- slave) mode with KahaDB of both master and slave configured to a common NFS
mount or any common directory

2) Set the JMX property in both the broker as below

-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false" {code}
3) Start the broker with broker name as *master* so that it acquires a lock and
