Hi Stacy,
I'm just about to post my code up here. So you can have a look at it, rip it
apart, whatever.
Looking forward to it :)

Yes, sorry, I got stuck thinking in two-node mode. I meant all. The

OK, in all those hours I have free as a student ;-) I have been thinking
about clustering, and this is what I've come up with.
Four parts of the EJB server need to become distributed for clustering to
work. By 'clustering
So this is the scenario where information could be shared in the JNDI tree

Hello,
This naming service would eventually need to be some sort of
federated/replicated thing, for HA. Each instance in the cluster
might run
its own NS.
that would be my recommendation too, just like weblogic where
each node runs
its own NS and content gets replicated across the
Yippee!! Or more precisely - clustering will make jBoss a 'real' commercial

Hello,
just some ideas to start a discussion...
As said in a precedent post, administration tools will be very important in
the clustering and they may also help, during the design phase, to see (as a
kind of "use cases") what features the clustering should provide.
I do not know much about
s of approach I want to think of SSB direct clustering :)

Hello,
My definition of application server clustering does not allow a
situation as
you just described Jeremy. The beans (actually the application) would be
deployed to the "cluster" and not to any particular node (or nodes) in a
cluster. On an implemenatation level, I would still expect

Hello,
ok, let me raise my voice :)
the emails around clustering seem to focus a lot on loadbalancing as the
primary reason to cluster servers.
well, imho it is not.
there is only one reason you would cluster servers, fail-over and high
availability.
"only one reason" is probably a bit
Maybe you are addressing Marc's concern about finding a small enough bite?
Clustering focused on fail-over first, then load-balancing?
I believe so, thanks for you humble respons, having a rough day, hope I
didn't bitch too much :)

if you want to do loadbalancing, you have much better performance using
non-clustered servers and a stateful loadbalancer.
as a matter of fact, you can buy a load balancing router for a couple of
thousand bucks, so why try to replicate functionality that is
already done.

Hmmm, game...
Would it be better to do it piecemeal like this, developing a bit at a
time, or to implement the underlying infrastructure first (like a
distributed transaction manager)?
