The Connection Manager uses a model queue for creation of temporary dynamic queues, used for command processing and message retrieval. The default is SYSTEM.DEFAULT.MODEL.QUEUE. Rather than alter the system queue if some parameter customization is needed, you can create a custom model queue to be used instead, such as NASTEL.MODEL.QUEUE. This model can specify a larger MAXMSGL (for retrieving very large messages), higher MAXDEPTH (maximum messages), or other specific parameter values.
Enter the new queue name in the NASTEL.MODEL.QUEUE line in file [APWMQ_HOME]\config\groups\mqqual.ini. When the connection manager starts, it will check the qualifiers file and use that model queue instead of the default.
To configure mqqual.ini, copy the sample (mqqual.sam) and change the lines are noted above, remove any other sample lines in the file leaving a single line
