Having just archived quite a bit of data from the main Production DB, I now have around 15% free, reclaimable space sat in the data file.
I'm reluctant to run DBCC SHRINKFILE as that apparently causes a lot of Index fragmentation which will cause issues for performance - how else can the space be allocated back to the OS?
I have a tempdb split into 4 files (5 if you include the log).
Autogrowth is disabled on the mdf/ndf files so that they can be used round robin (1 file per logical CPU).
Is there a way to be alerted when there is x% of free space left?
I know hwo to check the free space via t-sql but want to be able to be alerted. I could run a sql job that reports the free space and send a database mail message if under x% but wondered if there was a built in (or better) method?
I also have SQL Sentry.
SQL 2012 Standard
Recently maintenance was done removing some tables from the original filegroup in one drive of our SQL Server 2012 Standard Edition 64bits to another created on a separate physical drive. I was expecting the full amount of data moved to the secondary filegroup to show up as unused on the primary filegroup but that doesn't seem to be the case. Do I have to do anything after the move to release that space, not to disk, but to the database as unused?
View 2 Replies View RelatedI'm running a security application that generates a lot of events. I have gone in over the past couple days and deleted large numbers of old events in an effort to reclaim space on the D: drive where the SQL DB for this app resides. I did this throught the app itself... through its GUI front end.
I'm not having any impact. There is not a file on the same drive where the deleted events are being directed to. If all these events are going away, why does my used space on the drive not shrink? I came at it from another tack, creating sql queries to delete old events from the same app. I did this through queries in the SQL mgmt studio. The tasks (multiple) completed successfully, and the report on the # of rows 'affected' showed that it was a substantial number. No decrease in the windows drive space being used. Any tips?
Dear Friends,I'm running a SQL 2005 database. Lately (in the last 4 months) my database size has grown exponentially and now totals 2.5 gig (it used to be about 100mb). When I run sp_spaceused i get the following info:
Reserved Space 2522MB
Data 450MB
Indexes 215MB
Unused 1856MB
<!--[if !supportLineBreakNewLine]-->
The unused space is reserved by my two largest tables, one being 542mb (which is a log I create and the size seems fine for the amount of data) reserving 1033mb and the other being 121mb (which is another log and also seems fine) reserving most of the rest.
I have tried running DBCC SHRINKFILE and DBCC CLEANTABLE commands on a backup copy of the database and cannot seem to free the unused space.
I have also tried copying the database in an attempt to reduce the unused reserved space and have tried creating a new database and importing the tables with no luck
Any help would be greatly appreciated, noting that I'm honestly not that technical and would probably need step by step instructions, but if you only have time to point me in the right direction that would also be of great help!

I'm trying to figure out how to reclaim unused space in a huge table (tbl) after setting one of the text columns to be the empty string. Other tables have foreign key columns associated with tbl.
After doing something like this,
update tbl set col = ''
the table doesn't automatically reclaim that space. If I do a direct insert into a new table like this,
insert into tbl2 (cola, colb, colc) select * from tbl
the new table is smaller as expected (about half the size in my case). Any ideas?

I have many large tables with millions of records in a SQL Server database. They all use an Identity column which is the clustered index. We haven't been deleting any records until recently because disk space is now becoming a problem.
Assuming I delete a lot of old records, I'm thinking that the freed up space in the data pages won't be reused. New records will be added at the end of the table because of the Identity column being the clustered index. So the table will keep getting bigger even though there is lots of free space.
Assuming I'm right, then how do I recapture this unused space? Is an alter table rebuild the best way? Or rebuilding the clustered index?
Hi,
I have to rebuild a clustered index.I want to know how to find out the free space in a database ?
I know that DBCC SQLPERF ( LOGSPACE )
will give free space in a log space.
Thanks,

I inherited a SQL server (2005) that sits on a Windows 2003 box (upgrading to 2008 R2 and Win2008, ASAP) and on our SQL Data Drive (260GB - 22GB free) we have 16 databases (that are associated with our primary application). One database in particular is causing me quite a bit of pain - on Tuesdays. This table will consume all available free space (save 700kb) and place it within it's 'reserved' space. It's not being used and I can reclaim it by shrinking. I have done this for 3 consecutive weeks now and I have always thought that shrinking is not really a best practice.
Based on a job I scheduled to spit out various database stats I discovered the following:
Somewhere after 11pm on Monday (and on or before 11:30pm) the reserved space goes from 9GB down to 23 then 37MB on this particular database.
After 1:30am on Tuesday (and on or before 2:00am) the database consumes nearly all available disk space and thus expands its reserved space to 28GB
I believe it has something to do with the Indexes being rebuilt - per the Maintenance Plan the Index Rebuild is supposed to occur every Monday @ 11pm. On 6/18 it ran from 11pm - 11:44pm with no problems. Starting on 6/26 (and subsequently 7/2 and 7/9) they have started at 11 and ended anywhere between 2 - to 3 hours later. And with the following error:
Failed-1073548784) Executing the query "ALTER INDEX [PK_activityLog] ON [dbo].[activityLog] REBUILD WITH ( PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, SORT_IN_TEMPDB = OFF, ONLINE = OFF ) " failed with the following error: "Could not allocate a new page for database 'FA_PROD_SDDS' because of insufficient disk space in filegroup 'PRIMARY'.
Create the necessary space by dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. The statement has been terminated.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
The database 'FA_PROD_SDSS' is the one that I am having issues with.
Hi all
Iam working in Prodcution ENV,Please help how make space
The log file for database 'Home_alone' is full. Back up the transaction log for the database to free up some log space.
hello everyone,
I have a question about the under what circumstances will a large database with mostly free space not shrink?
thanks
Dear friends
I need to report the amount of free space in each datafile of a database.
I have tried sys.dm_db_file_space_usage , but the documentation says that it only works for the TempDB.
Please help.

