View 4 RepliesHi, I am trying to automate shrinking the transaction log file on SQL server.
Every so often we get errors with our application using SQL server, in which I resolve by running the backup log and shrink log commands. However, recently I got the error: Could not allocate space for object 'table_name' in database 'database_name' because the 'Primary' file group is full. To resolve this I had to create another transaction log and then run the backup log and shrink log commands.
I know need to automate the process of shrinking the log file. I have checked and the Auto Shrink checkbox is ticked but these errors still occur.
How can I delete the additional log file I created and automate this task of shrinking the log file within SQL server? Any help would be appreciated...Thanks
what's this : "auto shrink " db option in properties ???
in which case may i use this option ?
please help
I am actually a newbie to asp.net and i m using ASP.net 3.5 i.e, VWD 2008. i am using it for the first time as my tool to develop a website for my final year project. i am planning to develop an online job recruitment site like www.monster.com. Rigth now i am confused how will i manage my database. i've learned to use databinding concept of SQL SERVER in VWD 2008 but will it be enough to handle such huge # of Job postings and employers and as well as Resumes in pdf of word format? or do i have to create a separate databse in SQL Server and to connect it with my website? i am confused at the moment. please help me in this matter.

I am using MSDE in sql server 2000.
When the database data file size exceed 2G limit, I tried to shrink the db and it
reduced by about 100MB.
2 days later, I checked the db data file size and it was reduced to 550MB, which is
1/4 of the original db size!
Please kindly explain the reason of this case, and how can it be monitored
effectively?
Thank you.
I would like to do an update statement to set auto shrinks to zero. A value of one means they are on. I have been using this select statement and manually changing them, but can't use it in a where clause.
select name, databasepropertyex(name, 'isautoshrink') shrink
from master.dbo.sysdatabases
I would like to do "where shrink = 1", but it won't work.
Any suggestions?
Hi,

Hello everybody,First: SQL Server 2000 sp3a, HP cluster server, MS 2003 server,database recovery model simpleTorn page detection:When I have this option turned on, processes conected with updating andwriting in database, was MUCH more slower, than if I've this optionturned off.It seams to me, that when this option is turned on, the sqlserver ismuch more slower by any operation connected with writing, than withoutthis option.This option is required for ensurance, that the data are writtenproperly on the media.My question is:if I have my database running under cluster, with RAID hd system, whichcontains write cache, with additional checking, that the data will bewritten correctly, is it necessary for me to keep this option turnedon?Auto shrink:When it is turned on, does it affect performance?Personaly, I don't think so, but somebody is insysting on it, and Iwould like to have an information from independent source about that.Best regardsMatik
View 13 Replies View RelatedIs it possible to manually force/call/start the system AUTOSHRINK process? I have an issue that appears only when the engine shrinking process is running and I need this to reproduce my bug.
I know how to start a "regular" database shrink process with:DBCC SHRINKDATABASE(xxxx);, but this is not the same as one started from the database engine.
We're using SQL2000 on Windows 2000 Server, but this is a problemwe've had on one particular database since SQL7 on NT4.The database in question is set to autogrow by 10% (currently sittingat 31Gb total size). However, last week users complained of aslowdown in performance. When we checked we found that only 14Mb wasfree on the database (we thought it would've grown automaticallybefore then), and when we added an additional 1Gb manually performancepicked up.Does SQLServer wait until all the space is used up (i.e. 0% free)before autogrowing? Even at that, we've never actually had thedatabase grow automatically - we've always had to add space manually.Settings on this database, and one that does grow automatically,appear to be the same (have also checked via sp_helpdb). So wheredoes the problem lie?Any help you can give would be greatly appreciated.

I'm currently using SQL Server 2005. Before I have set my database on unrestricted auto growth. But today, I have noticed that the Log file has been set to limit its growth to 2,097,152 MB. I have 160GB space for my log files, I just want to maximize the space for logs in my hard drive.
When I try to change the settings back to auto growth it still keeps on returning to its previous setting it is still set on 2,097,152 MB. What I did was :
Right Click on the Database - Properties - Files - Click the (...) - set the auto growth option to unrestricted - Click Ok
But when I checked log file, it is still set on 2,097,152MB.
Can some one help me change the settings of my Database.
Is there any option to set auto fit the cell size of a table in SSRS 2005?
Thanks
I've production sql server 7 sp3 on windows NT. I had a 8GB data file ofwhich 5GB were used and 3GB were unused. I wanted to take back the unused3GB.So I did the following with EM GUI:1. I tried to "truncate fre space from end of the file". Didn't truncatethe file. I believe there was no empty space at the end of the file.2. Next I chose the option to "shrink file to 5GB". And to my horror thedata file instead of taking just 5GB took the empty spaces also and the sizeof the used data file went to 8GB.Any idea what's going on?TIA,SP

On a database with a log file that has an unrestricted file growth, the file size exceeds 1 GB. Since this excessive was caused by a badly written update statement, I want to reduce the size to about 200MB.
After reading the BOL I was convinced that I only need to take two actions: truncate the log file (to create some free space in the log file)and shrink it.
These are the statements I executed:
backup log ODS with truncate_only
dbcc shrinkfile (ODS_Log, truncateonly)
After I executed these statements - BTW, there were no errors - the file size was still the same. Can somebody tell me why?
Thanks,
Stef
Hi,
I have created a new database in SQL Server 7 with the auto grow options set to on. I then added a whole load of new data to the table which made the transaction log file grow to 20Mb.
I then truncated the transaction log to remove all the completed transactions. The Enterprise Manager now shows the Log to only have 3MB of data in it but the file is still 20MB.
I have tried setting the truncate log on checkpoint option, and tried running DBCC SHRINK DATABASE and DBCC SHRINK FILE commands but these seem to have no affect on the file size.
Does anyone have any idea what I might have missed/done wrong?
Yours well and truly stuck,
Martin
I have Disk Xtender 2000 which was made by OTG Software , Legato and now EMC. I have an NT 4.0 PC with Microsoft SQL 2000. I have a drive space problem and need to shrink a 38 gig .ldf file called OTG03.ldf I also have a 2 gig .mdf file called OTG03.mdf How can I shrink this .ldf file. I'm not a DBA so being specific is greatly appreciated.

