Transaction Log Does Not Truncate And Shrink Using A SQL Server 2005 Maintenance Plan
May 15, 2006We are using SQL Server 2005 (SP1). I have created a maintenance plan that backs up up the datebase every night. The problem is that the transaction log is continuing to grow. I have been told that a full backup will automatically truncate and shrink the transaction log. However, this is not happening. How can I truncate and shrink the transaction log after a full backup as part of our maintenance plan. Thank you.

Apr 17, 2002A 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!)
View 2 Replies View RelatedWhy Truncate / Shrink Log Files Work The Way They Do???
Nov 13, 2007I've been having some trouble keeping my log file size under control due to some off-hours data loads. Currently, while updating some certain tables, the data base is still in "Full" mode, which of course makes the log file grow accordingly.
Today I figured out that, given the current scenario, in order to shrink the log file back down (after the table update), I have to (1) backup the log file, (2) shrink the log file, (3) backup the log file again, and (4) shrink the log file again. My question is: why do I have to do two iterations of backup / shrink? Why does it not work with one iteration? I just want to better understand the architecture and functionality.
Also, would there be a better way for keeping the log file size under control? If I switched the database to "Simple" mode to load the data, would that work any better?
If so, what might be the best methodology?
Thanks in advance for any responses.

Shrink SQL 6.5 Transaction Log
Mar 7, 2001Is it possible to shrink the size of a transaction log file in SQL 6.5. Normally in SQL 7.0 I use detach and reattach but this is not supported in 6.5. The log file for a 200Mb database is 749Mb with no unused space and no open transaction. Thanks

Sep 25, 2002Hi,
I have a t-log on one database which is 400mb when the database size is only 30mb. dbcc shrinkfile does not work and dbcc opentran shows no open transactions. When I tried to do a Backup log with truncate_only the following message displays:
The log was not truncated because records at the beginning of the log are pending replication. Ensure the Log Reader Agent is running or use sp_repldone to mark transactions as distributed.
The database in question is not a publisher and only receives 5 subscribed articles, none of which are changed very often. The database operates 24 x 7.
Does anyone have a solution to this dilemma?
Thank You

Mar 12, 2008
I have 4 large sql dbs. All 4 have been trimmed down by deleted recs from the db, then shrinking. 3 out of the 4 shrunk successfully and the log files are much smaller than the data files. On the 4th the data file shrunk to 14G, but the log file stayed at 47G. I have tried truncating and then shrinking, but it never gets any smaller.
Any suggestions on why this particular one will not shrink?
SQL 7.0 Transaction Logs Won't Shrink!!!
Jun 5, 2002I have seen quite a few people post this type of problem, but I am finding few solutions. Your advice and/or experiences are greatly appreciated.
Here's my scenario:
Environment: Windows NT 4.0 SP 6, SQL 7.0 (set up for Transactional Replication)
Problem: We have several remote dB machines configured for full recovery. On these machines are several dB's that are capturing aprox. 280 data points per second per unit. (Each dB represents one unit, and we have 21 units) No problem here. The problem is the transaction logs, that obviously grow profusely, will not SHRINK after, backups, dbcc commands and TSQL has been issued in failed attempts to shrink the logs. (in other words we've tried everything)
My questions are:
1. Because we are replicating, is it absolutely necessary to configure dB's for FULL recovery? How do I check in 7.0 if the dB is certainly in FULL vs. SIMPLE recovery mode?
2. I work with SQL 2000 and shrinking files is no problem. How can we shrink these log files in SQL 7.0?
It is rather urgent I find a solution as we are running out of hard drive space on our remote machines. Please help :-(

What else can I do to truncate my log?

Can't Shrink Transaction Log From 30GB To 1GB
Jun 1, 2000We have a user database that was initially allocated 90GB for data file, 30GB for transaction log file. We decided to shrink the data file to be 2GB, log file to be 1GB using 'DBCC SHRINKFILE'. The result of data file is 2GB as we expected. But log file is 5,764 MB no matter how many times we shrink it or run 'backup log with truncateonly' against it. Can this be something to do with how transaction log allocate its segments called virtual log files? Is 5GB the smallest unit of log segment that can be shrunked? Is there any way around this? We are in a production enviroment, and this is pretty urgent.
Thanks in advance.

