NHibernate: Freeing .mdf file

Question

I'm using NHibernate for a project. This project opens a SQL Server 2005 database and then, after all work is done, It's supposed to backup the database. The problem is that SQL Server keeps the handle open after calling factory.Close(), so the backup copy fails. How do I close the file handle? Thanks in advance.

Answer 1

If you are trying to make a copy of the database file you can take the database offline.

ALTER DATABASE AdventureWorks SET OFFLINE

--Copy the data file

ALTER DATABASE AdventureWorks SET ONLINE

To take an online backup you can use the BACKUP DATABASE command.

BACKUP DATABASE AdventureWorks 
 TO DISK = 'Z:\SQLServerBackups\AdvWorksData.bak'
