DBCC Srhinkfile Didn't Shrink The File But Expand The Database Instead!!
Apr 6, 2001
I have a 2.8G SQL 7 database with 1.6G used space. I want to shrink it to 1.8G, but after I issued the 'DBCC srhinkfile(datafile, 1800)', it didn't shrink the file, instead it expanded to 2.7G used space? I tried on a test server, the command worked every time although the time to complete the task tended to increase every time.
I did the DBCC DBREINDEX (fill factor 90) and updated usage, the size didn't change. DBCC CHECKDB, CATELOG AND SHOWCONTIG were all performed and there wasn't any error or fragmentation.
Now I'm wondering what's the actual size of my database, 1.6G or 2.7G? If there's a way that I can get back close to my original used sized, then I can try to shink the file again. Any comment is welcome. Thanks advance.

Morning,
Is there a specific command/clause in the DBCC SHRINKDATABASE command where I can force a database to release free space to the operating system ?
Cheers,
Duncan

I've already shrunk the tlog from 350 GB to 313.My DB Server (2008 R2 Sp2) cannot be restarted and the db cannot go offline or detach due to company policy.My DB after changing from full to simple mode still has 313GB tlog file and when I run DBCC OPENTRAN I get Transaction information for database 'DB'.
Replicated Transaction Information:
Oldest distributed LSN : (0:0:0)
Oldest non-distributed LSN : (2882:26:1)
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
Which means this DB is participating in a High Availability process like replication, mirroring or log shipping.
So I run EXEC sp_repldone @xactid = NULL, @xact_segno = NULL, @numtrans = 0, @time = 0, @reset = 1.
This is useful when there are replicated transactions in the transaction log that are no longer valid and you want to truncate the log.
But I get an error:
Msg 18757, Level 16, State 1, Procedure sp_repldone, Line 1
Unable to execute procedure. The database is not published. Execute the procedure in a database that is published for replication.
There are currently 9 connections and all are sleeping.What else can i try in order to shrink the tlog file?

Hi guys
when we do manual Database shrink at normal office hours does it make any issues
or best way to control it
1. Does it lock database and runs the shrink statement.
2. at time of shrink users allowed or not.
3. transactions can be committed.

I'm running full recovery mode and doing log shipping so changing to simple mode is not an option.
I'm running BACKUP LOG right before and when I check it says my log is 99% free (on a 180GB log).
When I do DBCC LOGINFO('dbname') right before and after I see a dozen entries and they are all over the file and not just at the starting offset areas. The BACKUP LOG doesn't clean out the file completely.
Is there any explanation for this? Even though I'm doing this at off hours, is it possible that someone on the site in that split second is putting new entries in the log? Why are they spread out though? If they just put entries at the beginning I could shrink the file to a normal size still.

In SQL 2005, when a file is expanded because of the auto expand option turned on, is this recorded anywhere (each time it expands)?

In SSMS, I connect Object Explorer to a partially contained database using a contained user login with password. This user has a database role of dbdatareader. When I try to expand the Tables in the database, I get the error:
The SELECT permission was denied on the object 'extended_properties', database 'mssqlsystemresource', schema 'sys'. (Microsoft SQL Server, Error: 229)
Is there a way to set permissions for the contained user so that this could be done?

Hi,
I need to expand tempdb database. The users keep getting this error
when they try to do a sort:
SQL Server message(1510): state 2
Sort failed. Out of space or locks in database 'tempdb'
Also in the error log I am getting these errors:
Error 1105, Severity: 17, State: 1
Can't allocate space for object '-641' in database 'tempdb'because
the 'system' segment is full. If you ran out of space in Syslogs, dump the
transaction log. Otherwise use ALTER DATABASE or sp_extendsegment to
increase the size of the segment.
What I am wondering is if expanding tempdb will fix the problem, or is
there another fix that I should be looking at.
Any direction you could give me on this would be appreciated. I have very
little experience with SQL 6.5
Thanks in advance

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

We have a person who CAN connect to a named instance in SQL Server Management Studio. There is nothing in the log for a failed login for him. However, when he tries to expand the Tables folder under the only user database in the instance, he gets the error: Failed to retrieve data for this request (Microsoft.SQLServer.SmoEnum). Additional Information: An exception occured while executing a Transact-SQL statement or batch. Select permission denied on object 'extended_properties',database 'mssqlsystemresource', schema 'sys'(Microsoft SQL Server, Error:229).
He is trying to expand the Tables folder under a database named ADSALLDB. He can see the folder as well as the other folders (i.e. Views, Synonyms, Programmability,etc.), but can't expand any of them. He can expand the folders under the system databases.
Other uses set up just like him can connect. He is set up with read/write access to the database ADSALLDB. He can expand the system databases.
This is a named instance in a 6 node cluster. SQL Server 2005 SP1 Build Level 2221.
Thank you for any help.

Has anyone had an issue with SQL Server not being able to expandagainst a RAID 5 file system? My current configuration is that theserver is started and stopped using the local system account. I haveonly one database (besides the master, model,etc)on the server. Whathas happend to me several times is that the primary database inquestion try's to expand the main datafile for the database (.mdf). Isetup the database to not expand automatically initially so that I canbe sure that we have enough file system space. Becuase of problems withthe application I decided to automatically expand. The other day thedevelopers came to me indicating that the databse was full and neededto be expanded. Knowing that the database was in automatic expandingmore I was surprise to hear this. I went into EM and attempted toexpand first the log and it would not indicating that it there was anissue in attempting to do so. I have never heard of a database notbeing able to expand. I ran DBCC's, etc and it came up clean. I triedto back the database up to disk and it would not backup. I finally hadto rename the datbase and rebuild it using DTS and scripts. I thoughtI had fixed it only to find out today that it (again) won't expand. Irenamed the datbase and then tried taking an older backup file andrestore it and it would not restore. This problem seems to be relatedto the file system but how I do not know.So, I am ready to run rebuild master but I have sone this before onlyto have this come back on me. I am at a complete loss. In the past Ihave had to rebuild the entire server and database from scratch. Theonly problem is that this has been done 3 times now with no completesolution or explaination. If any of you have seen this type ofbehavior and know whats going on please, please let me know what youthink the case and solution is!

