Hi,,
Recently i got up with IBM interview on Websphere Process server.
I faced question like
1.Diff b/w SCA.APPLICATION.widCell.Bus and SCA.SYSTEM.widCell.Bus
2.what is the use of activationSpecification while doing JMSBinding
can any one let me know about this.
Thank you very much for your support.

SCA system bus is used by SCA modules for their communications (e.g. when using SCA bindings, messaging destinations automatically generated within the SCA system bus scope. When you set up messaging for your own needs (e.g. your own queues or topics that you want to bind to using the JMS binding) then you should use the SCA application bus (or create another dedicated bus for that matter). Search the WebSphere Infocenter for more information on how to use and configure buses.
Activation specifications are used for inbound messaging scenarios (i.e. your application is triggered upon arrival of a message on a queue). You can imagine it as a kind of message event handler that monitors a queue for incoming messages. Its counterpart for outgoing messaging would be the connection factory.

"The SCA system bus is a service integration bus that is used to host queue destinations for Service Component Architecture (SCA) modules. The SCA run time, which supports mediation modules, uses queue destinations on the system bus as an infrastructure to support asynchronous interactions between components and modules.
The bus name is SCA.SYSTEM.busID.Bus. The authentication alias used for securing this bus is SCA_Auth_Alias"
&
"The application bus destinations support the asynchronous communication of WebSphere® Business Integration Adapters and other System Component Architecture components.
The bus name is SCA.APPLICATION.busID.Bus. The authentication alias used for securing this bus is SCA_Auth_Alias."
