Auto-Deleting Audit Trace (.trc) Files

We have a Windows 2008 R2 server running MS SQL 2008. The .trc  files are putting a lot of stress on the disk space of our server and are being produced about every minute at 5 MBs a file. What are they for? Is there a way to limit the amount of files through SQL safely?

Seems SQL profiler trace is creating the 5MB files using SQL server Profiler tool or usign SQL agent job.

Can you run this query on the sever

select * from sys.sysprocesses where program_name like '%profiler%' or lastwaittype = 'TRACEWRITE'

You can limit the trace file size by putting the value in "set maximum file size" value text box.

Yes you can set retention policy but there is no any inbuild feature to auto remove the old files. You have to setup a SQL agent job which will perform this task for you.

You can delete the old files using  XP_cmdshell system stored procedures. Just schedule a sql job and copy the below code. Please change the parameters accordingly.

exec xp_cmdshell 'forfiles /P <D:\tracef\> /M *.trc /D -1 /C "cmd /c del @file" '

/P <File directory location>  , /D < number of old days > /M <search the extention> , /C < delete command>

Please find the Best solution for this issue is use the powershell script in T-SQL Job then schedule.

Get-ChildItem -Path "C:\SQLServer\Data" -include *.trc -recurse | Where {$_.LastWriteTime -lt  (Get-Date).AddDays(-14)} | Remove-Item -Force
