Oracle Schema

Is there a way…

I have one Oracle database.

I would like to divide Development, Test, Production up by SCHEMA within the same database.

Is there something in the database.yml that I can configure for this?

Well since schemas in Oracle are basically just users, you could have a different user for prod/test/dev.

I have not used Oracle but this link looks as if it might get you
going in the right direction
