Shrinking The Log File
Apr 25, 2002I have a 13 Gig Log File with only 121 Mgs of space used. I have run the DBCCSHRINKFILE command and it has shrunk it by about 100 Mgs. Why can't I get it to shrink to a reasonable size.

Shrinking The Log File
Sep 15, 2000Hi, is there any other way to shrink the log file other than truncating every time it gets bigger... I have a 800MGs database and the log is getting as big as 11Gigs... any suggestions other than truncating it? Is there a way to set it off?

Nov 29, 2000I'm trying to shrink the log file. I have used the suggestions that I have seen posted previously. This is the script I've been using.
DECLARE @DB VARCHAR(40)
SELECT @DB = 'PBDSSTEST'
CHECKPOINT
EXEC('DBCC SHRINKFILE ('+@DB+'_log, 1, NOTRUNCATE)')
EXEC('DBCC SHRINKFILE ('+@DB+'_log, 1, TRUNCATEONLY)')
CREATE TABLE t2 (char1 char(4000))
DECLARE @i int SELECT @i = 0 WHILE (@i < 300) begin INSERT t2 values ('a') SELECT @i = @i +1 END DROP TABLE t2
BACKUP LOG PBDSSTEST TO PBDSSTESTLOGBACKUP
Before I ran this the used portion of the log was 1795.12 MB, the free was 1570.50 MB for a total of 3365.62 MB.
After completing this the used portion was 25.62 MB, the free space was 3263.50 for a total of 3289.12 MB. It only srhunk about 26 MB. Why won't it shrink it anymore. There was plenty of data in the used at the time of the shrinkfile command so I would have thought it would have shrunk it a lot more.
Please help. I don't understand why it won't shrink it anymore than it did.

Shrinking Log File
Aug 29, 2007
I have a problem with shrinking a log file on SQL 2000. The log file has grown to 25gb (the db is 30gb) . The DB was in simple recover mode but I have changed it to full so that the log file can be backed up. I have run the dbcc shrinkfile on the log file several times (plus log file backups) and it has increased the logfile size. Each time I have run shrinkfile I get €˜Cannot shrink log file 2 (db_Log) because all logical log files are in use€™ message. I have used the dbcc loginfo command and this shows that all the virtual log files are in use. The db also publishes 4 snapshot replications. Any suggestion for how I can easily shrink the log file?
thanks

Shrinking 2000 Log File
Aug 13, 2001I have a database that was loaded with large amounts of data before today. I backup up the db and trans log. presently the DB file is 328 while the trans log show 428 meg with only 28 meg being used. If I try to shrink either the database or the log files, the log file wil not shrink.. It tells me to set it to a minimum of 28 meg but still not shirnk. I realize this was a problem in 7, any quick fixes, in a hurry. Running SQL 2000 SP1
View 1 Replies View RelatedAutomatic Log File Shrinking
Oct 16, 2007I'd like to create a stored procedure to automatically shrink the transaction log file on a certain database monthly. As I am not the DB admin (it's a web-based db on a remote server), I'd like to put together a script to create the procedure so I can just send it to the DB admin to run. It seems like it should be pretty easy, but I'm still pretty new to SQL server. Is anyone able to give me some pointers?

Dec 13, 2007
I have a relatively high usage 2005 database whose transaction log grows every day.
Untill now I have been manually shrinking the log files .. but I would like to automate this process.
In the maintenance schedule that runs every night
1 Do a full backup to disk
2. Do a transaction log backup to disk
3. run the following TSQL
USE [MyDB];
GO
ALTER DATABASE MyDB
SET RECOVERY SIMPLE;
GO
DBCC SHRINKFILE (MyDB_log, 3000)
GO
ALTER DATABASE MyDB
SET RECOVERY FULL;
GO
4. Backup disk files to tape.
however it doesn't work !! the TLOG file does not shrink, even though its the same as the manual job that I run?
There is nothing in the SQL logs .. but in the event log I get
Event Type: Error
Event Source: SQLISPackage
Event Category: None
Event ID: 12291
Date: 13/12/2007
Time: 00:50:10

