适用场景

  • 全局文件缓存(GFC)核心
  • 全局文件缓存( GFC ) Edge

问题解答

问题: 如果有2个核心指向同一个数据共享、并且每个核心都有多个边缘。  什么可以防止从不同核心连接的两个用户在访问文件时发生冲突?

问题解答 : 不会发生冲突、因为GFC锁定发生在权威来源、而不是核心。锁定将位于Talon服务帐户下、可以查看后端文件服务器上的会话。

例如:

Core1和Core2都连接到后端A。假设我们使用的是MS Word、但不允许进行协作。

用户1 (Edge1)连接到核心1—打开file1.doc—文件在用户1的后端A上锁定

用户2 (Edge2)连接到Core2—尝试在后端A上打开同一个file1.doc。由于此文件已被用户1锁定、因此用户2将收到一条消息、指出此文件已锁定进行编辑。
