若要使基于域的命名空间在命名空间服务器之间保持一致,命名空间服务器需要定期轮询 Active Directory 域服务 (AD DS),以获取最新的命名空间数据。To maintain a consistent domain-based namespace across namespace servers, it is necessary for namespace servers to periodically poll Active Directory Domain Services (AD DS) to obtain the most current namespace data.

优化命名空间轮询的步骤To optimize namespace polling

按照以下过程优化命令空间轮询的执行方式:Use the following procedure to optimize how namespace polling occurs:

  1. 单击“开始”****、指向“管理工具”****,然后单击“DFS 管理”****。Click Start, point to Administrative Tools, and then click DFS Management.

  2. 在控制台树中的命名空间节点下,右键单击基于域的命名空间,然后单击属性In the console tree, under the Namespaces node, right-click a domain-based namespace, and then click Properties .

  3. 高级选项卡上,选择是否需要针对一致性或可伸缩性优化的命名空间。On the Advanced tab, select whether you want the namespace optimized for consistency or scalability.

    • 如果承载命名空间的命名空间服务器不超过 16 个,则选择针对一致性优化Choose Optimize for consistency if there are 16 or fewer namespace servers hosting the namespace.
    • 如果命名空间服务器超过 16 个,则选择优化可伸缩性Choose Optimize for scalability if there are more than 16 namespace servers. 这会减少主域控制器 (PDC) 模拟器上的负载,但会增加将对命名空间所做的更改复制到所有命名空间服务器所需的时间。This reduces the load on the Primary Domain Controller (PDC) Emulator, but increases the time required for changes to the namespace to replicate to all namespace servers. 在将更改复制到所有服务器之前,用户可能会得到该命名空间不一致的视图。Until changes replicate to all servers, users might have an inconsistent view of the namespace.

备注

若要使用 Windows PowerShell 设置命名空间轮询模式,请使用 Set-DfsnRoot EnableRootScalability cmdlet(在 Windows Server 2012 中引入)。To set the namespace polling mode by using Windows PowerShell, use the Set-DfsnRoot EnableRootScalability cmdlet, which was introduced in Windows Server 2012.
