Instrument drivers also provide a common framework, so that a test engineer can move quickly, and productively, between instruments without having to learn everything from scratch. Instrument drivers provide a higher-level interface that helps to provide a more abstract view of the instrument that is easier to understand.On Linux and UNIX, to display a list of installed drivers, type odbcinst -q -d. The ODBC driver that the Driver attribute points to is not installed on your machine. The ODBC Driver Manager relies on the Driver attribute to know which ODBC driver to load. The Driver attribute is either missing from the data source or has an invalid value.