SQL Server 7 Transaction Log - Can't Shrink!
Jun 10, 1999For some reason (I'm sure it was my code) my transaction log segments grew to a huge size (>1 GB each). They are normally in the area of 150 MB each, so I wanted to shrink them back down. But I have one transaction log segment that won't shrink! I'm a relatively new administrator, but I've tried shrinking the database (which worked for all but one segment) and truncating the logs, I've tried issuing a CHECKPOINT, I've tried stopping and restarting SQL Server, but I can't get that last segment to shrink to a normal size. Any ideas?
Thanks,
Robin

Aug 15, 2007
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?

Can't Truncate Transaction Log
Oct 7, 1999Hello,
We have a SQL 6.5 Server with several DB's on it. Specially there's a critical DB on two separate devices for the Data and Transaction Log. The Data Device is 700MB and the Transaction Log started 210MB. Yet, the truncate function of the Log Device is not freeing space on it. We have been forced to expand the transaction device up to 860MB!!!! which is an outrageous size for it. We have tried the DBCC CHECKTABLE(syslogs)followed by DUMP TRANSACTION <<db_name>> WITH NO_LOG and then once again the DBCC CHECKTABLE(syslogs).
We even tried to create a new DB only with the dat file, but this also didn't work. Our Server Disks are almost full, and we can't grow the device no more.
Any suggestions??? PLEASE IT's REALLY URGENT!!!!

Cannot Truncate Transaction Log.
Feb 27, 2004DB Newbie question ahead.
I have a mere 100MB db with a 4GB transaction log. I want to truncate the log as I understand that truncating it will shrink the log by removing the transactions that have already taken place. However, the option to do a transaction backup is greyed out. I suspect this is from the db being in transactional replication with another server; however, I don't know for sure.
Are there any other ways that I can shrink the transaction log? I would like to do shrink it without taking the db offline either.

Dec 11, 2007We do full backup every day and recovery model is Full, but we never done transaction log backup, so the transaction log files keep growing. What should I do?

Any suggestion would be appreciated.
Shrink The Transaction Log File In SQL7
Sep 6, 2001I have a database (sql server 7.0) that has some big unused space in the transaction log. I tried to shrink the transaction log, but it seems it is not working. I used the same procedures to successfully shrink the log file for database of SQL Server 2000.
Here are what I tried:
shrink database from the Enterprise Manager.
or
dbcc shrinkfile (Spoper_Log, 40)
backup log Spoper with truncate_only
Does anybody know how to shrink the transaction log in SQL Server 7? This is a production database and I can't afford to lose any data.
Mirroring :: How To Shrink Transaction Log On Mirrored DB
Oct 7, 2015Today, I became an involuntary DBA until my company finds someone else. We have an SQL R2 DB that is mirrored that failed dur to the transaction log growing and filling up the disk. As a band aid remedy, I was able to add 20GB to the disk (it is a VM) and then I backed up the Transaction log and did select log_reuse_wait_desc from sys.databases where name = 'mydb' and the result showed that the backup was successful (NOTHING, I think was the result).
After this I was able to resume the mirror and everything has been running fine. What I need to do now is to shrink the Transaction log so that if it starts to grow again, I will get an alert and can avoid today's issue. From what I have read, I can just use DBCC SHRINKFILE [logname] after I do a backup and the changes will be reflected on the mirror as well. I have shrunk the T-log in non-mirrored servers before, just don't know if there are any key differences.

Transaction Log Doesn't Truncate
Dec 29, 2007I use SSME to do a full backup of both the database & transaction log, selected "Truncate ..." in the options for the log backup. The log doesn't truncate.
I have looked at the reasons logs don't truncate in Books Online & can not find any that apply. There are no open transactions & in sys.databases log_reuse_wait is 0.
Any help would be appreciated.
