Profile : It provides you a run-time environment. We have 4 different types of profiles in WAS 6.1 ND, based on your application/project environment we will select/create the profile.
For Ex:
* you want to create a standalone environment just create Application Server Profile.
* you want to create distributed/clustering environment, we have to create
Application Server and Dmgr profile. Later we have to federate Application server
to DMGR. (or) Simply create a Cell profile(which is a combination of DMGR and
federated AppServer).
Node : Whenever you create any profile(Cell/DMGR/AppServer/Custom), we will get a node. The main purpose of the node is to administer the AppServer's created under the node. The main point to be noted here is : In DMGR profile, this node will not be directly highlighted instead a CellManager will replace its place.
NodeAgent : The main advantage of NodeAgent is for Synchronising. This comes into picture when you federate a node to DMGR. There is no command/option in WAS to start/stop Nodeagent. If you start/stop node, automatically nodeagent will be also start/stop.
If the node/nodeagent was down, there will be no impact to running app's. The only impact is you cant start the stopped AppServer's under that node untill the node was started.
Without creating any profile, we wont get NODE into the picture.
