Recovery Model: Simple
DB Size: 70 GB
Server Free Space: 145 GB
Every evening when we leave office LOG File is 20-30 GB or Less. But at midnight the log file size grows and takes all free space. The applications stops. In morning we shrink the log file down to 1 MB. All the day it works ok. We don’t run any process at midnight. Please advice how to handle the situation

Hi Pinal-
Actually I just wanted to know only the user database information. For that I just tweak your query a bit.
SELECT Distinct DB.name As DatabaseName,
DB.recovery_model,
mf.name as logical_name,
mf.physical_name,
(size*8)/1024 SizeMB
FROM sys.master_files mf
join sys.databases DB
on mf.database_id = DB.database_id
WHERE mf.database_id > 4
The reason I put WHERE mf.database_id > 4 is to get only user databases list.First 4 database_id’s are for system databases.

Can you provide me a query that will list all the DBnames that have log file size more than 10 GB?

Hi Pinal,

Putting new steps towards DBA very good script, Thank You.

Just quick question, The ‘growth’ field in ‘sys.master_files’ table, does it stamp date or time as well, like growth of the TestDatabase since this time ??

Thanks

Please prefer to use either sys.database_files or sys.sysfiles to get the db sizes. Try to avoid using sys.master_files dmv..

To answer why .. See the results below ..

USE tempdb
GO

SELECT SUM(SIZE)/128 FROM SYS.DATABASE_FILES;
– 29754 MB

SELECT SUM(SIZE)/128 FROM SYS.master_files
WHERE database_id = DB_ID(‘TEMPDB’)
– 18432 MB

If doing in ver. 8 (wait, what?), change database_id to dbid, and sys.master_files to master.dbo.sysaltfiles.

CREATE TABLE #f
(
name VARCHAR(255),
rows INT ,
reserved varchar(255),
data varchar(255),
index_size varchar(255),
unused varchar(255)
)

INSERT into #f

EXEC sp_MSForEachtable ‘sp_spaceused ”?”’

SELECT * FROM #f

DROP TABLE #f
// Hope this will help

This script is great. I am new to learning DBA role. Is the output for file size reflected in Kilobytes or Megabytes?

This list the files and sizes for all attached databases on server …

SELECT db.name AS [DB Name]
,dbf.[physical_name] AS [File Name]
,dbf.[size] AS [File Size]
,db.[create_date] AS [Create Date]
,ss.[Last User Event]
,ss.[Last User Update]
FROM sys.[databases] AS db
LEFT OUTER JOIN sys.[master_files] AS dbf ON [db].[database_id] = [dbf].[database_id]
LEFT OUTER JOIN (SELECT database_id,max(last_user_update) AS [Last User Update], ISNULL(ISNULL(max(last_user_update),max([last_user_seek])),max([last_user_lookup])) AS [Last User Event]
FROM sys.[dm_db_index_usage_stats] GROUP BY database_id) AS ss ON ss.[database_id] = db.[database_id]
ORDER BY db.[name],dbf.[physical_name]

And if you alter it just a little bit, you can have them summed by database:

SELECT DB_NAME(database_id) AS DatabaseName,
SUM((size*8)/1024) SizeMB
FROM sys.master_files
group by DB_NAME(database_id)
order by DB_NAME(database_id)

It’s not clear in my earlier comment, but the period at the end of my sentence is supposed to be a decimal point. Let me try again: “(size*8)/1024.0″.

By: Brass

Brass — Sat, 26 Mar 2011 05:53:58 +0000

You have some integer math up there. It should be: (size*8)/1024.
