SQL Server Tips: Path of the default trace file is null

In addition of my precedent blog about this subject “SQL Server Tips: Default trace enabled but no file is active…”, I add a new case where the default path of the trace file was empty.

The first step was to verify if the default trace is enabled with the command:

SELECT * FROM sys.configurations WHERE name=’default trace enable’

It is enabled, then I check the current running trace with the view sys.traces

SELECT * FROM sys.traces


As you can see, this time I have a trace but with a null in the Path for the trace file…

To correct this issue, the only way is to stop and reactive the trace in the configuration:

EXEC sp_configure 'show advanced options',1;
GO
RECONFIGURE WITH OVERRIDE;
GO
EXEC sp_configure 'default trace enabled',0;
GO
RECONFIGURE WITH OVERRIDE;
GO
EXEC sp_configure 'default trace enabled',1;
GO
RECONFIGURE WITH OVERRIDE;
GO
EXEC sp_configure 'show advanced options',0;
GO
RECONFIGURE WITH OVERRIDE;
GO

Et voila, I have a trace file now…
