    Jboss HornetQ Failover in different clustered machines (Virtual machines)

      Hi,

       

      I need to implement hornetQ with failover for Jboss AS 7.2 (HornetQ: 2.3.0 CR1).

       

      I was able to successfully implement it in the same machine with two different copies of Jboss.

       

      But put  my backup server in a VM there are some problems.

       

      These are the steps that happens

       

      Live server up - OK

      Back up server up - OK - "backup announced" log message is there

      Live server shutdown. My queues are deployed in backup server and backup log says "Backup Server is now live"

      Client tries to publish messages - Publisher does nothing. (No error or anything).

      (This same steps worked fine when I had both live and back up instances in the same PC (which is a Virtual machine))

       

      I have attached my standalone-config xmls from back up and live servers.

      Difference between working configurations in the same machine VS different machines is that I have added <param key="host" value="LIVESERVER"/> to backup server acceptor and connector, because I initially got some errors

       

      Both were VMs are windows server 2012. I started my servers as follows

      Live: standalone.bat --server-config=standalone-full-ha.xml -Djboss.bind.address=0.0.0.0 -Djboss.node.name=jl1

      Backup: standalone.bat --server-config=standalone-full-ha.xml -Djboss.bind.address=0.0.0.0 -Djboss.node.name=jbu1

       

      Key snippets from the log file

       

      This is same for both live and backup

      Live server

       

                    <connectors>
                    <netty-connector name="netty" socket-binding="messaging">
                    </netty-connector>
                    <netty-connector name="netty-throughput" socket-binding="messaging-throughput">
                        <param key="batch-delay" value="50"/>                    
                    </netty-connector>
                    <in-vm-connector name="in-vm" server-id="0"/>                
                </connectors>
                <acceptors>
                    <netty-acceptor name="netty" socket-binding="messaging">
                    </netty-acceptor>
                    <netty-acceptor name="netty-throughput" socket-binding="messaging-throughput">
                        <param key="batch-delay" value="50"/>
                        <param key="direct-deliver" value="false"/>
                    </netty-acceptor>
                    <in-vm-acceptor name="in-vm" server-id="0"/>                
                </acceptors>

       

      Backup server

       

        <connectors>
                    <netty-connector name="netty" socket-binding="messaging">
  <param key="host" value="LIVESERVER"/>
  </netty-connector>
                    <netty-connector name="netty-throughput" socket-binding="messaging-throughput">
                        <param key="batch-delay" value="50"/>
                    </netty-connector>
                    <in-vm-connector name="in-vm" server-id="0"/>
                </connectors>
                <acceptors>
                    <netty-acceptor name="netty" socket-binding="messaging">
  <param key="host" value="LIVESERVER"/>
  </netty-acceptor>
                    <netty-acceptor name="netty-throughput" socket-binding="messaging-throughput">
                        <param key="batch-delay" value="50"/>
                        <param key="direct-deliver" value="false"/>
                    </netty-acceptor>
                    <in-vm-acceptor name="in-vm" server-id="0"/>
                </acceptors>

       

       

      Any help is appreciated.

      (I'm not in a position to use latest versions in EAP 6, Wildfly etc because our jboss version is already been in user for a long time now)
