CORBA3 — Object Adapter name problem in ORT

  • Key: CORBA3-125
  • Legacy Issue Number: 4440
  • Status: closed  
  • Source: Oracle ( Ken Cavanaugh)
  • Summary:

    The adopted specification for the Object Reference Template is
    ptc/01-04-03. This specification introduces adapter names for
    object adapters. Adapter names are needed in the definition of the
    ObjectReferenceTemplate abstract valuetype. An AdapterName is
    simply a sequence of strings that is used to identify an
    instance of an object adapter.

    In the case of the POA, the spec defines the AdapterName as follows
    in section

    In the case of the POA, the adapter name shall be the sequence
    of names starting with the root POA that is required to reach
    the POA using the find_POA call. The name of the root POA is
    the empty sequence.

    Also, in section

    The adapter_name attribute defines a name for the object adapter that
    services requestws for the invoked object. In the case of the POA,
    the adapter_name is the sequence of names from the root PAO to the POA
    that services the request. The root POA is not named in this sequence.

    The problem here is that the POA occupies the entire name space of
    possible adapter names, so an ORB that supports other proprietary
    object adapters cannot unambiguously identify instances of other
    object adapter through ServerRequestInfo.adapter_name.
