We had someone create an extra data file and log file for tempdb. So
we currently have two data files and two log files. Is it possible to
delete the newly created data and log files? If I just delete the
physical files, I assume they'll get created as soon as SQL Server
gets started back up. Any help would be great, since a single data
and log file for tempdb is my goal.
Thanks much.

I was in the process of creating additional TempDB.ndf files, and received an error saying they already exist. I checked the location and it was empty, nothing to see here. So I looked in sys.master_files and there are several tempdb files listed in various locations, all of which come up empty.
So the files are listed as online in sys.master_files, but they do not exist on the server. I restarted SQL services but it did not change anything.
I proposed on a new server that we separate Data Files, Log Files, tempDB, Backups, etc. onto separate LUNS on a SAN with High Speed Solid State Drives.I was told that with the new technology with solid state SAN's that it would decrease performance and that it did not work the same way as it did when you had RAID 5's etc.I thought that if things were cared out correctly by a SAN Administrator they would know how to configure for optimal performance.
View 2 Replies View RelatedI'm having an argument with our infrastructure architect who has just gone and bought lots of SSD drives to use for our tempdb data and log files, sounds great doesn't it? There is a catch though, his plan is to add the disks to the two available slots in each blade in a RAID0+1 configuration, effectively giving you one usable drive, and adding both data and log files on to one disk.
I then pointed out that SQL Server best practice is to host tempdb data and log files on two separate drive to reduce contention. The architect then basically said that because this isn't spinning disk the issue of drive, r/w contention isn't an issue I don't agree with this and wanted to get some opinions from the community, I'm still advising that two separate disks should be used but someone just went and spent £80k ($150k) on SSDs and doesn't want to back down...
I'm running this procedure which insert into table_name(id, name.....) select id, name.... from table_name. For some reason the tempdb data file grow up to 200GB. The tempdb is set to expand unrestricted by 10%. How can I prevent that from hapening? Thanks.
View 5 Replies View RelatedI am currently investigating aa high avg write time ms issue (145ms) which seems to be only occuring on the tempdb data files.I have followed the recommended setup of TEMPDB in that
1. Data files = number of physical cores
2. Data files and logfiles are on separate partitions away from the other databases.
3. Tempdb is presized and no incremental file increases look like they are happening with frequency.
We have sharepoint 2012 setup on other sql servers and with TEMPDB setup following the same guidelines, with far more Sharepoint activity on a similary specified hardware which is why its confusing.FileIO auditing on the partitions themselves shows that the FileIO is very fast on the partitions that the tempdb data file which leads me to beleive that Sharepoint may be the culprit perhaps due to excess use of tempdb with operations taking a long time to resolve.
I have a database and I see that I have a lot of TRN files behind it taking up more than 82GB disk space.I have a TRN file from Jan until today. I plan to delete every one of them until April to recover 59 GB of disk space. Would that be OK?

View 2 Replies View RelatedWe have our Maintenance routines set up to delete files older that one week, but it is not working...
...Consequently, we forget to go out and remove the files manually, thus we lose backups due to the drive being full and have to manually remove files, then backup the databases and start all over again.
Has anybody had this problem and can you tell me where to look to try and figure out what the problem is ??
Thanks in advance,

I have a backup job that has failed.
The database size is 20.6 GB and the Transaction logs are 135MB
The amount of disk space I have left is 3.65MB. Which I know is not going to work.
However on the maintenance plan it is suppose to remove files older than 1 day.
I am wondering if a job works like this:
Step 1 create backup file
Step 2 Create Transaction Log Back up
Step 3 Delete old backup file
Step 4 Delete old Transaction log back up
Which tell me I would need to have double amount of disk space to accommodate 2 20 GB backup file and 2 135MB Transaction log file.
Is this correct??
Also is there a way that I can have step 3,4 done first.

i have a maintenance plan running on my database, in which I told the wizard, on creation, to "remove files older than 4 week" and yet it doesn't seem to be doing so, as on checking this morning, diskspace was getting low, due to over 300gb of backups and trn' dating back to september.
Anyone have ny problems with maintenance plans not cleaning up when told?

I have created some backups where expiration dates or days to be
retained were not specified.
Using EM, how do I find the old backups.
Using EM, how do I delete the old backups (hoping this will
clean up the MSDB tables and physically delete the files
from disk).

Such a simple task. Not doing as it should!!
This Maintenance Cleanup Task is set to delete all BAK and TRN files it's made (in seperate maintenance plans) in given path, with the given file extension, delete files based on the age of the file at task run time. Delete files older that 4 days.
The files are now backing up for months and months. I'm not going to take care of this. I've got a computer to do this for me, every time it runs its jobs, every 4 hours and once overnight.
This is ignoring commands and refusing to do as it's told. I've checked the settings in here over and over. It's so simple - what could be wrong? I've checked the path, the file age, the extensions... The disks are getting full!
Has anyone seen anything like this?
I get the following error when I try to delete files using the FTP client in a SSIS package. This is the error I get.
Error: 0xC002918E at FTP Task, FTP Task: Unable to delete remote files using "FTP Connection Manager".

This is a unix server. I'm able to delete the files using other FTP clients but the FTP client in the SSIS package cannot delete the files. I read on many places on the interent that this is a known MS bug. Let me know if there is some sort of work around for this. I'm using SQL servewr 2005 SSIS packages to accomplish this task..

