I can't believe how many tempdb's there are?
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.
Hi Guys,
Tempdb in one of our SQLSERVER is standing at 5GB. I try to shrink it to 2GB, using following commands.
DBCC shrinfile(2,2000)
DBCC SHRINKDATABASE (tempdb, 2000)
It doesn't want to shrink at all... I ran sp_spaceused it give following results
Reserved data indx_size unused.

I dont understand why tempdb doesnt want to shrink...?? help is greatly appericated.. thanks..
Does tempdb ever need to be shrunk, or have it's log (does it even have one) dumped or does sql server handle this chore?
View 2 Replies View RelatedOne of my boxes was built with all of the system databases on the C: drive, and tempdb is up to 2 GB and there is no room left on the drive
It should have been installed on the D: drive
I've never had to do this before, mostly because I never install sql serevr on the c partition
Any war stories or suggestions

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.

Thank You in advance
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.
Thanks Jeff
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!)

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.
I am a bit confused. I was told that backing up the TLog cleared out all the commited transactions which shrinks the log. Is this true, becuase I started with a 72 gig transaction log and the created a maint plan to back it up as a .trn. After this was successful the 72gig .ldf was still the same size. What am I doing wrong to get this log size down?
Thanks!
Hi,
I am in the process of migrating databases from a SQL Server 2000 server to a 2005 server.
I have taken full backups and restored without recovery on the 2005 server. I now need to take transaction log backups and restore with recovery tonight to complete the operation. My question is this:
Some of the transaction logs have grown very large. Is it safe practice to perform a backup tran with truncate only and then run dbcc shrinkfile to reduce the size before I back up? This would make the process much quicker.
Thanks.
I'm running full recovery mode and doing log shipping so changing to simple mode is not an option.
I'm running BACKUP LOG right before and when I check it says my log is 99% free (on a 180GB log).
When I do DBCC LOGINFO('dbname') right before and after I see a dozen entries and they are all over the file and not just at the starting offset areas. The BACKUP LOG doesn't clean out the file completely.
Is there any explanation for this? Even though I'm doing this at off hours, is it possible that someone on the site in that split second is putting new entries in the log? Why are they spread out though? If they just put entries at the beginning I could shrink the file to a normal size still.
Hi,
Is it possible to shrink a DB thru .NET.
Presently I have to go into the SQL server 2005 studio to shrink the DB.
To shrik the DB I right click on the DB and select all tasks -> Shrink -> DB
How would I do this thru SQL codse?
I would like to do it thru my VB.NET code as you would compact an ACCESS DB.
The reason I want to set it thru my code is :
The clients that use my program have no clue of
SQL or for that matter computer itself.
I just want them to click on a button on my application which should
do the shrinking.
Similarly for backup of the DB.
Tnx
I have two server A & B and I have always on high availability turned on SQL14.
I need to shrink the log on server A and it's fine if it also needs to shrink B.
My problem is that when I run my shrink command I get:
"cannot be shrunk until all secondaries have moved past the point where the log was added.."
I think I need to drop the High availability on the servers and then run this:
USE iTest2_Claims;
GO
ALTER DATABASE iTest2_Claims
SET RECOVERY SIMPLE;
GO
DBCC SHRINKFILE (iTest2_Claims_Log, 10);
GO
ALTER DATABASE iTest2_Claims
SET RECOVERY FULL;
GO
If the only way to shrink my log file is to drop high availibity how do I do that in script? and how risky is it that the high availaibity will not re-connect?
I would like to know what happens if i shrink the database with truncate only option and do a full backup or transaction log backup ? are the full backup or transaction log backup valid? I know that the performance of the database is bad if i shrink the database. What happens to full backup or transaction log backups?
View 9 Replies View RelatedHelp,I have a database that has a data file of 2GB and a log file of 31GB.In enterprise manager, when I choose shrink it says there is 30GB ofunused space. When I shrink the database, it does not shrink,(however it says it has completed).I've done a complete backup, tried shrink again, no dice. I thenbacked up the database (which the backup was 1.9GB), deleted thedatabase and made a new database with 2,048MB for the data and samefor the log file.When I restore, the log file jumps up to 31GB again. When I check thespace when I use the shrink, it again says I have 30GB of unusedspace.How on earth do I get this file to shrink?I've been able to shrink other databases, but not this one.TIARob
View 1 Replies View RelatedFor a few days now I have a discussion with a colleague about shrinking the transaction log as a daily maintenance job on an OLTP database. The problem is I cant figure out a way to convince her she is doing something really wrong. Its not the first discussion.. Maintenance Plans.
She implemented this "solution" with a lot of customers as a solution against VLFs fragmentation and huge transaction log sizes. My thoughts about doing this is very clear and I have used the following arguments without success to convince her:
- To solve too many VLFs you have to focus on the actual size of the transaction log and the autogrowth settings in combination with regularly transaction log backups. Check the biggest transaction and modify the transaction log size based on this. Not use shrinking as a solution for solving many VLFs.
- Shrinking the transaction log file on a daily basis that is disk I/O intensive. When the transaction log file is too small for new transactions, the transaction log needs to grow and this will cause disk I/O, this can cause performance problems.
- It looks unprofessional.
These steps are used every morning at 6:00 AM and a transaction log backup is made every 30 minutes.
Step 1
DBCC SHRINKFILE (N'' , 0, TRUNCATEONLY);
go
Step 2
ALTER DATABASE
MODIFY FILE (NAME = N'', SIZE = 4098MB);
GO
My main purpose is making sure the customers have the best possible configuration and I cant accept this is being implemented. Are there any more arguments available for this issue?
I have a Customer running a database in a High Availability Group and I am not familiar with the set up... They have a transaction log that quadrupled in size during a data import and update which was generated by an external application. They have limited server space and would like to shrink the log again now as this import / update only happens once a year. The way this has always been dealt with in the past was by shrinking the DB and logs after the update.
Now however, when attempting to do a log or db shrink, an error message is generated which says that the log cannot be shrunk as the DB is in use as part of an Availability Group....
The more I search and try to read up on this subject, it looks like the DB has to be removed from the Availability Group before the log can be shrunk and then the Availability Group has to be re-created or restored in some way. Is there a simple solution to this conundrum?
I have got SQLv6.5 SP5a with SMS1.2 SP4 on seperate Alpha boxes. I have automated the backups so they are scheduled for after hours. SMS gets backed up first and TEMPDB shortly afterwards. However, since a back log in SMS MIFS has happened, the TEMPDB backup displays of 100,000pages backed up. When you back it up on its own, it only shows 170+ pages.
The SMS DB is 600MB in size, the Log is 210MB, Open objects is 5000, and TEMPDB is set 210MB on its own device.
Any ideas

