The jtds driver covers both servers because it does a lot of conditional processing based on both the jdbc connection string and packets returned from the server. > Couldn't get Sybase to work with Ubuntu 10 (worked fine on 9), but 10.10's > anyway a desaster. > Looking forward to v11, coming April 28/29.

It works, but it is horribly slow. It is slightly faster than their OLEDB driver in some cases and slower in others. But I don't think it will ever work on linux because the Sybase ADO.NET driver is actually just a managed wrapper around their unmanaged windows driver. I'll keep you informed if I'm able to make any more progress with updating the mono driver to work with 12.5 and greater. Cheers, Troy
