Hi again
Damn, people, how to shrink log file. I've tried several times with
DBCC SHRINKDATABASE ( database_name , TRUNCATEONLY)
and
DBCC SHRINKFILE (log_name, final_MB, TRUNCATEONLY)
and the log still is _untouched_
I have got big table, about 190 mln records (15 GB) and after simple update the log is very big but unnessesery.

What is the best way to Shrink a Data file and Log Files.
View 1 Replies View RelatedHello,
we are running on sql server 2005 and in some of our production databases the log files are twice as bigger than the data files. we are planning to reduce the log file size. I saw the option on the management studio to shrink the log file. I just have some questions on this.
as long as we are doing on the production server can we do that while the database is online or do we need to take the database offline? any help would be appreciated. Thank you!

Hello everybody.
I have SQL2000 sp3 standard
with 50 db's
All db set for full recovery
and autoshrink
Backup done with Tivoli
full backup once a week
log backup done every 12 hrs
Problem .. shrinking logs
every 20 min I run job
DBCC SHRINKFILE (My_db_logFile) for every db
70% of the time I am getting
message similar to
-------------
Cannot shrink log file 2 (Wholesale_Log) because all logical log files are in use.
--------------
1. I checked with sp_who2
The is no activity on db 'Wholesale_Log' or any other db returning "Cannot shrink..."
Why i getting "Cannot shrink ..." ?
even if job runs right after backup of the log files ,I still have messages.
Thank you

I have a database file LEAR_Index(yes, it hold index data) from a havehave recently removed a bunch of data.It is about 120 Gb, 100Gb of which is not used. I wan´t to shrink thefile to lean 30-40Gb.I´ve been trying this:dbcc shrinkfile('LEAR_Index',40000)But to no apparent avail; the file did not shrink.I´ve tried using enterprise manager for this but it consistenlycrashes when performing this operation.#Any thoughs, idear as to what i might be doing wrong?

I have some doubts about Shrinking databases or files.
while shrinking a file, I learned that we are alllowed to shrink more than the minimum size of the file, does not it bring damage to the data in that file ??
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.
thanks
I've been tasked with taking over the support for a client's SQL Serverdatabase. I'm not a DBA by profession, I'm a software developer whouses SQL Server as a database designer.The clients have reported that the server is running out of disk spaceand examination shows that the log files for several of the databasesare at 5Gb or more.After reading around the subject I suggested the following sequence ofoperations:-- Select the name of the database you want to shrinkUSE MyDB-- Dump unwanted transactionsdump tran MyDB with truncate_only-- Get the name of the logfileSELECT * from sysfiles-- Having examined the rows returned by this use the log file....-- Shrink the file to required size (in MB)DBCC SHRINKFILE('MyDB_log', 10)Is this a reasonable approach? Please bear in mind that I'm pretty newto this, and I have many other tasks to do besides manage the server.A previous DBA has set up good maintenance plans etc. so everything isbeing properly backed up (well, I think it is)If this IS a good approach, would it be reasonable to do this on, say,a monthly basis as a scheduled job? Obviously the stepSELECT * from sysfileswhich gives us the physical name of the log file would be removed andthe job would operate explicitly on each log file for each database inturn.Many thanks for reading.William Balmer.
View 2 Replies View RelatedI have dataware house database and it's size is 2 TB with simple recovery model.I want to reduce it's size because everyday before loading table gets truncate.Is it best practice to shrink the datafiles?database having 5 data files and one log file.what is the best way to reduce?
View 7 Replies View RelatedI have a no of databases in full recovery model whose files are many times their datafiles. It is because these databases were copied from the development servers and in the development servers they were not taking the transactional log backups although once in the production server it is ensured that a transactional log is taken once in a day atleast. I plan to shrink the logfiles using the dbcc commands. However I am afraid that it may lead to severe defragmentation and performance hits.
We are using Sql Server 2008R2 enterprise edition which is clustered.
In this context my questions are:-
1)What is the best course to do the shrinking of log with out defragmentation?
2)Can I do the shrinking when the database is in use or is online in production?
3)Will the shrinking of the logfile improve the performance in any manner like that of the i/o operations or paging?
4)Can I do the shrinking of the log files alone without the shrinking of the corresponding data files?
I am using Sql Server 2012 in always on configuration with multi subnet failover clustering. Size of data file has suddenly increased, i dropped all the unnecessary table from database three days back. day before yesterday i tried shrinking data file using DBCCÂ command but it is taking too much time. is there any other option for deallocating the space.
View 7 Replies View RelatedI have a database which has log file size 300 GB. As the drive is filling up i need to clear the space on the drive, for that i have to shrink the log file.Â
Unfortunately i dont have option to take backup of the database.And i am not able to shrink the file now. Is there any way to shrink the log file with out taking backup of it ?
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 am new to SQL server.
We have many databases for which log files have grown much bigger. The one I need to Shrink immediately has 16 MB .mdf file and 12 GB of .ldf file.
I will very much appreciate, if somebody can help me with step by step process to shrink the database/log file (some way). We are in a crunch situation
Thanks
Hi all,I've deleted a lot of albums but the size of personal.mdf isn't shrinking - how do i go about acheiving this? I've tried to shrink it in sql management express but the file is read only..
please help!
thanks
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

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 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.
View 2 Replies View RelatedI'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
Have a 6G data file in a single filegroup.
Using dbcc shrinkfile to shrink.
Does not have any effect.
Any ideas?
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 all,
I am having a problem truncating a transaction log. The truncate and database shrink commands execute successfully, but do not reduce the size of the transaction log.
Thanks in advance for any help on this issue

Hi, 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?

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?
i havae a database size of 1000mb with used as 507.50 and unused as 492.50. i tried with commands like dbcc shrink file and dbcc shrink database but i could not get the result as what i need. I need to shrink in such a way that it should have 25% of the used space as free space. could any one help
View 4 Replies View RelatedI'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.

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.
Ideally it seems to me that it would be best to only shrink databases when they
are not in use.
However, it seems this may not be practical, therefore can a Database
be shrunk while it is actively being used?
Thanks !!!
Hi, my log has grown out of proportion after performing an indexdefrag in bulk-logged mode!
Now I cant shrink the damn thing coz I have forgotton how to shrink it when the logical log files are still in use.
Can somebody enlighten me please. thankyou.
error msg: "
Cannot shrink log file 2 (MyDatabase_Log) because all logical log files are in use."
If you shrink a production db on server 1 which is using log shipping to restore to server 2. Does the db on server 2 also shrink?
