You may need to configure compatible communication channels.
Secures RMI JDBC communitation with a data source with a check for administrator authentication. For more information, see Using the WebLogic RMI Driver (Deprecated).
If the value of Compatibility is used, the server instance allows communication over an unsecure channel with the application's subject and no check for inbound administrator authentication when using RMI to access a data source. This setting reflects the legacy implementation behavior for RMI access to a data source and is a potential security vulnerability as it provides a client uncontrolled access to a database.
