## External Dependencies

On Linux operating system platforms, if you want to use any of the functionality that uses an ODBC connection, Micro Focus recommends explicitly setting the `ODBCSYSINI` environment variable. This variable specifies the directory that contains the `odbcinst.ini` file, which contains details of available ODBC drivers on your system.

For example, on some systems you must set `ODBCSYSINI=/etc`, and on others `ODBCSYSINI=/usr/local/etc`.

In particular, Micro Focus recommends that you set this environment variable if you want to use a SQL Fact Store with your Fact Bank systems, or Answer Bank statistics.
