 ## Locking Behavior  
-Takes a shared lock on the DATABASE object. You cannot alter a database that is in use by another user for reading or writing. This includes sessions that have issued a [USE](http://msdn.microsoft.com/158ec56b-b822-410f-a7c4-1a196d4f0e15) statement on the database.

 ## Performance  
 Shrinking a database can take a large amount of time and system resources, depending on the size of the actual data within the database, and the amount of fragmentation on disk. For example, shrinking a database could take several hours or more.