In my environment, there is maintenance plan configured on one of the server and while running DBCC checkdb on a database of size around 200GB, log file usage of tempdb is increasing and causing the maintenance job to fail.
What can I do to make the maintenance job run successfully, size of the tempdb database is only 50GB and recovery model is set to simple. It cannot be increased as the mount point on which it is residing is 50GB.

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

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

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.

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??
Thanks

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?

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

First off, I'm normally not one to shrink the hell out of data files (for obvious reasons), but this is a special case. We are setting up a mini test environment in preparation for migrating one of our systems to SQL Server 2005 (among other things).
The problem I have is that the test SQL Server I have to use has only about 50GB of disk space that I can allocate to databases, when the databases that I need to fit in there sit at around 130GB total. I've got 13 total databases that I have to fit in there. There are several logging tables in each, and lots of binary data that's really not needed for our testing. The first thing I did on my testing copies was to change the recovery model to simple, which chopped the log file.
So I've been truncating the logging tables and have been stripping out the unneeded data. I then have been running a script that I wrote to reindex, then shrink the individual files, then the database as a whole. Probably overkill, but it has worked on all of the DBs with the exception of one.
This particular DB is approx 21GB in total size (it's already come down from about 55GB), but when you look at the free space, it's showing 75% free inside the mdf file. I don't really care much about performance at this point, I just need to get the file size down and can't figure out how.
Any ideas?
BTW - this is the script that I wrote:
declare @tablename varchar(255)
declare @logfilename nvarchar(200)
declare @datafilename nvarchar(200)
declare @dbname nvarchar(200)
declare @sql nvarchar(1000)
set @dbname = ltrim(rtrim(db_name()))
set @logfilename = ltrim(rtrim((select name from sysfiles where lower(filename) like '%.ldf%')))
set @datafilename = ltrim(rtrim((select name from sysfiles where lower(filename) like '%.mdf%')))
/* Reindex Tables */
declare tablecursor cursor for
select '[' + table_schema + '].[' + table_name + ']' from information_schema.tables
where table_type = 'base table'
open tablecursor
fetch next from tablecursor into @tablename
while @@fetch_status = 0
begin
print 'Reindexing ' + @tablename
dbcc dbreindex(@tablename,' ',90)
fetch next from tablecursor into @tablename
end
close tablecursor
deallocate tablecursor
/*Shrink the crap out of the DB*/
set @sql = 'BACKUP LOG [' + @dbname + '] WITH TRUNCATE_ONLY'
print @sql
exec sp_executesql @sql
set @sql = 'DBCC SHRINKFILE([' + @logfilename + '], 1)'
print @sql
exec sp_executesql @sql
set @sql = 'DBCC SHRINKFILE([' + @datafilename + '], 1)'
print @sql
exec sp_executesql @sql
set @sql = 'DBCC SHRINKDATABASE([' + @dbname + '], 1)'
print @sql
exec sp_executesql @sql

Why shrinkfile empty file does not redistribute data evenly in the primary file group with multiple files:
Please run the script attached to see what the end result is.
This is what I set up last night on my test machine.
1) Create database [FGTest] size 200MB
2) Create table called TEST on primary
3) Insert 40MB of data into test
4) Create another file group called temp in primary size 200MB
5) Shrinkfile('FGTest',emptyfile) so that all data is transfered from FGTest into temp file group.
6) Add another 2 files called DATA2 and DATA3. Both are 200MB.
7) We now have 3 empty files that I want data distributed evenly on. FGTest, DATA2 & DATA3
8) Shrinkfile('temp',emptyfile) to move all the data from temp over the 3 file groups evenly
I would expect at this stage to have the following:
FGTest = 13MB,
DATA2 = 13MB,
DATA3 = 13MB
(40MB of data over 3 files should be about 13 MBish in each file)
What I actually end up with is this:
FGTest = 20MB
DATA1 = 10MB
DATA2 = 10MB
It looks as though SQL Server is allocating 50% of all data to the original file and then 50% evenly over
the remaining files in PRIMARY.

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.

Hi, I am trying to automate shrinking the transaction log file on SQL server.
Every so often we get errors with our application using SQL server, in which I resolve by running the backup log and shrink log commands. However, recently I got the error: Could not allocate space for object 'table_name' in database 'database_name' because the 'Primary' file group is full. To resolve this I had to create another transaction log and then run the backup log and shrink log commands.
I know need to automate the process of shrinking the log file. I have checked and the Auto Shrink checkbox is ticked but these errors still occur.
How can I delete the additional log file I created and automate this task of shrinking the log file within SQL server? Any help would be appreciated...Thanks

i have a log file for a 200 meg database that is now over 80gigs. It is way out of control but DBCC shrink file just reports... the file is not part of a replication set.
Cannot shrink log file 2 (Database_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.
I have read around and seen the suggestion to make a new database file and copy all the data to it. How is that done? I am using SQL 2005 Express with microsoft SQL server management Studio express.
