Websphere Vertical Clustering

Hi,

I want to do a vertical clustering in WebSphere.

I have two nodes on same hardware server and the IP address is same. Were as the Unix login is different so has different ports i.e Boot strap and the default host port.

I have some configuration files which are used as shared library.

My doubt is which port number is to be used while deploying the applciation for boot strap in the provider url in the property file as the two servers are the nodes in the vertical cluster.

Please suggest.
