TempDb Filling Up!
Jan 14, 2000MS SQL Enterprise Server, SP5, running under version 6.5.
I have recently been having a problem with the TempDb database
filling up. I originally started the database at 250 Mb but
recently expanded it to 500 Mb.
My last check of the activity on the server during an event
such as this produced the following information.
- Approx. 300 connections to primarily 2 databases.
- 4 active connections:
Connection 1 -SELECT on database 1 with 13,000 records
and a record size of approx. 300 bytes.
Connection 2 -SELECT on database 1 with 13,000 records
and a record size of approx. 300 bytes.
Connection 3 -SELECT on database 2 with 550 records
and a record size of approx. 100 bytes.
Connection 4 -Replication subscriber set at 100 transactions.
My questions are:
1. What processes may cause the TempDb database to fill up?
2. What processes prevent the database from purging?
Any information would be greatly appreciated.

TEMPDB Filling Up
May 4, 1999Recently, we converted an Access database to SQL server 6.5. One of the processes that runs against the server is
missing a commit causing temporary stored procedures to fill up TEMPDB in the sysobjects table. The only way to
clear up TEMPDB is to stop and start SQL server when the database fills up. I wrote a quick and dirty stored
procedure to delete the affending rows out of the tempdb..sysobjects table, however, the database still registers as
full after the deletes.
Question:
does anyone know of a process/DBCC I can run against the tempdb..sysobjects table to regain the space in TEMPDB
without having to stop and restart SQL Server? I need a temporary solution while the programmer is debugging the
affending code.
Thanks!

Bad VB Query Filling Up Tempdb
Oct 2, 2000I have complex VB code that loads millions of records into a SQL 7 database. I see my tempdb slowly growing until system runs out of disk space.
What are typical programming bugs that would cause tempdb to fill up,
and how can I identify the offending statements through profiler?
Any help greatly appreciated!
Tempdb Transaction Log Filling Up
Aug 2, 2001We have a stored procedure that uses temp tables and must gather a lot of data. When we stress test this stored procedure, the tempdb transaction log fills up.
We tried using "Select Into" for our tables. That caused us not to write to the transaction log but it caused problems because it locked up sysobjects.
Is there some other way not to write to the transaction log?
Tempdb Filling Up - Mass Deletes
Dec 13, 2007Hi,
I've been having problems with my tempdb filling up, and causing all databases on the server to stop functioning properly. I've been removing alot of data lately (millions of rows), and I think this is the reason why my tempdb log is going thru an unusual load.
Whats the best way to make sure the tempdb doesnt fill up causing me major problems? I had temporarily turned off backups while I was having a new HD put in. Am I right in thinking that when a DB is backed up, the tempdb log is reduced in size? Should maintaining a daily backup solution help keep things under control ?
Thanks very much for any tips!

Drive Filling Up / Moving Data Files?
Sep 29, 2015I have a database [CarlosDB] that currently has it's .MDF on E: and I need to move the x2 .NDF data files off C: to E:data using a single T-SQL statement:
Code:
database_id file_id db_name disk_path status size read_only
----------- ----------- --------------------------------------------------------------------------------------------------------------------------------
7 1 CarlosDB E:dataCarlosDB.mdf ONLINE 384 0
7 2 CarlosDB_log L:logsCarlosDB_log.ldf ONLINE 128 0
7 3 CarlosDB_2 C:sqlCarlosDB_2.ndf ONLINE 128 0
7 4 CarlosDB_3 C:sqlCarlosDB_3.ndf ONLINE 128 0
(4 row(s) affected)
Looking at the file configuration above, what would be the most logical way as a DBA / SQL Server 2014 Std to move the NDF files to live w/ the MDF file using:
Code:
EXEC master.dbo.xp_cmdshell 'copy c:sqlCarlosDB_2.ndf e:dataCarlosDB_2/ndf'...
but cleanly using a single T-SQL statement? properly formatting a single T-SQL query to use the xp_cmdshell system stored procedure.
SQL Server Admin 2014 :: Separate Data Files / Log Files / TempDB / Backups
Jan 9, 2015I 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.

Nov 25, 2013I 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.
How To Drop One Of The Tempdb Files

Mar 3, 2015I'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...
TempDB Files On Root Of Drive
Sep 15, 2015Documentation 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.

Nov 22, 2005It'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?

SQL 2012 :: Splitting TempDB With Multiple Files?
May 21, 2015So 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.
Deleting Extra Tempdb Log And Data Files
Jul 20, 2005We had someone create an extra data file and log file for tempdb. Sowe currently have two data files and two log files. Is it possible todelete the newly created data and log files? If I just delete thephysical files, I assume they'll get created as soon as SQL Servergets started back up. Any help would be great, since a single dataand log file for tempdb is my goal.Thanks much.sean
View 3 Replies View RelatedTempDb - Moving / Adding Files And Resizing
Oct 23, 2015Have 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.

Aug 13, 2014I 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?
I also have SQL Sentry.

Feb 23, 2015I 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 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.

