Cells are logical groupings of one or more nodes in a WAS distributed network. Clusters are contained within cells. One cell can contain multiple clusters.
A cell retains master XML configuration files for each server in every node in the cell, with each node and server also having their own local XML configuration files.
Changes to a local node or to a server configuration file are temporary, and will be overwritten during synchronization, if the node or server belongs to a cell. Changes to server and node configuration files at the cell level are permanent.
Synchronization occurs when a server starts, or when a syncNode.sh is executed.
