Shrink The Transaction Log File In SQL7

Sep 6, 2001

I 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.

Transact SQL :: Cannot Perform Shrink File Operation Inside User Transaction

Sep 18, 2015

I am getting an error about "Cannot perform a shrinkfile operation inside a user transaction", but I don't have a shrinkfile command in my procedure.  Does SQL hang on to that command if it was received earlier in a different procedure?

SQL7.0 Shrink

Apr 14, 2004

Need some help here!

I'm trying to shrink a 20GB mdf file. I'm using SQL7.0 sp2. I'm using just 1 mdf.

I've tried using the 'shrink' option from enterprise manager. This just increases the size to around 35GB.

I've tried doing the shrink selecting just page re-order. Again the mdf increases to 35GB.

I've tried increasing the size of the mdf to 30GB and then shinking. Same result.

I've tried using DBCC shrinkfile. Again the mdf increases to around 35GB.

I've tried using DBCC shrinkdatabase. The mdf increases as above.

I've tried ungrading to SP3. Same result.

Any ideas??? Apart from upgrading to SQL2000.

Shrink SQL 6.5 Transaction Log

Mar 7, 2001

Is 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

Cannot Shrink Transaction Log

Sep 25, 2002

Hi,

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

Transaction Log Will Not Shrink

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, 2002

I 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 :-(

Transaction Log Doesn't Shrink

Hi Everyone,
I have a SQLServer 7.0 conversion db. Data file is 89 mg. The log has grown into 238 mg. Db and log are backuped nightly. Optimization and integrity jobs run weekly. The transaction log keeps growing! Truncate log on checkpoint is on and autoshrink is on.
What else can I do to truncate my log?

Can't Shrink Transaction Log From 30GB To 1GB

Jun 1, 2000

We 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, 1999

For 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

Transaction Log Backup Did Not Shrink Ldf - Help Please

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?

Thanks!

SQL7: Option "Transaction Log" Not Available

Feb 22, 2001

We've a strange problem with SQL7/SP2:
For two out of three databases we are not
able to choose EA backup's option "Transaction log".

It is simply dimmed off. Only options "DB complete"
and "DB differential" may be chosen.

We already re-booted our server without success.

Any ideas what's going wrong here?

Mirroring :: How To Shrink Transaction Log On Mirrored DB

Oct 7, 2015

Today, 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.

SQL 2012 :: Argument Daily Transaction Log Shrink?

Jul 7, 2015

For 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?

SQL 2012 :: High Availability Group Transaction Log Shrink

Feb 3, 2015

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?

SQL Server 2008 :: Unable To Shrink Transaction Log - Could Not Locate Files

Jan 10, 2012

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.

Transaction Log Does Not Truncate And Shrink Using A SQL Server 2005 Maintenance Plan

May 15, 2006

We 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.

Shrink File Tool From EM Took All The Empty Space Allocated To Data File

Jul 20, 2005

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

How To Shrink A Log File?

Oct 20, 1999

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?

Thanks,
Stef

My SQL 7 Log File Won't Shrink

Aug 27, 1999

Hi,

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?

Yours well and truly stuck,

Martin

Log File Can't Shrink

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??

Log File Shrink

Apr 30, 2008

I have noticed many times, even after log backup, shrink file (SSMS) is not reducing the file size. Even though there is free space shown in SSMS.

Subsequently I change the recovery type to SIMPLE and shrink – that does the trick for me.

Does anyone know why does this happen? Is there a better solution?

Trying To Shrink The '.mdf' File

Jun 4, 2007

Hello,

I have a database that the '.mdf' file is just huge. The physical size on disk is approximately 110 gig. I run weekly maintenance plans to rebuild the indexes on it.

I ran the 'sp_spaceused' command and got the following results:

database size: 106996.25 MB
unallocated space: 9614.35 MB
reserved: 99716504 KB
data: 13968056 KB
index_size 4002184 KB
unused: 81746264 KB

I was trying to clear the unused space, the numbers are telling me that I have 81 gig of space unused, but no matter what I do the '.mdf' file will not shrink.

I ran the following command: DBCC SHRINKDATABASE ({dbname}, 10,TRUNCATEONLY)

Any thoughts?

Thanks for the help

Richard