What is the best way to fix issues with your log files in TempDB when you start to see them causing error msgs?
Thansk for your time.
I was in the process of migrating a server from one physical box to another. They are identical drive setups, same OS (2003), same SQL install (2005). Our server team did a 'PlateSpin', which copies the drives from one server to another, as long as the files are not in use. I did not reinstall SQL on the new box, i let the 'PlateSpin' tool copy everything over for me. I then stopped the SQL services on the old server and new server and copied over all of the system database (.mdf & .ldf) files. As soon as i started up the services on the new server, it looked great with one exception. The TempDB was only showing one datafile. When i queried sys.master_files, it was showing me 8 TempDB files. I tried restarting the services, but i still saw the same, only 1 file. I then tried to re-add TempDB files with the same name, but it would error saying they already existed. In turn, i could add new files with different names and they showed up fine. However, on a restart, they would not show up in the properties of the TempDB.
When i queried, sys.master_files again, i now had 16 Temp db files listed in the results. I deleted all but the original single file that was recognized out of the sys.master_files table and re-added the additional 7 files with he original names, restarted the service and then they all appeared.
Hi all, I have a tempdb that consists of 8 datafiles, tempdb_data_1 totempdb_data_8, each is 8GB. Now how can I drop 7 of them and leaveonly tempdb_data_1? Can this be done? Thanks a lot.

I am running 2005 SP2 (It is the SP2 refresh as I downloaded the SP2 on 3/15/07) and I can't get the .txt maint plans to delete. The job completes successfully; however, the old .txt files are still there. I found this technote: http://support.microsoft.com/kb/938085
although I don't receive the error message in the KB. The report does have "New Component Output" as the 1st line in the report. I still don't see how deleting the 1st line of an already run job (the report) will affect a new run of the job.
Also, I checked the version of the Microsoft.SqlServer.MaintenancePlanTasks.dll and it is at 9.00.3043.00 (which is the SP2 Refresh) in KB 933508 ( http://support.microsoft.com/kb/933508 ).
I have several SQL/2005 servers and they all have this problem. Any help would be appreicated...

Documentation that supports the placement of Tempdb files on the root of a drive, i.e T: instead of T: empdb. I am positive this is not a best practice, but when challenged could not find any documentation that would support that view.
View 7 Replies View RelatedIt's been a long time since I've tried this, but I have a SQL Server that needs to be restored (including master) to a server whose drives and corresponding folders match the source server, with the exception of tempdb. When SQL Server initially starts I believe it will fail since it cannot find tempdb. I just don't recall if it fails to startup or if it starts up reporting errors and recreates tempdb in the same location as master. Does anyone recall the steps needed to point SQL Server to the new location of tempdb?

So we have new servers that are going to be installed with SQL 2012 and I'm debating the wisdom of splitting tempdb with multiple files.
I know it's a myth that performance automatically improves if you split it into a number of files based on processors, but I'm debating the wisdom of putting a file on each of my data / log file drives.
For instance, I have a server with a C: drive (OS), D: drive (Data for system DBs and install of programs - 458 GB), an F: drive for user DB data files (767 GB), and a J: drive for log files (255 GB).
Obviously no files are going on C:. I'm debating on whether or not we should even leave system DBs on the D: drive given in our current 2k8 servers, we end up with Memory.dmp files over flowing the D: drives as well as .cabs and other install / update files that tend to collect on that drive over the years.
But if we leave the system DBs on D:, I'm wondering if adding a second tempdb file to F: and a third to J: will improve query performance or not.
Have a SQL2008R2 instance on a VM where the single .mdf for the tempDb database is located on a high contention disk. I've managed to get another 60GB disk and thought it would be a good time to move the .mdf and also increase it's size and number of files.
The server has 12 cores and after a bit of reading I've decided that it would be best just to have four files for this database as the 1 file per core (-1) seems to be disputed.
-- Move the existing file to the new disk and rename it.
ALTER DATABASE tempdb MODIFY FILE (NAME='tempdev', FILENAME='E:SQLData empdb0.mdf');
-- Change the size to 1GB
ALTER DATABASE tempdb MODIFY FILE (NAME='tempdev', SIZE= 1048576KB, FILEGROWTH=5%);
-- Add three new files, all with the same size & growth
ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev1', FILENAME = N'E:SQLData empdb1.mdf' , SIZE = 1048576KB , FILEGROWTH = 5%)
ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev2', FILENAME = N'E:SQLData empdb2.mdf' , SIZE = 1048576KB , FILEGROWTH = 5%)
ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev3', FILENAME = N'E:SQLData empdb3.mdf' , SIZE = 1048576KB , FILEGROWTH = 5%)
-- Now restart the instance.
Also, what are peoples thoughts on percentage growth for tempDb? I've read that it's not recommend and yet it seems to be the norm.
My server has two 8 core processor. Should I use 8 or 16 data files for Tempdb?
View 4 Replies View RelatedI have a tempdb split into 4 files (5 if you include the log).
Autogrowth is disabled on the mdf/ndf files so that they can be used round robin (1 file per logical CPU).
Is there a way to be alerted when there is x% of free space left?
I know hwo to check the free space via t-sql but want to be able to be alerted. I could run a sql job that reports the free space and send a database mail message if under x% but wondered if there was a built in (or better) method?

Thank you very much for your kind attention.
Just found that my tempdb is always full whenever I run a query against a large database. Could please any experts here give me any advices on what is tempdb database used for and how to determine what files can be deleted from it?

I need to have an automated process to generate and send out csv data on a set schedule. Using the sp_send_dbmail routine is working great except for one small problem I am having trouble getting around.
I am specifying a query to be run and including the results as a file attachment. The customer wants a csv file with column names.
The attachment always includes a 'separator line' of dashes between the column header and the actual data. Is there any way to eliminate this line of dashes? When I use @query_result_header = 0 flag, it removes the line of dashes, but the column names are also removed as well.
I want to keep the column names, but just remove the line of dashes.
