The TEMPDB transaction log file keeps growing.The database server is new and the transaction log was presized to 1 GB on installation. After installing a number of databases, the log file grew over a day to 38GB. Issuing a manual checkpoint was the only way to free some space to allow it to be shrunk back to a usable size. The usage of the file is still going up.
I am struggling to find what process is causing the log to be used so heavily. Looking at the log reuse wait desc for tempdb returns "Nothing" and tempdb itself isn't being used very much or growing in size.
We have an issue with the Version Store growing constantly. According to sys.dm_os_performance_counters, "Version Generation rate (KB/s)" is growing, but "Version Cleanup rate (KB/s)" isn't. We use read-committed snapshot isolation
While dbcc opentran and sys.dm_exec_requests don't show any long running transactions, I wrote a query looking at sys.dm_tran_ active_snapshot_ database_transactions. This shows a number of long running transactions but, according to sys.dm_exec_sessions, they are all sleeping. The transactions that are running come and go very quickly, as I would expect.Could these sleeping transactions be responsible for preventing the version store from cleaning up?
I have a three-tier app written in C#, which takes information from a third party source (typically an array of double precision floats) and commits it to a SQL 2005 Db.
The Server then notifies the client that the information is available and the client queries the Db (through the server) in order to display it in "real-time". It all seems to work fine except that the memory usage by SQL 2005 just keeps rising. I have run a memory profiler on the server and client apps and they do not have a leak.
The test I am running has all three apps on the same machine and is reading in about 250k of data a second. It typically runs for just under two days on a machine with 2Gb RAM before falling over with System.OutOfMemoryException.
I have tried setting max memory usage but it seems to make no difference... anyone seen anything similar or know what my problem might be?
Error:- (1 row(s) affected) DBCC execution completed. If DBCC printed error messages, contact your system administrator. Msg 5042, Level 16, State 1, Line 1
The file 'tempdev1' cannot be removed because it is not empty.
Note: =>I restarted SQLServer from SSMS and then ran same commands mentioned above ,......and getting same error... => I executed above commands and restarted services...no change...
I'm looking for monitoring page file usage for SQL Server. Ultimately, I'm trying to prove that there is not a problem with a server and that it is not struggling with the workload, but someone has looked at page file usage and suggested there is a problem.
I've set up performance counters running from a separate server, but the counters relating to page file usage seem wildly inaccurate. E.g., I've got (_Total\% Usage), and (Total)\%Usage Peak), with Total Usage showing a constant value of 64, and the peak showing 92. I've also got Process (sqlservr)Page File Bytes and Page File Bytes Peak, which are showing values like 61,275,688,960 and hardly dropping below this.
If I look at Performance Monitor directly the values shown in here correlate with this, as shown in my first screenshot. However, if I look at resource monitor and look at disk activity, you can see that there is basically nothing going on (screenshot 2).
The server is more than equipped to deal with the workload, and looking at other counters for SQL there is no indication of problems, e.g. page life expectancy has a minimum value showing of 576,258, there is never less than 6GB of free RAM, SQL compilations are at a maximum of 5% of batch requests.
It is a physical server with 2x 8 core multi threaded CPUs, 64GB RAM with 58GB as the SQL server maximum. Hopefully this is enough info, but I'm happy to check anything else.
I can get a snapshot of tables in tempDB, but I would like to track which procs are causing the load in the tempDB.
I think I can sample and record objects in the tempdb, but I would like to record the proc creating the most tempDB usage, and disk read/writes associated with those procs.
The DMV's give usage in the individual DB's, but what's a good way to correlate procs in the DB's to tempdb usage?
The comapny i work for has a server running the following.
Opteron 246x2
2 Gig memory
320 Gig Sata 2 drives
Windows 2003 Standard Edition
SQL Server 2005 Express Edition. The Free one.
There are approx 10 users that connect to the server.
There are two programs which seem to use sql server. Act 7.0 and service ceo.
When the computer is rebooted its at 0% for sqlserver.exe
Than when all connect it maxes it 50% and its steady there. Seems Service ceo affects it the most.
Told by comapny need to buy full blown sql server to resolve problem. But i dont think this is the problem.
Questions: Is it common for server to be at 50% all the time with sql server running?
And if its not is there a way to reduce the sql cpu usage.
I am new to sql server and have done alot of research and fixes. Ive unsitalled and reinstalled all sql instances and done the tweaks suggested. Any fresh ideas would be great thanks.
Why does a log (.ldf) file keep growing and growing and growing? Is this related to the fact that the scheduled Maintenance keeps failing due to exclusive access problems?
Hi, my log files are growing like anything. One of my log file size is 20GB. How i have to reduce the log file size. If i run DBCC command is it come backs... Pls tell me the way how i have to find the free space and reduce logsizes. After taking backups also my log file sizes are not reducing.
