更多信息
對 sp_blocker_pss80 存儲(chǔ)過程的下列描述可捕獲此信息： • 開始時(shí)間（視運(yùn)行 SQL Server 的計(jì)算機(jī)而定），以便此阻塞采樣在時(shí)間上可以與其他性能信息（如 Windows NT 性能監(jiān)視器日志或 SQL 事件探查器日志）一致。
• 有關(guān)與 SQL Server 的連接的信息，通過查詢 sysprocesses 系統(tǒng)表獲取。
• 有關(guān)鎖定資源的信息，通過查詢 syslockinfo 系統(tǒng)表獲取。
• 有關(guān)資源等待的信息，通過運(yùn)行 DBCC SQLPERF(WAITSTATS) 獲取。
• 用于連接（被其他連接阻塞或者阻塞其他連接）的當(dāng)前正在運(yùn)行的 SQL Server 批處理，通過運(yùn)行 DBCC INPUTBUFFER 語句獲取。
• 結(jié)束時(shí)間，視運(yùn)行 SQL Server 的計(jì)算機(jī)而定。
創(chuàng)建該存儲(chǔ)過程時(shí)使用了下列優(yōu)化，從而降低了運(yùn)行該存儲(chǔ)過程對性能和阻塞的影響： • 除非至少有一個(gè)連接在等待資源，否則不生成輸出。
• 直接查詢 master 數(shù)據(jù)庫中的 sysprocesses 和 syslockinfo 系統(tǒng)表，以提高性能并防止該存儲(chǔ)過程被阻塞。因此，該存儲(chǔ)過程是特定于 Microsoft SQL Server 2000 的。
• 使用光標(biāo)創(chuàng)建一個(gè)小工作表來獲取 DBCC INPUTBUFFER 輸出，這對在 tempdb 數(shù)據(jù)庫中的使用應(yīng)沒有太大影響。
• 由于收集信息時(shí)阻塞可以更改，因此存在一種快速模式，該模式可將所得到的結(jié)果降至 sysprocesses 和 syslockinfo 系統(tǒng)表的相關(guān)行，從而提高了性能。
• 如果您試圖跟蹤非鎖定資源等待，則存在一種鎖存模式，該模式可導(dǎo)致鎖定輸出被忽略。
該存儲(chǔ)過程從任何查詢工具運(yùn)行，都十分有用。但是，Microsoft 建議您按照下列步驟來執(zhí)行阻塞分析： 1. 當(dāng)使用對計(jì)劃要監(jiān)視的 SQL Server 服務(wù)器或 SQL Server 實(shí)例具有 sysadmin 特權(quán)的登錄信息進(jìn)行連接時(shí)，從任何查詢工具創(chuàng)建存儲(chǔ)過程 sp_blocker_pss80（在本文末尾提供）。
2. 創(chuàng)建一個(gè)包含以下查詢的腳本文件以循環(huán)運(yùn)行該存儲(chǔ)過程。請注意，延遲應(yīng)在 5 秒和 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. 該輸出在與 Microsoft Windows NT 性能監(jiān)視器日志和 SQL 事件探查器日志結(jié)合時(shí)非常有用，因此建議同時(shí)創(chuàng)建這兩種日志。有關(guān)要捕獲哪些事件探查器和性能監(jiān)視器事件的信息，以及有關(guān)如何解釋結(jié)果的信息，請參閱下面的 Microsoft 知識庫文章：
224453 (http://support.microsoft.com/kb/224453/) 了解和解決 SQL Server 7.0 或 2000 阻塞問題
4. 在運(yùn)行 SQL Server 的計(jì)算機(jī)（您要對其進(jìn)行監(jiān)視以防止網(wǎng)絡(luò)問題導(dǎo)致查詢工具斷開連接）上，在 Windows 命令提示符處從 Isql.exe 或 Osql.exe 查詢工具運(yùn)行在第 2 步創(chuàng)建的腳本文件。下面是可用于啟動(dòng) Osql.exe 的示例命令行，它假定客戶端從運(yùn)行 SQL Server 的計(jì)算機(jī)運(yùn)行，并且腳本文件名為 Checkblk.sql。請務(wù)必更正 -S 參數(shù)，并將“server”替換為 SQL Server 服務(wù)器的名稱（或“servername\instance”，如果您監(jiān)視的是已命名實(shí)例）。此外，還必須更正 -i 參數(shù)，并將“checkblk.sql”替換為在第 2 步中創(chuàng)建的腳本文件的路徑和名稱。 osql -E -Sserver -icheckblk.sql -ocheckblk.out -w2000
請注意，由于下列原因，您必須使用其他命令行開關(guān)：
• 為了防止輸出文件中出現(xiàn)換行（換行可使輸出文件更易于閱讀）。
• 為了將輸出發(fā)送到使用 -o 參數(shù)指定的文件，而不是發(fā)送到屏幕，以便在查詢工具出現(xiàn)問題時(shí)，在查詢工具失敗之前仍得到輸出。
