Windows 2008 server and datafiles

Hello Jock,

Very easy if you take the path of least resistance.

Install the ODB software, choosing the right version for the clients.
By default, the ODB will run with a test set of data in the ODB folder, so I renamed my DF1 to match and put it in the same location until I got brave.
I kept the default TCP port, 5913
I do allow any sharing of the datafile with traditional methods as this will mess with the integrity of the DF.
I connect to the datafile using the 4GL command as usual with this syntax:

Open data file {odb://}

If you want to query the open datafiles that are being served by the ODB, use this command:
Prompt for data file {odb://}
You will get a prompted window with the open DF files.

One wee point, if you have multiple segments, then each segment must be added to the XML setup file.

Quite easy and used mainly on a Mac workstation, server OS not required, be brave.
