After extensive research in the documentation and a lot of try and error, I really would appreciate your help. Any thoughts, hints, links are welcome!
We try to setup and run a Glassfish Domain Administration Server (DAS) with a cluster. The involved nodes are on different physical machines, but on the same network segment. On the instances of the cluster a JEE application is deployed, which makes use of the GF OpenMQ JMS implementation.
The instances run with embeded brokers in a conventional cluster. The setup involves instances locally on the DAS, as well as instances on a remote machine. One local instance with its embeded broker on the DAS we expect to be our master broker.
This setup is only fulfilled "by random" as we observed. There is a dependency on the startup order of instances to determine which instance gets to be the master broker. Is this behavior intentional?
Altough we could find lots of parameters to be configured in command line calls or configuration files in the documentation, we don't know exactly how to configure the cluster and broker settings correctly for the intended setting. Where and how (cli params, conf. files) should the involved settings (e.g. imq.cluster.masterbroker, imq.cluster.brokerlist) be configured?
In our try and error runs we setup 2 local instances on the DAS. Messages sent to the cluster were distributed between those 2 instances as expected. Messages were sent to the first local instance, which we expect to be the master broker. When we included a remote instance in the cluster no messages were consumed by the remote instance. Suprisingly after stopping and starting the first local instance, all instances (including the remote instances) consumed messages as expected. How is this behavior explained, respectively what is the suggested procedure to include instances (local or remote) in the cluster and make them work as expected?

Lots and pretty fundamental questions I guess, any help is very appreciated! Thanks!
