In on of the server tempdb is not releasing the reserved space after completion of data loads,as of now 99% of free space available in data file,we tried to shrink the datafile ,and space has not been released.
View 7 Repliestoday I've put in production a big database accessed by 200 concurrent users, this database has READ_COMMITTED_SNAPHOT set to ON.I know that RCSI set to ON is very aggressive on tempDB so I'm monitoring it.I've noticed that the Transaction log space usage (%) on TempDB is slowly but ever increasing, I mean in the last 24 hours I've started from a 99% space free, now we are 37% space free...is it normal? TempDB log is 35GB in size.
View 6 Replies View RelatedI have scenario where I have process that loades data into SQL server 2012 database by doing some manipulation on data like sorting , aggregation, etc. Once this process is completed it's not free up the Tempdb space. If I restart the database, then it does.
is there any way (apart from shirking) to release space for Tempdb, like writing some post SQL queries to delete/ truncate the data and logs from temp db?
We have deleted 120GB of data but space did not released even after 2 days. Is there any reason for this? tell me how exactly it releases the space after truncating a 120GB table?
View 8 Replies View RelatedDear Friends,I'm running a SQL 2005 database. Lately (in the last 4 months) my database size has grown exponentially and now totals 2.5 gig (it used to be about 100mb). When I run sp_spaceused i get the following info:
Reserved Space 2522MB
Data 450MB
Indexes 215MB
Unused 1856MB
<!--[if !supportLineBreakNewLine]-->
The unused space is reserved by my two largest tables, one being 542mb (which is a log I create and the size seems fine for the amount of data) reserving 1033mb and the other being 121mb (which is another log and also seems fine) reserving most of the rest.
I have tried running DBCC SHRINKFILE and DBCC CLEANTABLE commands on a backup copy of the database and cannot seem to free the unused space.
I have also tried copying the database in an attempt to reduce the unused reserved space and have tried creating a new database and importing the tables with no luck
Any help would be greatly appreciated, noting that I'm honestly not that technical and would probably need step by step instructions, but if you only have time to point me in the right direction that would also be of great help!

Hey guys,
I have a table which has 6 text columns (tblA).. I no longer require 1 of those text columns and want to reclaim the space that it is currently taking up..
Is the only way to BCP out all the data (except the 1 column i no longer require) drop the column and BCP the data back into the table?
What will the net result be if I limit the tempdb size, and it grows to it's limit? Will it crash my server? Will it shutdown SQL? I will most likely be moving it to another drive, but until then I can't have it consuming my entire drive like it did 2 days ago! Please Advise. - Rob
View 5 Replies View RelatedHi,
I'm trying to add space to tempdb. I created a new device for 100megs and then I double clicked on tempdb db and then clicked on 'Expand'. I selected this new device in the data device - pull down and then did a 'Expand now'. After it successfully completed I went back and did a recalculate to find that the log space on tempdb has been increased and not the data space. I tried this twice with the same results.
Could anyone please tell me what's happening and how I can increase the data space on tempdb.
Thanks in advance,

This database is running on SQL sever 6.5.
We are running an home-created stored procedure that includes several rounds of dropping and recreating indexes in a few tables, i.e., after dropping indexes, the tables are truncated, then a lot of records will be inserted into the table, and the indexes are recreated.
we are getting the following error in turns:
1. ODBC error: Microsoft] ODBC SQL Server Driver] SQL Server]Can't
allocate space for object '-841' in database 'tempdb' because the
'system' segment is full. If you ran out of space in Syslogs,
dump the transaction log. Otherwise, use ALTER DATABASE...
We then used EM to expand the tempdb, when reran the procedure, we got the following message:
2. ODBC error: Microsoft] ODBC SQL Server Driver] SQL Server] Cannot
drop the index 'dbo.ItemBalamce_CCB_Id',because it doesn't exist in the
system catalogs.
However, when I check the mentioned index, it is certainly there.
How could this happen?
After several rounds of running theis procedure, these two error messages appeared to occur alternatively.
If you have an answer or suggestion, please let me know ASAP.
Many thanks.
I received an alert from our alerting system that log space for tempdb is used over 60%.
My question is what options do I have to troubleshoot and fix it? If it would be a regular user database, I would check for log_reuse_wait_desc in sys.databases, run another log backup, and maybe some other things. But what I can do with tempdb?
Hi All,
Sql Server 7
My tempdb is eating 1.27 gb of space of my d dive, and now only 10 mb is left in d drive . for this i stoped and started sqlserver but it didnt release much of space.Pls let me know is there any other way so that i can release some space from my tempdb.
Waiting for reply

what is the best way to make free space in tempdb?
View 5 Replies View RelatedI am getting an error while running SSIS package:
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Could not allocate space for object 'dbo.SORT temporary run storage: '...' in database 'tempdb' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup."
The destination is sql 2000. The package does not create any large temp tables.
apart from setting MaxInsertCommitSize property on the destination in Data Flow, is there anything else I could do?
Where do I find this MaxInsertCommitSize option?
Hi,
I am using SQL2005 SP1 and I have a 4Gb Tempdb (datafile) with virtually nothing in it.
I am unable to release the free space to the operating system. I have used dbcc shrinkfile...truncateonly but this has had no effect.
There is no error message and there are no open transactions, I have attempted to drop the data file by transferring to a new file but I can't because it the primary file...
Any idea would be very helpful!!
Cheers.
does anyone know if tempdb can be physically moved to a different partition on a disk drive on SQL Server 7.0? Since it can't be backed up I'm hesitant to use the sp_detach/sp_attach procedure because I don't want to crash it. If nothing else is available, I can attempt moving it this way at the end of the day and then just reboot to get tempdb back up again if the server fails, but I'd really appreciate a suggestion from someone who has more know-how than I do about system table operations. Thanks again

