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 deployment manager and the nodes as well as between the wsadmin scripting process and either the deployment manager or the application server. It uses the HTTP protocol to transfer files. When you enable security in the WebSphere® Application Server product, the file transfer service uses certificate-based mutual authentication. You can use the default key files in a test environment. Ensure that you change the default key file to secure your system.

The ports used for file transfer are the HTTP_Transport port, the HTTPS transport port, the administrative console port, and the administrative console secure port. [AIX Solaris HP-UX Linux Windows][IBM i]For more information, see the topic on port number settings in WebSphere Application Server versions. [z/OS]For more information, see the topic on default port assignments.

File synchronization service
The file synchronization service ensures that a file set on each node matches that on the deployment manager node. This service promotes consistent configuration data across a cell. You 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. You can configure the interval between operations or disable the periodic behavior. You can also configure the synchronization service to synchronize a node repository before starting a server on the node.

避免困難 避免困難:
  • 您必須使用管理主控台或 wsadmin Scripting 來同步化節點。在這兩個選項中,使用管理主控台是執行這項作業的最佳方法。管理主控台中的「節點」畫面包括同步化作業。

    如果您需要使用 wsadmin Scripting 來同步化節點,請使用 NodeSync MBean 的 sync() 指令。

  • 在同步化節點過程中,請勿重新啟動節點代理程式。透過節點代理程式起始並會影響應用程式伺服器的管理作業(例如,用於應用程式部署的節點同步化,或節點代理程式啟動時進行的更新),在節點代理程式有機會探索應用程式伺服器之前會失敗。
