Chapter 17. Running Multiple JBoss Enterprise SOA Platform Instances Side-by-Side

If you simultaneously launch multiple servers that each have the same database configuration, you may encounter errors. The server initialises a new database when it is launched with it for the first time. The problems can occur if more than one server attempts to do this simultaneously. To avoid this problem, launch one instance and wait until it has finished initializing the databases before starting the other instances. This only has to be done the first time that the servers are started.
