-------------------------------------

             Summary: Server stops after switching from 'local' DC to 'remote' DC
                 Key: WFCORE-4733
                 URL: https://issues.jboss.org/browse/WFCORE-4733
             Project: WildFly Core
          Issue Type: Bug
          Components: Management
    Affects Versions: 10.0.0.Final
         Environment: 2 servers started as DC on two different machines
            Reporter: Joerg Baesner
            Assignee: Jeff Mesnil


Install WildFly on two different machines, add an 'admin' user and start the {{host-master.xml}} configurations on each node, like:

machineA: (10.10.10.1)
{noformat}
$JBOSS_HOME/bin/add-user.sh -u admin -p admin
$JBOSS_HOME/bin/domain.sh --host-config.xml -Djboss.bind.address.management=10.10.10.1
{noformat}

machineB: 10.10.10.2
{noformat}
$JBOSS_HOME/bin/add-user.sh -u admin -p admin
$JBOSS_HOME/bin/domain.sh --host-config.xml -Djboss.bind.address.management=10.10.10.2
{noformat}

And then applying a simplified script like below to machineB:

{code}
batch
/host=master:write-attribute(name=name, value=slave)
/host=master/core-service=discovery-options/static-discovery=primary:add(host=10.10.10.1, port=9990, protocol=remote+http)
/host=master:write-remote-domain-controller(username=admin, security-realm="ManagementRealm")
/host=master/core-service=management/security-realm=ManagementRealm/server-identity=secret:add(value="YWRtaW4=")
run-batch

/host=master:reload
{code}

Executing this scripts results in a server log output like below and stopping of the 'DomainController':
