Shrink All Log Files Within A MS SQL Instance

stewart — Wed, 07 Apr 2010 11:58:09 +0000

This little SQL script is used to to shrink all the log files in a Microsoft SQL server instance. It uses the following function to get the job done: DBCC SHRINKFILE.

declare @ssql nvarchar(4000)

set @ssql= '

        if ''?'' not in (''tempdb'',''master'',''model'',''msdb'') begin

        use [?]

        declare @tsql nvarchar(4000) set @tsql = ''''

        declare @iLogFile int

        declare LogFiles cursor for

        select fileid from sysfiles where  status & 0x40 = 0x40

        open LogFiles

        fetch next from LogFiles into @iLogFile

        while @@fetch_status = 0

        begin

          set @tsql = @tsql + ''DBCC SHRINKFILE(''+cast(@iLogFile as varchar(5))+'', 1) ''

          fetch next from LogFiles into @iLogFile

end

        set @tsql = @tsql + '' BACKUP LOG [?] WITH TRUNCATE_ONLY '' + @tsql

        --print @tsql

        exec(@tsql)

        close LogFiles

        DEALLOCATE LogFiles

        end'


exec sp_msforeachdb @ssql

A potentially dangerous Request.Form value

stewart — Thu, 07 Jan 2010 18:00:00 +0000

We were having trouble adding a user to a site collection. Every time we hit the search button or clicked the check userid button the system would just sit there and spin. I added the following section of the web.config to resolve the issue.

compilation>
  <pages enableSessionState="false" enableViewState="true" enableViewStateMac="true" validateRequest="false" pageParserFilterType="Microsoft.SharePoint.ApplicationRuntime.SPPageParserFilter, Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" asyncTimeout="7">
    <namespaces>
      <remove namespace="System.Web.UI.WebControls.WebParts" />
    namespaces>
    <tagMapping>
      <add tagType="System.Web.UI.WebControls.SqlDataSource, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" mappedTagType="Microsoft.SharePoint.WebControls.SPSqlDataSource, Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
    tagMapping>
  pages>
<siteMap defaultProvider="SPSiteMapProvider" enabled="true">

The error that we were getting in the trace logs is similar to below.

Exception Type: System.Web.HttpRequestValidationException  Exception Message: A potentially dangerous Request.Form value was detected from the client (ctl00$PlaceHolderDialogBodySection$ctl04$OriginalEntities="").
