結論

本文是下列「Microsoft 知識庫」文件對於 Microsoft SQL Server 2000 (含) 以後版本之 SQL Server 的更新,適用於 Microsoft SQL Server 7.0:
251004  (http://support.microsoft.com/kb/251004/ ) INF:如何監視 SQL Server 7.0 封鎖
本文說明您可以用於診斷封鎖及效能問題之預存程序的用法與設計。如需有關如何了解與解決封鎖的說明,請參閱下列「Microsoft 知識庫」中的文件:
224453  (http://support.microsoft.com/kb/224453/ ) INF:瞭解並解決 SQL Server 7.0 封鎖問題
在 Microsoft SQL Server 2005 中,您也可以使用 SQL Server Profiler 中的封鎖處理程序報告事件類別,擷取封鎖時間較指定時間還長之工作的相關資訊。

如需有關封鎖處理程序報告事件類別的詳細資訊,請造訪下列 Microsoft Developer Network (MSDN) 網站:
http://msdn2.microsoft.com/zh-tw/library/ms191168.aspx (http://msdn2.microsoft.com/zh-tw/library/ms191168.aspx)

其他相關資訊

下列 sp_blocker_pss80 預存程序說明會使用此資訊。此資訊亦適用於 SQL Server 2005。
  • 啟動時間 (視執行 SQL Server 的電腦而定),如此封鎖取樣的時間即可與其他效能資訊 (如 Microsoft Windows NT 效能監視器記錄或 SQL Profiler 記錄) 的時間一致。
  • 連線至 SQL Server 的相關資訊 (藉由查詢 sysprocesses 系統表格)。
  • 鎖定資源的相關資訊 (藉由查詢 syslockinfo 系統表格)。
  • 資源等待的相關資訊 (藉由執行 DBCC SQLPERF(WAITSTATS))。
  • 目前針對其他項目所封鎖或封鎖其他項目之連線 (藉由執行 DBCC INPUTBUFFER 陳述式) 而執行的 SQL Server Batch。
  • 結束時間 (視執行 SQL Server 的電腦而定)
預存程序會以下列最佳化方式建立,藉此減少執行此預存程序對效能及封鎖的影響:
  • 至少有一條連線正在等待資源,否則不會產生任何輸出。
  • master 資料庫的 sysprocesses 竹與 syslockinfo 系統表格會以直接方式查詢,藉此提高效能,並防止此預存程序遭到封鎖。因此,此預存程序是 Microsoft SQL Server 2000 (含) 以後版本之 SQL Server 特有的項目。
  • 由游標建立小型工作表格,藉此取得 DBCC INPUTBUFFER 輸出;這對 tempdb 資料庫的使用狀況應不會造成重大的影響。
  • 由於封鎖在搜集資訊期間可能會有所變更,因而提供了快速模式,以降低 sysprocessessyslockinfo 系統表格相關列之結果數的方式提高效能。
  • 如果是嘗試追蹤非鎖定資源等待數,便會提供閂鎖模式而可略過鎖定輸出。
此預存程式如果是透過查詢工具加以執行,則此預存程序非常有用。但 Microsoft 建議您依照下列步驟執行封鎖分析:
  1. 透過查詢工具建立本文結尾所提供的預存程序 sp_blocker_pss80,並以具有 SQL Server 伺服器或所要監視之 SQL Server 執行個體的 sysadmin 權限登入連線。
  2. 使用下列查詢建立指令碼檔案,以迴圈方式執行此預存程序。請注意,延遲應介於 5 至 60 秒之間:
    WHILE 1=1
    BEGIN
       EXEC master.dbo.sp_blocker_pss80
       -- Or for fast mode 
       -- EXEC master.dbo.sp_blocker_pss80 @fast=1
       -- Or for latch mode 
       -- EXEC master.dbo.sp_blocker_pss80 @latch=1
       WAITFOR DELAY '00:00:15'
    END
    GO
  3. 此輸出在與 Microsoft Windows NT 效能監視器記錄及 SQL Profiler 記錄合併使用時非常有用,因此建議您同時建立兩者。如需有關所要擷取之 Profiler 與效能監視器事件,以及如何解譯結果的資訊,請參閱下列「Microsoft 知識庫」中的文件:
    224453  (http://support.microsoft.com/kb/224453/ ) INF:瞭解並解決 SQL Server 7.0 封鎖問題
  4. 在執行 SQL Server 之電腦的 Windows 命令提示字元中,利用 Isql.exe、Osql.exe 查詢工具或 Sqlcmd 公用程式,執行步驟 2 中所建立的指令碼檔案;而此 SQL Server 電腦即是所要監視,以避免網路問題造成查詢工具中斷的對象。以下是可以用於啟動 Osql.exe 的範例命令列,其假設用戶端是從執行 SQL Server 的電腦上執行,且指令碼檔案的名稱為 Checkblk.sql。請更正 -S 參數,並將 "server" 取代為 SQL Server 伺服器的名稱 (如果是監視具名執行個體,則為 "servername\instance")。同時也請更正 -i 參數,並將 "checkblk.sql" 取代為步驟 2 所建立之指令碼檔案的路徑與名稱。
    osql -E -Sserver -icheckblk.sql -ocheckblk.out -w2000
    請注意,基於下列理由,您還須使用其他命令列參數:

    • 避免輸出檔案因閱讀方便而換行。
    • 如果要將輸出傳送至檔案,而不是傳送至螢幕,請指定 -o 參數;只要查詢工具不失敗而僅是發生問題,您仍可擁有輸出。
下列指令碼可建立 sp_blocker_pss80 預存程序:
