چکیده

In this paper, we describe a new approach to enhance the performance of CORBA-based applications. For that purpose, we improve access to CORBA objects with the help of value types. In this way, only few changes are necessary to speed up existing CORBA applications. Moreover, we discuss several techniques for updating cache objects within the scope of the CORBA event service. Finally, we compare the performance of these techniques.

A Generic Filtering Technique Using Value Types in CORBA-based Applications

The performance of a distributed application strongly depends on the frequency of its distributed calls. In this paper we present a generic approach to improve the performance of CORBA-based applications by filtering the access to CORBA objects. We use value type objects to implement the filtering rules. As an example, we show how generic filtering can be used in the context of the publisher/su...

Using Reflexivity to Interface with CORBA

Most bindings to CORBA are based on the construction of stubs, which translate a language call into a CORBA invocation. This paper shows an alternative way to build a binding, using the reflexive facilities of an interpreted language. Like other CORBA bindings, this binding allows a program to manipulate CORBA objects in the same way it manipulates local objects. Unlike conventional bindings, h...

Object Interconnections C + + Servant Managers for the Portable Object Adapter ( Column 14 )

Welcome to the final installment of our series covering the new CORBA Portable Object Adapter (POA) specification. The POA allows servers to (1) generate and interpret object references, (2) activate and deactivate servants, (3) demultiplex requests to map object references onto their corresponding servants, and (4) collaborate with the automaticallygenerated IDL skeletons to invoke operations ...
