — with the error information now contained inside the ExStdEvent — to a standard eXchange Integrator topic, EX_ERROR. If further processing is possible, the messages are finally published to the EX_PROCESSEDERRORS topic; otherwise, they are finally published to the EX_DEADLETTER topic.

EX_PROCESSEDERRORS

When EX_ERROR contains a marshallable ExStdEvent message, the message is presumed to contain all necessary troubleshooting details, specified in a clear enough way to allow the fault to be diagnosed. In this case, the ExStdEvent is published to the EX_PROCESSEDERRORS topic.

EX_DEADLETTER

When EX_ERROR contains an ExStdEvent message that cannot be unmarshaled, there is no way to determine the cause of the fault. In this case, the ExStdEvent is published to the EX_DEADLETTER topic.
