Database MDF is 27806 MB and I tried to shrink but unable to shrink. It is production server.I do not want Restart sql server.There is no open transaction.
today 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.
I was able to find a few posts on this topic, but none of them quiteseemed to fit the situation, so I'm hoping that someone else might beable to help me here.I have a client who is using SQL 2005 (sorry, don't have the exactbuild with me). They run a weekly process which causes TempDB to growto over 100GB before it fails due to a full disk. Once it's grown tothat size we can't seem to shrink it again short of restarting theserver.The database is set to Simple recovery mode and I believe that it isset to auto shrink.Here are some things that found out/tried:DBCC SHRINKFILE (tempdev, 50000) does nothing.DBCC OPENTRAN returns no transactions.If I look in TempDB for any temporary tables, I get a couple dozen.They all have zero rows in them though. I didn't think to look at thecolumns that they contain, but maybe that will give me an indicationof their use. I used SELECT OBJECT_NAME(id), rowcnt FROMtempdb..sysindexes WHERE OBJECT_NAME(id) LIKE '#%'sp_spaceused shows that almost none of the space is actually beingused.I've looked for reindexing operations in their code and didn't seeany, but there's quite a bit of code there. While there are someoperations against some very large tables, I didn't see any obviouscartesian products or sorts either. Again though, there's a lot ofcode and I haven't profiled much of it.My plan right now is to reboot, set up a trace to track both filegrowths and SQL statements and then see if I can find whichstatement(s) are causing the TempDB to grow to be so large. Anysuggestions on additional things to track? Even given this though, Idon't know if that will help me with the shrinking issue, except topossibly prevent it from being necessary in the future.Any advice or suggestions welcome. Please let me know if I've left outany important information. I always seem to forget at least oneobviously important bit of information. :-)Thanks!-Tom.
We're running our database on SQL Server 7 and we've setup the tempdb to grow automatically.Gradually,it has grown upto 11390 MB and the used space is only 14 MB.It's not shrinking when we used the shrinkdb option.We cannot move the tempdb to RAM as it's very big.Can anyone help us in this...
How do you shrink the tempdb in SQL Server 7 after you allocated a large space to it but later realized you allocated too much.... I need to reclaim the space allocated to it but when I try to change the size or do a shrinkdb it either tells me I cannot shrink it smaller than allocated size or it shrinks tempdb to current (which is too large)... I looked online but could not find anything...
Any suggestions or assistance would be much appreciated... up to my eyes in tempdb..... Bill.
Hello friends.. We are getting below error every day.we have job Shrink TempDB which runs every hour..but once a day we are getting this error.Is this error becasue of other jobs also running by that time which uses huge resource from DB..I cant understand why???.. can any body have an idea??

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?
I have a problem with my TEMPDB Database.It gets extra size throughimporting data into one of my databases in same server.How can I shrink my TempDB Databse?Thanks
I'm running Sql 2000 with many users logged in. My tempdb database has grown to a large size 3/4 of it free space. Is there a way to shrink the database while users are logged on. I tried using the enterprise mgr. to shrink the tempdb database, but it did not work. How can I shrink this? It's using a ton of free space.
I have a tempdb that was created at 1Gig. I don't know why but I want to shrink it below the original creation size. Is there a way to shrink this file or create a new file and delete the old?
I have tried shinkfile and shrink database with no luck.
A customer on SQL7 has a 40GB tempdb (which is usually 2-5GB) which has filled the drive. ShrinkDb/ShrinkFile do nothing as the db has only 2GB of free space. How can I truncate the data or blitz tempdb and create a new (2-5GB) one (Stopping the server, deleteing the .mdf, starting the server creates a new tempdb with the same size as the old one!)

Hi, i'm using SQL Server Express (9.0.2047). My database's *.ldf file's size increasing everyday... How can i decrease it? How can i make ldf file to small ?
I have faced a network problem during some days, what forced one of our replications to be stopped. The Publisher database is a high volume database. After I re-started the replication, the Subscirber database has its transacting log size increased quickly, because of the high volume of information to be inserted.
My concern is the way it is working, there will be no enough space for the log or for its backup files.
So, I have created a TSQL job within the following commands:
BACKUP LOG database_name WITH TRUNCATE_ONLY DBCC SHRINKDATABASE (database_name,TRUNCATEONLY)
It's running every 20 minutes, however the transaction log remains increasing.
I have also changed the db_option "SELECT INTO/BULKCOPY" to TRUE, in order to avoid logging bulk copies, but I believe, it didn't work because it didn't apply to replication process.
Does Anybody know if I can disable the transaction log or avoid this incresing of size during the replication?
Thanks a lot! Regards, Felicia Schimidt felicia.schimidt@br.flextronics.com
I have a database with 1 .mdf data file and 1 .ldf t-log file. There are multiple inserts/deletes/transactions performed on the data daily, but the size of the two files remains constant (5,774,,336 and 153,480 respectively)??? I perform daily full backups and hourly T-log backups (during business hours of 9-6) and these backup files change size, but why aren't my physical DB files changing? I have them set to auto-grow at 10% unrestricted...
i have a very big database and number of people are working on it.. it's log file size is increaseing very day too much.. i am taking log back every 30mint...
i dont' know that wethare i need to truncate the log file after taking the log file backup or not.. i am taking differentail backup every day and full backup every week...
Please tell me do i need to trucate the log file to reduce the file size or i hv to leave as it....
