How to Configure Oracle EBS with a Separate Database Server?

have installed Oracle E-Business Suite (EBS) on Server A, but I want the database to be on a separate machine, Server B.

What are the necessary configurations to make this work? Is it enough to configure tnsnames.ora on Server A and listener.ora on Server B? Or are there additional steps required?

I would appreciate any guidance on this setup. Thanks!

So far, I have configured tnsnames.ora on Server A (Oracle EBS) and listener.ora on Server B (Database). Additional Information:

The database listener on Server B is running. I can successfully tnsping the database from Server A. However, Oracle EBS is still unable to connect to the database.

Your ENTRA users will get authenticated via JSON Web Tokens, and their Entra roles will determine which ORDS REST APIs they can hit.

When they hit an endpoint, it'll execute code in the database as the database user that owns the schema where the REST API is defined, not as Entra defiend end user. In fact, the Entra users won't have accounts in the database (they could, but wont' need to).

The :current_user field as far as ords is concerned would be the corresponding oauth2 client or JWT issued for the authorizied session.

Your prehook should be able to alter the session to set the context that would put your RLS/VPD security policy in play.
