I'm no glassfish expert or with oracle, but I'll share my experience on
clustering - Apache: How to avoid single point of failure ? We currently have
two load balancers with round robin DNS - Glassfish: - Is clustering the only
possibility to set-up load balancing? It really depends on your application
clustering helps distribute your app on instances and share session
information, if you don't need session sharing you can have several instances
of glassfish on different servers and that should work as well. - If I'm not
mistaking, there is only one domain, administrating and managing the several
instances, right? What happens if the node where the domain is running
crashes? Everything is down? How to avoid that? Passive domains on the other
nodes? if the node manager fails instances will still be running since they
don't depend on the DAS (Domain administration server) to be running - Is
there other point to consolidate? Don't know what you mean
