[Installation, Configuration & Deployment] - Re: JBOSS CLUSTERING ON VIRTUAL MACHINE (LINUX)

Bump......
I have tried all of the following and I'm thorougly stumped. Any help would be appreciated.
1. Make sure that I have multicast working. I followed the instructions here
http://kbase.redhat.com/faq/FAQ_45_4865.shtm
using "ping 224.0.0.1" I receive the following.
| 64 bytes from 192.168.109.11: icmp_seq=0 ttl=64 time=0.966 ms
| 64 bytes from 192.168.109.10: icmp_seq=0 ttl=64 time=4.78 ms (DUP!)
| 64 bytes from 192.168.109.11: icmp_seq=1 ttl=64 time=1.45 ms
| 64 bytes from 192.168.109.10: icmp_seq=1 ttl=64 time=0.882 ms (DUP!)
|
I have the following from "iptables --list"
| iptables --list
| Chain INPUT (policy ACCEPT)
| target prot opt source destination
|
| Chain FORWARD (policy ACCEPT)
| target prot opt source destination
|
| Chain OUTPUT (policy ACCEPT)
| target prot opt source destination
|
So at my network level I should be good. I don't have any firewall, and multicast is enabled. I then created the following text.xml and placed it on both node 1 and node 2.
| <Config>
| <UDP mcast_addr="228.1.2.3" mcast_port="45566"
| ip_ttl="8" ip_mcast="false"
| mcast_recv_buf_size="2000000" mcast_send_buf_size="640000"
| ucast_recv_buf_size="2000000" ucast_send_buf_size="640000"
| loopback="true"
| />
| <PING timeout="2000" num_initial_members="3"
| up_thread="true" down_thread="true"/>
| <MERGE2 min_interval="10000" max_interval="20000"/>
| <FD_SOCK down_thread="false" up_thread="false"/>
| <FD shun="true" up_thread="true" down_thread="true"
| timeout="10000" 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"
| max_xmit_size="8192"
| up_thread="true" down_thread="true"/>
| <UNICAST timeout="300,600,1200,2400,4800" window_size="100" min_threshold="10"
| down_thread="true"/>
| <pbcast.STABLE desired_avg_gossip="20000" max_bytes="400000"
| up_thread="true" 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"/>
| </Config>
|
I then start each node with the following command
| java -Djava.net.preferIPv4Stack=true -cp lib/concurrent.jar:server/all/lib/jgroups.jar:server/all/lib/commons-logging.jar org.jgroups.demos.ViewD
| emo -props test.xml
|
I get the following output for node 1
| Apr 23, 2007 11:31:12 AM org.jgroups.protocols.UDP createSockets
| INFO: unicast sockets will use interface 192.168.109.10

This is node 2

I'm utterly stumped. I've followed all of the diagnostics I can think of, and I still am not having any luck connecting. The diagnostics tell me that the systems aren't communicating, but they don't tell me a starting point to work with. I've tried to telnet to the port that it says its listening on, but I can't connect to the socket. Can anyone give me a hand?
Thanks,
Todd

hi Oskar,
My Problem is That it (some other program) send me messages and wait to answer (of course i have synchronus responses )
yes i know about ques but i can't use it :(
first i must return value and second multiple database persist in one transaction (i think you understand multiple database insert in one transaction - i have transaction marker and i want to persist both database insert with this markers)
Regards,
Paata
