Good script.

I had to change 3 things to make it work:

1. Insted of execute (@Query) corrected it to PRINT @Query, cause I wanted to check the script before running

2. Corrected USE ''?'' to USE [?] having to deal with the SharePoint databases with dashes in their names

3. Change the following line:

From:

CREATE TABLE ##Fdetails (Dbname VARCHAR(50),Filename VARCHAR(50),Autogrow_Value VARCHAR(15),Max_Size VARCHAR(30))

To:

CREATE TABLE ##Fdetails (Dbname SYSNAME,Filename VARCHAR(128),Autogrow_Value VARCHAR(15),Max_Size VARCHAR(30))

as the SherePoint databases names and filenames did not fit in.

Looks good otherwise.

Thanks.

Thanks for this script!

I changed it a bit for my use:

- using a table variable instead of a 'real' table

- use dynamic autogrow-settings depending on the size of the db-file

- use the sys.master_files table instead of the depricated sysaltfiles table

- removed the cursor

- view the script without executing it directly

DECLARE @ConfigAutoGrowth as table

(

iDBID INT,

sDBName SYSNAME,

vFileName VARCHAR(max),

vGrowthOption VARCHAR(12),

vgrowth bigint ,

vsize bigint,

cmd varchar(max)

)

-- Inserting data into staging table

INSERT INTO @ConfigAutoGrowth

SELECT

SD.database_id,

SD.name,

SF.name,

CASE is_percent_growth

WHEN 1

THEN 'Percentage'

WHEN 0 THEN 'MB'

END AS 'GROWTH Option',

case when is_percent_growth =1 then growth else growth*8/1024 end,

size *8/1024 ,

''

FROM sys.master_files SF

INNER JOIN

SYS.DATABASES SD

ON

SD.database_id = SF.database_id

--Change value increments, non-percentage growths

UPDATE @configautogrowth

SET cmd =

CASE

WHEN vsize < 300 AND vGrowth <> 50 THEN 'ALTER DATABASE '+ sDBName +' MODIFY FILE (NAME = '+vFileName+',FILEGROWTH = 50MB)'

WHEN vsize BETWEEN 300 and 1000 AND vGrowth <> 100 THEN 'ALTER DATABASE '+ sDBName +' MODIFY FILE (NAME = '+vFileName+',FILEGROWTH = 100MB)'

WHEN vsize BETWEEN 1000 and 2000 AND vGrowth <> 200 THEN 'ALTER DATABASE '+ sDBName +' MODIFY FILE (NAME = '+vFileName+',FILEGROWTH = 200MB)'

WHEN vsize > 2000 AND vGrowth <> 400 THEN 'ALTER DATABASE '+ sDBName +' MODIFY FILE (NAME = '+vFileName+',FILEGROWTH = 400MB)'

END

WHERE 1=1

--and sdbname NOT IN ( 'master' ,'msdb' )

AND vGrowthOption ='MB'

-- Change percentage-growths

UPDATE @configautogrowth

SET cmd =

CASE

WHEN vsize < 300 THEN 'ALTER DATABASE '+ sDBName +' MODIFY FILE (NAME = '+vFileName+',FILEGROWTH = 50MB)'

WHEN vsize BETWEEN 300 and 1000 THEN 'ALTER DATABASE '+ sDBName +' MODIFY FILE (NAME = '+vFileName+',FILEGROWTH = 100MB)'

WHEN vsize BETWEEN 1000 and 2000 THEN 'ALTER DATABASE '+ sDBName +' MODIFY FILE (NAME = '+vFileName+',FILEGROWTH = 200MB)'

WHEN vsize > 2000 THEN 'ALTER DATABASE '+ sDBName +' MODIFY FILE (NAME = '+vFileName+',FILEGROWTH = 400MB)'

END

WHERE 1=1

AND vGrowthOption ='Percentage'

--show ALTER-statements

SELECT cmd FROM @configautogrowth

where cmd is not null

GO

I hope this will help someone.....

Anja, your script is really helpful! I'm working on fixing the autogrowth settings on our servers and your script is very helpful. It's a good script because it's using current system views instead of deprecated ones.

Thanks!
