Hi,
Make sure you are configuring the MBMonitor10.properties file for IIB10 and that you have set the <brokername>.broker.configfile property to point to an actual broker file for your IIB. For example, for a broker named "iib10broker1", you would have Broker connection entry that looks something like this:
iib10broker1.channelname=QM1_Channel
iib10broker1.host=QM1.foo.com
iib10broker1.queue.manager=QM1
iib10broker1.port=1414
iib10broker1.broker.configfile=iib10broker1.broker
The iib10broker.broker file should be in the same directory as the MBMonitor10.properties file (unless you specify a path above) and should set the "host", "listenerPort", "userName", and "password" to connect.
That should let the MBMonitor find the connection info to the IIB.
Cheers,
Neil