In Sql Server 2005 sys.dm_db_task_space_usage is great for tracking down temdb space issues.
I have tempdb space issues in sql server 2000, how do i get the same info in SS2000 ? IE: What spid is using the most tempdb space ?
Thanx
We have an App server where Microsoft reporting services (report Builder 2005) is hosted and the backend Database server which is used by the reporting services.
The clients create very complex reports (usually towards month end) and run against the database causing the tempdb grow expenentially, leading to perfromance degradation and worst case space issues.Our only solution is to reboot the server.
There should be many systems which sould be having similar scenarios like mine. How to handle the scenario.usually in my database tempdb should be below 15GB... but it had grown to 60GB in some instances.
I try to find some feedback regarding setting the TempDB files on a RAM disk.Specifically I am looking for "production results" that could show the difference/benefit of such an usage.The tests on physical server and VM I already made have shown a boost in overall SQL Server 2012 performance on SQL Server instances housing data for SharePoint 2013 and Dynamics AX 2012 R2.Graphic below show differences between 5 different configuration on the same physical server:
- Physical HD: Server with local HD
- Physical SANEX1PRD: Server with TempDB files stored on a low-end SAN
- Physical SAN1: Server with TempDB files stored on a high-end SAN (around 100000 IOps)
- Physical SAN1 Jumbo: same setup with Jumbo Frame activated on NIC and DB engine
- Physical RAMdrive: with TempDB files stored on a 16 GB soft RAM drive within OS memory
Results were really impressive for the DB engine housing Dynamics AX data. My colleagues from the SharePoint team told me it also boosted a bit overall SharePoint performances but they did not have any baseline comparison to show.If you have some feedback, results, links, whatever I am interested.Indeed before setting this to all our SQL Server 2012 instances I y rather collect some *real world* feedback.
Application is throwing errors.Is there anyway to fix this with out restarting the server on a newly migrated system?

I have a query that is using up the whole TempDB (50GB) and still failing because the disk runs out of space.
The script has SELECT FROM SELECT FROM SELECT etc. and in each select it also seems to have joins.
I can also see a few UNION and UNION ALLs.
Is this normal for one query to use up that much space?
If I wanted to make this better where would I start?
I 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.

View 1 Replies View RelatedIn 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.
Could a simple update statement on a user database ever caused space usage in tempdb? Assuming the update statement fires no triggers and not using any temp tables?
IE:
User DatabaseA
Update TableX
Set col1 = X
Reason I ask is tempdb filled up and the only thing I could see running at that time was the update statement.
I have used Extented event to monitor the occurances of TempDB contention on Production server . I found there are several entried logged in in 30 mints .Now I am trying to determin if Tempdb contention on PFS, GAM or SGAM page then I will decide if I need to increase the number of TempDB data files on Production server . Currently , There are 8 TempDB Data files configured on its separate Disks .There are Page_IDs I found in the extented events for Tempdb files -
Page_ID =1 for PFS page
Page_ID = 2 for GAM page
Page_ID =3 for SGAM page
but I found the Below Page_IDs and I know there is a formula that you can use to identify if page is PFS,GAM or SGAM ? How should I use this formula and what should I look for to determine if page is PFS,GAM or SGAM ? Is there any threshold value for the duration of TempDB contention occured ?
We have SQL Server 2012 EE SP2 server that is getting hit by reports that time-to-time use up to 300GB of tempdb.
It's happening because our clients can use 'bad' parameters for some reports.
Is there a way to autokill sessions that overuse tempdb (for example, if a session uses more than 15Gb in tempdb)?
Killing can happen immediately or after regular check (5 min for example).

We have a database with about 500 GB of free disk space on data file and the database is being set to read only mode for the fore-see-able future. We would like to release this unused disk space. We know that we could shrink the data file and then work on re-indexing to remove fragmentation.we wanted to check if some other method like backup and restore of the database could free up unused disk space in the data file. if someone was able to release unused disk space on data file by implementing a backup and restore.
I have many large tables with millions of records in a SQL Server database. They all use an Identity column which is the clustered index. We haven't been deleting any records until recently because disk space is now becoming a problem.
Assuming I delete a lot of old records, I'm thinking that the freed up space in the data pages won't be reused. New records will be added at the end of the table because of the Identity column being the clustered index. So the table will keep getting bigger even though there is lots of free space.
Assuming I'm right, then how do I recapture this unused space? Is an alter table rebuild the best way? Or rebuilding the clustered index?

2 of the secondary data files had its autogrowth enabled to unrestricted with 200MB and 3 of the data files including primary had its Autogowth turned OFF. Application use is complaining that there is no internal freespace on the DB.
What fails to understand us is that when the Auto growth was already TURNED OFF on 3 data files ( 1 primary and 2 secondary ) still why was the application trying to increase the space on the .mdf and .ndf files; as well when the Autogrowth is TURNED ON on 2 of the secondary data files, why was the DB not able to expand these file groups when the autogrowth is already turned off on 3 of its other files.
What more data i need to ensure i submit an analysis to this.
In my environment, there is maintenance plan configured on one of the server and while running DBCC checkdb on a database of size around 200GB, log file usage of tempdb is increasing and causing the maintenance job to fail.
What can I do to make the maintenance job run successfully, size of the tempdb database is only 50GB and recovery model is set to simple. It cannot be increased as the mount point on which it is residing is 50GB.
