Hi all,
I'm having trouble with jboss messaging (JBoss AS 5.1 all profile) and a
graceful failover.
Given this:
Client sending messages to HA-JNDI port on a two-node cluster. When I kill -9
one of the nodes the client fails over perfectly, no messages are lost.
I'm using the jboss_init_redhat.sh script to handle startup and shutdown which
calls stop with:
JBOSS_CMD_STOP=${JBOSS_CMD_STOP:-"java -classpath $JBOSSCP org.jboss.Shutdown
-u myuser -p mypass --shutdown -s 127.0.0.1:2099"}
(i have hooked the jndi port into the jmx-consoles JAAS stuff AND changed it to
2099 as another app is running on the host).
Whenever i do a
service jboss5 stop
calling the above command the developer reports the client does not failover
but rather gets an exception:
12:37:39,681 DEBUG org.jboss.remoting.transport.socket.SocketClientInvoker -

We lose the messages. However, when the sending is done the client comes back
and uses the new node.
Failover appears to work fine as I can see it in the logs.
I DO have FailoverOnNodeLeave set to true.
So, what's the difference between a kill (or the ctrl-c'ing of run.sh, which is
a trapped kill) and the org.jboss.Shutdown method?
Can i adjust something on the server? or can the client change? i believe the
developers are using spring.
Thanks for any thoughts ...
August
