Master.sys.master_files WHERE Database_id = 2 &&<&&> Tempdb.sys.database_files
Oct 30, 2007
We had an issue last night where tempdb ran out of space on one of our servers. Upon investigation I found that SSMS was reporting only one data file assigned to tempdb. I knew this couldn't be the case and dove into the system tables to figure out what is going on. I found what appears to be data corruption. There are a number of file records that appear in the master.sys.master_database_files that do not appear in the sys.database_files table in tempdb.
I tried to add files that it showed already existed and they of course errored out. I restarted SQL Server to get tempdb rebuilt and that did not work either.
Has anyone else ever ran into this? What was the resolution?
Here are some queries to demonstrate what I am seeing. Terrible formatting I know, but I don't know of a better way.

I had a procedure that created a filegroup and file, did some other work and then (theoretically) renamed the filegroup and file. Well, the DB got locked up the last time I tried to run it and the rollback was only partly successful. I now have a file with one name in master_files and another name in database_files. Is there a spiffy way of fixing this? I'm thinking all I need to do is (re)rename the file.
[Edit]
Some more examinaion shows that this discrepancy only appears on the mirrored server, not the principal.
I am truncating Transactionlog€¦ following the steps mentioned in MSKB.. what is the problem?
Use master Go
Backup log xxx with truncate_only go Dbcc shrinkfile(xxx_Log) Go
Msg 8985, Level 16, State 1, Line 1 Could not locate file 'xxx_Log' for database 'master' in sys.database_files. The file either does not exist, or was dropped.
I have a install of SQL 2005 that is about 5 months old. The tempdb.mdf and master.mdf files have ballooned to a huge size almost filling my hard drive. How do I reset them to a reasonable size?
When SQLserver2K was installed it placed master, model, msdb, tempdb data files in the installation location (i.e. C:Program Files....). This puts pressure on the C: drive, which also holds the page/swapfile. I want to move at least the tempdb location to the new 'Default data directory' and log directory we set after installation (i.e. E:MSSQLData).
How do I get tempdb to relocate to E: given that it gets recreated each time SQLserver starts?
I am interested to hear if people think it would be a good idea to movethe Master & TempDB to a different HD.Here is my DB Server's set up:1. Processor: (1) AMD XP 28002. 1st HD (IDE 0) is the system & boot drive3. (3) SCSI HD make up a hardware RAID level 0 (striped withoutparity)solution - these striped drives are just for my working DBs4. (1) SCSI HD that's not doing anything.I want to put the Master & TempDB on the SCSI HD that's not doinganything. Would that be the best place for it for maximum performance orshould I put in the striped array. I am leaning more towards putting onthe SCSI HD that's not doing anything. What do you all think?Ed*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
I€™ve had a SQL 2000 server restored (using Veritas 9.1) to another server also running SQL 2000. I now have a collation problem.
When trying to add users to a database, I receive a "Error 446: Cannot resolve collation conflict for equal to operation" message.
I noted that tempdb and user tables collation don€™t match - so I was going to change the user tables. However, the master collation doesnt match tempdb, model or msdb.
Server is set to SQL_Latin1_General_CP1_CI_AS Master - SQL_Latin1_General_CP1_CI_AS tempdb, model, msdb - Latin1_General_CI_AS
I was under the impression that when tempdb was recreated it inherited the master database's collation? This doesn€™t seem to be happening.
Since,You cannot mirror the master, msdb, tempdb, or model databases.What will happen if i create new login,change existing security profile and new jobs,change of existing job on princicpal db. how these will be mirrored to other server and in case failover, how it will treat.
"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! - Mike
Step 1. First I am filtering the Sales Order information and inserting it in my Sales Orders table. Step 2.Then I am filtering the details from the sales Order and inserting them in the respective table.
My Problem is that the Sales Order File does not contain the Sales Order key (ID), this is generated by the SQL Server. How can get it in order to use it in the second step? I need it because it is a foreign key in the details table.
I'm new to SQL and need help with a query. Not sure if this is the right place.
I have 2 tables, one MASTER and one DETAIL.
The MASTER table has a masterID, name and the DETAIL table has a detailID, masterID, and value columns.
I want to return a populated MASTER table with entries based on the DETAIL.value.
SELECT MASTER.* FROM MASTER WHERE DETAIL.value > 3
This is a simplified version of my problem. I can't figure out how to set the relationship between MASTER.masterID and DETAIL.masterID. If I do an INNER JOIN, the number of results are based on the number of DETAIL entries. I only want one entry per MASTER entry.
We already integrated different client data to MDS with MS Excel plugin, now we want to push back updated or new added record to source database. is it possible do using MDS? Do we have any background sync process to which automatically sync data to and from subscriber and MDS?
THis is sql server 6.5 question. I have tempdb data device size default 2 MB, which has completely filled up. I am trying to expand data device to it. I created new device tempdb_data_ext (250 MB) and tried to expand tempdb data device. But everytime I do it, it ends up adding space to tempdb log device. How can I expand tempdb data device?
Hi, How can I control the growth of tempdb in SQl server.It's growing like anything. CAn I create some alerts or jobs and what those alerts/job are supposed to do? All help appreciated. Jai
Hello! This is error message I discovered in NT even viewer: c:MSSQL7DATATEMPDB.MDF: Operating system error 112(There is not enough space on the disk.) encountered.
In SQL Server error log the errors are: Error: 1101, Severity: 17, State: 10
Could not allocate new page for database 'TEMPDB'. There are no more pages available in filegroup DEFAULT. Space can be created by dropping objects, adding additional files, or allowing file growth..
Currently tempdb rezides on C drive and it's almost out of space. What should I do? Detach tempdb and then move to different drive? What's the procedure?
TEMPDB in one of our production servers does not clear up so every three to four weeks I have to restart NT. Nothing like this happens on any of the other three servers. Does anybody know where I should look at to correct the problem. I sure would appreciate it. Thanks Shashu
I have never done this before and thought I would ask. Is it possible to detach the tempdb database, move it to another drive or partition, and then re-attach it? What would be the downside or side-affects to doing such a thing?
Error : 933, Severity: 22, State: 1 Logical page 258 of the log encountered while retrieving highest timestamp in database 'tempdb' is not the last page of the log and we are not currently recovering that database.
I use sqlserver -T4022 to start my SQL Server since it will not start with out it. When I start sqlserver without the option, it tells me that
Error : 615, Severity: 21, State: 1 Unable to find database table id = 2, name = 'tempdb'.
I need to move tempdb to another drive,also increase the size.Largest database is 15GB.Can anyone suggest the size and also the exact commands to move.Do I need to backup the databases before I do this task?If SP1 is not installed,will it be o.k for me for this tempdb problem.If we have a larger tempdb like 4GB,will it effect anything?...Urgent!!
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.
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 that’s correct.
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?
I am trying to get some information about tempdb database. I've tried BOL but I couldn't find a whole lot of info. I am trying to find out what size should tempdb be to not to cause problems. Also, I am trying to shrink tempdb by using shrink database option in EM, but it only shrinks the tempdb transaction log not the datafile, and I don't know why it is happening.
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.
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.
