A couple of questions on which configs to change. My current jgroups settings in
cluster-service looks like:
<!-- Name of the partition being built -->
ProductionPartition
<!-- Determine if deadlock detection is enabled -->
False
<!-- The JGroups protocol configuration -->
<!-- UDP: if you have a multihomed machine,
set the bind_addr attribute to the appropriate NIC IP address -->
<!-- UDP: On Windows machines, because of the media sense feature
being broken with multicast (even after disabling media sense)
set the loopback attribute to true -->
<UDP mcast_addr="228.1.2.3" mcast_port="45566"
ip_ttl="64" ip_mcast="true"
mcast_send_buf_size="150000" mcast_recv_buf_size="80000"
ucast_send_buf_size="150000" ucast_recv_buf_size="80000"
loopback="false" />
<PING timeout="2000" num_initial_members="3"
up_thread="true" down_thread="true" />
<MERGE2 min_interval="5000" max_interval="10000" />
<FD shun="true" up_thread="true" down_thread="true"
timeout="2500" max_tries="5" />
<VERIFY_SUSPECT timeout="3000" num_msgs="3"
up_thread="true" down_thread="true" />
<pbcast.NAKACK gc_lag="50" retransmit_timeout="300,600,1200,2400,4800"
up_thread="true" down_thread="true" />
<pbcast.STABLE desired_avg_gossip="20000"
up_thread="true" down_thread="true" />
<UNICAST timeout="5000" window_size="100" min_threshold="10"
down_thread="true" />
<FRAG frag_size="8192"
down_thread="true" up_thread="true" />
<pbcast.GMS join_timeout="5000" join_retry_timeout="2000"
shun="true" print_local_addr="true" />
<pbcast.STATE_TRANSFER up_thread="true" down_thread="true" />
Which properties map to the number of attempts to send a message and the timeout for
detecting another member is down? Any other parameters which look as if they need some
tweaking?
Thanks again.
