I've set up a cluster, with a DAS running on my MAC OS X host (JDK 1.6_26) and a second running in Oracle Linux (JDK 1.7.0.1) in a virtualbox instance (bridged networking).
I successfully create nodes and instances on the Oracle Linux host, and they register fine with the DAS. When I tail the DAS server.log while starting the instances, everything looks OK. Instances join the cluster. asadmin get-health shows two instances have started.
However, when I run "asadmin list-instances", it shows the instances as "not running". I've tried this with GlassFish 3.1.1 and GlassFish 3.1 (just in case). Same problem.
Any thoughts?
