Configuration repositories
A configuration repository stores configuration data. By default, configuration repositories reside in the config subdirectory of the product installation root directory.
A cell-level repository stores configuration data for the entire cell and is managed by a file repository service that runs in the deployment manager. The deployment manager and each node have their own repositories. A node-level repository stores configuration data needed by processes on that node and is accessed by the node agent and application servers on that node.
When you change a WebSphere Application Server configuration by creating an application server, installing an application, changing a variable definition or the like, and then save the changes, the cell-level repository is updated. The file synchronization service distributes the changes to the appropriate nodes.
