Hello - we're trying unsuccessfully to shrink the Master Temp DB file.  What's the trick to getting this down in size?  It's over 200GB on a 400GB partiition.  It's SQL 2008 on a Windows 2008 server.

Thanks

The best plan is to restart the SQL Server service when you have a window of inactivity.  If that is not an option here are suggestions from MSDN:

By the way I am assuming that you have already discovered why it increased in size and have corrected that process.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

Hi,

Do you have rowversioning turned on, or similar new features? Some of these new features do hammer the tempdb.

<You can use the sys.dm_db_file_space_usage dynamic management view to monitor the disk space used by the user objects, internal objects, and version stores in the tempdb files. Additionally, to monitor the page allocation or deallocation activity in tempdb at the session or task level, you can use the sys.dm_db_session_space_usage and sys.dm_db_task_space_usage dynamic management views. These views can be used to identify large queries, temporary tables, or table variables that are using a large amount of tempdb disk space.>

sorry for the delay, gentlemen - got sidetracked yesterday, and am getting back to this now.  I don't know what is causing it to grow, but will try and find out.  I have rebooted and restarted the service several times, with no change to the size, so there's something else going on.  Standby for more on this...

I've noticed the Initial Size parameter on the "tempdev.mdf" file is 207,000 MB.  Is this why restarting SQL isn't helping? it's simply resetting it back to that size?

yes, that will be the initial size of your tempdb file when the service starts

You need to use Method 1 from the link I posted in the first comment.

Don't forget to find out the cause, otherwise you may be back to where you started from here very soon.
