20.14.9. Deployments on HornetQ Backup Servers

In a dedicated HA environment, a JBoss EAP 6 server with HornetQ configured as a backup must not be used to host any deployments which use or connect to the HornetQ backup on that server. This includes deployments such as Enterprise Java Beans (Stateless Session Beans, Message Driven Beans), or servlets.
If a JBoss EAP 6 server has a HornetQ collocated backup configuration (where in the messaging subsystem there is a HornetQ server configured as 'live' and another HornetQ server configured as backup), then the JBoss EAP 6 server can host deployments as long as they are configured to connect to the 'live' HornetQ server.