Difference Between Shrinking A DB And A FILE
Jun 14, 2006Hi,
What is the difference between shrinking a DB with that of a file.
When you select a DB to shrink will it not shrink all the files in it.
Because when I select Files to shrink it does not prompt me with
a specific file.
So I am confused as to why SQL server 2K5 asks if you need to shrink DB or FILE
Tnx
Shrinking The Log File On A DB That Is Mirrored
Nov 17, 2006
Hello,
I'm having couple of DB that are mirrored.
my concerne is regarding the Log file size.
I'm running the following steps:
BACKUP DATABASE [DBName] TO DISK = N'Backup_File' WITH NOFORMAT, INIT, SKIP, NOREWIND, NOUNLOAD, STATS = 10
then
BACKUP LOG [DBName] TO DISK = N'Backup_File' WITH NOFORMAT, NOINIT, SKIP, NOREWIND, NOUNLOAD, STATS = 10
if I try to run a SHRINKFILE (DBName_log, 20)
I receive the following info:
Cannot shrink log file 2 (DBName_log) because all logical log files are in use
I'n a bit tense using a
BACKUP LOG [DBName] WITH TRUNCATE_ONLY
as it's part of a mirroring.
but I need to reduce the size of the log file.
thank four your suggestions

Problem Shrinking Data File
Dec 3, 2007(SQL 2005) I have a few databases that are currently hovering at around 150GB. (The following only concerns the .mdf) Of this total size, only about 90GB is real data. The other 60-70 is data from unecessary audit tables. Recently, we've been having some space issues on a 1.7TB server. We've decided that deleting these audit tables and reclaiming the 60-70GB per database is the route we're going to take.
What we did: DELETE <table> (per audit table). Now, it shows that the database size is ~90GB and there is the 60-70GB of unallocated space.
Then, we ran a DBCC SHRINKDATABASE (db_name) overnight. Checked space the next morning and only about 10GB had been reclaimed. We've tried a number of other alternatives of which, none have been successful.
(DBCC SHRINKFILE(file, space), drop and recreate tables, etc.)
Can anyone think of any reason why these commands would not be working? If I can provide any additional information, please let me know.
Thank you in advance for any input!
Shrinking 27GB LDF File (solved)
Jan 8, 2007Hi,
I have an interesting problem here. I am running SQL Server 2005 and have a large database. After running some scalability tests over the weekend my MDF file size went up to 25GB and LDF file size went up to 27GB filling up all available disk space. I didn't do any backups, so it is understandable why the LDF file size is so large.
Now I am trying to shrink the LDF file. However, DBCC LOGINFO indicated that all LVFs within the LDF are active (Status = 2). I detached the database to make sure no active connections exist and ran CHECKPOINT, but still DBCC LOGINFO lists all LVFs with status 2. Since all LVFs are up to date I can't shrink my LDF file.
Why are all LVFs still active after detach/attach and checkpoint?
How can I shrink the LDF file?
Thanks.
Alec
Ex Post Shrinking File Sizes
Jul 20, 2005Is there a fairly quick and dirty way to shrink the file size allowedfor a DB on SQL server after the DB is in use?Our old DBA allowed 3 gb for log files and we don't need nearly thatmuch. However, the space is still being used and reserved. Can Ishrink that "maximum" and clear up the space?I don't want to just copy all the tables and primary keys and open anew one with the new data, though that is plan A right now.I cant just change sysfiles, it yells at me.

DBCC Shrinkfile Not Shrinking Data File
Jan 31, 2002On 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.

Oct 12, 2002Gurus,
I have inherited a SQL 2000 database ( (I am new to SQL DBA) and I found this when I was checking the db properites . The transaction log has grown bigger than the actual data file, I thought transaction log backups would truncate the inactive portion of the log file and shrink the transaction log, but it was not the case it seems, may be it was truncating the inactive portion of the log, but not shrinking it. This site does not have a job for truncating the data/log files periodically. What is the best method to deal this situation, how can I shrink the Transaction log quickly?,
All your suggestions are welcome.
TIA,

Shrinking Database File After Removing Data
Apr 20, 2007Hi 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

Mdf File Become Smaller And Smaller After Shrinking Db

Shrinking The Transaction Log
Feb 1, 2005I 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

Shrinking Transaction Log
May 3, 2001I'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!
Shrinking Transaction Log...
Aug 28, 2001I'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
Transaction Log Keeps Shrinking
Oct 18, 2001We 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!
