Split Access Database on eRoom needs to link to back end stored on eRoom

Hello Experts:
I have a split Access database stored in eRoom and want to move the backend portion of the application to eRoom, too.  Does anyone know if it's possible to re-link the database to tables sitting in eRoom?  When I tried to relink the application, I supplied the URL for the back-end in eRoom, it responded with "not a valid file name".  Not sure if this is even possible.  Anyone have any experience/success with this?

I assume that what you're trying to do is make the access database available to multiple users via a web site. I don't think this is going to work in regards to the back-end database. The issue is the protocols being used. When the database is on a local or mapped drive, your using the SMB protocol (I think that's right). This protocol allows for a constant connection to be open to a file and can create file locks (required for access databases).

Through a web connection, you're using a http protocol, which does not allot for constant connections to remain open and thus can't support file locks either. With http, the client sends a single request, and the server sends back data in response to the request. Something like GET HTTP 1.1 /  (send me the home page). One could use http to download a copy of the database, and run it on the local machine (works fine for the front-end portion of the database) but not to have a real-time connection open to the database (what you need for the back-end portion).

You might experiment with Replication. In other words, create a replicated copy of the database that can later be synchronized with a master. I don't know if that will help in your situation.

Thanks, you answered my question.  It's not possible.  Our current way of doing things is to have the app sit in eRoom, and the database sit on a network server (accessible to internal people).  That works fine. But, we have an external client who needs access to the database.  Without a VPN, we can't give the client access to our network server.  So, they're unable to connect.  I thought if we could move the backend to eRoom, too, we might have a solution.  Thanks for your explanation.
