Tips for troubleshooting

This section provides some tips that might assist you when troubleshooting problems.

Application tracing

You can install the MQSeries gateway with the -debug option, which causes debugging information to be written to the system event log. Using the Event Viewer, you can view the contents of the event log for possible causes to a problem. The Event Viewer is in the Administrative Tools folder of the Control Panel on a Windows platform.

Checking the event queue

Errors are either reported in the form of failed flows and messages which are logged to the integration broker log file, or written to the system event log on the MQSeries gateway machine. While investigating the problem, you should also examine the contents of the adapter event store to view possible erroneous events.

Loss of connection to the application

The connection to the application can only be lost if the MQSeries gateway queue manager is down. Always check the status of the queue manager, and if down, restart it to restore the connection to the application.
