[Samba] Samba and Foxpro for Unix

Hi !

I have an unique situation.

An SCO Unixware 7.1.3 with Samba 2.2.7a (yes, i know; it sucks !)

On the machine, is running MS Foxpro 2.6 for UNIX (it's running pretty well
for  several years) but due to new demands (like Crystal Reports, Visual
view; etc) the directories with DBF files were shared using Samba. At the
beginning, when everything was only about reading, there were no problems.
But now, it's necessary to write to the DBF files from the Visual
Application (Visual Basic) and now there are some problems. While a user may
be reading data from the Visual application, and someone else writes to the
DBF file from the FoxPro for UNIX, the changes are not being seeing in the
Visual application. And if the user from Visual writes data to the DBF,
there's a data corruption then; because of the concurrent connections from
the FoxPro from Unix.

I think it's a matter of oplock issue between Fox and Samba. Samba opens the
DBF file, without concerns if FoxPro has the file open, and viceversa. When
everyone is running only the Visual application, there's no problem. If the
users are running only FoxPro for Unix, there's no problems. If the users
run FoxPro for Unix for read/write and Visual for read only, there's no

The problems araise when the users are running FoxPro and Visual for read
and write files simultaneosly.

Any idea to run this configuration smoothly?

Thanks in advance for the help.

Kind regards.
