Troubleshooting event processing


Problem Potential solution / explanation
The connector delivers all messages with an MQRFH2 header. To deliver messages with only the MQMD WebSphere MQ header, append ?targetClient=1 to the name of output queue URI. For example, if you output messages to queue queue: //my.queue.manager/OUT, change the URI to queue: //my.queue.manager/OUT?targetClient=1. See Installing the connector for more information.
The connector truncates all message formats to 8-characters upon delivery regardless of how the format has been defined in the connector meta-object. This is a limitation of the WebSphere MQ MQMD message header and not the connector.
During pollForEvents, the connector shuts down after the following JMS exception is reported: MQJMS1000: Failed to create JMS message This error appears to relate to the MQ Java API and not the connector itself. It often occurs when running the connector on the same machine as the WebSphere Business Integration Message Broker product itself. To remedy the problem, you need to perform the following:
  1. Unzip the file Product_Dir\Dependencies\JRE_122_4.zip to folder Product_Dir\connectors\WBIMB\Dependencies\ jre_122_Rel4.
  2. Open Product_Dir\connectors\WBIMB\start_MQSIV2.bat and un-comment the following two lines:oset PATH=%CONNDIR%\Dependencies\jre_122_Rel4\bin...oset JAVA=%CONNDIR%\Dependencies\jre_122_Rel4\lib\rt.jar
  3. Restart the connector.
During pollForEvents, the connector shuts down after the following JMS exception is reported: MQJMS1052: Unrecognised [sic] JMS Message class This error can result from modifications made by WebSphere Business Integration Message Broker to a message originating from a JMS-compliant application. To correct this, remove remaining JMS information from problematic messages by adding the following SQL statement to a WebSphere Business Integration Message Broker compute node: SET OutputRoot.MQRFH2.jms = null;
