The unixODBC driver manager uses the ODBCSYSINI environment variable to find and load
drivers.
The OCBC driver manager uses the configuration files that contain information about
target databases and driver location. All of the configuration files have an
.ini extension (for example, odbc.ini)
that can be identified by name and extension.
The environment variable identifier for the unixODBC driver manager points to the
directory containing the
odbc.ini and
odbcinst.ini files, for
example:
setenv ODBCSYSINI pathname
where
pathname points to the
odbc.ini file.
Configuration files that the ODBC driver manager uses have target database-specific
information:
-
odbc.ini contains the data source name (DSN)
information, which includes connection information, driver identifiers, and
other driver-specific attributes.
-
odbcinst.ini contains driver-specific information.
