Newbie question about reclaiming some disk space on our SQL server.
We currently have a db that has the following stats:
space allocated: 34734 MB
space free: 843.66
of this the current size of .mdf is 33877 MB and the space used is 33873 MB
the drive that holds this database is running out of space, what is the best method for me to use to reclaim some disk space?
I have read books online and am a little bit confused as to whether or not using shrinkfile on the .mdf will free up space to the OS? Do I need to do anything else before or after such as reindex? Also what is the overhead as we only have about 10% free on the drive.
If you have problems shrinking a transaction log no matter what commands you issue, here's a way to shrink the tranlog:
1. Right click on the properties of the database and go to the options tab. 2. Change the recovery mode to simple. 3. Right click again on the database - go to all tasks - shrink database. 4. Shrink the database. 5. Change the recovery mode back to what you had it as.
I found this out by trial and error as I could not find any documentation on it and no matter what I tried, I could not get the transaction log to shrink.
I have a SQL 7.0 sp3 server and I am trying to shrink a production database for use on other servers. The database/log sizes are 9601mb / 138mb with 772mb / 128mb free. I truncate a table that contains binary data. After this the database/log sizes are 9601mb / 138mb with 6634mb / 111mb free. The next step is to use EM to issue a shrink db. After this the database/log sizes are 6807mb / 378mb with 9.56mb / 365mb free.
After the use of truncate the the data in the datafile is about 2967mb. After the shrink db the data in the datafile is about 6797mb.
The size of the data grew after the shrink db was issued. I looked at the tables and the space is largely associated with two tables that have a binary field, but the number or rows are still the same. I ran a checkdb just to make sure that there was not a problem and no problems were reported. I have used this process many times and this is the first time I have come up with these results. Any suggestions? Thanks, Glen
Actually I have a 8.5 Gb database but the correct size that I need to due disk space is 5 Gb. When I make a backup, the size of the dump is 4Gb, so I wonder if I create a 4- 4.5Gb my dump db will fit in it, but not. Other way is create antoher db with 4 - 4.5 Gb and transfer via sql-transfer or sql-bcp but I got a message that my device is too short.
So I ask : What are the correct ways to reduce the size of a database ?
We just migrated our DB from one SQL Server to Another. Both DB's used to be the same size at 11GB. The new SQL Server is a whopping 33GB, and I can't seem to find out why. The new DM has fewer tables (the data is identical).
Does anyone know how I can compact or shrink my DB, know why or how it grew so much and didn't go back down to normal size, and maybe where I can search properties or change settings to find out what is going on and prevent it from happening again.
I know MS Access has a shrink utility, but don't know where it is in SQL Server.
I am trying to shrink a log file (.LDF), but it will not work. I am typing: BACKUP LOG "Database1" WITH TRUNCATE_ONLY dbcc shrinkfile ("Database1_log", 50) The microsoft site says this should work: http://support.microsoft.com/kb/272318/ ...but I can't get the file to shrink, at all? I'm sure the SQL services need to be running. I am logged in as my Administrator / sa. What could I be missing? Trying to shrink it too much? (THANKS).
A few of the databases I have are take up a lot of space, but when I look at the actual space that's being used, it's very small. I've tried shrinking them but they still remain at this bloated size. Is there any other way to reduce their size?
Txn log is nearly 10GB with only 60MB actually used. Disk has 150MB remaining. SQL 7.0 SP2. I've truncated the log several times. I'm aware that the active portion of the log can be at the end and have added many records to cycle the active portion round to the start of the log file. How big are these log segments?
I've run dbcc shrinkfile with and without a target size.
I've checked DBCC OPENTRAN. No open txns exist.
What else can I try? I've looked through similar postings and haven't spotted anything.
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?
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?
How do I shrink my transaction log file ? The physical file are 10Gb in size but only contains 100Mb data so I want to shrink it to save diskspace. I tried DBCC SHRINKFILE command but the file dont shrink.
Any other methods to shrink a transaction log file ? Like backup/restore ?
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
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.
I am in the process of copying database from large size to smaller size one. The actual data in the database is very less. When I try to shrink the database, I am getting message I can't shrink the database.
Can any one suggest on 'How to copy this database?'
Hi I have a SQL2k db ABC with only 2mb data but around 500 log.

question: 1. what is the negative -0.51 MB for unallocated space? 2. I can't kill all the process logins, is there other way to shrink the database log side?
I have a question that keeps my mind buys and I wasn't able to find answer on that.
I have a full backup recovery plan and I am backing up my Log files in every 15 minutes. At the same time My log files are shrunk in every 3 hours so Are shrinking the log files correct approach? If somebody enlighten me on this issue I appreciate it. Thanks LS :confused:
I get the error message below. Books online doesn't say any more. Can anyone explain? I am the only user connected to the db at the time, no jobs are executing.
Cannot shrink log file 2 (log) because all logical log files are in use.
(1 row(s) affected)
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
Ok. Thanks for the help today with helping me isolate why I have 2 almost identical databases, one is 11GB and one is 33GB.
I was able to find out that a few of the tables are way off in size proportions. In one database, the file is 354 MB, and the new DB, the same file is 8.9 GB!! The row count is identical and the number of columns is the same.
I tried dropping the table and an doing a full refresh, so my database is smaller, but there is still a lot of free space that won't go away when I shrink the DB.
1. Does anyone know the code to shrink each table one at a time? 2. Does anyone know how to remove the free space in my DB, the shrinkDB function is just not working.
I have Disk Xtender 2000 which was made by OTG Software , Legato and now EMC. I have an NT 4.0 PC with Microsoft SQL 2000. I have a drive space problem and need to shrink a 38 gig .ldf file called OTG03.ldf I also have a 2 gig .mdf file called OTG03.mdf How can I shrink this .ldf file. I'm not a DBA so being specific is greatly appreciated.
I have a production database in which data file takes 17GB and used 10GB. I want to shrink it. Once I take about one hour to shrink 1GB. So I am worry long shrinking time. Is there down time during the shrinking that doesn't allow user access?
My DB's recover model is SIMPLE. Is it OK to schedule a SHRINK FILE only on the log files regularly? Any GOOD vs BAD about my plan? I want to do this because the log files keeps on increasing. Right now, the log file s on ENABLE AUTOGROWTH, FILE GROWTH = 10%, RESTICTED FILE GROWTH = 2,097,152.
