SCO UnixWare is not a strategic platform for RDBMS nor ODBC driver vendors.  Oracle's final release on this platform was 8.1.7, which is now unsupported.

IBM have never released DB2 on this platform.

Neither iWay nor DataDirect have ODBC drivers available for this platform, and there are no plans to produce them. These are the ODBC drivers Micro Focus use for testing.

Given the lack of support from major database vendors Micro Focus has no plans to add Micro Focus ODBC technology to this platform.  However, Server Express and Visual COBOL for Linux Intel provide OpenESQL support.
