Tempdb Log File
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.


SELECT OBJECT_NAME(id), rowcnt

FROM tempdb..sysindexes

WHERE OBJECT_NAME(id) LIKE '#%'

ORDER BY rowcnt DESC


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

SELECT *

FROM tempdb..sysindexes

WHERE OBJECT_NAME(id) LIKE '#4440A7FE'

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 Log File
Hello when I start executing a transact SQL process, my tempdb file is about 5Mb and It's log file is 1Mb, when the process finishes the log file never gets cleaned again... so It uses a lot of hard disk space and I can't run the process again...

Pd. the process has a "begin tran" and a "commit" at the end...



Could you tell me what to do ???

TempDB Placement - One File Per CPU
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
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


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.



http://support.microsoft.com/kb/909369/en-us†



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
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
W2K3 R2 SP1

Tempdb.mdf Is Nota Primary Database File
I really needed to move the tempdb file to another hard drive, so I used this bit of code.

USE master
go

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

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

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?

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

About Tempdb
Hi

Being new to SQL server I would like some information regarding the tempdb database.

I user SQL Server 2000.

At present I appear to be backing up my tempdb but it has been failing since way back. It gives me this error when trying to bakup the database:

Executed as user: NT AUTHORITYSYSTEM. Backup and restore operations are not allowed on database tempdb. [SQLSTATE 42000] (Error 3147) BACKUP DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed.

Can someone give me a basic grounding as to what the tempdb is used for and should I back it up or not?

Thanks in advance

Neil.

Tempdb In RAM
We are using Peoplesoft HRMS version 7.0 on NT Server 4.0 and SQL Server 6.5, service packs on both up-to-date.

The server is a HP LX Pro with 4 200 MHz 1MB cache processors with 2,560 MB of RAM and 18 9GB drives configured with different combinations of RAID 1, 1+0, and 5.

The database is 2.3GB in actual size with the specific size of 6GB for data and 2GB for log on separate RAIDs.

We would like to use tempdb in RAM to boost the speed of complex queries that use the tempdb for intermediate working tables.

We would like to know of any experience of running tempdb in RAM, issues to overcome, of how to setup.

There are articles and books not recommending using tempdb in RAM. Comments anyone?

Note: Have looked in SQL Server DBA Survival Guide, and SQL Server Unleashed, along with the normal MS Documentation, technet, online books, and knowledge base searches.

Tempdb In RAM
System: Pentium II - Dual 450. 13 GIG RAID. 128 MB RAM.

Everything I've ever heard or seen says not to put tempDB in RAM, citing reasons of negligible benefit or even worse performance as it steals memory from SQL's cache memory.

My issue is I need to take anywhere from 500 to 3000 records (games played) in a batch every five minutes from a table, ordered by game id. There's no guarantee of sequential order to how the records are inserted, so I need to do an ORDER BY in my query. I also do a stored procedure for ranking that requires an ORDER BY.

The performance difference between the two is staggering. 1000 records with a 200 mb tempdb database (not in RAM) takes about 300 seconds. With a 16 MB tempdb database IN ram, it takes just under 127 seconds. Only problem? I'm constantly getting, after a few batches have run, "out of space in syslogs for tempdb ram messages. "

Is there a way to net such performance from tempdb without putting it in RAM, and if not, is there a way to explicity clear out tempdb. Thanks for any help.

TempDB In RAM
Hi,

I moved my tempdb (2MB) to RAM and restarted the server. It did restart but when I tried to connect thru ISQL, it gave me an ERROR -

A connection could not be established to <server-name> - DB-Library. Unable to Connect.

What could be the possible reason.

To move tempdb to RAM, do i just have to change the values of the MEMORY and TEMPDB IN RAM parms and restart or do I have to do anything else.

Please help.

Thanks

Tempdb In Ram Not &#34;going Away&#34;
I am trying to configure a 6.5 server to set the tempdb to run off disk. I reset the tempdb in ram = 0 in the configuration, and restarted the service, but it left it as running in ram, with 0 configured. I then rebooted the server, and it still left the tempdb in ram. Any ideas?

Tempdb
Hi! How can I change the default physical location of the tempdb.
In the setup , you will only be prompted the directory for the software
and the directory for the data.

In sq6.5, you can move the tempdb out of the master device by putting it to
ram and changing the default device. But in sql7.0 it is separated from
the master but the physical device is located the same as the other data files.

