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?

What is the recommended size and file growth for a database and log file? We will be storing approx 10000 records a day.Currently we have the following:
CREATE DATABASE Dummy
ONÂ
PRIMARY
( NAME = Dummy_data,
  FILENAME = 'D:....DATADummy.mdf',
  SIZE = 250MB,
  FILEGROWTH = 25MB )
LOG ON
( NAME = Dummy_log,
  FILENAME = 'D:....DATADummy_log.ldf',
  SIZE = 50MB,
  FILEGROWTH = 5MB ) ;
GO

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?

We have installed SQL Server 2008 R2 SP1 instance and it's having Share Point 2010 databases.
We have 2 dedicated drives for Tempdb on SAN with 50 GB space. Both tempdb data & log files are created with default size. I would like to presize them.
What are the best values to start with?
U ->Tempdbdata having tempdb.mdf file
V->Tempdblog having templog.ldf file

I am having a problem with the growth of the tempdb on my SQL 7.0 box. I have over 300+ stored procedures that are running (many with group by and order by in them). This is causing the size of my tempdb to grow to over 30gigs in size. If i reset the services of the DB it shrinks back down to the managable 6 gigs that i expect. Is there a way to have the services restart automatically on a nightly basis or is there a way to have the tempdb deallocate resources once they are used without restarting services?
I apreciate any help you can provide,
Nathan

Iam close to Production on our new SQL Server Environment.
How do u typically manage Disk Space (Particularly tempdb)
-Would you have a Job to run during Non Usage Hours to Shrink the Tempdb?
OR
-Would you have the Autoshrink ON?
What is the best approach?

:eek: I am somewhat confused -- I have a database in production that I restored to a QA environment; upon restore, the size has grown by 200MB.
Both production and QA are running SQL2000 -- the only difference is that QA has the latest security hotfixes installed -- version 8.0.0.665 from KB article at the following link:

We have a nightly application that when run during SQL Backup caused a single table in a 7GB database to increase to 13GB. Total database size reached 20GB when the disk array ran out of space. Table only contained 661,000 records and should have been less than 100MB.
Recently we have moved from SP1 to SP3.
HELP !!!

I'm aware of the issues with sizing your logfile growth size too low (causing too many VLFs, etc). But I haven't seen much about the datafile side of it.
Are there any benchmarks specifically on setting datafile growth so low (on databases 1-100Gb in size)? Are there circumstances in well utilized servers where that might be warranted?

Any good starting point to understand for a specific db, how many max VLFs are good to have so that it does not cause long startup or backup times?
Also, I need some calculation so that I can identify a best growth parameter I will setup for each database ?
I'm seeing the below msg in errorlog and curious to know the changes (right sizing/growth) to be done? As of now 100 MB of log file growth value is set (refer: [URL] ....)
Database BizTalkMsgBoxDb has more than 1000 virtual log files which is excessive. Too many virtual log files can cause long startup and backup times. Consider shrinking the log and using a different growth increment to reduce the number of virtual log files.

I am trying to resize a database initial log file from 500M to 2M. I€™m using€?
ALTER DATABASE <DBNAME> MODIFY FILE ( NAME = <DBLOGFILENAME, SIZE = 2 ) "
And I'm getting "MODIFY FILE failed. Specified size is less than current size." I tried going into the database properties and setting the log file to 2M, but it doesn€™t keep the changes.
Any help with this process?

We have a large 'History' database that is currently about 4.5TB, with most of that in a datafile that is 4.2TB. We wanted to stop growth on the one large data file and have SQL Server allocate new data to the other data files, but this throws an error when we attempt to change the MAXSIZE settings:
ALTER failed for Database 'History'
MODIFY FILE failed. Specified size is less than or equal to current size.
The SQL Server is saying we can have a max size of 2TB, and anything over that is blocked. Since this is being blocked, the file continues to grow.
Is there any way to cap the growth of the 4.2TB file and not allow any more data to be written to it?

Hi all,
I have recently setup a transactional replication in MS SQL 2000. After setting up the replication the clients TempDB grew by almost 60GB. Now the client is Blaming me for the TempDB GROWTH and saying that its because of the replication being setup i tried to convince them but they are not satisfied yet. Can anybody please tell me does replication cause the tempdb to grow. If yes then how. can u suggest any good link for getting to know the internal working of SQL Server replication????
Thanks in advance

I have an SQL server that has probably 20 or so people connected at a time. In addition to these people, there are five people that run Crystal reports with some voluminous data, usually coming from views.
About every week and a half, one of the report writers get a message that the master device is full and must be expanded, because tempdb is full. When I expand temdb, it fixes the problem.
My question is, the tempdb is now 800 Megs. The sum total of memory allocated to all of the other(besides master)devices is 650. Should this be a flag that something is wrong? It just keeps growing and growing. Tempdb is not on it's own device-it is still on master.
Any advice would be greatly appreciated!

when I restart SQL server my tempdb database is 1.9Gb. I thought it was deleted and replaced with a copy of the model database. Is this not so?

