    Migrating from one node to others in planned downtime..

    ehskaga

      In JBoss cluster if there are some planned maintenance to be done on various nodes, how can it be achieved without interrupting the service.
      Is there a way by which we can migrate the services running on a node and stop any new request coming to that node so that the machine can be patched up for the maintenance activity and then restarted to re-join the cluster.

          If you use apache as front end, you could 'disable' a node using apache's 'status' webapp:
          http://localhost:8000/status/

            In most environments that I have worked in, simply removing the node from the cluster by shutting it down will create the desired effect. the user sessions should already be replicated to the other nodes in the cluster and apache will forward the users to the other node.