I have a database of 22 gb in sql 2000, my database option is set to full recovery mode, the problem i'm having is the tran log is growing too fast, this morning it was 24 gb, more than the database size. Can anyone help how I can keep it in a managable size?
I have a DB with 1 data file, 1 log file and 1 index file. data file is 3 GB but index file is 12 GB. Index file is growing big day by day. This cause performance of DB down. What should I do to prevent index file become bigger and size of index file smaller?
My log file was 2x the size of my actual Database which is obviously too large on a DEV box. I know that my data can be easily recovered so I actually do not even want/need a log file.
After doing some investigation I found that I should turn my database into "Simple Recovery Mode" and after this I used a few scripts to truncate my log file. Things at this point looked great!
Unfortunately my log File is still growing even with this 'simple recovery mode'. So how do I stop this craziness from occurring?
I even unchecked the box 'allow autogrowth' on the database! However, I eventually get errors when creating records in the system because it complains about running out of room in the log file.
Code:
The transaction log for database 'ReportingDB' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases
I started my database in last week to user with transfer data from Sybase to sql 2000 server. Intitally log file size was few MB near to 20 MB for each co’s, within 8 days it has reached upto 300 MB still datafile size in few MB , approximately 40MB for each co’s, why log file growing in such manger, how I can manage it?
Hello, we are running Microsoft SQL 2005 Express edition (9.0.32).
Recently I just noticed that the database log file of our main database is HUGE. The database data file is only 50MB and the log file is 210GB.
Any idea what is causing this? Seems to be getting bigger with time, in the last 7 days seems to have grown by 100GB. I noticed the following settings under the database:
I am using Append to media backup option in 2000 Version. The size of backup is growing. how can I best create the maintenace plan to clear the history or clear the old files in BACKUP (.bak) file but still be able to restore point in time from same physical file. I
I have got another annoying problem. The MDF file size on one of the machines is growing really fast. We zip the mdf/ldf files every day from all the machines in the dataentry dept. On this particular machine, the mdf file size is growing by about 1GB per day. However, when the file is zipped, the zipped file size comes closer to the zipped files from the other machines.
I'm having a problem. When I use the SQL query to make a backup of the database, it worked fine. But everytime I use it, the backed-up file's size kept growing in size. Say I have the file, test.bak whose filesize is 450 MB then I run a new backup to overwrite the existing test.bak file, it just end up as 900 MB. If I run it again, it become 1350 MB and so on.
I have an 19 gig database that somehow has a 100gig log file. The DB MUST BE in full recovery mode, I backup the transaction logs EVERY hour and shrink nightly. but for some reason my logfile WILL NOT SHRINK.
HELP,
I've used both the DBCC Shrinkfile (xxxxxx) and DBCC ShrinkDatabase (xxxxx) and these don't seem to work. I Have No current backup, I have Not capacity for addtional 100 gig worth of backup drive or off-site tape.
Hi there,I have a data manipulation process written in a Nested Stored procedurethat have four levels deeper. When I run these individual proceduresindividually they all seems to be fine. Where as when I run them alltogether as Nested proces (calling one in another as sub-procedures) Logfile is growing pretty bad like 25 to 30GB.. and finally getting kickedafter running disk space. This process is running around 3hrs on a SQLserever Standard Box having dual processer and 2gb ram.This procedures have bunch of bulk updates and at least one cursor ineacch procedure that gets looped through.I was wondering if anybody experienced this situation or have any clueas to why is this happening and how to resolve this?I am in a pretty bad shape to deliver this product and in need of urgenthelp.Any ideas would be greatly appreciated..Thanks in advance*** Sent via Developersdex http://www.developersdex.com ***
In SQL Server 7.0 sp1 (NT 4.0 sp5) I have a server that has a tempdb database that continues to grow. This server contains the database for SMS. Over the weekend, the tempdb had grown so much that it filled up the drive (37GB). I have shrunk it down to a much more reasonable size and put a limit on how large it can grow. I'm noticing today that it is beginning to grow again. Is there a way I can look at the information that is in tempdb right now? I have to think that there are open transactions for some reason that can't commit. I know that tempdb gets cleared out when SQL Server is restarted, but I can't be restarting it this often.
On Microsoft's website, I did find an article about SMS Y2K queries using large amounts of Tempdb and failing to complete. The solution they have in this article Q234912 is to install SMS sp1 which is already installed.
I haven't been able to find any other useful information yet on this problem. I would appreciate any help you can offer.
Hi there, My tempdb is growing from its normal size of 800MB to 2GB. I've been shrinking it using dbcc shinkfile/ dbcc shrinkdatabase. Everytime I run the command, immediately it says that the execution is completed and successful. However, when I checked the disk space, it remained the same, as though no shrinking is done. Can anyone help? Also, it was published that restarting the SQL server can re-create tempdb from scratch. I've tried it too, the tempdb just wont go back to its normal allocation. My constraint is limited disk space, would appreciate any good samaritan to give me some help here. Thanks in advance!
