Distributed Object Computing

CORBA is the acronym for Common Object Request Broker™ Architecture, an architecture and set of specifications developed by the Object

Management Group™ (OMG™). The Object Request Broker enables objects to transparently make and receive requests and responses in a

distributed environment. It is the foundation for building applications from distributed objects. NonStop CORBA 2.6.1, which is based on OMG

CORBA 2.6.1 core specification and other OMG specifications, provides an infrastructure and development environment that enables system

administrators and software developers to process and develop distributed object applications and components. These applications and

components run on HP NonStop Kernel Open System Services (OSS). Language and object-adapter features enhance the portability of the

components you write using NonStop CORBA.

Client and server objects using NonStop CORBA 2.6.1 offer the software developer and systems administrator the following benefits:

Interoperation with other CORBA ORBs
