You shouldn't use the high performance journal with JDBC Master/Slave - http://activemq.apache.org/jdbc-master-slave.html with the journal and JDBC database - messages are stored in the journal - and only the references to those messages are stored in the journal - which would be local to the machine you are running the broker on. If you need performance - use a shared file system and KahaDB - http://activemq.apache.org/shared-file-system-master-slave.html