I want to truncate my sharepoint config database and WSS_Logging database logs the size of sharepoint_config database is growing at a pace of ~10GB every week. I have scheduled a weekly full backup. Current .ldf file size is 113GB.
I am using SQL server 2012 with Always On High Availability feature. I am not able to set the recovery mode from Full to Simple as it gives me message that mirroring is running on both server.
In my case to reduce the log file what I need to do.
I notice this morning that my tempdb grows very fast. I have 26GB in my hardrive and all the space occupied by tempdb and finaly the qeury got failed due to 0 space in hardrive and there is no space to grow tempdb. The select query supposed to bring about 40000 rows. I ran this same query in different server that is not growing even 1 mb. I checked the tempdb option the Trunc log on checkpoint is true.
Why this problem happening ?. I have just dbo permission to access all the database. Do you have any advice regarding this?. Thanks, Ravi
I have a db application that has been running fine for months. Volumes have been gradually increasing and one day the system locked up.
A stored proc that typically ran in 3 or 4 minutes never returned. The tempdb kept expanding to fill available disk space (100GB). This was the offending statement inside the stored proc:
INSERT INTO cpp (CPPDate,MerchantLink,ReportNumber,FromDate,ToDate ,TransThreshold,DayThreshold,CPPType) SELECT S.CPPDate,S.MerchantLink,s.ReportNumber, s.FromDate,s.ToDate, S.OccurThresh,s.DaysThresh,'D' FROM #stuff S, Trans T with (nolock), Supplier P with (nolock) where T.MerchantNumber in (SELECT MerchantNumber FROM Merchant WHERE MerchantLink = s.MerchantLink) AND T.TranDate >= S.FromDate AND T.TranDate <= S.ToDate AND T.LoadDate <= @ReportDate2 AND (T.SupplierNumber = P.SupplierNumber AND T.IncludeInCpp = 'Y' AND P.CountryNumber IN (SELECT CountryNumber FROM REPORTCOMBO WHERE ReportNumber = s.ReportNumber)) GROUP BY CPPDate,Merchantlink,ReportNumber, FromDate,ToDate, OccurThresh, DaysThresh HAVING COUNT(DISTINCT T.AccountNumber) >= OccurThresh
I realize that a "group by" uses the tempdb, but can't figure out why it would go away rather than returning an error.
I have a workaround in place now. I split this big query into several steps using a cursor. (slower and clumsier, but it works) Statistics are updated daily, i have tried defragging, and reindexing with no success.
Any thoughts would be appreciated. If you need any more details, please let me know.
for the first time in my long SQL DBA live I see such a behaviours. My tempdb database is growing every damn second since a this morning. Now it reached 30Gb, the log file is empty (217 Mb).
We use SQL 2000 Ent on Win 2000 Advance Server. Running Siebel Call Center (7.5 ver) with about 300 users.
Some users time to time obtain and hold a huge amount Exclusive locks on the tempdb extents
We are having problems with our SQL server 2000. The problem is that on a daily basis we run out of disk space and I always have to run shrinkdatabase on tempdb. Today we started with 160GB of free space and by the end of the day it was gone!
Yes we do have many jobs running on our SQL server pulling data in from many sources. But I dont know how to find out which job is causing this problem. I have a suspicion that it could be a job that runs hourly that pulls data from Oracle (approximately 10000 rows each time), but that job has been active since the 28th August 2007. We only started running out of space in the past 5 days. Any suggestions would be appreciated as to what is causing this or how to diagnose the problem.
I need to write a process to get file size in kb and record count in a file. I was planning on writing a c# console app that takes the file path and name as a param however should i use a CLR?
I cant put a script in the ssis when it's bringing the file down because it has been deemed that we only use ssis for file consumption.
I need find out the number of columns in flat file before i process that particular file.I have file name in @filename variable and file path is @filepath variable.But do not not that how i will check the column name in before i will process that file.
@filePath = C:DatabaseSourceFilesCAHCVSSourceFiles And i am using for each loop container to read the file one by one and put the file name in @filename variable.and my file name like
Now what i have to do is i need to make sure that ID,Name,City,County,Phone is there in flat file.if it is not there then i have to send mail to client saying that file is not valid.I need to also calculate the size of flat file.
I have a filetable that contains a binary file. I need to do a selective read of the file stored in the file table. I can write a C# CLR function that will open the file, read n bytes the from a starting byte. Or I can write a SQL statement that reads the stream in the filetable into a VARBINARY variable using SUBSTRING beginning at the starting byte (offset from 1) for the same n bytes.
Both give me the same result. However, the SQL statement takes considerably longer to read. I know there is overhead in reading through SQL (interpreted language), but the difference in performance is substantial, and I can only attribute this performance degradation if SQL first tries to "load" the entire stream before it identifies the portion of the stream that it needs to read beginning at the starting byte offset.
I wonder if this is the case or if there is another option to read a stream from a filetable directly through SQL queries that is more efficient.
