HDD Still Full After Shrinking Transaction Log
Nov 24, 2006
Hi All,
My SQL server transaction log is getting bigger every day and my HDD if
running out of space.
So i follow the MS KB about how to Shrinking the Transaction Log.
After doing so the log is much much smaller as i can see the size of it
under enterprise manager.
The problem is that the HDD still shows the same size.
If i shrink the DB why the and reduce its size why the HDD does not
shows it?
Is there a way to clear the size from the HDD?
Thanks All

BOL says should not manually truncate log in full recovery mode unless you make an immediate full backup because you will invalid the log sequence. Does DBCC shrinkfile(log_filename) with notruncate also invalidate the sequence? Is there any way to shrink logs between full backups? (I do back up the logs frequently, but often it needs a shrink statement to keep size under control still during a certain time window). Thanks.

I have a webhost where it seems my control of my database is fairly restricted. I cannot backup the database because I don't have the necessary permissions. I cannot perform a DBCC SHRINKFILE (permissions) - and many other DBCC commands. I ran into a problem where my log file filled up during the middle of the day and impacted my operations - data was lost.
I found some TSQL for shrinking the log file, but the statement:
SET @TruncLog = 'BACKUP LOG [' + db_name() + '] WITH TRUNCATE_ONLY'; EXEC (@TruncLog)
will not execute because I cannot execute the BACKUP LOG command (permissions)...
Is there anything else I can do, or am I to far up the creek (w/o my paddle)??
Thanx
Jerry

I've been trying to shrink my SQL 7 Transaction log after it had grown to 30+GB's. After running the command dbcc shrinkfile 'filename' and the new size, I'm getting a result set of:
DbId FileId CurrentSize MinimumSize UsedPages EstimatedPages
------ ------ ----------- ----------- ----------- --------------
6 2 640 128 640 128
(1 row(s) affected)
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
However my transaction log remains the same size. Any advise would be appreciated!

I'm having a problem shrinking my transaction log. I have a 1GB database with a 500MB transaction log. The transaction logs are backed up every 10 minutes but it has grown to 2.2GB. I've tried backing the transaction log with TRUNCATE_ONLY and then tried doing a DBCC SHRINKFILE but it doesn't seem to work. I've checked if there were any old, long running queries but there is none. What else can I do to reduce the transaction log size?
I've had a thought to create a secondary log file and then delete the primary but that isn't allowed. Is there anyway I can make the secondary log file the primary and vice-versa? This way I should be able to delete the secondary log file to reclaim space.
Any assistance is appreciated...
Many thanks,
Michelle

We have a database that was created with a 50 MB transaction log, that is set to autogrow. Due to activity the log periodically grows to over 200 MB. So we expanded it to 200 MB. But everytime the log is backed up, it shrinks to it's original size of 50 MB. The autoshrink option is not set, and no one is manually shrinking the log.
Any idea what could be causing this?
We are using SQL 7, SP 3.
Thanks!

Hello all,
I am having a problem truncating a transaction log. The truncate and database shrink commands execute successfully, but do not reduce the size of the transaction log.
Thanks in advance for any help on this issue

Hi All,
I have steps that I take to shrink transaction log. One of the steps is to delete the transaction log after I detach the database. Am I losing any data by doing that?

I have a transaction log with 22mb of used space and 2,632.50MB of free space. I tried using the following statement to shrink the log and it did not do anything:
USE DB
GO
DBCC SHRINKFILE (DB_log, 50)
GO
CHECKPOINT
Can anybody help me understand what is going on here?

My transaction log blows out to more than 55 GB when I run an index rebuild on a fairly large table. It’s ok for the transaction log to get that big but I want to shrink it back down ASAP while maintaining the integrity of my transactional backups. I’m thinking of a process something like the following:
1.Full database backup
2a.BACKUP LOG database-name WITH TRUNCATE_ONLY
2b.dbcc shrinkfile(2,20,TRUNCATEONLY )
3.Full database backup
Is this the best way to shrink the T-Log while maintaining the integrity of my transactional backups?
My database is MSSQL 2000 sp4 in full recovery mode.

My logfile for a DB grows very rapidly and grows to more than 10gb every night,i have scheduled a job to shrink this file.
Now in job activity monitor it is showing me a yellow triangle in front of the job and status as successfull and it has ran only for 1 second
It is not shrinking the logs
I have transactional replication implemented
My point is when the logfile grows more than 10 gb the job does not shrink the logs
I have got around 8 steps in thos job and this is the 7th step
Please Advice
Thanks

I'm using SSEE as part of SharePoint 2003. The transaction logs are growing rapidly but don't appear to clear down.
As its SSEE I've been so far unable to connect using Management Studio or Enterprise Manager, so using DBCC Shrinkfile isn't an option.
Can someone please help? I'm surprised that when installing SP I didn't get the option to choose a db type or location.

Hello all,
I am currently having a rather pestering issue with my full/transaction log backups. It seems that after running either, my logs do not truncate and the file continues to stay @ the current size and eventually fill to the brim. This issue only began after mirroring was setup. Is there any differences in log file maintainence when dealing with Mirrored databases ? I made my last attempt to run backups and waited over the weekend for some hope that a checkpoint would occur and my file would be shrunk once again for normal use.
Any insight on this is greatly apprecieated.

