Computer Associates International Inc says its use of The Object Management Group’s Corba IIOP protocol to plumb CA-Unicenter TNG systems management environment with distributed functionality does in no way stand at odds to its pact with Microsoft Corp. Corba already has a bridge to Microsoft’s COM, Common Object Model. IIOP, it observes, is fairly complimentary to The Open Group’s Distributed Computing Environment technology which it says Microsoft is getting more interested in. The way CA sees it, IIOP is basically TCP/IP with some Corba-defined message exchanges that serve as a common backbone protocol. Every object request broker (ORB) that calls itself Corba compliant must either implement IIOP natively or provide a half-bridge to it. Any proprietary ORB can connect with the universe of Corba ORBs by translating requests to and from the IIOP backbone. Nobody is going to ignore OLE/COM, now are they?
