What is a node? Is it a machine or cpu?
Can I have more than one
managed servers on one node? what is node manager?
when was it introduced? What is the difference
between admin server and node manager?
Thanks.

Hi,
Node is neithere a CPU nor the machine. Its a Server Instance in the cluster (group of server instances providing the unified services as provided by the individual instances)

But I have seen one node manager handling
more than one managed servers on the same node.

Like Sameer said...
A node is a single instance of WebLogic Server. A single machine can have multiple instances of WebLogic (and therefore nodes) running currently.
A Node Manager is a Java program provided with WebLogic Server that enables you to start, shut down, restart, and monitor remote WebLogic Server instances. A Node Manager must be run on each physical machine running an instance of WebLogic Server that you would like to manage.
See this link: Managing Server Availability with Node Manager.
