    Problem when configuring GossipRouter

    Younes Yahyaoui Novice

      Hello,

       

      i have tried to start a GossipRouter on a server1. Then i have tried to start a JBoss AS on another server. The GossipRouter don't react when strating the JBoss AS. An Error was throwed saying:

       

       

      2010-10-14 22:21:30,018 ERROR [org.jgroups.stack.GossipClient] exception connecting to host xxx.xxx.xxx.91:5555
      2010-10-14 22:21:30,018 ERROR [org.jgroups.protocols.TCPGOSSIP] [FIND_INITIAL_MBRS]: gossip client found no members
      

       

      I use SOA-P 4.3.0 (JBoss AS 4.4)

       

      • Support GossipRouter  an automatic discovery of Cluster members or only static (all members muss be present in the config of cluster.xml)?

       

      Any suggestions please?

       

      --Regards

          What stack you use? TCP or UDP? Besides this you don't have configured GossipRouter correctly. See documentation.

              Of course, but it needs to be properly configured.

                Thanks Marek for your answer,

                 

                i have tried to do what is writing in the documentation, but unfortunately without succes. I have started a GossipRouter under younes.cit.tu-berlin.de like this:

                 

                younes@younes:/$ java org.jgroups.stack.GossipRouter -port 5555 -bindaddress younes.cit.tu-berlin.de
                GossipRouter is starting...
                log4j:WARN No appenders could be found for logger (org.jgroups.conf.ClassConfigurator).
                log4j:WARN Please initialize the log4j system properly.
                GossipRouter started at Sat Oct 16 13:09:56 CEST 2010
                Listening on port 5555 bound on address younes.cit.tu-berlin.de/130.149.3.91
                
                
                younes@younes:/$ clear
                younes@younes:/$ java org.jgroups.stack.GossipRouter -port 5555 -bindaddress younes.cit.tu-berlin.de
                GossipRouter is starting...

                Then i have started a JBoss AS under another Node in the same network like using:

                 

                 

                younes@younes2:~/ESBCluster/jboss-soa-p.4.3.0/jboss-as/bin$ ./run.sh -b younes2.cit.tu-berlin.de -c all -Djboss.messaging.ServerPeerID=4 -Djboss.default.jgroups.stcak=tcp -g ClusterESB
                

                 

                I have recieved an error by node 2 saying:
                13:16:20,220 ERROR [GossipClient] exception connecting to host 130.149.3.91:5555
                

                I give additionnaly log.txt and cluster.xml (configuration for node2).
                Please help me. (can you please give me an example of how to configure GossipRouter in cluster.xml)
                I use Soa-p-4.3.0
                Thanks in advance

                  -Djboss.default.jgroups.stcak=tcp is misspelled, it needs to be
                  -Djboss.default.jgroups.stack=tcp

                  Did you change the "tcp" entry in  jgroups-channelfactory-stacks.xml to use TCP:TCPGOSSIP ?

                    Thanks Bela,

                     

                    i change the tcp entry in cluster.xml  ( i use JBoss AS 4.4: there is no jgroups-channelfactory-stacks.xml) to use:

                     

                     

                     

                     
                    <PING gossip_host="younesmysql.dyndns.org" gossip_port="5555" gossip_refresh="15000"
                                              timeout="2000" num_initial_members="3"/>     
                    
                    <PING gossip_host="younesmysql.dyndns.org" gossip_port="5555" gossip_refresh="15000"

                     

                                             timeout="2000" num_initial_members="3"/><PING gossip_host="younesmysql.dyndns.org" gossip_port="5555" gossip_refresh="15000"                           timeout="2000" num_initial_members="3"/>

                     

                     

                    The GossipRouter has reacted but unfortunately through an Exception saying:

                    I use JGroups-2.5.0.bin

                     

                    any idea please?

                     

                    • muss the GossipRouter work under port 5555 or can i use other port (e.g 8080)?

                     

                    Thanks

                      You need to use the same version of JGroups for the GossipRouter and the cluster nodes.

                       

                      GossipRouter can run under any open port

                        what is the difference between the two expressions??

                          jboss.default.jgroups.stcak vs jboss.default.jgroups.stack
