How do you do to empty this logfile and after shrink logfile
without disturb production environement
Thank you

BACKUP LOG WITH NO_LOG or TRUNCATE_ONLY and books online refers:
NO_LOG | TRUNCATE_ONLY
Removes the inactive part of the log without making a backup copy of it and truncates the log. This option frees space. Specifying a backup device is unnecessary because the log backup is not saved. NO_LOG and TRUNCATE_ONLY are synonyms. After backing up the log using either NO_LOG or TRUNCATE_ONLY, the changes recorded in the log are not recoverable. For recovery purposes, immediately execute BACKUP DATABASE. Satya SKJ

Yes, Shrink willnot release the free space to OS. Trucate log after you do Shrink operation, You will get your log in MB size . Happy trucation !!!! <img src=’/community/emoticons/emotion-1.gif’ alt=’

If you need a tailor-made output then you must use query to access sytem tables which is discouraged by MS in this case, so stick to the pre-supplied SPs. Satya SKJ
