SQL Server 2008 shirnk logs

  • Does anyone have any script or stored procedure to shrink all the databases in sql server 2008.

    Please let me know if you have it.

    I have this below script and will not work for sql server 2008.

    CREATE PROCEDURE SP_SHRINK_LOG

    AS

    BEGIN

    DECLARE dbNames_cursor CURSOR

    --

    -- Run this script routinely to control the growth of LDF log files.

    --

    FOR

    SELECT NAME FROM dbo.sysdatabases where name not in ('master', 'model', 'msdb', 'tempdb')

    OPEN dbNames_cursor

    DECLARE @dbName nvarchar(50)

    FETCH NEXT FROM dbNames_cursor INTO @dbName

    WHILE (@@FETCH_STATUS <> -1)

    BEGIN

    IF (@@FETCH_STATUS <> -2)

    BEGIN

    declare @logName nvarchar(50)

    exec(' use [' + @dbName + '] ' + 'backup log [' + @dbName + '] with truncate_only')

    set @logName = @dbName + '_log'

    exec(' use [' + @dbName + '] ' + 'declare @logName nvarchar(50) select @logName = name from sysfiles where fileid = 2 set @logName = rtrim(@logName) dbcc shrinkfile (@logName)')

    dbcc Shrinkdatabase (@dbName, 0)

    END

    FETCH NEXT FROM dbNames_cursor INTO @dbName

    END

    CLOSE dbNames_cursor

    DEALLOCATE dbNames_cursor

    END

  • Good thing it doesn't work.

    The command you need to run is backup log. Not truncate log.

    If you don't care about losing all the data between full backups change the dbs to simple mode.

    Edit : And read this one too

  • Backup log with truncate_only is not supported with SQL Server 2008. I have to say that I wouldn’t run this script on other versions that still support the truncate_only option. Running such script breaks the log backup chain for all databases and forces you to run full backup on all databases if you still want to use log backups (and have the ability to restore a database to a point of time).

  • so this will work right. And after running this I always run full backups anyways.

    CREATE PROCEDURE SP_SHRINK_LOG

    AS

    BEGIN

    DECLARE dbNames_cursor CURSOR

    --

    -- Run this script routinely to control the growth of LDF log files.

    --

    FOR

    SELECT NAME FROM dbo.sysdatabases where name not in ('master', 'model', 'msdb', 'tempdb')

    OPEN dbNames_cursor

    DECLARE @dbName nvarchar(50)

    FETCH NEXT FROM dbNames_cursor INTO @dbName

    WHILE (@@FETCH_STATUS <> -1)

    BEGIN

    IF (@@FETCH_STATUS <> -2)

    BEGIN

    declare @logName nvarchar(50)

    exec(' use [' + @dbName + '] ' + 'backup log [' + @dbName + '] with backup_log')

    set @logName = @dbName + '_log'

    exec(' use [' + @dbName + '] ' + 'declare @logName nvarchar(50) select @logName = name from sysfiles where fileid = 2 set @logName = rtrim(@logName) dbcc shrinkfile (@logName)')

    dbcc Shrinkdatabase (@dbName, 0)

    END

    FETCH NEXT FROM dbNames_cursor INTO @dbName

    END

    CLOSE dbNames_cursor

    DEALLOCATE dbNames_cursor

    END

  • If you want to destroy your server, a shotgun approach is much faster and cheaper. Especially more fun.

    Last time I say this, read the articles we linked to.

  • No. It won't (there's no backup_log option on Backup Log)

    Please go and read my article and stop shrinking your database
