It is similar in structure to the standard odbc.ini file. Users do not need to configure udbc.ini, unless they choose to use OpenLink's proprietary UDBC data access protocol. Users choose UDBC to bypass dependence on an ODBC driver manager. However, due to prevalence of iODBC and other driver managers on Unix, UDBC is no longer needed. OpenLink has dropped support for UDBC in its 5.0 releases." .