I have read that MS suggests you tempdb be atleast 25% of your largest database. Is there any way to monitor your tempdb to determine if it is filling up or being 100% utilized and needs to be expanded?
Thanks,
David

I have a server with 2.5GB of RAM. I am allocation 1GB to SQL Server and am attempting to put 500MB tempdb in RAM. It would appear as though I am hitting some sort of max threshhold that I am unaware of as I can set tempdb in RAM up to 320MB. Anything beyond that and I get the following errors on start up and SQL Server will not start.
98/12/02 08:25:47.03 spid1 Clearing temp db
98/12/02 08:25:47.03 kernel udactivate(IN_RAM): Operating system error 8(Not enough storage is available to process this command.) encountered
98/12/02 08:25:47.03 spid1 Device activation error. The physical filename 'IN_RAM' may be incorrect
98/12/02 08:25:47.03 spid1 crdb_tempdb: Unable to move tempdb into RAM; RAM device doesn't exist, cannot be created, or doesn't have enough space for tempdb
I am certain that I am not hitting a Physical RAM limit and the memory checks out and is visible to NT. Please Advise. Thanks

Hello Everyone!
Is there any way by which I can determine whether the tempdb size for the SQL Server is enough or not? (I ean are there any symptoms like excessive paging etc. that can identify this bottleneck?).
Thanks!

We had a runaway query which built the size of tempdb to 24000mb. Then someone changed the unrestricted file growth property to restricted growth while the size was 24000mb. Now I can not reduce the initial size. I have set the property back to unrestricted file growth. I have shrunk the tempdb and available space is almost 24000mb. I have stopped sqlserver. I even deleted the existing tempdb.mdf & tempdb.ldf files. But when SQL server is restarted, the initial size is set to 24000mb. It will not let me reduce the size. Is there anything short of manipulating the system tables to reduce the size back to 500mb?

We currently have a hard-drive size of 3.89MB and 3.3MB is being used by tempdb. I have tried shrinking the database truncateonly but this is not working. The problem is that the tempdb file is as large as my C: drive size. In addition can this be moved to another directory. For example can I move the tempdb.mdf and ldf from C: to E:. Any help would be greatly appreciated.

I have a tempdb that was created at 1Gig. I don't know why but I want to shrink it below the original creation size. Is there a way to shrink this file or create a new file and delete the old?
I have tried shinkfile and shrink database with no luck.
Thanks Jeff

Against my better judgement, we are using fixed allocations of tempdb on some of our servers. This is to deal with specific limitations of our applicaitons and hardware configuration that I'm not allowed to discuss in much detail.
The problem that I have is that the present plan is to configure the data file at around 18 Gb and the log file at around 2 Gb. This seems just plain wrong to me, but I haven't been able to find a formal recommendation that gives any relative sizing. I would expect to have about twice as much log as data space, especially for tempdb.
Does anyone know of a formal citation (preferably from Microsoft) that discusses this?

I have got SQLv6.5 SP5a with SMS1.2 SP4 on seperate Alpha boxes. I have automated the backups so they are scheduled for after hours. SMS gets backed up first and TEMPDB shortly afterwards. However, since a back log in SMS MIFS has happened, the TEMPDB backup displays of 100,000pages backed up. When you back it up on its own, it only shows 170+ pages.
The SMS DB is 600MB in size, the Log is 210MB, Open objects is 5000, and TEMPDB is set 210MB on its own device.
Any ideas

SQL Server 6.5
I am running a Query in my Production Server. It is hardly taking 15 Mins. The same Query is taking more than 3 Hours in my test server. I can see the only difference between these two servers is Tempdb Size. Will tempdb size matters the performance of a Query. Can anyone reply me?
Thanks in Advance

My prod server (only default instance) is configured TempDB 1024 MB data and Log 200MB. when I run 'sqlperf logspace' it shows most of time around 45% 'log space used'. There nothing going on the instance when I ran 'whoisactive' and select * from sys.sysprocesses where dbid = 2!!!
So my questions are is this normal to see log space around 45%, how to find what what CAUSED the tempdb log space to grow 45%? Is there something to do about it?
