Shrinkfile And ShrinkDb Don't Appear To Be Working
Apr 20, 2000
Ok, bear with me...I'm new to 7.0. I upgraded one of our 6.5 servers to 7.0 and it went smoothly. I'm trying to shrink the database because I deleted over a million rows. When I do the shrinkdb it runs very quickly The size it shrinks to is the same size it already is!
I tried running a shrinkfile on one of the files...the output said the current size was 640 MB and the estimated size was 88...again it ran but nothing appears to happen.
What am I missing?

I started a database with a log at size 250MB. The log expanded to 2GB before I truncated. It is has a few MB of data and the rest empty. I can't get it to shrink. I've tried DBCC SHRINKFILE (filename) and the GUI front end for shrink database. The data files rearranged and shrunk, but the log file did not. I've had this before and have never figured out what's wrong. Can't get it back to original size at create.

I have a log that has grown unchecked for a long time. I truncated it, used DBCC SHRINKFILE on it, and backed it up. It has not shrunken. I still have a database with an allocated size of 506 MB with 435 MB unused.
I have seen messages that others have posted where they have used DBCC SHRINKFILE without success. It was recommended that they use the sp_force_shrink_log script that is available on the www.sqlpass.org web page.
Has anyone used this script that can tell me how and where to run it? I'm new to this. I tried creating a script using Jobs in the Enterprise Manager and got an error that the command was too long.
Need help!
Thanks,
Veronica

When I execute a DBCC SHRINKFILE or try shrinking database files through enterprise manager it works fine, except when I reboot the server the files return to the original size. Here is the statement I used:
DBCC SHRINKFILE (filename, filesize)
I have also tried using the TRUNCATEONLY option.

Is this supported? Has anyone used it with success? Here's the code I'm using -
EXEC sp_Msforeachdb "DBCC shrinkdb ('?')"

Hi All,
I am having a problem with "dbcc shrinkfile (datafile, emptyfile)". It does not totally empty the whole data file, any idea? It seems like it always leaves 0.06MB behind.

What are the adverse affects of running dbcc shrinkfile.

Hello,
I am wondering if there will be any performance issues concerning executing the DBCC SHRINKFILE action against a production database? So far all I have read, and it would make sense, would be to disable the scheduled Transaction Log Task to ensure that no backup is running against the database. Does anyone else have any more or other information about this subject?
Thanks in Advance, Daimon

Anyone else had this problem ?
I've run dbcc check commands on a 5Gig database which has 2 Gig of unallocated space, with no problems with the tables or database.
However when i try to run dbcc shrinkfile ( on the DATA file ) from Query Analyser the command just runs indefinitely with no response.

Hi!
We made a mistake to run dbcc shrinkfile at the same time with database backup. We stoped and restarted services and run dbcc shrinkfile again. No success.
System doesn't shrink file at all.
What we can do?
Thank you,
Elena.

Hi All,
I have a job that has multiple steps. Step 1 rebuilds the indexes, step 2 truncates the transaction log, and step 3 shrinks the transaction log via dbcc shrinkfile command. The job has been running for quite a while without any problems until this past weekend. The job ran successfully but when I looked at the size of the transaction log, it was the same as before the job ran. I have read on BOL that if part of the logical log is in the virtual logs beyond the target_size mark, SQL Server 2000 frees as much space as possible and issues an informational message. My questions is where is this message stored? How can I read it?
Thanks.

I used dbcc shrinkfile to shrink transaction log, but it worked for only one day. When I checked the properties, transaction log was back to the size I started with. TL was 1586 MB and I set the target size to 1 MB. Any idea why it happened?

Hello,
I am attempting to shrink the disk size of my db log files, using the following command;
dbcc shrinkfile (filename,truncateonly)
The command completes successfully, but the log file size remains unchanged. Am I missing something here? Should the file size be reduced?

How long does it take to execute DBCC Shrinkfile(DB_FILE, emptyfile) on a 10GB datafiles? If you put your datafiles together with the tempdb datafiles on the same logical drive do we have a performance issue?
Thanks

Are there any effects(negative) of running dbcc shrinkdatabase/file on a production box at low/high usage time or high/low activity period of db?

