Using GlassFish 3.1.2.2 with 2 servers, 2 nodes, 2 instances and deployed
simple MDB to cluster (Conventional cluster with master broker). I can access
on server1 and server2 via port 23700. Shutdown server1 and try to access
from server2 and get *NAM1007 : Problem with membership change notification.
Exception occurred : java.lang.NullPointerException*. If I look at ports on
server2 23700 is not listening. I had to deploy an EAR with an MDB to get
server1 listening on the ORB ports. It appears that shutting down the master
broker gracefully also shuts down the ORB listeners of the other instances.
What happens if you want to do rolling maintenance? Second scenario, I
powered off master broker without GlassFish shutdown and ORB port stayed up
on server2, but after message was delivered it was not removed from the
queue. Stand alone client config:
System.setProperty("com.sun.appserv.iiop.endpoints","glassfish1.corp.local:23700,glassfish2.corp.local:23700");
System.setProperty("com.sun.iiop.loadbalancingpolicy", "ic-based");
System.setProperty("com.sun.corba.ee.transport.ORBWaitForResponseTimeout",
"5000");
System.setProperty("com.sun.corba.ee.transport.ORBTCPConnectTimeouts","100:500:100:500");
System.setProperty("com.sun.corba.ee.transport.ORBTCPTimeouts","500:2000:50:1000");
