1. Re: Clustering Problem
andre1001 Aug 7, 2007 3:49 PM (in response to sudya)Same problem.
I've been trying with JBoss 4.2.1 and Windows XP with "-b 0.0.0.0" startup configuration. I've also tried to change loopback parameter, but without success.- On Windows machines, because of the media sense feature being broken with multicast (even after disabling media sense) set the UDP protocol's loopback attribute to true --> <Config> <UDP mcast_addr="${jboss.partition.udpGroup:228.1.2.3}" mcast_port="${jboss.hapartition.mcast_port:45566}" tos="8" ucast_recv_buf_size="20000000" ucast_send_buf_size="640000" mcast_recv_buf_size="25000000" mcast_send_buf_size="640000" loopback="true" 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" ip_ttl="${jgroups.udp.ip_ttl:2}" down_thread="false" up_thread="false"/> <PING timeout="2000" down_thread="false" up_thread="false" num_initial_members="3"/> <MERGE2 max_interval="100000" down_thread="false" up_thread="false" min_interval="20000"/> <FD_SOCK down_thread="false" up_thread="false"/> <FD timeout="10000" max_tries="5" down_thread="false" up_thread="false" shun="true"/> <VERIFY_SUSPECT timeout="1500" down_thread="false" up_thread="false"/> <pbcast.NAKACK max_xmit_size="60000" use_mcast_xmit="false" gc_lag="0" retransmit_timeout="300,600,1200,2400,4800" down_thread="false" up_thread="false" discard_delivered_msgs="true"/> <UNICAST timeout="300,600,1200,2400,3600" down_thread="false" up_thread="false"/> <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="false" up_thread="false" join_retry_timeout="2000" shun="true" view_bundling="true"/> <FRAG2 frag_size="60000" down_thread="false" up_thread="false"/> <pbcast.STATE_TRANSFER down_thread="false" up_thread="false" use_flush="false"/> </Config>

2. Re: Clustering Problem
atomicgun Aug 8, 2007 12:06 AM (in response to sudya)maybe you tried to start 2 server at the same time, so they can't see each other...
I have a problem also, let's say i have node A and B seeing each other as cluster members, and i tried to shutdown A, B will take-over and the failover works. but when i tried to restart A, A cannot detect B as member and discarding messages from B. then i stopped B, waited for a while and restart B again, this time A and B can see each other as cluster members. any idea? is there any priority when forming a cluster group??
i just implemented the most basic Apache Web server and load-balance A and B using mod_jk
