I'm working through a plan to migrate our apps to Glassfish and am planning on using a clustered profile. I have a couple questions about clusters in Glassfish and how the failover works in a cluster. From what I understand, if an instance of a cluster goes down the app will failover into another instance (to set this up do I need to enable and configure the load balancing in Glassfish?). But what happens if the DAS goes down? Will all apps become unavailable? If so, is there a way to failover when the DAS goes down?
