DNN Clear Log

To clear the DNN Log from DB use the following scripts

TRUNCATE TABLE sitelog;

delete EventLog

where EventLog.LogGUID in (

SELECT el.LogGUID

FROM dbo.EventLog AS el LEFT OUTER JOIN

dbo.ExceptionEvents AS ee ON el.LogEventID = ee.LogEventID LEFT OUTER JOIN

dbo.Exceptions AS e ON el.ExceptionHash = e.ExceptionHash);

truncate table schedulehistory;

To shrink the DB (minimize the log file -.ldf- size) use the following script

ALTER DATABASE dbname SET RECOVERY simple; --To change the recovery model

DBCC SHRINKDATABASE (dbname, TRUNCATEONLY); -- shrink database

DBCC SHRINKDATABASE (dbname);

ALTER DATABASE dbname SET RECOVERY full; --To change the recovery model

OR use the following script

IF EXISTS (SELECT * FROM sys.sysobjects WHERE id = object_id(N'[sys_currentDNNVersion]') AND Type = N'FN')

DROP FUNCTION [sys_currentDNNVersion]

-- --------- create tooling: ---------

CREATE FUNCTION [sys_currentDNNVersion]()

RETURNS Int

BEGIN

DECLARE @Vers Int;

SELECT Top(1) @Vers = Major * 10000 + Minor * 100 + Build FROM [Version] ORDER BY CreatedDate DESC;

RETURN @Vers;

END

-- Drop Foreign Key Constraints:

DECLARE @fkName nVarChar(100) = Null;

SELECT @fkName = name FROM sys.foreign_keys

WHERE parent_object_id = OBJECT_ID(N'[ExceptionEvents]')

AND Object_id IN (SELECT constraint_object_id

FROM sys.foreign_key_columns F

JOIN sys.columns C ON F.parent_object_id = C.object_id AND F.parent_column_id = C.column_ID

WHERE C.Name = N'LogEventID');

IF Not @fkName Is Null

Exec(N'ALTER TABLE [ExceptionEvents] DROP CONSTRAINT [' + @fkName +'];');

SET @fkName = Null;

SELECT @fkName = name FROM sys.foreign_keys

WHERE parent_object_id = OBJECT_ID(N'[EventLog]')

AND Object_id IN (SELECT constraint_object_id

FROM sys.foreign_key_columns F

JOIN sys.columns C ON F.parent_object_id = C.object_id AND F.parent_column_id = C.column_ID

WHERE C.Name = N'ExceptionHash');

IF Not @fkName Is Null

Exec(N'ALTER TABLE [EventLog] DROP CONSTRAINT [' + @fkName +']')

-- Truncate tables:

TRUNCATE TABLE [Exceptions]

TRUNCATE TABLE [ExceptionEvents]

TRUNCATE TABLE [EventLog]

-- Recreate Foreign Key Constraints (using common naming):

ALTER TABLE [ExceptionEvents]

WITH CHECK ADD CONSTRAINT [FK_ExceptionEvents_EventLog]

FOREIGN KEY([LogEventID])

REFERENCES [EventLog] ([LogEventID])

ON DELETE CASCADE;

ALTER TABLE [EventLog]

WITH CHECK ADD CONSTRAINT [FK_EventLog_Exceptions]

FOREIGN KEY([ExceptionHash])

REFERENCES [Exceptions] ([ExceptionHash])

ON DELETE NO ACTION;

DROP FUNCTION [sys_currentDNNVersion]
