I'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?
View 1 RepliesMy transaction log blows out to more than 55 GB when I run an index rebuild on a fairly large table. It’s ok for the transaction log to get that big but I want to shrink it back down ASAP while maintaining the integrity of my transactional backups. I’m thinking of a process something like the following:
1.Full database backup
2a.BACKUP LOG database-name WITH TRUNCATE_ONLY
2b.dbcc shrinkfile(2,20,TRUNCATEONLY )
3.Full database backup
Is this the best way to shrink the T-Log while maintaining the integrity of my transactional backups?
My database is MSSQL 2000 sp4 in full recovery mode.
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.

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?
View 1 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.
DECLARE @DB VARCHAR(40)
SELECT @DB = 'PBDSSTEST'
CHECKPOINT

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.
When I try to shrink the log file for my databases I am getting following message.
Cannot shrink log file 2 (cm_archive_mp_Log) because all logical log files are in use.
what should I do to successfully shrink the log file.
Thanks.
how can we shrink the log file to the required size without affecting the live database .....
Thanks in advance
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

I 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

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

Hi,
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
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

please advice me what does .ldf file consist of and can i shrink the .ldf , is it adviceble to shrink after the backup and how frequently it can be done on a production db
please advice me ,can i shrink the .mdf , it is adviceble to shrink after the backup and how frequently it can be done on a production db
Thanks
(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!
Hi,
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.

Is 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.
View 1 Replies View RelatedI've been searching and reading for best practices on how to maintain a reasonable log file size while engaging in Log Shipping. I have found plenty of information on these subjects on their own, but not on how best to shrink your log size without breaking your log shipping integrity.
I apprecaite 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.
View 1 Replies View RelatedGurus,
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,

My intention is to include a sql job to schedule for shrinking log files to half of its original log file size (if half of their original size is greater than 5MB)
The code is below. But while executing the code it is keeps on running indefinitely. can somebody throw some light what cause it to go into an indefinite loop.
Thanks
Babu
code:
====
DECLARE db_file_name CURSOR FOR

Where rtrim(lower(filename)) like '%.ldf'
DECLARE @f_name varchar(128), @new_f_size int
OPEN db_file_name

We are using Sql server 2012. One of our production database has hight no of vlfs. We are planning to shrink the logfile to reduce the no of VLFs but the database is configured for logshipping.

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
Hi!
I have a database where I add some new Filegroups and moved some Gb's of
tables and indexes to new file groups.
Now I would like to shrink the source of these tables/indexes: the mdf file.
This means there should be much empty space now in the mdf file.
I tried to use dbcc shrinkfile, but it run for more than one day.
Are there some good strategies about shrinking the mdf file?
I had to restart the instanse because got problem using the db while dbcc runned...
Thank you for help
1. I want to create a flat file from sql server on every night
which will contain data from particular table of that paticular date.
2. I wanna put the file in the particular folder.
3. I wanna give the file name like 'ALT-yyyyddmmhhmmss'
where 'ALT' is some constant and 'yyyy' is year,'dd','mo','hh','mm','ss'
is the day,month,hours,minutes,seconds of the day respectively. So that we can find from the name of the file when it is created.
4.Please suggest me how to go for that.

Hi all:I restored one backup database (7.9 GB mdf) on two diffrent servers. Ishrunk them by clicking "Move pages to beginning of file beforeshrinking".After shrinking, one mdf file is 6.7 GB, and the other is 4.2GB. Ishunk again and again:1. the 6.7GB become 5.9GB, 5.2GB, 4.7GB and 4.2Gb (four times)2. the 4.2Gb become 4.0GB (just one more time)It is wired, I am wondering the mdf will be smaller and smaller if Icontinue to shrink them? What is the reason?ThanksWJ

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
