[jboss-as7-dev] Multiple HQ servers on the same AS instance

[Brian Stansberry]

Just an FYI for those interested in the HornetQ integration into the AS. 
I recalled this morning a call I was on a couple years back where an HA 
architecture was discussed based on two or more AS's w/ 2 HQ servers on 
each, one on each AS acting as backup to one on another. From chatting 
with Clebert today, it seems that architecture was implemented.

This has implications for the HQ integration in AS 7.1. Two support this 
kind of architecture, we'd need to:

1) Add a high level element in the jboss-as-messaging.xsd schema that 
encapsulates all the existing element and represents an HQ server.

2) Add a level to the messaging subsystem management resource tree for same.

3) Rework any HQ-related MSC service names to account for the 
possibility of multiple HQ servers.

4) Figure out an other issues this introduces as far as integrating with 
other services that depend on the messaging services.
