Subject Re: Artemis 2.0 cluster fail over issue

I'm confused. You say, "looks like UDP is allowed," and then you say, "it looks like the
would not be able to send." Then you attached some screen shots of what looks like some kind
of administration console that I don't recognize. So is UDP multicast supported in your cloud
environment or not? A simple yes or no will suffice.

At this point I'm not sure I can provide the kind of help you need so I'll just say a few
things in the hope that they'll be productive:

  1) Most cloud environments don't support UDP multicast so configuring your cluster to use
UDP multicast in a cloud environment is likely to result in a broken cluster.
  2) If your cloud environment doesn't support UDP multicast then you can either use static
clustering or JGroups. You can see examples of these configuration in the "clustered-static-discovery"
and "clustered-jgroups" examples respectively.

Hmm I had to verify to configuration looks like UDP is allowed:

I'm not an expert on IP but it looks like the would not be able to
send out to the server.
