The Wiki page (http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfiguringMultipleJBossInstance...) on this subject has been updated recently. My question relates to multiple instances that are to be members of the same cluster. Previously the Wiki page stated that it was advisable to wait 10-20 seconds between starting the first and second instances, otherwise there was a risk that the instances would consider themselves to be members of separate partitions. This text has been removed. Is this advice now obsolete? I have found that starting two or more JBoss instances simultaneously does not seem to be a problem: each instance considers itself to be the only member of the cluster initially, but they quickly discover each other and the partitions are merged. It would be good to get confirmation from whoever edited the Wiki page that this behaviour can be relied upon.
