Ak používate Microsoft SQL Server 2000, musíte použiť SQL Server 2000 služby Pack 3a (SP3a), pred použitím skriptu, ktorý je popísaný v tomto článku.

Ďalšie informácie o možnostiach získania SQL Server 2000 Service Pack 3a, po kliknutí na nasledovné číslo článku databázy Microsoft Knowledge Base:

Tento článok je aktualizácia pre SQL Server 2000 alebo novšími verziami SQL Server nasledujúci článok databázy Microsoft Knowledge Base, ktorý sa uplatňuje na Microsoft SQL Server 7.0:
251004 Ako sledovať, SQL Server 7.0 blokovanie
Tento článok dokumentov na používanie a konštrukciu uloženej procedúry, ktoré môžete použiť na diagnostikovanie blokovanie a výkonnosti otázok. Popis ako pochopiť a vyriešiť, blokovanie, pozri nasledujúce článok v databáze Microsoft Knowledge Base:
224453 Pochopenie a riešenie SQL Server 7.0 alebo 2000 blokovanie problémy
V Microsoft SQL Server 2005, môžete tiež použiť Blokovaný proces správa Trieda udalostí v SQL Server Profiler zachytiť informácie o úlohu, ktorá bola zablokovaná dlhšie ako zadaný časový interval.

Ďalšie informácie o Blokovaný proces správa udalosť triedy nájdete na nasledujúcej webovej lokalite Microsoft Developer Network (MSDN):

DALSIE INFORMACIE

Nasledujúci popis sp_blocker_pss08 uložená procedúra zachytáva tejto informácie. Tieto informácie sa vzťahuje aj na SQL Server 2005.
  • Počiatočný čas (v závislosti na počítači, ktorý je spustenie služby SQL Server) tak, aby tento odber vzoriek blokovanie môže byť čas-zladené s Ďalšie informácie o výkone, ako je Microsoft Windows NT výkonnosť Monitorovať denníka alebo SQL Profiler denníka.
  • Informácie o pripojení na server SQL Server, zaslanie dotaze The sysprocesses systém tabuľky.
  • Informácie o zámok zdrojov, zaslanie dotaze syslockinfo systém tabuľky.
  • Informácie o prostriedkoch čaká spustením DBCC SQLPERF(WAITSTATS).
  • Aktuálne spustený SQL Server dávky pre pripojenia, ktoré iní sú blokované alebo blokovanie iného spustením DBCC INPUTBUFFER vyhlásenie.
  • Koncový čas podľa na počítač, na ktorom je spustený Server SQL Server.
Uložená procedúra bola vytvorená s týmito Optimalizácia znížiť vplyv na výkon a blokovanie spustením to uložená procedúra:
  • Neexistuje žiadny výstup generuje pokiaľ aspoň jeden spoj Čaká sa na prostriedku.
  • The sysprocesses a syslockinfo systém tabuľky z kapitán databáza sa vykoná dotaz priamo, zvýšiť výkon a Táto uložená procedúra zabrániť stáva blokované. Preto to, ktoré sa ukladajú postup je špecifický pre Microsoft SQL Server 2000 alebo novšími verziami programu SQL Server.
  • Malé worktable je vytvorený kurzor na získanie DBCC INPUTBUFFER výstup; mal by mať podstatný vplyv na používanie v tempdb databáza.
  • Pretože blokovanie môžete zmeniť počas zhromažďovania existuje rýchly režim informácie, ktoré zvyšuje výkon znížením výsledky príslušných riadkov sysprocesses a syslockinfo systémové tabuľky.
  • Ak sa snaží sledovať-lock zdrojov čaká, závora režim existuje, ktorý spôsobuje Zamknúť výstup vynechá.
Táto uložená procedúra je užitočná spustením z ľubovoľnej dotaz nástroj. Avšak, Microsoft navrhuje, postupujte podľa týchto krokov na vykonávanie blokujúca analýza:
  1. Vytvoriť uloženej procedúry sp_blocker_pss08, ktorá je na konci tohto článku, z ľubovoľnej dotaz nástroj, kým ste pripojení s prihlasovacie údaje, ktoré má sysadmin oprávnenia na serveri SQL Server alebo inštanciu servera SQL Server máte v pláne monitorovania.
  2. Vytvoriť súbor skriptu s nasledovný dotaz spustiť uložená procedúra v slučke. Všimnite si, že omeškanie by mala byť medzi 5 a 60
    sekúnd:

    ZATIAĽ ČO 1 = 1
    ZAČAŤ
    EXEC tempdb.dbo.sp_blocker_pss08
    --Alebo pre rýchly režim
    --EXEC. tempdb.dbo.sp_blocker_pss08 @ rýchlo = 1
    --Alebo režimu zámka
    --EXEC. tempdb.dbo.sp_blocker_pss08 @ závora = 1
    WAITFOR ODKLADU "00: 00:15"
    KONIEC
    ÍSŤ
  3. Táto produkcia je veľmi užitočné, keď sú kombinované s Microsoft Sledovanie výkonu systému Windows NT denník a denník SQL Profiler, tak aj na vytvorenie súčasne sa navrhuje. Informácie o ktoré Profiler a Výkon sledovanie udalostí na zachytenie, a informácie o tom, ako spNa interpretáciu výsledkov, pozri článok v Microsoft Knowledge Základne:
    224453Pochopenie a riešenie SQL Server 7.0 alebo 2000 blokovanie problémy
  4. Spustiť súbor skriptu, ktoré sa vytvorili v kroku 2 z Isql.exe, dotaz nástroja Osql.exe alebo pomôcky Sqlcmd v príkazovom riadku systému Windows na počítači so spustenou službou SQL Server, pre ktoré máte v úmysle monitorovať na zabránenie sieťových problémov odpojenie nástroja dotaz. Nasleduje príklad príkazového riadka, že môžete použiť na spustenie Osql.exe, ktoré predpokladá, že klient je spustený z počítača so spustenou službou SQL Server, a že je názov súboru skriptu Checkblk.sql. Skontrolujte, či správne parameter -S a sledovanie pomenovanú inštanciu nahraďte názvom servera SQL Server (alebo "servername\instance") "server". Tiež opraviť -i parameter a nahradiť "checkblk.sql" s cestu a názov súboru skriptu vytvorili v kroku 2.
    osql -E -Sserver -icheckblk.sql -ocheckblk.out -w2000
    Všimnite si, že musíte použiť iné prepínače príkazového riadka pre z nasledujúcich dôvodov:

    • Na zabránenie zalomenie riadka v produkcii súbory, ktoré uľahčuje čítanie.
    • Ak chcete odoslať výstup do súboru, určeného s -o parameter, namiesto na obrazovke tak, že ak dotaz nástroj má problémy, môžete stále mať výstup do dotazu nástroj zlyhá.
