A group of related nodes and their node agents constitute a cell. Administrators define the nodes that make up a cell according to criteria that is appropriate in their environment.
A cell contains a Deployment Manager from which all the administrative tasks for the nodes in that cell are handled. Deployment Manager for the cell has a master configuration repository that contains the configuration data for the nodes and servers within the cell. Configuration changes made at the cell level are propagated to the nodes and servers the next time synchronization occurs. Therefore, all configuration changes must be made at the cell level.
Although each node and server in a cell have their own local configuration files, configuration changes made at the node or server level are temporary and will be overlaid with the data from the cell repository maintained by the Deployment Manager.
