1.1 Introduction to the Oracle Tuxedo CORBA Environment

The CORBA environment in the Oracle Tuxedo product is based on the CORBA standard as a programming model for developing enterprise applications with high performance, scalability, and reliability. Oracle Tuxedo CORBA extends the Object Request Broker (ORB) model with online transaction processing (OLTP) functions. The Oracle Tuxedo CORBA deployment infrastructure delivers secure, transactional, distributed applications in a managed environment.

CORBA objects built with the Oracle Tuxedo product are accessible from Web-based applications that communicate using the CORBA Object Management Group (OMG) Internet Inter-ORB Protocol (IIOP). IIOP is the standard protocol for communications running on the Internet or on an intranet within an enterprise.

Oracle Tuxedo CORBA has a native implementation of IIOP, ensuring high-performance, interoperable, distributed-object applications for the Internet, intranets, and enterprise computing environments. You can build integrated enterprise applications using multiple programming models. CORBA and Application-to- Transaction-Monitor-Interface (ATMI) applications can be developed with fully integrated transaction management, security, administration, and reliability capabilities.

The interoperability technology incorporated into Oracle Tuxedo CORBA provides for scalable connectivity between the CORBA and WebLogic Server environments. For information on interoperability see BEA Tuxedo Interoperability in the Oracle Tuxedo online documentation.
