假設您有一個資料庫,其中包含 Microsoft SQL Server 2014 中的唯讀檔案組。 當您在資料庫上執行 DBCC CHECKDB 時, DBCC 命令無法建立資料庫的資料庫快照。如果沒有任何其他的資料庫連線,DBCC 操作就完成了且沒有錯誤。 不過,您會收到下列錯誤訊息:

DBCC CHECKDB 不會檢查 SQL Server 目錄或 Service Broker 一致性,因為無法建立資料庫快照或已指定了 TABLOCK。

如果有其他的資料庫連線,DBCC 操作會失敗,而且您會收到下列錯誤訊息:

Msg 5030、Level 16、State 12、Line 1The 資料庫無法以獨佔方式鎖定來執行該作業。Msg 7926、Level 16、State 1、Line 1Check 語句已中止。 無法檢查資料庫,因為無法建立資料庫快照,且無法鎖定資料庫或資料表。 如需此行為的詳細資料,以及存在哪些因應措施,請參閱線上叢書。 另請參閱先前的錯誤以取得詳細資料。



此問題最初是在 SQL Server 的後續累積更新中修正。

每個新的 SQL Server 累計更新都包含所有的修正程式,以及前一個累積更新中所包含的所有安全性修正程式。 我們建議您下載並安裝最新的 SQL Server 累積更新:


若要再現這個問題,請在 SQL Server 中執行下列命令:

-- Open a new query that is named conn1, and then create a new database. CREATE DATABASE DbTest GO -- Add a new file group. ALTER DATABASE DbTest ADD FILEGROUP FGTest GO -- Add a file to the new file group. ALTER DATABASE DbTest ADD FILE (NAME=DbTest_Data2, FILENAME=''C:\temp\DbTest_Data2.ndf') TO FILEGROUP FGTest GO -- Change the file group to read-only. ALTER DATABASE DbTest MODIFY FILEGROUP FGTest READONLY GO -- Run the DBCC CHECK command in the conn1 query. DBCC CHECKDB (DbTest) -- The DBCC CHECK command runs correctly. However, you may receive the following message: "DBCC CHECKDB will not check SQL Server catalog or Service Broker consistency because a database snapshot could not be created or because WITH TABLOCK was specified." -- Open a new query window that is named conn2, and then set the database as DbTest. This action opens a connection to the DbTest database. -- Return to the conn1 query, and run the DBCC command again. DBCC CHECKDB (DbTest) -- Notice the error message that is mentioned in the "Symptoms" section.
