2.3.3 File synchronization

The file synchronization service is the administrative service responsible for keeping up to date the configuration and application data files that are distributed across the cell. The service runs in the deployment manager and node agents, and ensures that changes made to the master repository will be propagated out to the nodes, as necessary. The file transfer system application is used for the synchronization process. File synchronization can be forced from an administration client, or can be scheduled to happen automatically.

During the synchronization operation, the node agent checks with the deployment manager to see if any files that apply to the node have been updated in the master repository. New or updated files are sent to the node, while any deleted files are also deleted from the node.

Synchronization is one-way. The changes are sent from the deployment manager to the node agent. No changes are sent from the node agent back to the deployment manager.
