Willem Noorduin [http://community.jboss.org/people/willemnoorduin] created the discussion "Hypersonic databases" To view the discussion, visit: http://community.jboss.org/message/636771#636771 -------------------------------------------------------------- We have implemented JBoss-clustering (JBoss 5.1.1.GA) with success, only to be production ripe, it is in general recommended to replace the Hypersonic Database with another (say Oracle or MySQL). The technical aspect is clear, just replace your hypersonic datasource with another JDBC Connector to DefaultDS and let JBoss take care of the rest. There are a few questions: * I have seen one Hypersonic database connection per JBoss profile. Does this mean we have to implement n seperated Oracle databases when we run n JBoss profiles, or can you do it per cluster (so, if 4 JBoss-profiles form a JBoss cluster, point these to the same Oracle database ? Notice I am using Oracle here because I want to stress the cost aspect, and yes, I know that MySQL won't cost you anything). * What information is saved to the database when you are using all the capacities of JBoss ? (I only saw one counter, but then again, I just ran some rediculously easy test application). -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/636771#636771] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
