Weird clustererror

[metalhead]

Hello, I'm experiencing some weird errors... my guess is it has something to do with clustering... (using JBoss 4.0.3)

We're developping in a small team, in one chamber, using the same switch.

Now, when my colleague starts jboss first, and after that I start JBoss, my Application fails.

This is part of the console of my colleague (ELECTRA);

And this is my console (HYPERION):

08:23:13,015 WARN [FD] ping_dest is null: members=[ELECTRA:1321, 172.16.3.77:1234], pingable_mbrs=[172.16.3.77:1234], local_addr=172.16.3.77:1234

Is this problem cluster-related? And if so, how can I fix this?

[azhurakousky]

Without getting into to many details here is a quck explanation and a fix:

Being on the same network you are attempting to Join the cluster (weather you like it or not). You can clearly see that two JGroups stacks are talking and shunning mambers since they belong to a different grous.

Start your JBoss as follows:

run -c <conf_name> -g ELECTRA_PARTITION -u 230.1.2.10
run -c <conf_name> -g HYPERION_PARTITION -u 230.1.2.11

Opotion -g will create a unique name for a cluster partition, so you won't have a conflict such as DefaultPartition.
Option -u will override a default Multicast address.

With that, your servers will not even see each other.

On the oposute side if you do want two of them join the cluster thenmake suer that values of -g and -u are the same on bothe machines
