Hi ,
Last week[Thursday] the d size is arround 30 GB. But today i wondered the database size is around 47 GB .
Can you please let me know what are the causes to increase the database size??
I am sure on weekends there is no scope to insert these much data[around 17 GB]?
Thanks

Any weekend maintenance job like index rebuild?

Do you have any weekend processes like rebuild, reorganise indexes etc?
What is the autogrowth setting of the DB in question?
Do you keep a record of the space used on a daily basis?
The below will loop through each DB and show you free space, used space, total space.
DECLARE @sql NVARCHAR(MAX)
SELECT @sql = REPLACE(
CAST(
(
SELECT 'USE ' + QUOTENAME(name) +';' + CHAR(13) + CHAR(10) +
'SELECT ' + CHAR(13) + CHAR(10) +
'DatabaseName = DB_NAME(), ' + CHAR(13) + CHAR(10) +
'a.FILEID, ' + CHAR(13) + CHAR(10) +
'[FILE_SIZE_MB] = CONVERT(DECIMAL(12, 2), ROUND(a.size / 128.000, 2)), ' + CHAR(13) + CHAR(10) +
'[SPACE_USED_MB] = CONVERT(DECIMAL(12, 2), ROUND(fileproperty(a.NAME, ' + CHAR(39) + 'SpaceUsed' + CHAR(39) +') / 128.000, 2)), ' + CHAR(13) + CHAR(10) +
'[FREE_SPACE_MB] = CONVERT(DECIMAL(12, 2), ROUND((a.size - fileproperty(a.NAME, ' + CHAR(39) + 'SpaceUsed' + CHAR(39) +')) / 128.000, 2)), ' + CHAR(13) + CHAR(10) +
'a.NAME, a.FILENAME ' + CHAR(13) + CHAR(10) +
'FROM dbo.sysfiles a;' + CHAR(13) + CHAR(10)
FROM sys.databases
FOR XML PATH('')
)
AS NVARCHAR(MAX)
),
' ',CHAR(13) + CHAR(10)
)
--SELECT @sql
EXECUTE sp_executesql @sql

The database is in simple recover model but the mdf file size is 32 Gb and ldf file size is 15 gb .I try to shrink the file but no free space there . How can i reduce the log file size?
Thanks

I would recommend reading this http://www.sqlservercentral.com/articles/Administration/64582/ before you do anything.
If the log file jumped to that size, it was for a reason and would probably do it again.
As detailed already, do you have any maintenance jobs set to do anything to indexes etc?

Antony,
we have 2 servers one server is updating some data into another.
within SET XACT_ABORT on and off.
after this job added we have tremendous increase in log file growth with just max 20 - 30 records insert and update in 3 tables.
there is no significance growth in table size but why the log is growing in that manner.
i cannot remove SET XACT_ABORT on and off as it has to update the primary server also.

Well something needed that space, if you dont know what then I would recommend tracing the server, but if it only happens once in a blue moon then unless you had something logging what was going on, you will be hard pressed to see what caused it.
As a long shot you could try looking in the default trace, if your server has a fairly low usage and the trace events havn't been purged
http://www.sqlservercentral.com/articles/SQL+Server+2005/64547/
Would tell you when the log file grew, so you could try and pin point it to a process.

thanks and i'll read what you have given and comback incase needed.

Wowza
You have a DTC transaction which is still active since the 30th July, I would investigate that as top priority.
May also want to google "killing a negative spid" as you might find the transaction jumps to SPID a negative SPID when stopping the transaction.
August 6, 2012 at 4:11 am
How can we find out which transaction was running still 30 th july ??
Can we please provide the update asap .......
August 6, 2012 at 4:15 am
You have all the information you need in DBCC OPENTRAN, it gives you the SPID, so all you need to do now is query the DMV's to find out what the transaction is doing and where it came from etc.
August 6, 2012 at 4:38 am
I spid is looks different 1236s. Can you provide some DMVs to find the Querys which is causing this
August 6, 2012 at 4:43 am
try this i use this to see any block or not.
SELECT
s.spid, login_time, status,case when blocked = '0' then '' else convert(varchar,blocked) end 'blocked',text, hostname,ObjectName = OBJECT_NAME(objectid,s.dbid),
cpu , waittime, physical_io,
DatabaseName = DB_NAME(s.dbid),
s.program_name, s.loginame, cmd
FROM sys.sysprocesses s
CROSS APPLY sys.dm_exec_sql_text (sql_handle)
WHERE s.spid > 50
order by login_time
