I want to create a high avaliable messaging solution using a JBoss Messaging cluster, but now I'm confused: Suppose, I want a high available clustered messaging environment with MySQL persistency, I could create: - At least two JBoss Messaging nodes with a shared database. - A MySQL database with InnoDB tables because this is the only type that is supported. This would mean that the database is still a single point of failure. Therefore, I could create a MySQL cluster, but in that case I need the NDB-engine, which is not supported (http://wiki.jboss.org/wiki/JBossMessagingDatabaseCompatibilityMatrix) Pleas tell me that my conclusion "Creating a high available JBM solution is not possible at this moment using a MySQL backend" is not correct!
