Cell

● A node is a logical grouping of serversEach node is managed by a

single node agent process

● A deployment manager process manages the node agentsHolds the configuration

repository for the entire management domain, called a cell

Administrative Console runs inside the DMgr


WebSphere

13

Managed vs. Unmanaged Nodes

● A managed node is a node that contains a node agent

Node agent acts as proxy for Deployment Manager

● An unmanaged node is defined in the topology, but does not have a node agent process

Useful for defining servers as part of the topology but outside of WebSphere’s management control

Lack of a node agent prohibits comprehensive management by WebSphere (except for the IBM HTTP Server v6.0)
