IIOP support in CICS

The Internet Inter-ORB protocol (IIOP) is a TCP/IP based implementation of the General Inter-ORB Protocol (GIOP) that defines formats and protocols for distributed applications. It is part of the Common Object Request Broker Architecture (CORBA). Both client and server systems require a CORBA Object Request Broker (ORB) to implement IIOP interoperability.

The Common Object Request Broker Architecture (CORBA) is a specification for a standard object-oriented architecture for distributed applications. It was defined by a consortium of over 500 information technology organizations called The Object Management Group (OMG). You can read the CORBA Architecture and Specification document at their web site:

CICS® provides an ORB and support for IIOP defined by CORBA 2.3.
