Sql-Server
在 Hyper-V 中執行 SQL Server 時出現“等待操作超時”
我在 Hyper-V 實例上執行 SQL Server (2012)。它擁有充足的資源和總資源的 25% 預留,VHD 放置在非常快的 SSD 驅動器上,以實現快速響應時間。
有時,當使用 SQL Server 的應用程序有一段時間沒有被訪問時,它們會收到錯誤“等待操作超時”。當重新載入或重試訪問數據庫時,它似乎已經“喚醒”並且和以往一樣快。
有什麼辦法可以保證這種環境下不會出現這種軟睡眠模式?

異常詳細資訊: System.ComponentModel.Win32Exception:等待操作超時
嘗試執行此命令:
執行 sp_updatestats
令人難以置信的是,它解決了這個問題。
上面的程式碼是命令執行之前的錯誤。