I am working on deploying my production DB's to a new server and am looking for some advice. The new server is running RAID-5 (the old one is RAID-0) but it only has one controller therefore I can not create another array group. So I was wondering since the disk setup is C: and D: (Virtual Drive) if I would see any benefits from placing my log files on C: and my Data files on D:?
The other question is related to the size of my log files. Some of the DB's were not created by me and there are no constraints in log file growth causing some very large TRANS logs. For example, there is a 100 MB DB with a 1 GB trans log. I restored the DB on my new server and truncated the log file (manually, the Ent Mgr Shrink DB tool doesn't work worth a hoot) to half the size of the DB and it functions properly. I was just wondering if this would cause any problems down the road if I did all of my DB's like this?
I am restricting log file growth to approximately half the size of the DB.
There is one DB that is 1.5 GB and the log file was set restricted to 2mb and it works fine, but I feel that I should bump this up a bit.
Any recommendations?

Gurus,
I have inherited a SQL 2000 database ( (I am new to SQL DBA) and I found this when I was checking the db properites . The transaction log has grown bigger than the actual data file, I thought transaction log backups would truncate the inactive portion of the log file and shrink the transaction log, but it was not the case it seems, may be it was truncating the inactive portion of the log, but not shrinking it. This site does not have a job for truncating the data/log files periodically. What is the best method to deal this situation, how can I shrink the Transaction log quickly?,
All your suggestions are welcome.
TIA,
-Jay

I have a transaction log which is 1 Gb and only has about 40 Mb free. When I run DBCC loginfo I find the first active log dates back to the middle of August. Does any one have any suggestions on the best way to approach this situation. How can I query the transaction log to find out what the old transactions are? I was going to use the detach database, rename log, attach database to shrink the log but don;t want to do this incase there is active data in the log. We are doing hourly log dunps.
Thanks

Hi there,
I'm still fairly new to SQL server and I've just ran into a problem when dropping some tables from my DB as my transaction log has become full. I looked at books online and it basically said to backup the log so it will also truncate the log. However I've ran out of disk space on my data drive so can't take a backup.
Is there a way to just truncate the active log to shrink the size?
Hope you can help??
Thanks

Today, one of our backups failed due to the transaction log being full. I expanded the transaction log and then the backup completed normally. For a short term resolution, I increased the maximum allowed size on our transaction log files.
We are doing a database backup only as follows:
backup database xxxxx to xxxx_data with init
I did find a note stating that the transaction log will eventually become full if doing a transaction log backup only. We do not generate a lot of transactions so I had not seen a need to backup the log during the day. The full database backup is done daily.
My question is, in order to permanently resolve this error do I have to:
- take a transaction log backup as well. Should I take it take right after the full database backup or at some later point.
- do I have to schedule/run the shrink database command.

I was trying to create a table on a Database and it gave me this message:
'tblSuggestion' table - Unable to create table. The transaction log for 'Database' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases
And I don't see the log_reuse_wait_desc column anywhere.
Any ideas?

Hi,
At the start, transaction log size is 1MB. at the middle of the dts it reached to nearly 2 GB. I encountered this error in DTS:
OnError,,,CallerType, CallerChannel, Dealer, DODealer, HotlineType, Model, Reg'l Signal Code, Account, Contact,,,10/22/2007 10:55:43 AM,10/22/2007 10:55:43 AM,-1071636471,0x,SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E14.
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E14 Description: "The transaction log for database 'DB1' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases".
I visited the sys.database's log_reuse_wait_desc and it is set to checkpoint.
The transaction log keeps getting full in the middle of the dts, not enough to do the 1 round execution of the dts. What to do with this one? Anything that i need to add in my dts to truncate the logs?

hi,
if my transaction log is full, do i need to execute only this command to truncate old logs?
DBCC SHRINKFILE(<dbname>, 1)
BACKUP LOG <dbname> WITH TRUNCATE_ONLY
DBCC SHRINKFILE(<dbname>, 1)
Should I use the same command as a daily maintenance to my transaction log?

Well, when I start thinking: I got it all, I run into a new problem.
I'm trying to execute a package that contains several (7) sequence containers each of them deleting all the records from 7 tables and inserting new rows.
I get the following error:
The transaction log for database 'MyDB' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
What the heck?

Hi guys,
I am developing this site http://www.onlineacademicadvisor.com and having DB problems for the 3rd time in a row.
Whenever the traffic on the site is getting bigger, the transaction log becomes full and no user can login. This problem is described at http://support.microsoft.com/kb/317375 From there, I got the feeling that the problem occurrs if transactions are not committed and last for too long.
However, I do not have any explicit transactions, just the usual select, insert, update statements in stored procedures. I do not call COMMIT (or RETURN) explicitly at the end of my stored procedures though. My stored procedures are short.
Have you got any ideas about what can cause the problem? I really have not idea what that could be.
Your help is much appreciated.
