I have shrink the large database. I have shrink the database log using SSMS and by query both way. on the properties it is showing the reduced size. But on the drive where it is mounted showing the previous size. What can I do to release the space after shrink of database?
After you shrink database and see the database size is reduced to release the unused empty space to file system, you can execute DBCC SHRINKDATABASE command with TRUNCATEONLY option once more

I've got a database on SQL Server 2008 R2 that has grown to 10GB (log file is tiny). Users cannot work because they get the message about not being able to allocate space, filegroup PRIMARY being full.
Database is in simple mode, the .mdf file is set to unlimited growth, the initial size says 10240MB and when I change it trough the manager it just goes back up.
Naturally shrinking trough Manager or T-SQL DBCC SHRINKFILE or SHRINKDATABASE does not work because of that (IIRC, shrink cannot go below minimal size).
What are my options now?
Create a new filegroup?
Why can't I reduce initial size?

I have a database table that is being used to store Xml. A lot of the records have a base64 pdf file within the Xml which is taking up a lot of space. If I clear the Xml column out the size of the database doesn't shrink. I've even tried completely deleting every record on our test database and the physical size of the database is still sitting at 300 GB. How do I get SQL to realize that the space is no longer being used and it should re-size?
I've tried DBCC Shrinkfile but it just makes the log file grow by 1GB.

To shrink a database
Using SQL Server Management Studio
In Object Explorer, connect to an instance of the SQL Server Database Engine, and then expand that instance.
Expand Databases, and then right-click the database that you want to shrink.
Point to Tasks, point to Shrink, and then click Database.
Database
Displays the name of the selected database.
Current allocated space
Displays the total used and unused space for the selected database.
Available free space
Displays the sum of free space in the log and data files of the selected database.
Reorganize files before releasing unused space
Selecting this option is equivalent to executing DBCC SHRINKDATABASE specifying a target percent option. Clearing this option is equivalent to executing DBCC SHRINKDATABASE with TRUNCATEONLY option. By default, this option is not selected when the dialog is opened. If this option is selected, the user must specify a target percent option.
Maximum free space in files after shrinking
Enter the maximum percentage of free space to be left in the database files after the database has been shrunk. Permissible values are between 0 and 99.
Click OK.
How to reduce log file size of MS SQL database. The requirement is to reduce log file of the version control server's DB, Shrinking is not an option in our case.
How to reduce log file size of MS SQL database
Shrinking is the only option here, but you need to clear out the log by backing it up first. Otherwise, there won't be any free space to shrink. After you shrink it once, you can keep it from getting blown out by either
Backing up your transaction logs more regularly. How often depends on your RPO
Setting the database to Simple Mode. This is only suggested if your RPO is large enough to where your FULL BACKUPs and DIFFERENTIALS would cover it.
I tried to shrink the log file but it only did small amount of free space.
The log space of tempdb is full due to the data file.
How can I free the space?
Edit:
I have checked following:
1. Bad queries are running - NO Queries are running
DBCC OPENTRAN - No Result
The tempdb is in SIMPLE recovery mode.
I have a separate drive for Transaction log of 1TB i.e. 40% free now.
Observation:
When I Right click on tempdb>task>shrink>database shows 99% free space available. Can I shrink the database file here?
Restarting the SQL instance will flush the tempdb and recreate it.
First of all, I know it's better not shrink database. But in our situation we had to shrink the data file to claim more space back.
Environment: SQL Server 2005 x64 SP3 Ent running on Windows Server 2003 Enterprise x64.
The database has one single data file and one log file. Before we run DBCC SHRINKFILE, the data file has 640GB, in which 400GB is free, so the data is about 240GB. To speed up the shrink process,we had to defrag the database first then we shrink data file.
However, after we shrinked the database data file using DBCC SHRINKFILE, the data changed to 490GB. How could it happen?
I asked around include Paul Randal. Here's the possible reason:
When I rebuild indexes for those indexes that were dropped, the indexes would not physically removed from data file, they would be put in deferred drop queue, instead they would stay there and would be dropped in batch.
