Domanda

Sto tentando di individuare una situazione di stallo che si sta verificando nel nostro database SQL 2005 (64 bit).Al momento non abbiamo abilitato l'isolamento degli snapshot.

Ho acceso TF-1204 e ho ricevuto l'output di seguito.

Da questo output sono in grado di determinare che il Nodo 1 è una procedura memorizzata che seleziona i dati e modifica solo i valori nelle tabelle #temp.

Il nodo 2 è un'altra procedura memorizzata che esegue un semplice aggiornamento basato sulla chiave primaria su una singola riga di dati.

Ciò che non riesco a determinare è la risorsa effettiva che era in conflitto qui.Le chiavi di 10:72057594060734464 e 10:72057594038910976 mi consentono di determinare il database, ma questi ID oggetto non possono essere risolti con object_name.In effetti, dovrebbero essere valori int, quindi non sono sicuro da dove provengano questi numeri grandi.

Nella ricerca del problema sono riuscito a ottenere valori simili anche da Activity Monitor per Object ID.

Come risolvo questi identificatori di oggetto?

Ecco l'output del deadlock tf-1204:

Soluzione

Questi ID in realtà si riferiscono agli hobt (Heap o Binary Tree), che si trovano in sys.partitions.Prova la seguente query all'interno del database 10 e scoprirai quale oggetto e quale indice sono interessati.

SELECT hobt_id, object_name(p.[object_id]), index_id 
FROM sys.partitions p 
WHERE hobt_id = 72057594060734464