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.
I have about 50 databases that are only accessed once a month and on a predictable schedule. Would it free up resources on the server if they were kept offline and brought online only when needed ?

Hi All,
I was wondering if anybody has the script to view the free disc space. Currently I am using xp_fixeddrives stored procedure, but it is undocumented and might not be supported in SQL Server 2005.
Thanks.
I would like to know how to determine how big log and data space is, and how much of this space is free. I would like to create a script to warn me when less than 20% free space is left in log as well as data.

I've gone through the forum and have seen several others with a similar situation. I recently noticed my .mdf file grew to 200GB yet the data in the file is only about 40GB. I run sp_spaceused and get the following: database_size = 176GB, unallocated space = 134GB, reserved = 43GB, data = 17GB, index_size = 19GB, unused = 6GB.
I've tried "dbcc shrinkdatabase (mydb, truncateonly)", tried restarting server, tried running a maintenance plan including a reindex of the database, and I don't know what to do next.
Does anyone know how to free up this space?
Hi:
How can i get the Total and Free space of my filegroups, do you have some script for that?
Thnaks :eek:
Hi,
While I am importing few data to my SQL Server (2000) database, the free space is gettig increased in GBs. The database's File Growth is 1 MB (same for both Data Files and Transaction Files). The same database I restored on another PC and did the same process, it is working fine as there is no enormous growth in Free Space.
Any idea why this is

I was just reading a doc on SQL , that said that to free up the unused space from the DB , you should use the shrinkdatabase DBCC commnad. ....

My disk drive was full. So I deleted some records. Then I tried to shrink and it indicated available free space of around 5GB as indicated in the below image.
Once I ran the shrink for data file, though it completed successfully I didn't get the 5GB space as indicated. For log file shrink it shows available space of 200MB and when I run a log file shrink it does free up 200MB as indicated. So why is it not working with data file shrink? What am I doing wrong?
Hi,
I have some space available in the database, I tried dbcc shrink database and srrink file. I am not getting the disk space. But the amount of free space on the database sometime get increased.

Hi friends ,
I have a database with around 2 GB space for the data and 5.8 GB for the
transaction log .
Now the problem is i do not have any more space on the system and data files requires more space than 2 G.B to execute some stored procedures .
Is it possible to decrease some space of the transaction log , say from 5.8 GB to 2 GB and allocate it to the data files .
My data and log files are on different drives . I did not find anything related to this topic in the BOL .
Can somebody help me with this problem ? Anthing related to this issue will be of great help to me since i have no expertise in this field .
Thanks and Regards

what is the best way to make free space in tempdb?
View 5 Replies View RelatedHi,
In sql 7.0 , i would like to create a database with the size of 10Gb, in my server couple of databases already exist.
How do i know how much free space is there in File group.
we are having only one file group i.e PRIMARY.
Could anyone pls tell me about this.
Thank u.

does anyone know if tempdb can be physically moved to a different partition on a disk drive on SQL Server 7.0? Since it can't be backed up I'm hesitant to use the sp_detach/sp_attach procedure because I don't want to crash it. If nothing else is available, I can attempt moving it this way at the end of the day and then just reboot to get tempdb back up again if the server fails, but I'd really appreciate a suggestion from someone who has more know-how than I do about system table operations. Thanks again
View 1 Replies View RelatedI've faced with this problem in my DB:
There are some tables that suffer inserts and deletes daily. These tables have 3 nonclustered indexes including the pk.
I perceived that the space used for these tables are growing day after day even ocurring daily deletes.
These inserts and deletes follow the keys of the pk in ascent order.
I ran DBCC SHOWCONTIG on the tables and got results like this:
- Avg. Bytes Free per Page.....................: 7996.3
When I transform the pk to clustered this problem doesn't happen.
You realized the consequence of this: the users complains because the DB is without space, but it's not true!
Anybody could help me to understand why the extents are not being deallocated?
Thank's for help!
Hi all,
I have to find free disc space in a drive from SQL Query and i am using MSSQL200. Does any body know the command for the same.
Also if i want to find hard disk space of a different machine on network, it is possible to get the data??
Also can i get the CPU/Memory usage data of our machine by some SQL/C++ commands??
Please let me know if u know any of the answer...