View 5 Replies View RelatedSQL 2012 :: TEMPDB High Avg Write Wait Time On Data Files
Apr 15, 2014I 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.
Tempdb Is Skipped. You Cannot Run A Query That Requires Tempdb
Jul 14, 2004Has 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!

How Can I Keep The Log From Filling Up?
Mar 21, 2008I have a ton of data to load into a SQL 2005 database.
I just loaded a bunch of data for a number of tables using bcp, and the last table that my script loaded was an 8 million row table. The next table was a 12 million row table, and about 1 million rows into the bcp'ing a log full error was incurred. I have the batch size set to 10000 for all bcp commnads.
Here is the bcp command that failed:
"C:Program FilesMicrosoft SQL Server80ToolsBinncp" billing_data_repository..mtr_rdng_hrly_arc_t in mtr_rdng_hrly_arc_t.dat -c
-b10000 -Sxxxx -T
Here is the last part of the output from the bcp command:
...
10000 rows sent to SQL Server. Total sent: 970000
10000 rows sent to SQL Server. Total sent: 980000
10000 rows sent to SQL Server. Total sent: 990000
SQLState = 37000, NativeError = 9002
Error = [Microsoft][ODBC SQL Server Driver][SQL Server]The transaction log for database 'billing_data_repository' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases
BCP copy in failed
I thought that a commit was issued after every 10000 rows and that this would keep the log from filling up.
The log_reuse_wait_desc column in sys.databases is set to 'LOG_BACKUP' for the database being used.
Does a checkpoint need to be done more often?
Besides breaking up the 12 million row data file into something more manageable, does anyone have a solution?
How can I continue to use my same loading script, and keep the log from filling up?
Thank you.
Help Filling Dataset
Feb 27, 2007I have a class that works fine using the SQLDataReader but when I try and duplicate the process using a Dataset instead of a SQLDataReader it returnsa a null value.
This is the code for the Method to return a datareader
publicSqlDataReader GetOrgID()
{
Singleton s1 = Singleton.Instance();
Guid uuid;
uuid = new Guid(s1.User_id);
SqlConnection con = new SqlConnection(conString);
string selectString = "Select OrgID From aspnet_OrgNames Where UserID = @UserID";
SqlCommand cmd = new SqlCommand(selectString, con);
cmd.Parameters.Add("@UserID", SqlDbType.UniqueIdentifier, 16).Value = uuid;
con.Open();
SqlDataReader dtr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
return dtr;
This is the code trying to accomplish the same thing with a Dataset instead.
public DataSet organID(DataSet dataset)
{
Singleton s1 = Singleton.Instance();
Guid uuid;
uuid = new Guid(s1.User_id);
string queryString = "Select OrgID From aspnet_OrgNames Where UserID = @UserID";
SqlConnection con = new SqlConnection(conString);
SqlCommand cmd = new SqlCommand(queryString, con);
cmd.Parameters.Add("@UserID", SqlDbType.UniqueIdentifier, 16).Value = uuid;
SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = cmd;
adapter.Fill(dataset);
return dataset;
}
Assume that the conString is set to a valid connection string. The Singlton passes the userid in from some code in the code behind page ...this functionality works as well.
So assume that the Guid is a valid entry..I should return a valid dataset but its null.
Additionally if I change the sql query to just be Select * From aspnet_OrgNames I still get a null value...I am assuming I am doing something wrong trying to fill the dataset.
Any help would be appreciated.

Delete Statements Without Log Filling Up
Aug 13, 2002I have a database that I am splitting the data using odd account numbers and even account numbers. The odd acct numbers in one database and the even in the other database.
This database is very large. The problem is when I run the delete statements
it is going to fill up the log files. Can I turn on the "Simple" mode on the database while I am deleteing the data. Will this cause a problem? Then can I turn back on the 'Full' mode when I have finished?
Has anyone ever done this and so how did it work. Or better yet is it possible?
Thanks,

Gap Filling In A Time Series
Feb 26, 2007Hello,
I am new to SQL Server and learning lots very quickly! I am experienced at building databases in Access and using VBA in Access and Excel.
I have a time series of 1440 records that may have some gaps in it. I need to check the time series for gaps and then fill these or reject the time series.
The criteria for accepting and rejecting is a user defined number of time steps from 1 to 10. For example, if the user sets the maximum gap as 5 time steps and a gap has 5 or less then I simply want to lineraly interpolate betwen the two timesteps bounding the gap. If the gap is 6 time steps then I will reject the timeseries.
I have searched the BOL and MSDN for SQL Server and think there must be a solution using the PredictTimeSeries in DMX, but not quite sure if I can do this. I may be better off simply passing through the time series as a recordset and processing as I would have done in Access...(I am reluctant to do this as I have of the order 100 * 5 * 365 time series and growng by 100 each day and fear it will take quite some time...)
Can anyone help me by pointing me in the right direction please?
Unless there is a way of using PredictTimeSeries on its own, I think the solution is:
Identify if a record is the a valid one or part of a gap (ie missing values).
Identify the longest gap and reject or process data on this value.
Identify if a record preceedes or succeeds a gap.
For each gap fill it using a linear interpolation.
Thanks,
Alan.
