UDC Oracle ODBC Connection Issue

[Rehan]

I am using Qlik Sense Sever 13.51.4. I am trying to connect to the Oracle Database tables for UDC using the below string 

Driver={Oracle in OraClient 12Home3};dbq=Databasename;uid=NUser_Name;pwd=Password;

I am getting the error as attached. 

I am able to created a ODBC connection on the sever successfully but not in UDC. what am I missing here 

I have the User table name defined as Owner.User_Table

Attribute table as Owner.Attribute_Table

I solved all my problems wuth UDC using "windows" ODBC connection not Qlik.

In UDC, I use the same string as in "data connection", insert the DSN name as in the following image
