I am upgrading JBoss from 4.0.5 to 4.2.3 and unable to set up clustering on the new version. I have spent quite a bit of time reading clustering FAQ and Wiki\JbossHA. I was unable to find a good TCP clustering example for 4.2.x. I have JBoss installed on 2 windows boxes and starting it with -c all. I cannot get the JGroups layer to work - nodes don't discover each other: the log on each box always show: 2008-11-05 15:40:07,263 INFO [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] Number of cluster members: 1 2008-11-05 15:40:07,263 INFO [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] Other members: 0 2008-11-05 15:40:07,263 INFO [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] Fetching state (will wait for 30000 milliseconds): 2008-11-05 15:40:14,326 INFO [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] State could not be retrieved (we are the first member in group) I am using TCP transport and my config in cluster-service.xml is like this: <TCP bind_addr="box1" start_port="7800" loopback="true" tcp_nodelay="true" recv_buf_size="20000000" send_buf_size="640000" discard_incompatible_packets="true" enable_bundling="false" max_bundle_size="64000" max_bundle_timeout="30" use_incoming_packet_handler="true" use_outgoing_packet_handler="false" down_thread="false" up_thread="false" use_send_queues="false" sock_conn_timeout="300" skip_suspected_members="true"/> <TCPPING initial_hosts="box1[7800],box2[7800]" port_range="3" timeout="3000" down_thread="true" up_thread="true" num_initial_members="3"/> <MERGE2 max_interval="100000" down_thread="true" up_thread="true" min_interval="50000"/> <FD_SOCK down_thread="true" up_thread="true"/> <FD timeout="10000" max_tries="5" down_thread="true" up_thread="true" shun="true"/> <VERIFY_SUSPECT timeout="1500" down_thread="false" up_thread="false"/> <pbcast.NAKACK max_xmit_size="60000" use_mcast_xmit="false" gc_lag="100" retransmit_timeout="300,600,1200,2400,4800" down_thread="true" up_thread="true" discard_delivered_msgs="true"/> <pbcast.STABLE stability_delay="1000" desired_avg_gossip="50000" down_thread="false" up_thread="false" max_bytes="400000"/> <pbcast.GMS print_local_addr="true" join_timeout="3000" down_thread="true" up_thread="true" join_retry_timeout="2000" shun="false" view_bundling="true"/> <pbcast.STATE_TRANSFER down_thread="true" up_thread="true" use_flush="true"/> Please help! A working config example for JBoss 4.2 would help a lot. Thank you, Alex View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4187126#...
