I have dataware house database and it's size is 2 TB with simple recovery model.I want to reduce it's size because everyday before loading table gets truncate.Is it best practice to shrink the datafiles?database having 5 data files and one log file.what is the best way to reduce?
I have a database file LEAR_Index(yes, it hold index data) from a havehave recently removed a bunch of data.It is about 120 Gb, 100Gb of which is not used. I wan´t to shrink thefile to lean 30-40Gb.I´ve been trying this:dbcc shrinkfile('LEAR_Index',40000)But to no apparent avail; the file did not shrink.I´ve tried using enterprise manager for this but it consistenlycrashes when performing this operation.#Any thoughs, idear as to what i might be doing wrong?
We have a database in production which has free space about 200 GB in Data files and Index files, I want to shrink Data files and Index files.If I do incremental shrink in daytime does it hurt the performance of the database or please advise what is the best practice.
I am trying to modify the files path (primary file, log file) of databases, but it looks like I am not able to mofidy their files path directly from the database property dialogue? Would please any experts here give me some ideas on what else can I try to figure it out? Thanks a lot in advance and I am looking forward to hearing from you shortly.
I have C,D,E drives on server. Data files will be on D and Log on E. My question is what is best practice for data and log files for system databases during sql server installation selection? Should they be on C drive along with SQL Server installation or D & E? If they should not be on C then what is the reason and what is benefit to move them on other drives.
When opening .sql files, I get a connect to database engine prompt every single time. how to stop this from prompting vs. just using my current active connection?
Damn, people, how to shrink log file. I've tried several times with DBCC SHRINKDATABASE ( database_name , TRUNCATEONLY) and DBCC SHRINKFILE (log_name, final_MB, TRUNCATEONLY)
and the log still is _untouched_
I have got big table, about 190 mln records (15 GB) and after simple update the log is very big but unnessesery.
we are running on sql server 2005 and in some of our production databases the log files are twice as bigger than the data files. we are planning to reduce the log file size. I saw the option on the management studio to shrink the log file. I just have some questions on this. as long as we are doing on the production server can we do that while the database is online or do we need to take the database offline? any help would be appreciated. Thank you!
Hello everybody. I have SQL2000 sp3 standard with 50 db's
All db set for full recovery and autoshrink Backup done with Tivoli
full backup once a week log backup done every 12 hrs
Problem .. shrinking logs
every 20 min I run job DBCC SHRINKFILE (My_db_logFile) for every db
70% of the time I am getting message similar to ------------- Cannot shrink log file 2 (Wholesale_Log) because all logical log files are in use. -------------- 1. I checked with sp_who2 The is no activity on db 'Wholesale_Log' or any other db returning "Cannot shrink..."
Why i getting "Cannot shrink ..." ?
even if job runs right after backup of the log files ,I still have messages.
Hi, I have some doubts about Shrinking databases or files. while shrinking a file, I learned that we are alllowed to shrink more than the minimum size of the file, does not it bring damage to the data in that file ??
I've been tasked with taking over the support for a client's SQL Serverdatabase. I'm not a DBA by profession, I'm a software developer whouses SQL Server as a database designer.The clients have reported that the server is running out of disk spaceand examination shows that the log files for several of the databasesare at 5Gb or more.After reading around the subject I suggested the following sequence ofoperations:-- Select the name of the database you want to shrinkUSE MyDB-- Dump unwanted transactionsdump tran MyDB with truncate_only-- Get the name of the logfileSELECT * from sysfiles-- Having examined the rows returned by this use the log file....-- Shrink the file to required size (in MB)DBCC SHRINKFILE('MyDB_log', 10)Is this a reasonable approach? Please bear in mind that I'm pretty newto this, and I have many other tasks to do besides manage the server.A previous DBA has set up good maintenance plans etc. so everything isbeing properly backed up (well, I think it is)If this IS a good approach, would it be reasonable to do this on, say,a monthly basis as a scheduled job? Obviously the stepSELECT * from sysfileswhich gives us the physical name of the log file would be removed andthe job would operate explicitly on each log file for each database inturn.Many thanks for reading.William Balmer.
I have a no of databases in full recovery model whose files are many times their datafiles. It is because these databases were copied from the development servers and in the development servers they were not taking the transactional log backups although once in the production server it is ensured that a transactional log is taken once in a day atleast. I plan to shrink the logfiles using the dbcc commands. However I am afraid that it may lead to severe defragmentation and performance hits.
