Method, system, and computer program product for providing a four-tier corba architecture

A data processing system for providing a four-tier CORBA architecture, comprising:

• a three-tier CORBA network, said CORBA network including a first CORBA ORB coupled to a second CORBA ORB, said second CORBA ORB being coupled to a third CORBA ORB, wherein said first CORBA ORB occupies a first level of a network hierarchy, said second CORBA ORB occupies a second level of said network hierarchy, and said third CORBA ORB occupies a third level of said network hierarchy;
• and
• a global CORBA ORB coupled to said three-tier CORBA network, said global CORBA ORB occupies a top level of said network hierarchy over said first level, said global CORBA ORB functioning as a CORBA ORB and treating said first CORBA ORB as a managed node.

A computer program product in a data processing system for providing a four-tier CORBA architecture, said product comprising:

• instruction means for providing a three-tier CORBA network, said CORBA network including a first CORBA ORB coupled to a second CORBA ORB, said second CORBA ORB being coupled to a third CORBA ORB, wherein said first CORBA ORB occupies a first level of a network hierarchy, said second CORBA ORB occupies a second level of said network hierarchy, and said third CORBA ORB occupies a third level of said network hierarchy;
• and
• instruction means for coupling a global CORBA ORB to said three-tier CORBA network, said global CORBA ORB occupies a top level of said network hierarchy over said first level, said global CORBA ORB functioning as a CORBA ORB and treating said first CORBA ORB as a managed node.
