What are nodes in a cluster?

[saswata]

Hi ,

     I would like to know , the concept of Nodes in a JBoss Cluster environment.

Is a node , a single physical machine with its own IP Address, and a Jboss Server Instance running ?

Can we have multiple Jboss Instances in a single Node?

Thanks & Regards

Ok ,

I found out :-

That a node is an JBoss Application Server instance.

So , we can have multiple JBoss Application Server instances in a single machine. That way we shall have multiple nodes in a single machine.

Each node will have the same IP Address ( ie. the macines IP Address), but a different port number.

So , how can we provide different ports for each instance of JBoss Application Server ??

Eagerly waiting for a reply.

Thanks & Regards

This is achieved using the service binding manager, which allows you to assign a set of ports to a server.

./bin/run.sh -Djboss.service.binding.set=ports-default all

./bin/run.sh -Djboss.service.binding.set=ports-01 all

"ports-default" will use the default set of ports.  "ports-01" will add 100 to the default set of ports.

Hi Paul,

    I am using JBoss AS 4.2.0 GA on a Windows Platform.

How can I enable the Service Binding Manager for JBoss ?

If I mention , -Djboss.service.binding.set=ports-01 all in run.bat , "ports-01" will add 100 to the default set of ports.

But, how shall I , assign , different port values for the different JBoss Application Server Instances ??

Thanks & Regards
