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

pro oholder -RO -db oradb -ld orademo -H host1 
  -S oserviceA -U scott -P tiger
