在Hyper-V中运行SQL Server时“等待操作超时”

Modified on: Thu, 10 Oct 2019 00:40:02 +0800

我在Hyper-V实例上运行SQL Server(2012)。它拥有充足的资源和25%的总资源,VHD放置在速度非常快的SSD驱动器上,以便快速响应。

当有一段时间没有访问使用SQL Server的应用程序时,他们会收到错误“等待操作超时”。当重新加载或重试访问数据库时,它似乎已经“醒来”并且一如既往地快速。

有没有办法确保在这种环境下不会出现这种软睡眠模式?

异常详细信息: System.ComponentModel.Win32Exception:等待操作超时

最佳答案

尝试执行此命令:

  

exec sp_updatestats

令人难以置信的是,它解决了这个问题。

执行命令之前的错误代码。
