Towards Resource Consumption Accounting and Control in Java: A Practical Experience

Abstract

Introduction All software components are not equivalent as far as resource access and consumption are concerned. Some components can do very well with sparse or even missing resources, while others require guaranteed access to the resources they need. In order to deal with non-functional requirements pertaining to resource utilisation we propose a contractual approach of resource management and access control. This idea is being investigated in the context of project RASC (Resource-Aware Software Components). In this project our objective is to provide software components with means to specify their requirements regarding hardware and/or software resources, and to design methods and models for utilising this kind of information at any stage of a component's life-cycle. This short paper reports the design of two software products called RAJE and JAMUS, whose development is in progress in the context of project RASC. RAJE is an extension of the standard Java 2 platform. It reifies s
