All updates to the configuration files should go through the deployment manager.
2. What about IHS?

It serves the static content only and it takes up only http requests.
3. What about plug-in?
A. Plug-in is one of the modules it is interface between application server and web server,

load balancing, clustering, performance, highly availability, scalability, etc.
Exposes business logic to client applications through various protocols, possibly including HTTP.
Supports deployment of .war and .ear files Application server = web server + EJB container.
6. Diff b/w weblogic and websphere?
A. Both BEA Weblogic and IBM’s WebSphere provide J2EE based application servers which are competitors.
WebSphere leverages more on connectivity issues with MQ and legacy systems with strong dominance in J2EE.
