LOG files

Hi,
I have some LOG files, the extension of the file is LOG, and I don't know
where they came from. Some of them are named after my databases, and others
are not. One is almost 4 GB in size. GB is not a typo.
These files are locked, so I have to shut down to view them. Unfortunately,
they are not TXT files, so I can't view them anyway. I tried to rename the
files, but when I try and launch the application that uses SQL, I get an
error message.
Any help on this would be greatly appreciated.In SQL Enterprise manager , right click your database, go to properties,
then select the log tab, it will list the physical names of all of the tran
logs for that database..

are they listed as log files? I thought the transaction logs were the LDF
files?
Do you have any advice for truncating these logs and what settings are best
for them? How do I determine what information, and the date of the
information in these files?
Thanks so much !

ODBC).

Listed by who? Are then named .LOG? And are really database transaction log files? If so, ask the
person who created the database.

That is the recommendation, but you can name the files anyway you want.

If these are truly transaction log file, they are in binary format. You need 3:rd party app to read
the stuff, like Log Explorer from www.lumigent.com.
