After you configure one machine to have a GlassFish domain, open the admin console at localhost:4848 and select “Clusters” and create a new one for example i88caCluster. Once that’s created, click the cluster you’ve just created, go to the “Instances” tab and create a new server instance such as i88caSrv1. Now we have a cluster with an instance, we can start the cluster from the cluster’s “General” tab. On the second machine, make sure GlassFish is installed and create another server as follows: asadmin --host <machine1> --port <admin port> create-local-instance --cluster i88caCluster i88caSrv2 When you invoke this command, the asadmin tool on the local machine doesn’t actually execute the command; it simply asks the asadmin tool on the remote machine you specify to execute it. So if you were to type “asadmin list-instances” afterwards on machine 2, the list would be empty even though a server instance physically resides on the machine. Running the same command on the machi...
