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. -- Brian Stansberry Principal Software Engineer JBoss by Red Hat
