Re: real time importing to Oracle.

To add to Mark's suggestion, you may also consider an external program kicked off by a cron job that periodically looks at the file, then posts updates to the database. I've been poking into Perl on my current project and it seems to handle things like that pretty nicely - but there's certainly many other ways to get this job done.
