Shrink Database Task

Shrink Database Task

The Shrink Database task reduces the size of SQL Server database data and log files.

By using the Shrink Database task, a package can shrink files for a single database or multiple databases.

Shrinking data files recovers space by moving pages of data from the end of the file to unoccupied space closer to the front of the file. When enough free space is created at the end of the file, data pages at end of the file can deallocated and returned to the file system.

Caution note Caution

Data that is moved to shrink a file can be scattered to any available location in the file. This causes index fragmentation and can slow the performance of queries that search a range of the index. To eliminate the fragmentation, consider rebuilding the indexes on the file after shrinking.

The Shrink Database task encapsulates a DBCC SHRINKDATABASE command, including the following arguments and options:

  • database_name

  • target_percent


If the Shrink Database task shrinks multiple databases, the task runs multiple SHRINKDATABASE commands, one for each database. All instances of the SHRINKDATABASE command use the same argument values, except for the database_name argument. For more information, see DBCC SHRINKDATABASE (Transact-SQL).

You can set properties through the SSIS Designer. This task is in the Maintenance Plan Tasks section of the Toolbox in SSIS Designer.
