[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Re: Shared Transport in JGroups

[clebert.suconic@jboss.com]

We plan to use JGroups 2.6.2 on Branch_Stable.

JBossMessaging currently requires an application server... 
The only standalone ATM is our testsuite.


This is the UDP stack we have successfully tested:

         <config>
  |             <UDP
  |                  mcast_addr="${jboss.messaging.controlchanneludpaddress,jboss.partition.udpGroup:228.7.7.7}"
  |                  mcast_port="${jboss.messaging.controlchanneludpport:45568}"
  |                  tos="8"

  |                  ucast_send_buf_size="640000"

  |                    retransmit_timeout="50,300,600,1200"

  |             <pbcast.FLUSH timeout="20000"/>
  |         </config>
  |  

And this is our TCP stack:

         <config>
  |             <TCP start_port="7900"

We really need UNICAST on tcp, and pbcast.STATE_TRANSAFER and pbcast.FLUSH. As far as I remember these items are not described on the MUX channel at JBoss5.