Any body got any ideas how we might get around the following error.
command used:
dbcc shrinkfile('DB_Data',EMPTYFILE)
Result:
DBCC SHRINKFILE: Page 3:9224674 could not be moved because the partition to which it belonged was dropped.
Msg 2555, Level 16, State 2, Line 1
Cannot move all contents of file "DB_Data" to other places to complete the emptyfile operation.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
the file needs to be split from 1 x 200G file into multiple data files in the same filegroup. works for a couple of hours the gives this error, file is still 100G, but has 99% empty space.
Cheers

Hi!
I have filegroup that has to few files.
I added new files (corresponding to number of cores).
Now I'm trying to move data to these new files:
dbcc shrinkfile ('oldfile', EMPTYFILE)
But now there are gone nearly one day and dbcc is not finished yet.
It is stressing not to see some progress.
Is it possible to see in some sys table how much data are moved?
Alternative suggestions?
Thanks

Hello,
I'm running the following command on the machine with MSDE on it:
osql -Uuserid -Ppassword -dlocalmsdedatabasename -Q"DBCCSHRINKFILE('logicalnameofdatafile')"
The command has been sitting with no visible movement (neither the size of the file is changing nor the CPU/Memory changes in Task Manager) for 3 hours already.
Is there anything wrong?
Thanks,
Lana

Hi!
I have an dbcc shrinkfile (emptyfile) running for more than one day now.
But soon I have to restart db service.
Would it give trouble, if I stop service?
I assume, I must run shrinkfile command again?
Thank your for help ;-)

I'm running full recovery mode and doing log shipping so changing to simple mode is not an option.
I'm running BACKUP LOG right before and when I check it says my log is 99% free (on a 180GB log).
When I do DBCC LOGINFO('dbname') right before and after I see a dozen entries and they are all over the file and not just at the starting offset areas. The BACKUP LOG doesn't clean out the file completely.
Is there any explanation for this? Even though I'm doing this at off hours, is it possible that someone on the site in that split second is putting new entries in the log? Why are they spread out though? If they just put entries at the beginning I could shrink the file to a normal size still.

SQL2000 Server, SP4, a database with a 17Gb log file. It has been backed up so all transactions should be validated, now the real file size needs to be shrunk because I need the diskspace plus I want to speed up the backup process.
http://support.microsoft.com/kb/272318/ Tells me what to do but not where to do it.
So I need to run this code : DBCC SHRINKFILE(pubs_log, 2)
but from what console do I run it?

I'm trying to run
dbcc shrinkfile(4)
/*
File ID 4 of database ID 13 cannot be shrunk as it is either being shrunk by another process or is empty.
Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.
*/
The commented lines is what I get in return. There's nothing being executed on this file. I dropped a few indexes. I need the space back from the file. Backups and everything are run on it normally. Is there something I'm missing or is there something wrong with it? I don't do 'AutoShrink'. Also, the file is not empty. Checkdb is working fine. Dbcc ShrinkDatabase also works fine but doesn't even recognize these files. It doesn't even show this files in the results pane when executing the command. Thank you for your help.

On a SQL Server 7.0 database I support, I've been unsuccessful trying to shrink a data file using dbcc shrinkfile (datafile_logical_name, 0). This worked fine for shrinking the log, but of the 4 datafiles that were created 2 shrank successfully and 2 remain unchanged. Unless the information on the General Tab on Enterprise Manager is incorrect, of the 15000MB allocated for one of the files, only 700 MB are used.

Hi,I need to shrink a database file and was wondering whether it isrequired to run a full backup after the shrink operation.In SQL Server 7.0 shrinkfile was a non-logged operation so wouldinvalidate your transaction logs. Is the same true for 2000?Obviously as a matter of course I would backup before and after theoperation but going forward I may want to implement this on a regularbasis.CheersDee

What is the best way to control Transaction log sizes?? The logs keep growing and when I manually truncate
them and use the dbcc shrinkfile command, it doesn't want to shrink it to the specified size. In some cases,
our data file is smaller than the log file. It'll have a Gig of space allocation but only contain 40 megs of data.
Any suggestions on how I can shrink the log file??
