ApEx runs out of the database so I don't think you can do anything like that (I've never tried) but we do have an ApEx system that talks to multiple databases, you just use database links.

We would want to be able to access multiple databases. Can the Application Express Listener Product be configured to access mutliple databases? If not, what would be the recommended way to achieve this result? Jeffrey Beckstrom Database Administrator Greater Cleveland Regional Transit Authority 1240 W. 6th Street Cleveland, Ohio 44113