We are using Sql Server 2008R2 enterprise edition which is clustered.
In this context my questions are:-
1)What is the best course to do the shrinking of log with out defragmentation?
2)Can I do the shrinking when the database is in use or is online in production?
3)Will the shrinking of the logfile improve the performance in any manner like that of the i/o operations or paging?
4)Can I do the shrinking of the log files alone without the shrinking of the corresponding data files?
I am using Sql Server 2012 in always on configuration with multi subnet failover clustering. Size of data file has suddenly increased, i dropped all the unnecessary table from database three days back. day before yesterday i tried shrinking data file using DBCCÂ command but it is taking too much time. is there any other option for deallocating the space.
I have a database which has log file size 300 GB. As the drive is filling up i need to clear the space on the drive, for that i have to shrink the log file.Â
Unfortunately i dont have option to take backup of the database.And i am not able to shrink the file now. Is there any way to shrink the log file with out taking backup of it ?

I am working on a client product that shrinks the database in MS SqlServer. After shrinking the database files, it does not send any email notification to the users.
My question is: Is there any way in SqlServer to sense that the database has been shrunk and send a notification to the users (may be through an Alert or a Job or something). Please let me know the steps to do that.
When I am trying to shrink a database, I got the following error.

Hi all.I'm having trouble shrinking a database. In short, using the SQL QueryAnalyzer,I enter the following commands:DBCC SHRINKDATABASE (database, 80)GOThe command returns the expected 'DBCC execution completed.' response, butthe databaseremains the same size when I run 'sp_helpdb database'. Am I missingsomething?Thanks in advance,Jaeger
I use management studio on the sql server. Each time i want to run scripts over new data, i have to delete the old files in a database and import new ones (from csv files to .dbo). These are the same files everytime except that the data change. Is it possible to make an automated proces for this import?
Can anyone help, I have a master database on my server which has an extremely large log file size. I need to shrink this down and so I have tried using dbcc shrinkfile (master, 50, truncateonly) and dbcc shrinkdatabase although it does not seem to reduce in size
I've read lots about why you shouldn't normally shrink databases in posts such as this:
[URL]
But we have a situation where we are required to copy the live db to various non production environments for testing. Part of this process involves truncating a number of tables with masses of blob data. So we're freeing up quite a lot of space. The question is how to reclaim this? The database is peculiar in that it's got no clustered indexes so I can't rebuild indexes on another filegroup with drop to move and rebuild.
I've tried dbcc shrinkfile specifying a size. I've tried to shrink the file in increments. The problem is I'm just not getting much space released. I get maybe 2-3%. I suspect this is because we're dealing with heaps with some tables that have sparsely populated blob / image data.
Is there an alternative to shrinking? Should I recreate all the db objects in a new database? It doesn't matter if the process takes a while or if it has to be done manually.
Hello,I am trying to clean up a database I inherited.I have an 80GB SQL 2000 database with 20 datafiles each 4096 in size. Ihave been able to remove unneeded data and am now trying to clean up.If I do a Shrink on each datafile would able to recover on average 2gbout of 4g, however I would prefer to have 10 full datafiles and 10empty. (or better yet 5 full 8GB datafiles and 15 empty)Can someone point me in the right direction on how to move the dataaround so that dont have 20 partially filled datafiles?I have noticed that I can shrink a single file and use the "empty thefile option (and move data to other files in the group)." option. Ihave already done this to the last 2 datafiles as a test but not surehow to do this on a large scale. I have also set the 1st 10 datafilesto be able to grow to 8 GB.For lack of a better way to say this, Is there a way to defrag orreorganize the data ables so everything "moves to the front".BTW, I have already run a maintenance plan to reorganize the data andindex pages.
I have a large (420GB) database that has never had data archived off before. I taken a backup to a test server and run a script supplied by the product vendor which has removed a large ammount of old data no longer required.
I have checked within enterprise manager that this data has now gone, however the actual file itself has not shrunk in size. Is there a further step I need to take to get back the space.
I have just finished configuring my first test mirrored environment (High safety mode). I setup the database engine service accounts on each of the servers with domainuser. I inherited a production mirrored environment set up by someone else. On the production servers the database engine service account is NT Authorityuser a local account. I am trying to practice installing Windows updates within a mirrored environment and I not sure how to proceed when the service account is NT Authority user account. should I change the service account to a domainuser?