I am trying to reorganise the log files on a server, (long story short they are fragmented so I want to shrink and reset the initial size and growth) and I am unable to shrink them. When I run the following:
use test DBCC SHRINKFILE(test_log, TRUNCATEONLY) --or use DBCC SHRINKFILE(test_log,2, TRUNCATEONLY)
I get the following message:
Msg 8985, Level 16, State 1, Line 1
Could not locate file 'test_log' for database 'test' in sys.database_files. The file either does not exist, or was dropped.
I get this message for every database on the server. I got the logical name of the file using sp_helpfile and have checked it against sys.masterfiles, sys.database_files and sys.sysaltfiles, all match up and confirm the name 'test_log'.
I rebooted the server last night and was able to shrink the first couple of .ldf's I tried so I presumed it was fixed. This morning when I try again i get the sanme error, I don't see anything in the SQL server or system logs that indicates a change.
I am able to add new log files and remove log files, however if I add a new log file (test_log2) and then try and truncate that file I get the same error.
I am using SQL Server 2000 with replication object for two location. Log size on publisher go upto 25 times of data file size, I mean 80 MB Data files has maintains 2 GB log file and it is same for all five co's working on same windows 2000 advanced server board.
Since last week server randamly get disconnected from user applications and at that time few tables are not openable at server.
Can any one give a reason ? Why this type misbehaviou done by SQL Server 2000?
The DB is in simple recovery mode. There are no open transactions (used dbcc opentran).
The server is running SQL Server 2014 and the DB is in compatibility mode SQL Server 2008 (100). It was upgraded to 2014 a month or two ago.
I have tried to re-size the log to 100mb, but any way I have tried (none gave errors), the log file remains the same size. I have tied to shrink the log file (through the UI and via DBCC commands) without success; no errors, but also no change in file size.
I have checked Log Reuse Waits, just in case, and as expected it showed “NOTHING” (select log_reuse_wait_desc, name from sys.databases)
I tried running a checkpoint, but that did not allow any resize or shrink to work.
I have tied creating large transactions to move the used point in the log file, in case this was the issue. I did this by creating tables that I drop after large inserts. While it shows me that the log space % used increased, the log file still does not allow the space to be reduced.
The following is what I was using for the transactions to get the log used.
BEGIN TRAN select a.* into testtable from sysobjects a, sysobjects b, sysobjects c ROLLBACK TRAN
Do I just need to continue running large transactions until the log space used gets high enough to get the “end point” in the log to really move? Is there an easier way to accomplish this (I have several DBs that have the almost identical problem), what I am using moves the Log Space Percent Used about a percent on each execution.
I'm having difficulty completely truncating my tempdb online log. It sits at 25%, and remains allocated even after I've truncated the log with backup log tempdb with truncate_only. Now, I would assume this to be normal if there is a spid who hasn't commited or rolled back a transaction, or if checkpoint hasn't run. However, running DBCC opentran('tempdb') shows me that there are no open transactions at that time, and checkpoint appears to be running fine.
Can anyone give me any hints on which way I should point with my investigation.
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...
I've production sql server 7 sp3 on windows NT. I had a 8GB data file ofwhich 5GB were used and 3GB were unused. I wanted to take back the unused3GB.So I did the following with EM GUI:1. I tried to "truncate fre space from end of the file". Didn't truncatethe file. I believe there was no empty space at the end of the file.2. Next I chose the option to "shrink file to 5GB". And to my horror thedata file instead of taking just 5GB took the empty spaces also and the sizeof the used data file went to 8GB.Any idea what's going on?TIA,SP
On a database with a log file that has an unrestricted file growth, the file size exceeds 1 GB. Since this excessive was caused by a badly written update statement, I want to reduce the size to about 200MB. After reading the BOL I was convinced that I only need to take two actions: truncate the log file (to create some free space in the log file)and shrink it. These are the statements I executed:
backup log ODS with truncate_only dbcc shrinkfile (ODS_Log, truncateonly)
After I executed these statements - BTW, there were no errors - the file size was still the same. Can somebody tell me why?
I have created a new database in SQL Server 7 with the auto grow options set to on. I then added a whole load of new data to the table which made the transaction log file grow to 20Mb.
I then truncated the transaction log to remove all the completed transactions. The Enterprise Manager now shows the Log to only have 3MB of data in it but the file is still 20MB.
I have tried setting the truncate log on checkpoint option, and tried running DBCC SHRINK DATABASE and DBCC SHRINK FILE commands but these seem to have no affect on the file size.
Does anyone have any idea what I might have missed/done wrong?
I have Disk Xtender 2000 which was made by OTG Software , Legato and now EMC. I have an NT 4.0 PC with Microsoft SQL 2000. I have a drive space problem and need to shrink a 38 gig .ldf file called OTG03.ldf I also have a 2 gig .mdf file called OTG03.mdf How can I shrink this .ldf file. I'm not a DBA so being specific is greatly appreciated.
My DB's recover model is SIMPLE. Is it OK to schedule a SHRINK FILE only on the log files regularly? Any GOOD vs BAD about my plan? I want to do this because the log files keeps on increasing. Right now, the log file s on ENABLE AUTOGROWTH, FILE GROWTH = 10%, RESTICTED FILE GROWTH = 2,097,152.
I am geting growth alerts and need to shrink a log file that is 99% full, but it won't let me. Here is the message I get. The transaction log for database 'SOM_System' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases
What can I do in order to shrink this log file?? Thanks
