Hello,
Thanks for the question about accessing an Oracle database from a VPS/dedicated server account. We don't have packaged solution on the issue, but it can be done per the posts I'm seeing (Connecting an Oracle server to Apache server. My suggestion would be to speak with a web developer or programmer. My apologies that we don't have a direct answer for you.
If you have any further questions, please let us know.
Kindest regards,
Arnel C.
