Issue 751:  Inclusion of standard exception (orb_revision)
Source:  (, )
Nature:  Uncategorized Issue
Severity:  Significant
Summary: Summary:   The proposal is to define a new standard exception, called
   EXTERNAL_ACCESS (the name is not important) that carries
   an any value.  Another alternative may be to re-define
   the exception COMM_FAILURE so that it may carry an any in
   addition to the existing minor and completed fields.

Discussion: 
Not clear that an RTF is the right place for  adding such featurelets. This should be added as part of some appropriate submission to some RFP.

Title:

  Inclusion of a standard exception that operations on attributes
  may raise to carry additional info.
  
Description:

  One of the most important benefits of using CORBA is its value
  as a technology to integrate heterogeneous systems that are
  not necessarely based on CORBA.  In that context, CORBA can
  be used to encapsulate access to non-CORBA systems and bridge
  can be developed that enable to present a CORBA 'view' of a
  existing non-CORBA system.
  
  Developing such bridges typically involve mapping the interface
  a non-CORBA system provides into OMG IDL.  Some operations that
  are visible through the interface of an external system may be 
  better mapped as attributes associated to an interface defined
  in OMG IDL.  Bridges would convert requests associated to
  attributes into requests of a specific protocol that gives 
  access to the external system (a remote Database, a CMIP
  or SNMP agent, etc).  There may be protocol errors that are detected
  in the bridge that would be properly mapped as exceptions.  In
  the case of attributes, the only alternative is to raise a
  standard exception.  However, those standard exception cannot
  carry any specific info that helps.
  
  The proposal is to define a new standard exception, called
  EXTERNAL_ACCESS (the name is not important) that carries
  an any value.  Another alternative may be to re-define
  the exception COMM_FAILURE so that it may carry an any in
  addition to the existing minor and completed fields.
