As standards-based quality of service QoS enabled component middleware automates integration and configuration activities it is increasingly being used as a platform for developing open DRE systems that execute in environments where operational conditions input workload and resource availability cannot be characterized accurately a priori. Although QoS-enabled component middleware offers many desirable features however it historically lacked the ability to allocate resources efficiently and enable the system to adapt to fluctuations in input workload resource availability and operating conditions. This paper presents three contributions to research on adaptive resource management for component-based open DRE systems. First we describe the structure and functionality of the resource allocation and control engine RACE which is an open-source adaptive resource .
