CORBA34 — Section: Part 2, Chapter 11 - MIOP

The MIOP does not provide an analogous operation to PortableServer::POA::create_POA() for the GOA (i.e. there is no PortableGroup::GOA::create_GOA). The lack of an operation of this nature prevents the ability for an interface (i.e. servant) to subscribe to multiple (i.e. more than one) multicast group. To specify to a POA to allow multiple entries in its Active Object Map, the POAs IdUniquenessPolicy would have to be set to MULTIPLE_ID. This can only be done via the POAs create_POA operation. Since there is no GOA create_GOA operation, a GOAs IdUniquenessPolicy cannot be set to MULTIPLE_ID, which prevents a servant from being able to be subscribed to more than one multicast group. I don't know if the OMG explicitly wants to prevent this capability, thus purposely leaving it out of the MIOP specification, or if this is simply an overlooked issue.
