5.2.3.5 Why Use Oracle Tuxedo CORBA Extensions?

The Oracle Tuxedo software extends the interfaces defined in the CORBAservices specification, Chapter 6 “Life Cycle Service,” December 1997, published by the Object Management Group, for the following reasons:

• Although the CORBA-defined approach is powerful and allows various selection criteria, the interface used to query a FactoryFinder can be complicated to use.
• Additionally, if the selection criterion specified by the client application is not specific enough, it is possible that more than one reference to a factory object may be returned. If this occurs, it is not immediately obvious what a client application should do next.
• Finally, the CORBAservices specification did not specify a standardized mechanism through which an application server is to register a factory object.

Therefore, Oracle Tuxedo extends the interfaces defined in the CORBAservices specification to make using a FactoryFinder easier. The extensions are manifested as refined interfaces to the FactoryFinder that are derived from the interfaces specified in the CORBAservices specification.
