SQL 2012 :: TempDB Log File Usage Constantly Rising And File Keeps Growing?

Jun 16, 2014

The TEMPDB transaction log file keeps growing.The database server is new and the transaction log was presized to 1 GB on installation. After installing a number of databases, the log file grew over a day to 38GB. Issuing a manual checkpoint was the only way to free some space to allow it to be shrunk back to a usable size. The usage of the file is still going up.

I am struggling to find what process is causing the log to be used so heavily. Looking at the log reuse wait desc for tempdb returns "Nothing" and tempdb itself isn't being used very much or growing in size.

Tempdb Log File

Oct 12, 2007

Hello all I am new here so I am sorry if this question has been asked 1,000,000 times.

First let me describe my environment:

VM-Ware ESX 3.01
3.0Ghz (Dedicated to VM)
3.0 GB RAM (Dedicated to VM)
Windows Server 2003 SP2
SQL Server 2005 SP2
Spotlight for SQL Server
Quest SQL Watch

Now the issue:

We are in current development of a new manufacturing system so the above system is just a development box at this stage. The problem that I am having is that the tempdb log file seems to grow out of control, and if I do not have time to shrink it, I have to bounce the mssql service in order to do anything once the disk is completly full. At one point I even made a job to shrink the log file every 15 minutes to try and prevent the uncontrolled growth.

I have researched this everywhere and it really is starting to get frustrating. I am highly leaning towards the application that is utilizing the database is heavily dependant on #temp tables. So I found this query to return me the top colums being used in the tempdb.


FROM tempdb..sysindexes



And I get the table that is using up the most rows.


FROM tempdb..sysindexes


After doing this I figured out that there is something that is writing to the tempdb around every 15 seconds about 100000+ rows at a time. And the alarming thing about it is that the record "rowmodctr" is already over 1 billion. So that leads me to beleive that this has modified rows over 1 billion times since I last rebooted the server a week ago.

So the main question that I have is. Is there a way to query what is inside that '#4440A7FE' table, so that I can pin it down to a session?

Also I have already said to the development team to use "derived tables" instead of temp tables, but they just fight with me all the time and blame the problem on hardware and configuration.

Please please help me with this as it getting really frustrating I am so sick of shriking that file. And sometimes it grows more that 3GB in less than 15 minutes.

TempDB Placement - One File Per CPU

Sep 8, 2006

I need some help understanding the benefit of creating tempdb with one file per processor. I believe the benefit has something to do with the way SQL Server utilizes processor threads, but I'm a bit weak on the details.

Thanks, Dave

Tempdb File Size

Aug 26, 2007

I have the classic "tempdb-out-of-space" problem. Unfortunately, my server fails to reboot properly as tempdb is located on the C: drive which is now completely full. While I understand the changes required to prevent this from happening again, I want to know if it will even reboot if I delete tempdb.mdf and tempdb.ldf. I've read conflicting information on MSDN about default tempdb file size:
- files are built to the default size (I will be fine)
- files are built to the same size as before (problem)
Which is true for SQL 2005?

Tempdb Log File Is Full

Jul 12, 2007

My Tempdb log file is getting full very frequently. I could see that tempdb log file is not getting truncate automatically since checkpoint is not occuring as execpted.

If a shrink the tempdb its getting truncated immediately and releasing the full occupied space.

So i come to an conclusion that auto checkpoints are not happening even though the tempdb is in SIMPLE recovery model.

I search in KB and could find the article related to this error.

I would like to get it confirmed is the article described is the same issue i am facing. Also if you could let me know the hot fix details for this, that would be great.

TempDB Growth And File Size

Aug 10, 2007

We have a problem with the size of the tempdb.mdf file. The tempdb had grown to 25Gb and consumed all the available disk space. SQL server was restarted and the tempdb was reset back to the default size. The following day the tempdb suddenly increased in size from 200mb to 25GB within a very short space of time. There were a couple of event log entries from sqlservger regarding the lack of disk. Since then the server is running without any problems but the level of free space is virtually zero on the drive with tempdb.mdf file.

What would cause the tempdb to grow suddenly and to this size?

Can I control the size the tempdb can grow to?

SQL 2005 (x64) sp1

Tempdb.mdf Is Nota Primary Database File

Aug 6, 2007

I really needed to move the tempdb file to another hard drive, so I used this bit of code.

USE master

ALTER DATABASE tempdb MODIFY FILE (NAME = tempdev, FILENAME = 'E: empdb.mdf')

ALTER DATABASE tempdb MODIFY FILE (NAME = templog, FILENAME = 'E: emplog.ldf')

Now sql server manager won't even start. The log files says

"tempdb.mdf is not a privary database file. CREATE DATABASE failed. Some file names listed could not be created.
WARNING: problem activiating all tempdb files. See previous errors."

Any ideas on how to make this program work again, without reinstalling it?

DB Engine :: Cannot Remove One Last Data File From TempDB

May 19, 2015

In tweaking performance of tempdb by adding add'l data files I want to reset back to defaults and remove all add'l files I've created.  I was not able to do it for most as they were in use, but by starting the server in single-user mode with all other sql services shut off, and using sqlcmd I was able to use the ALTER DATABASE tempdb REMOVE FILE <tempdev#> to remove the files... except for one.

I have also tried using the command:

ALTER DATABASE tempdb MODIFY FILE (NAME = tempdev#, FILENAME = '<new location');

Restarted SQL server, and tried the ALTER DATABASE ... REMOVE FILE again but am always denied with the message that the file can't be removed b/c it's still in use.

I also tried to shrink it with EMPTYFILE but that also fails with the message that a page is a work table page and can't be removed.

I really need to get tempdb back to just one data file but am unable to find a way to remove this last data file.

SQL Server 2008 :: TempDB Datafile Initial File Sizes Changed?

Mar 18, 2015

I have an instance with 4 datafiles for tempdb each set at initial size of 4G and growth rate of 100MB. After some time the initial file sizes seem to have changed automatically. They now read 3962,100,3688 and 2847 respectively. Is this something done by SQL Server itself? I cannot imagine that it was done manually.

I don't think there was a restart after the initial sizes of 4G were set, could this be related to the problem?

Tempdb Is Skipped. You Cannot Run A Query That Requires Tempdb

Jul 14, 2004

Has anyone seen the SQL Server error:

"tempdb is skipped. You cannot run a query that requires tempdb"?

We're running a .Net web application with a SQL Server 2000 backend, and we get the error intermittently. Restarting the SQL Server service seems to fix it, as it causes tempdb to be rebuilt, but this isn't a long term solution. Any direction or hints would be greatly appreciated. Thanks!

I have never done this before and thought I would ask. Is it possible to detach the tempdb database, move it to another drive or partition, and then re-attach it? What would be the downside or side-affects to doing such a thing?

Thanks. JT
