The Windows SharePoint Services 3.0 (WSS) log file may grow to a large size on a default installation of Windows Small Business Server 2008 (Windows SBS). The Windows SBS Best Practices Analyzer (BPA) reports the following warning message:


Sharepoint Config database log file getting large

The Windows SharePoint Services configuration databases log file is getting large (currently over 1gb in size)



This will occur if the database is configured to use the default setting of full recovery mode and numerous transactions have been logged to the database.


To reduce the size of the log file, follow these steps. 

Note It's a good idea to do a full server backup before you complete these steps.

We can help you reduce the size of the log file. To do this, go to the "Fix it for me" section. If you prefer to fix this problem yourself, go to the "Let me fix it myself" section.

1. Start Notepad. To do this, click Start, point to All Programs, point to Accessories, and then click Notepad.

2. Copy and paste the following text into Notepad. Save the file as c:\logshrink.sql

declare @ConfigDB varchar(255);
declare @ConfigDBLog varchar(255);
declare @ConfigDBCmd varchar(255);
select @ConfigDB = name from sys.databases where name like 'SharePoint_Config_%';
set @ConfigDBCmd = 'BACKUP database [' + RTRIM(@ConfigDB) + '] to disk=''C:\windows\temp\before.bkf''';
set @ConfigDBCmd = 'use [' + RTRIM(@COnfigDB) + ']';
set @ConfigDBCmd = 'BACKUP LOG [' + RTRIM(@ConfigDB) + '] WITH TRUNCATE_ONLY';
set @ConfigDBCmd = 'use [' + RTRIM(@COnfigDB) + ']';
select @ConfigDBLog = name from sys.database_files where name like 'SharePoint_Config%_log';
set @ConfigDBCmd = 'use [' + RTRIM(@ConfigDB) + '] DBCC SHRINKFILE([' + RTRIM(@ConfigDB) + '_log],1)';
set @ConfigDBCmd = 'BACKUP database [' + RTRIM(@ConfigDB) + '] to disk=''C:\windows\temp\after.bkf''';

3. Open an elevated command prompt. To do this, follow these steps:

  1. Click Start, click All Programs, click Accessories, and then right-click Command Prompt.
  2. Click Run as administrator.  Note If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.

4. At the command prompt, copy and paste (or type) the following command, and then press Enter:

sqlcmd -S \\.\pipe\mssql$microsoft##ssee\sql\query -E -i c:\logshrink.sql 

Note This script creates two backup files (before.bkf and after.bkf) in C:\windows\temp.
