I am not sure what it is that you are looking for. Do you wish to use Fileshare on a separate server machine or on the local machine so that you could implement transaction logging?
To use Fileshare remotely you would need to install and license the Server for COBOL product on the server where you wish Fileshare to be running. Your files should also be located on that server.
The configuration for Fileshare would depend on how you wish to access the files from your application and whether or not you wish to have some files accessed thru Fileshare and some files accessed locally.
Please read through the Fileshare documentation and if you have any specific questions then please post them here.
Thanks.
