Subject Clients failover in HA mode
Date Fri, 27 Jun 2008 04:52:05 GMT

Currently i implemented a HA system with two servers and each client is
connected to one server.

when one server die, and the producer and consumer client connecting to it
failover to the other live server. During this period, there is constant
large stream of messages being send. 

i tag each message with a Number ID. i notice that some message is lost.. To
my understanding, the connection is TCP/IP. 

i did a script to make the client fallback quickly to server after it went
back online again. the old "lost" messages then are send to the client. i
believe the network bridge is not yet established when i fall back the

but not all the messages are accounted..

Can anyone shed some light on this two matter. =)
