In this example, the schema holder's physical name is oholder; it is read-only; the Oracle database's logical name is orademo; the host name is host1; the service name is oserviceA; the user ID is scott; the password is tiger. This configuration assumes you started the remote DataServer broker using this command line interface:

prowin32 oholder -RO -db oradb -ld orademo -H host1
