Gopinath,

UO.NET is a proprietary interface for client software applications to access U2 database resources using an API. It is neither an ODBC client or an ODBC server but uses specific U2-based DLLs such as UODOTNET.DLL. There are a number of examples of usage freely available on the Web by searching. There are also examples shipped with the client libraries and these can usually be found under C:U2UniDKuonetSamples

So to answer your question directly, neither SQL Server nor ODBC are involved. Regarding Infolease, I am not aware of what this is so cannot comment directly. If however it is an application suite based upon one of the U2 database products (whether UniData or UniVerse)  then the application provider should be able to assist, If they in turn require assistance then they will have a formal route for technical assistance through their local Rocket U2 suppler, whether OEM, Distributor or directly from Rocket.

Hoping this helps.

Regards

JJ

There is another new U2 Toolkit driver with native mode. It will include all IBMU2.UODONET function with more other features. The latest driver will support .NET 6 and EF Core 6.
