EAP 6 Administration and Configuration Guide - HornetQ Message Replication - https://access.redhat.com/documentation/en-US/JBoss_Enterprise_Application_Platform/6.4/html/Administration_and_Configuration_Guide/sect-High_Availability.html#HornetQ_Message_Replication

Internal

Overview

For high availability purposes, the live server and the backup server must be installed on two separated physical (or virtual) hosts, provisioned in such a way to minimize the probability of both host failing at the same time.

JMS Connection Factories and JMS Destinations on the Backup Server

A backup HornetQ instance does not need the <jms-connection-factories> and <jms-destinations> sections as any JMS components are created from the shared journal when the backup server becomes live.
