Check Database Integrity Task (Maintenance Plan)

  • Článek

Applies to: SQL Server

Use the Check Database Integrity Task dialog to check the allocation and structural integrity of user and system tables, and indexes in the database, by running the DBCC CHECKDB Transact-SQL statement. Running DBCC CHECKDB ensures that any integrity problems with the database are reported, thereby allowing them to be addressed later by a system administrator or database owner.

Options

  • Connection

    Select the server connection to use when performing this task.

  • New

    Create a new server connection to use when performing this task. The New Connection dialog box is described below.

  • Databases

    Specify the databases affected by this task.

    • All databases

      Generate a maintenance plan that runs maintenance tasks against all Microsoft SQL Server databases except tempdb.

    • All system databases

      Generate a maintenance plan that runs maintenance tasks against each of the SQL Server system databases except tempdb. No maintenance tasks are run against user-created databases.

    • All user databases

      Generate a maintenance plan that runs maintenance tasks against all user-created databases. No maintenance tasks are run against the SQL Server system databases.

    • These specific databases

      Generate a maintenance plan that runs maintenance tasks against only those databases that are selected. At least one database in the list must be selected if this option is chosen.

      Note

      Maintenance plans only run against databases set to compatibility level 80 or higher. Databases set to compatibility level 70 or lower are not displayed.

  • Include indexes

    Check the integrity of all the index pages and table data pages.

  • Physical only

    Limits the check to the integrity of the physical structure of the page, record headers, and the allocation consistency of the database. Using this option may reduce run-time for DBCC CHECKDB on large databases, and is recommended for frequent use on production systems.

  • Tablock

    Causes DBCC CHECKDB to obtain locks instead of using an internal database snapshot. This includes a short-term exclusive (X) lock on the database. Using this option may help DBCC CHECKDB run faster on a database under heavy load, but decreases the concurrency available on the database while DBCC CHECKDB is running.

  • View T-SQL

    View the Transact-SQL statements performed against the server for this task, based on the selected options.

    Note

    When the number of objects affected is large, this display can take a considerable amount of time.

New Connection dialog box

  • Connection name

    Enter a name for the new connection.

  • Select or enter a server name

    Select a server to connect to when performing this task.

  • Refresh

  • Use Windows integrated security

  • Use a specific user name and password
