Hi, I'm a beginner with JBoss clustered configurations. 1 ) What would be te recommended approach for JGroups with JBoss AS clustered? TCP or UDP? 2) Two JBoss ASs in cluster are not supposed to work with reliable messages? So, why UDP came as default in JBoss? 3) On the other side UDP performs better. But, what can happen if packets are lost, unordered or duplicated. How can this affect JBoss AS behavior? Thanks.
