How do I shrink a log file in a database that's been mirrored?
DBCC ShrinkFile(id) reports the size can drop considerably, but even after a CHECKPOINT, it doesn't shrink.
DBCC ShrinkFile('name') says it doesn't find the file name. The properties dialog for the database in SSMS doesn't list any files, even though sp_helpdb says they're there.
Must I disable mirroring, fix DBCC ShrinkSomething, then re-enable mirroring? Can I just pause mirroring?
I am trying to resize a database initial log file from 500M to 2M. I€™m using€?
ALTER DATABASE <DBNAME> MODIFY FILE ( NAME = <DBLOGFILENAME, SIZE = 2 ) "
And I'm getting "MODIFY FILE failed. Specified size is less than current size." I tried going into the database properties and setting the log file to 2M, but it doesn€™t keep the changes.
Any help with this process?
I have a log file that is approximately 50 GIG. I backed up just the log and the file size of the .bak is 192 GIG . Why is this? Shouldn't it be closer to the 50 GIG.
Normally I wouldn't let log grow this much. But we are in process of getting new server up and running and don't have backups going yet. They are working on getting that up and running this week.
So I did a log backup to give me back some log space for now but was concerned when I saw the size of the .bak file.
When I view media contents of the backup device it shows one tranaction log back up and size of 192 GIG.
What is up with this. I know in SQL 2000 the log backup files where never this big. they were about the size of the log itself.
Any ideas?

I installed sql 2005 a while back. Then I recently found out my file system was fat32 (I don't understand why the hardware people did this...) and I had to convert to NTFS. Naturally the sql service no longer worked so I uninstalled inorder to reinstall now I can't reinstall it I keep getting this message
native_error=5039, msg=[Microsoft][SQL Native Client][SQL Server]MODIFY FILE failed. Specified size is less than current size.
I'll try to post the full log in a new post.

View 1 Replies View RelatedI am using SQl Server 2012 Database Mirroring with around 40 gb as mdf and 1 gb as ldf. Now my ldf size increased . How to reduce ldf size while mirror enabled with mirror server and witness server. Can shrink the ldf with mirror enables.
View 4 Replies View RelatedHere are my scenarios:
We have an application with replicated environment setup on sql server 2012 . Users will have a replica on their machines and they will replicate to the master database. It has 3 subscriptions subscribed to the publications on the master db.
1) We set up a replica(which uses sql server 2012) on a machine with no sql server on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 33gigs and ldf has grown to 41 gigs. I went to sql server management studion . Right click and checked the properties of the local database. over all size is around 84 gb with little empty free space available.
2) We set up a replica(which uses sql server 2012) on a machine with sql server 2008 on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
3) We set up a replica(which uses sql server 2012) on a machine with sql server 2012 on it. We have dropped the local database and recreated the local db and did the initial synchronization using replmerge tool. The mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
Why it is allocating the space differently? This is effecting our initial replica set up times.
I need to write a process to get file size in kb and record count in a file. I was planning on writing a c# console app that takes the file path and name as a param however should i use a CLR?
I cant put a script in the ssis when it's bringing the file down because it has been deemed that we only use ssis for file consumption.
What is the recommended size and file growth for a database and log file? We will be storing approx 10000 records a day.Currently we have the following:
CREATE DATABASE Dummy
ONÂ
PRIMARY
( NAME = Dummy_data,
  FILENAME = 'D:....DATADummy.mdf',
  SIZE = 250MB,
  FILEGROWTH = 25MB )
LOG ON
( NAME = Dummy_log,
  FILENAME = 'D:....DATADummy_log.ldf',
  SIZE = 50MB,
  FILEGROWTH = 5MB ) ;
GO
My question is what is the best way to manage the log file size in a Mirrored database session?
Setting log file to autogrow by %
Setting log file to autogrow by mb
Setting log file to restrict growth by %
Setting log file to restrict growth by mb
The above aforementioned followed by a backup log "dbnamehere" with truncate_only, followed by a DBCC SHRINK file I'm assuming is not an option since the log file is constantly being applied to the mirror.
I ask this because I have a DB that can pass some 1,000,000 rows into just one of my tables a day and I need to make sure about this before I flip the switch.
Anyone's help inthis matter is much appreciated.
Thx,
We currently have a 10GB database that is functioning properly mirrored. The only issue we have is that the log files grow very quickly during the early morning hours when a large number of transactions hit our DB from scheduled jobs. We have transaction log backup and shrink job that runs every 3 hours to backup the log and shrink the logical file to 10GB. In most cases this will shrink the log back down to it's desired size of 10GB. However, on some mornings it takes more repetitions of the log backup/shrink job to return the log size back to "normal". During this these times when it does not shrink the DB effectively, I get a report of the job process by email that states "Cannot shrink log file 2 (e_Log) because all logical log files are in use." I run a DBCC OPENTRAN command, and there are no open transactions. Eventually, the log file will return to it's normal size of 10GB through the log file backup job. I have a few questions though.
1. Is this normal behavior during moderate database use?
2. Does mirroring have any effect on the SIZE of the log file?
3. Is it normal for the size of the data file to be smaller than the size of the log file on a heavily used database?
4. Does anyone have any suggestions to better maintain the log file size?
Thank you,
Greg
I have a database whose log file size is 4 time greater then data file size, and its continuously growing day by day. Recently face limited disk related issue.
Is there any way to truncate log file???
What is impact on db if i truncate log file???
Is there any way to prevent this file continuously growing???
is there limitation for size of file to store in db by filestream in sql server 2008?or it accept all sizes?

