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?
No. If DAS is not available (crashes or is stopped), then the cluster
still continues to serve apps.
