Remote files services for file transfer and file synchronization

Configuration documents describe the available application servers, their configurations, and their contents. Two file services manage configuration documents: the file transfer service and the file synchronization service.

The following information describes what the file services do:

File transfer service

The file transfer service enables the moving of files between the dmgr and the nodes as well as between the wsadmin scripting process and either the dmgr or the application server. It uses the HTTP protocol to transfer files. When you enable security in the WAS product, the file transfer service uses certificate-based mutual authentication. Use the default key files in a test environment. Ensure that you change the default key file to secure the system.

The ports used for file transfer are the HTTP_Transport port, the HTTPS transport port, the admin console port, and the admin console secure port.

See the topic on port number settings in WebSphere Application Server versions.

File synchronization service

The file synchronization service ensures that a file set on each node matches that on the dmgr node. This service promotes consistent configuration data across a cell. We can adjust several configuration settings to control file synchronization on individual nodes and throughout a system.

This service runs in the deployment manager and node agents, and ensures that configuration changes made to the cell repository are propagated to the appropriate node repositories. The cell repository is the master repository, and configuration changes made to node repositories are not propagated up to the cell. During a synchronization operation a node agent checks with the deployment manager to see if any configuration documents that apply to the node have been updated. New or updated documents are copied to the node repository, and deleted documents are removed from the node repository.

The default behavior, which is enabled, is for each node agent to periodically run a synchronization operation. Configure the interval between operations or disable the periodic behavior. We can also configure the synchronization service to synchronize a node repository before starting a server on the node.
