Shrinking Transaction Logs And Placing On Different Drives
Oct 6, 2004
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?

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 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.

Hi,
I know that SQL Server (MSDE), databases run much faster when the data and log files are on seperate physical devices. I can do this explictly when I write a CREATE DATABASE SQL script, but would like to change the MODEL database so that all new databases use the sperate data/log file assignments by default. I haven't found a way to alter the sysfiles table in model - I can read the data, but it balks at trying to update it. (recordset is not updateable, or adhoc querries not allowed against a system database).
I didn't see any options on the MSDE install that implements seperate data/log paths.
I don't have the SQL Server tools (like Enterprise Manager) available, but I do have VS.NET 03 (Standard). And Web Data Administrator.
Any suggestions? Thanks in advance.

I have a transaction log file which is 29 GB in size. I am trying toreduce it by using dbcc shrinkfile with truncate_only but, it has noaffect on it. So, I tried to look at the logs by running dbcc loginfo(dbname). The last log is what's active (status is 2). How do I makethis status to wrap to first log so that dbcc shrinkfile would work?All other logs have status of 0, after running backup log dbnametruncate_onlyThanks.

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?

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.

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.

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 need to move transaction logs to a different drive and am looking for a way to do it without detaching the db.
Can I create a second transaction log file for the DB and then delete the original log file?
What is the best way to do this for db's that are being replicated?
Thanks,

i have several sql servers doing maintenance plans and backing up the transaction logs to tape. unfortunately it seems that the server keeps adding the transaction logs to the same tape, without overwriting them. Nowadays a transaction log backup to disk takes 2 minutes but when done to tape it is taking up 1hr54minutes. What can i do so that the tape is automatically initialised without having to do it manually... Thanks

Hi, I know just about nothing about SQL Server. I am getting this error:The log file for database 'my_database' is full. Back up the transaction logfor the database to free up some log space.I can't access the transaction logs to back them up. I am told that my ISP'stech support should have it set up to shrink those logs automatically everyso often. Is that true?Why are they needed? Up till Monday, the logs are just of our getting SQLServer set up, so couldn't the logs just be deleted? Most of my site can'trun with this problem.I'd appreciate any enlightenment anyone can give me!Thanks, Jill
