I'm trying to setup a pure master slave configuration. Startup looks fine,
but if the master stops, the slave also stops. I would have expected it to
stay up. Below are the configs and relevant part of the slave log file. Any
guidance is greatly appreciated.
thanks
sam
Master config:
<broker xmlns="http://activemq.apache.org/schema/core";
brokerName="master">

<!-- The store and forward broker networks ActiveMQ will listen to
-->
<networkConnectors>
<networkConnector name="mynetwork"
uri="static://(tcp://localhost:61616)"/>
</networkConnectors>
<persistenceAdapter>
<amqPersistenceAdapter syncOnWrite="false"
