    Session replication using AS7 clustering, S3 PING, Amazon EC2

    H R Newbie

      Hello all,


      I am trying to setup session replication using AS7 clustering, S3 PING and Amazon EC2 for the Seam booking EAR app.


      So far, I have managed to get session replication working with two different local servers running on the same network using S3 ping and AS7:

      1. The S3 bucket is created with two files.
      2. I can restart one server and continue my browser session.

      I am running into a problem when trying to get this same setup running on Amazon EC2. Here's how far I could get on the Amazon cloud:

      1. I start JBoss using the following command:standalone.sh -c standalone-ha.xml -Djboss.server.base.dir=standalone -b 10.X.Y.Z -Djboss.default.jgroups.stack=tcp -Djboss.node.name=node1 &
      2. The S3 bucket is created with two files. Relevant part of standalone-ha.xml:                <protocol type="S3_PING">                    <property name="access_key">                        xxx                    </property>                    <property name="secret_access_key">                        xxx                    </property>                    <property name="prefix">                        jbossas7-s3ping                    </property>                    <property name="timeout">                        60000                    </property>                </protocol>
      3. JGroups logs says:09:59:23,254 INFO  [org.jboss.as.clustering.jgroups] (ServerService Thread Pool -- 37) JBAS010260: Activating JGroups subsystem.10:00:08,631 INFO  [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (pool-15-thread-1) ISPN000078: Starting JGroups Channel10:00:08,636 DEBUG [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (pool-15-thread-1) New view accepted: [node1/web|0] [node1/web]10:00:08,636 INFO  [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (pool-15-thread-1) ISPN000094: Received new cluster view: [node1/web|0] [node1/web]10:00:08,637 INFO  [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (pool-15-thread-1) ISPN000079: Cache local address is node1/web, physical addresses are []10:00:08,638 DEBUG [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (pool-15-thread-1) Waiting on view being accepted


      1. I have opened ICMP,TCP ports for EC2 Security Groups on both EC2 instances
      2. I have disabled firewall on both instances
      3. I can telnet from instance to the other on port 7600.
      4. I have attached my AS7 config.


      It seems like the two EC2 instances do not talk to each other. I can't find the following message in the EC2 logs:

      [org.jgroups.protocols.FD_SOCK] (Incoming-1,null) VIEW_CHANGE received: [node1/web, node2/web]


      Can anyone help?
