Messages sent across a IBM WebSphere MQ link are not delivered - Middleware News

Note: Error messages appear in the SystemOut.log file or, if you have turned on tracing, in the trace.log file. You can also look for equivalent messages in the WebSphere MQ error logs (or trace files if you have turned on tracing in the WebSphere MQ network).
  1. If you are sending messages from a service integration bus to a WebSphere MQ network, it is possible that the messages are stored on the service integration bus and waiting to be delivered, but that the WebSphere MQ link sender channel has not been started or is in a retry state. Verify that the WebSphere MQ link sender channel is started and in running state.
  2. If you are sending messages from a WebSphere MQ network to a service integration bus, it is possible that the messages are stored on the transmission queue in the WebSphere MQ network and waiting to be delivered, but that the sender channel in the WebSphere MQ network has not been started or is in a retry state. Verify that the sender channel in the WebSphere MQ network is started and in running state.
  3. It is possible that the messages could not be processed or delivered to the target destination and hence they have been placed either on an exception destination on the service integration bus, or on the dead letter queue in the WebSphere MQ network. Verify that the WebSphere MQ Link on the messaging engine is configured properly with the correct foreign bus, queue manager name (service integration bus), sender channel and receiver channel. The sender channel on the WebSphere MQ Link should match the receiver channel on WebSphere MQ. The receiver channel on the WebSphere MQ Link should match the sender channel on WebSphere MQ.Look for messages CWSIC3096I, CWSIC3098I, CWSIC3200E, CWSIC3209E.
    Check the exception destinations and the dead letter queue. It is possible that the target destination has not been defined, or is full in which case, determine why messages are not being processed from the target destination.
  4. It is possible that the target destination and the exception destination and/or the dead letter queue are full and that subsequent persistent messages cannot be safely delivered. Under these circumstances the channel is stopped to avoid any loss of messages. Look for message CWSIP0291W.
    Determine why messages are not being processed from the target destination.
  5. It is possible that the target destination and the exception destination and/or dead letter queue are full and that subsequent nonpersistent messages are discarded. Check the persistence of messages being generated by your applications.
  6. It is possible that the channel has stopped because the remote system cannot accept messages for some reason. Look for message CWSIC3080E.
