Hi there,
I'm testing two JBoss 4.2.2 GA nodes in a cluster using the 'all' config. The
nodes cluster together fine. I then run a multithreaded client to start up 200
or so SFSBs that cycle through a number of states. The client requests are are
load balanced in the cluster as expected.
However, when I test failover by killing one of the nodes mid test, I get
various exceptions such as
javax.ejb.NoSuchEJBException, Could not find stateful bean:
4ss55r-gaev0q-f901ig99-1-f901ok6j-5w (bean was marked as removed)
and
javax.naming.NamingException, Could not dereference object
If I catch the exceptions and retry the client requests, then the SFSB state is
sorted out and the results are as they should be
I might have missed something here, but I was expecting the client side
interceptors to reroute client requests automatically on cluster member
failure, i.e. I shouldn't have to programmatically catch the exceptions and
retry.
I'm using HA-JNDI as follows
| jndiProps.put("java.naming.provider.url",
"jnp://foo.zub.com:1100,jnp://bar.zub.com:1100");
| jndiProps.put("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
| jndiProps.put("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
|
and I've added retry interceptors as per section 16.3.1.1 of the JBoss 4 manual.
Did I miss something? Or have I misunderstood how JBoss failover is dealt with
from the client?
Any insight/clarification gratefully received,
Regards,
Chris
