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"

<MERGE2 max_interval="100000"

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