I'm trying to add a new transaction log file to a database with mirroring (high safety, automatic failover).
When I add the new transaction log file via SQL management studio, the mirroring status becomes suspended. When I try to restart mirroring, it attempts to re-synchronize and then goes back to the suspended state. Only after I delete the new transaction log file can I sucessfully restart mirroring.
Can you add a transaction log file to a mirrored database? Any ideas would be appreciated.
Also, I'm not sure if this matters, but I am trying this in my development environment and all 3 instances (principal, mirror, witness) are on the same server. It's a long shot, but I thought maybe both the mirror and principal are trying to create the file at the same location on disk.
Thanks,
Don

We have 2 SQL Server 2k5 servers running the same build - 9.0.2047 . When I backup any database from one server and attempt to restore it to the other, the log file generally increases by 100 fold. It errors out after I try to restore a 100MB db and it tries to create a 9.8GB log file. This happens both when I use the GUI to restore and when I restore from a T-SQL script. What am I doing wrong?
Thanks in advance.
When Create Mirror Database Server, Where need to store the Transaction Log backup file?I took FULL Backup of my Primary Database, and I restored at my Mirror Server also. When I try to create a Mirror Database."The remote copy of database "<db_name>" has not been rolled forward to a point in time that is encompassed in the local copy of the database log. (Microsoft SQL Server, Error:1412)".I am misplacing the Transaction Log backup file. Where I need to store that file?

Server A = primary SQL DBs (mirroring origination)
Server B = failover SQL DBs (mirroring destination)
For database mirroring a witness is required.
Can the witness live in another instance of SQL on server B?

I am currently trying to get file sizes and insert them into a table. The table already has the path to the actual file, so its just a matter of using that path and getting the size.
Any help is appreciated

Thanks!

How the size of transaction file is calculated. are there any standards.
I created my database with 2000 mb data filesize and 200 log file size.
now my datafile size has reach to 11000 mb but log file size is still 200.
Therefore when I take the online backup my logsize totally consumed and I have to cancel my backup.
Please reply ASAP.

My Database Log file Size Increased dramatically upto 5GB. My Data file size
is only around 600MB. Almost my Harddisk space occupied fully by log file. How I reduce the log file size. Anyone can give me some tips?.
I created a database and had its file size as automatic grow. Now the database file is of 17 MB and its transaction log file size is 230 MB. After checking transaction log file properties I came to that it is using 13 mb only and the rest of the 230 MB i.e 217 MB is free. I want that area in the transaction log to be freed and get the transaction file size to its actual size. Any help will be greatly appreciated.
Thank you in advance.
P.S: It is very urgent.
I am using SQL 7, SP1 / NT 4. The .LDF file has grown to 1.1GIG; I ran a DBCC SQLPerf(LogSpace), the used portion of the log is 2%. When I run a DBCC Shrinkdatabase and DBCC Shrinkfile, the log file does not reduce in size. How do I get the virtual log files that are not active released back to the system? Is there a way to tell if all the virtual log files are active, therefore, not reducing the size of the file? Any help is greatly appreciated.......
