[Clustering/JBoss] - Farm Deployment with UDP not working
by RedChili
Hi,
I have a clustered JBoss environment consisting of several nodes. All nodes are absolutely identical in their configuration and form a cluster "DefaultPartition". Joining and leaving the cluster works fine.
I've also established the farming deploy service but this farming service only works when I use the TCP configuration in cluster-service.xml.
My problem looks similar to this one:
http://www.jboss.com/index.html?module=bb&op=viewtopic&t=90561&postdays=0...
However as I'm using 4.2.0CR1 the buffer sizes are already increased and don't seem to be the problem.
Using UDP Protocol I deploy an application on one node, this node starts the application just fine and then "hangs" on deploying it to the cluster:
14:43:00,210 INFO [ClusterFileTransfer] Start push of file kusssdemo.ear to cluster.
It hangs there forever and nothing happens on the other nodes.
The UDP configuration is as follows:
<Config>
| <UDP mcast_addr="${jboss.partition.udpGroup:228.1.2.3}"
| mcast_port="${jboss.hapartition.mcast_port:45566}"
| tos="8"
| ucast_recv_buf_size="2000000"
| ucast_send_buf_size="640000"
| mcast_recv_buf_size="2500000"
| mcast_send_buf_size="640000"
| loopback="false"
| discard_incompatible_packets="true"
| 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"
| enable_bundling="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"/>

| <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>
|
The working TCP config looks like:
<Config>
| <TCP bind_addr="${jboss.bind.address}" start_port="7800" loopback="true"
| tcp_nodelay="true"
| recv_buf_size="20000000"
| send_buf_size="640000"
| discard_incompatible_packets="true"
| max_bundle_size="64000"
| max_bundle_timeout="30"
| use_incoming_packet_handler="true"
| use_outgoing_packet_handler="false"
| down_thread="false" up_thread="false"
| enable_bundling="false"
| use_send_queues="false"
| sock_conn_timeout="300"
| skip_suspected_members="true"/>
| <TCPPING initial_hosts="192.168.1.106[7800],192.168.1.105[7800]" port_range="3"
| timeout="3000"
| down_thread="false" up_thread="false"
| num_initial_members="2"/>
| <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"/>
| <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"/>
| <pbcast.STATE_TRANSFER down_thread="false" up_thread="false" use_flush="false"/>
| </Config>
|
In addition tho this question: what is the initial_hosts parameter in the TCP config for? Do I have to specify all potential cluster nodes in this list? Or can i use something like {jboss.bind.address}[7800] there?
Thanks,
Reinhard
