Well, this is not how check_dbi would connect to an Oracle database.
Rather, you will need an 'oracle' driver for libdbi. According to the
website somebody is working on such a thing but it seems to be
incomplete and I don't know anything about the current status or whether
it's usable at all, I'm afraid.

This is exactly what check_dbi is meant for. Please note though, that
you can (currently) only check a single value only. The plugin uses the
first (CURRENT_UTILIZATION) and simply ignores all other values.

Could you please provide more information about that error, like the
full compiler output? common.h is shipped with nagios-plugins, so I
suppose there is some other error.
