My Mendix App was able to connect to Oracle DB for test.  After making some changes including entity updates,  I can not bring up the App online anymore.  However, the errors are encountered only if trying to connect to Oracle DB.  If using the Mendix build in DB, I can run the App for testing, no errors.  I am not sure if the problem is related to Oracle DB or something else?  I try multiple Oracle DB instances.  The error messages are different.  Please help to take a look.   Error messages from Oracle DB 1: new MxObject(): cannot create Mendix object. Check entity access for entity Administration.Account Error: new MxObject(): cannot create Mendix object.
