Subject Re: some broker can't join network of brokers
Date Fri, 09 Jul 2010 09:22:18 GMT

b2,b3,b4 have the same broker name 'dynamic-broker1', b1 and b5 get the
broker name 'dynamic-broker1', if they all use the same broker name, the
situation is the same, I have test it.

<broker xmlns="http://activemq.apache.org/schema/core"
brokerName="dynamic-broker2" dataDirectory="${activemq.base}/data">