Hi all
SQL 2005 SP2. Upgraded from 2000 and migrated maintenance plan. I am now getting an error when running the maintenance plan for all System databases:
failed with the following error: "Backup and restore operations are not allowed on database tempdb.
BACKUP DATABASE is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Someone else has the same problem and reported it here:

It is possible that Data Collection can cause massive increasing MB/sec to tempdb ? I cannot find connection with tempdb and I set cash file, but on same disk.
Or it can be something different? Last two weeks what I checked was Read/Write MB/s to tempdb increasing progressively.
One time it was about 20MB/sec
After it was reseting and again 1MB/sec..
What I checked , External company which install SQL Server made one file for tempdb, next week or during breaktime(it will be possible), I would like make 8files next weekend work.
Now I saw that TempDB mdf was still increased, but using was just 8-10%
I have added ndf to tempdb for checking performance improvement.... Now I want to remove the ndf file... I am using below command...

ALTER DATABASE TEMPDB Remove FILE tempdev1

I'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...
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?
On the SQL Server the Event Viewer shows the same messages and errors every evening between 22:05:00 and 22:08:00. The following information messages are shown for every database:
"I/O is frozen on database <database name>. No user action is required. However, if I/O is not resumed promptly, you could cancel the backup."
"I/O was resumed on database <database name>. No user action is required."
"Database backed up. Database: <database name>, creation date(time): 2003/04/08(09:13:36), pages dumped: 306, first LSN: 44:148:37, last LSN: 44:165:1, number of dump devices: 1, device information: (FILE=1, TYPE=VIRTUAL_DEVICE: {'{A79410F7-4AC5-47CE-9E9B-F91660F1072B}4'}). This is an informational message only. No user action is required."
After the 3 messages the following error message is shown for every database:
"BACKUP failed to complete the command BACKUP LOG <database name>. Check the backup application log for detailed messages."
I have added a Maintenance Plan but these jobs run after 02:00:00 at night.
Where can I find the command or setup which will backup all databases and log files at 22:00:00 in the evening?
Using Ola Hallengren's scripts I do a full backup of a database on a Sunday. Then differential backups every 6 hours and log backups every hour. I would like to keep a full week of backups based off the full backup done on Sunday. Is there a way for me to clear out the diff and log folders after the successful full backup on Sunday nights?
