Help For Shrinking Database
Jun 20, 2006
Hi guys.
I have a huge database file. When I run sp_spaceused this are the
results:
db_size 1337,31 Mb
unallocated 14,62 Mb
reserved 1088456 Kb
data 258992 Kb
index_size 6224 Kb
unused 823240 Kb
Now, when I run dbcc shrinkfile(database_name, 50) or whatever value of
percent, it says there is not enough free space in db.
Please advice how to shrink the size of that file and why is it so big?
Thanks in advance

Hi All,
I am working on a client product that shrinks the database in MS SqlServer. After shrinking the database files, it does not send any email notification to the users.
My question is: Is there any way in SqlServer to sense that the database has been shrunk and send a notification to the users (may be through an Alert or a Job or something). Please let me know the steps to do that.
Thanks
Sri

I have a SQL 2000 database that I would like to shrink.
Recovery Model = Simple
Data file space allocated = 78 Gig
Space free = 41 Gig
Similar problems with Trans logs sometimes
As I understand it, I can't shrink the database below the allocated size. How do I get that space back ?
Any extra insights and explanations about this topic in general would be appreciated .... Thanks in advance.

Hi all,
does the shrinking of the database affect the data in the database, such as will it change the data, or deleting the data away?
Thanx

I've read lots about why you shouldn't normally shrink databases in posts such as this:
[URL]
But we have a situation where we are required to copy the live db to various non production environments for testing. Part of this process involves truncating a number of tables with masses of blob data. So we're freeing up quite a lot of space. The question is how to reclaim this? The database is peculiar in that it's got no clustered indexes so I can't rebuild indexes on another filegroup with drop to move and rebuild.
I've tried dbcc shrinkfile specifying a size. I've tried to shrink the file in increments. The problem is I'm just not getting much space released. I get maybe 2-3%. I suspect this is because we're dealing with heaps with some tables that have sparsely populated blob / image data.
Is there an alternative to shrinking? Should I recreate all the db objects in a new database? It doesn't matter if the process takes a while or if it has to be done manually.

Hi,
We have a database in production which has free space about 200 GB in Data files and Index files, I want to shrink Data files and Index files.If I do incremental shrink in daytime does it hurt the performance of the database or please advise what is the best practice.

Hello,I am trying to clean up a database I inherited.I have an 80GB SQL 2000 database with 20 datafiles each 4096 in size. Ihave been able to remove unneeded data and am now trying to clean up.If I do a Shrink on each datafile would able to recover on average 2gbout of 4g, however I would prefer to have 10 full datafiles and 10empty. (or better yet 5 full 8GB datafiles and 15 empty)Can someone point me in the right direction on how to move the dataaround so that dont have 20 partially filled datafiles?I have noticed that I can shrink a single file and use the "empty thefile option (and move data to other files in the group)." option. Ihave already done this to the last 2 datafiles as a test but not surehow to do this on a large scale. I have also set the 1st 10 datafilesto be able to grow to 8 GB.For lack of a better way to say this, Is there a way to defrag orreorganize the data ables so everything "moves to the front".BTW, I have already run a maintenance plan to reorganize the data andindex pages.

Hi there,
I have a large (420GB) database that has never had data archived off before. I taken a backup to a test server and run a script supplied by the product vendor which has removed a large ammount of old data no longer required.
I have checked within enterprise manager that this data has now gone, however the actual file itself has not shrunk in size. Is there a further step I need to take to get back the space.
Kind Regards

1) Does shrinking a db have any side affects ? Or this is pretty much a normal
operation ?
2) Also in db options, is it recommended to have auto shrink checked ?
Thanks for your help.

I have a webhost where it seems my control of my database is fairly restricted. I cannot backup the database because I don't have the necessary permissions. I cannot perform a DBCC SHRINKFILE (permissions) - and many other DBCC commands. I ran into a problem where my log file filled up during the middle of the day and impacted my operations - data was lost.
I found some TSQL for shrinking the log file, but the statement:
SET @TruncLog = 'BACKUP LOG [' + db_name() + '] WITH TRUNCATE_ONLY'; EXEC (@TruncLog)
will not execute because I cannot execute the BACKUP LOG command (permissions)...
Is there anything else I can do, or am I to far up the creek (w/o my paddle)??
Thanx
Jerry

HiRunning SQL 7 sp3 on NT 4
I have a database that has the auto shrink option turned OFF. However, the log file seems to auto shrink after the user
runs bulk insert.
The log file is not setup to auto grow either.Any ideas.
Thanks,

I've been trying to shrink my SQL 7 Transaction log after it had grown to 30+GB's. After running the command dbcc shrinkfile 'filename' and the new size, I'm getting a result set of:
DbId FileId CurrentSize MinimumSize UsedPages EstimatedPages
------ ------ ----------- ----------- ----------- --------------
6 2 640 128 640 128
(1 row(s) affected)
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
However my transaction log remains the same size. Any advise would be appreciated!

I'm having a problem shrinking my transaction log. I have a 1GB database with a 500MB transaction log. The transaction logs are backed up every 10 minutes but it has grown to 2.2GB. I've tried backing the transaction log with TRUNCATE_ONLY and then tried doing a DBCC SHRINKFILE but it doesn't seem to work. I've checked if there were any old, long running queries but there is none. What else can I do to reduce the transaction log size?
I've had a thought to create a secondary log file and then delete the primary but that isn't allowed. Is there anyway I can make the secondary log file the primary and vice-versa? This way I should be able to delete the secondary log file to reclaim space.
Any assistance is appreciated...
Many thanks,
Michelle

We have a database that was created with a 50 MB transaction log, that is set to autogrow. Due to activity the log periodically grows to over 200 MB. So we expanded it to 200 MB. But everytime the log is backed up, it shrinks to it's original size of 50 MB. The autoshrink option is not set, and no one is manually shrinking the log.
Any idea what could be causing this?
We are using SQL 7, SP 3.
Thanks!

Hello,
Ran the Andrew Zanevsky script to shrink the Tran log, this works great, but say the log gets shrinked to 30MB, I then expand it to 40MB, then sometime within a 24 hour period it magically gets reset to 30MB. The database is a standalone DB, and is on SQL7 SP1 the script I ran can be found @ http://www.pinnaclepublishing.com/sq/SQMag.nsf/WebIndexByIssue/F36C151BD80FAD8F852568D0007799BE?open.
Can anyone please give some insight into this or maybe a flag that got reset somewhere?
Thanks in advance

HI-
I've got a development server where I periodically have to allow the tempdb to grow to over 2GB. However, I'm at a loss on how to shrink the tempdb back down to a manageable size. I need the drive space on the server for other tasks. This seems like such a simple thing but I can't find information anywhere on it.

I have a database that is 9 Gig in size and I am no longer needing the information that was stored in this database.
So I deleted the User tables that I created and deleted the User stored procedures.
I performed the Shrinking database feature and it only shrunk my database to 2 Gig.
How come it did not shrink the database to at least 10 MB since I no longer have data stored in the database?
