Strange behaivour of jboss cluster

[gdevito]

Hi all,
I have two Host (A,B).
Each host has a multihomed Jboss installation.
Server A : Address ipA1, Address IpA2
Server B : Address ipB1, Address IpB2

Server A : Jboss1, Jboss2
Server B : Jboss1, Jboss2

Each Jboss1 is in the same cluster.
Jboss2 are another cluster.

My jboss version is 3.2.2.

Jboss1 contains a j2ee application and hosts some ejbs (Stateless EJB)
Jboss2 contains only ejbs (Stateless EJB).

In a JSP page I do two lookups : one for an EJB hosted by Jboss1 and
one for an EJB hosted by Jboss2. Jndi query are cached.


If I stop Jboss2, sometimes I get Service unavalible in the stack trace.
But this happends only for ejbs of Jboss2.
My jndi lookup looks like this :
p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL,"ipA1:1101,ipA2:1101");
p.put("jnp.partitionName","myPartition");
p.put("jnp.discoveryGroup","224.10.10.10");
p.put("jnp.discoveryPort","1103");


Moreover, Jboss1 and Jboss2 have different Partition and Multicast
address. Each Jboss is started with --host option.


Anyone can help me ?

For clarification: what exactly is meant by "multi-homed" ?
I have seen thisterm in other dicsussion?

Is it "Two different Nodes whose cluster-service.xml references the same Partition" ?

[gdevito]

Multihomed means that :

Each ServerA and ServerB has two jboss instances with different Ip address binded.

Ex.:
Server A ==> two Ip Alias : 192.168.10.186, 192.168.10.188
First Jboss Instance
192.168.10.186 jboss.bind.address

Second Jboss Instance
192.168.10.188 jboss.bind.address


Server B ==> two Ip Alias : 192.168.10.187, 192.168.10.189
First Jboss instance
192.168.10.187 jboss.bind.address

Second Jboss instance
192.168.10.189 jboss.bind.address


Each First JBoss instance of ServerA and Server B forms a Cluster
in the DefaultPartition with the same multicast ip address and
group (HAJndi 1100).

Each Second Jboss instance of Server A and Server B forms another
Cluster in MyPArtition with the same multicast ip address and group
but different from the first Jboss instance
HAJNdi 1101

BEST regards.