View 8 Replies View RelatedI am geting growth alerts and need to shrink a log file that is 99% full, but it won't let me. Here is the message I get.
The transaction log for database 'SOM_System' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases
What can I do in order to shrink this log file??
Thanks
I have noticed many times, even after log backup, shrink file (SSMS) is not reducing the file size. Even though there is free space shown in SSMS.
Subsequently I change the recovery type to SIMPLE and shrink – that does the trick for me.
Does anyone know why does this happen? Is there a better solution?

Hello,
I have a database that the '.mdf' file is just huge. The physical size on disk is approximately 110 gig. I run weekly maintenance plans to rebuild the indexes on it.
I ran the 'sp_spaceused' command and got the following results:
database size: 106996.25 MB
unallocated space: 9614.35 MB
reserved: 99716504 KB
data: 13968056 KB
index_size 4002184 KB
unused: 81746264 KB
I was trying to clear the unused space, the numbers are telling me that I have 81 gig of space unused, but no matter what I do the '.mdf' file will not shrink.
I ran the following command: DBCC SHRINKDATABASE ({dbname}, 10,TRUNCATEONLY)
Any thoughts?
Thanks for the help

First off, I'm normally not one to shrink the hell out of data files (for obvious reasons), but this is a special case. We are setting up a mini test environment in preparation for migrating one of our systems to SQL Server 2005 (among other things).
The problem I have is that the test SQL Server I have to use has only about 50GB of disk space that I can allocate to databases, when the databases that I need to fit in there sit at around 130GB total. I've got 13 total databases that I have to fit in there. There are several logging tables in each, and lots of binary data that's really not needed for our testing. The first thing I did on my testing copies was to change the recovery model to simple, which chopped the log file.
So I've been truncating the logging tables and have been stripping out the unneeded data. I then have been running a script that I wrote to reindex, then shrink the individual files, then the database as a whole. Probably overkill, but it has worked on all of the DBs with the exception of one.
This particular DB is approx 21GB in total size (it's already come down from about 55GB), but when you look at the free space, it's showing 75% free inside the mdf file. I don't really care much about performance at this point, I just need to get the file size down and can't figure out how.
Any ideas?
BTW - this is the script that I wrote:
declare @tablename varchar(255)
declare @logfilename nvarchar(200)
declare @datafilename nvarchar(200)
declare @dbname nvarchar(200)
declare @sql nvarchar(1000)
set @dbname = ltrim(rtrim(db_name()))
set @logfilename = ltrim(rtrim((select name from sysfiles where lower(filename) like '%.ldf%')))
set @datafilename = ltrim(rtrim((select name from sysfiles where lower(filename) like '%.mdf%')))
/* Reindex Tables */
declare tablecursor cursor for
select '[' + table_schema + '].[' + table_name + ']' from information_schema.tables
where table_type = 'base table'
open tablecursor
fetch next from tablecursor into @tablename
while @@fetch_status = 0
begin
print 'Reindexing ' + @tablename
dbcc dbreindex(@tablename,' ',90)
fetch next from tablecursor into @tablename
end
close tablecursor
deallocate tablecursor
/*Shrink the crap out of the DB*/
set @sql = 'BACKUP LOG [' + @dbname + '] WITH TRUNCATE_ONLY'
print @sql
exec sp_executesql @sql
set @sql = 'DBCC SHRINKFILE([' + @logfilename + '], 1)'
print @sql
exec sp_executesql @sql
set @sql = 'DBCC SHRINKFILE([' + @datafilename + '], 1)'
print @sql
exec sp_executesql @sql
set @sql = 'DBCC SHRINKDATABASE([' + @dbname + '], 1)'
print @sql

I have a table that among other holds volume data. I need to calculate something called Intelligent Volume based on set of rules.
After all rules were followed and I still find data that does not belong to any of the rules this data is bad and needs to be reported on (can not be discarded)
I wanted to do this is sql task (insert intel. volume) and I am using Cursor to loop through all the data and all rules.
How do I redirect this data to a file so we can report on those records?
Thanks
I have a database (sql server 7.0) that has some big unused space in the transaction log. I tried to shrink the transaction log, but it seems it is not working. I used the same procedures to successfully shrink the log file for database of SQL Server 2000.

shrink database from the Enterprise Manager.
or
dbcc shrinkfile (Spoper_Log, 40)
backup log Spoper with truncate_only
Does anybody know how to shrink the transaction log in SQL Server 7? This is a production database and I can't afford to lose any data.

I have read around and seen the suggestion to make a new database file and copy all the data to it. How is that done? I am using SQL 2005 Express with microsoft SQL server management Studio express.
I am having DB with 4 ndf and 1 Mdf, In properties
1.MDF- Intial Size 5GB and Autogrowth 5GB
2. 5 NDF- Intial Size 20GB and Autogrowth 5GB.
So we are using the template and creating DB's.S o we have more than 30DB on same size. But Sometime actual data was very low not even 15 GB.
is it good if i shrink the DB?