Appreciate any inputs..
Thanks.

TempDB
I read an article on this site by Michael Hotek re "Basic SQL Server 6.5 Configuration Options". In the paragraph about TempDB he says that you should always avoid using Temp tables in stored procs. I use this feature a lot when trying to do "not in" type queries (I filter out a portion of a larger table and then use the "not in" on the temp table rather than the entire table.)
Is there a better way to run a Not in query. I have the table well indexed (i think) but it seems to do a full table scan if I use the entire table.

Any ideas???

Tempdb
Hello All~

I have a problem with Tempdb database on SQL 6.5 server.....when i create a temporary table,
i block other users in other databases. Actually i run a stored procedure which creates a temporary table and then the procedure insets some values of a table from my test database. When the spored procedure is executed, users in other databases also get blocked and no new user will be allowd to log on to the server. When i check as to what the other users are executing, i find that they are also creting or droping a temp table.
So i will have to either kill my SP or let it finish and continue blocking other users.

As of now, i am not able to find a reason for that and i try to run the Stored procedure in offpeak hrs.

I have not played around much with Temp tables in SQL 6.5. Pl do suggest me as to what to do....

Some details you would be interested on :

Server - SQL Server 6.5
Front End - Great Plains
Size of Tempdb - Data Space Available( It says shared with data)
database_name database_size unallocated space
------------------------------ ------------------ ------------------
tempdb 1502.00 MB -6301.82 MB

reserved data index_size unused
------------------ ------------------ ------------------ ------------------

Our Tempdb.mdf file is 11 gigs. I have tried several things to shrink this but with no luck. Does anybody have a suggestion on how I can free up that space. I have tried to re-start Sql but that didn't do anything. I thought that there was a bug, if the files got above 4 gig that sql wouldn't clear them, but I could be wrong

I thought I could detach it, and attach a new file, but makes me nervous without knowing if thatís correct.

TEMPDB In RAM?
My company uses a CRM application on SQL Server. We recently performed some upgrades of the CRM application that required us to move from SQL 6.5 to SQL 7.0. In our stored procedures we make extensive use of temporary tables. Our performance has slowed a lot since the upgrade. When we used SQL 6.5 we placed the TEMPDB in RAM to increase performance. According to Microsoft, this option is no longer available because of SQL's self-tuning ability. It would seem obvious that having the TEMPDB on disk is going to be much slower than having it in memory. I was wondering if anyone else is in the same boat, and what you did to speed up SQL Server?

Thanks for any help or suggestions,

Justin

Help With Tempdb
So i've been delegated to be a SQL Server DBA now (which I am perfectly content with), but im running into some issues and I am not sure how to proceed.

To make a long story short:

-installed a new server with SQL Server 2005 SP1. Has two databases on it.
-(2) arrays: 1st array is RAID 1 with some of the database and t-logs on it (I know..working to fix): 2nd array I just moved the tempdb.mdf file and tempdb.ldf files over this morning.

I was getting horrible I/O performance (to be expected) which prompted me to put in some more drives and move the tempdb files. This helped a bit, but now I am noticing some very funky things.

Over the last hour, i have seen my tempdb.mdf file grow from 10mb to almost 90gigs. I've been watching the performance on this machine, and the array with the tempdb is really seeing a lot of writes to it.

I am very very new to SQL server. Does anyone have some suggestions on profiiling and tracing I can do to see what is going on? Something in the Query analyzer?

I really appreciate it very much. This is new territory for me.

Thanks.

TempDB
For a variety of reasons, the C drive on our Production Server is low on disk space. When we ordered the server it came installed with SQL Server 2005 and they defaulted the System databases to the C drive. All our client dbs are on the F drive. The tempdb database gets fairly large every day and consumes a large portion of what is left of the C drive. Every evening, after work hours, I have to stop SQL Server, delete the tempdb.mdf and ldf files and restart. Is there a way to move the default location of the tempdb files to the F drive? I do not want to repartition the hard drive or uninstall and reinstall SQL Server.

Thanks in advance,

Is TempDB Used?
Hello, hopefully this is not a redundant question...

Our software uses a SQL database of it's own, and a scanner will run to collect file information on folders specified.† This will get posted to the SQL DB using ODBC calls to insert into the database.†

My question is if at any time (probablly more in general), does any inforation get posted to the TempDB before it makes it to the actual database.† If not, what is the TempDB used for?
