摘要：Computing environments have been increasingly complex, making managing them difficult. Self-Adaptive methods are used because these do not reveal internal structure and adapt to the environment. Our previous study uses an activation switch that determines components’ tasks. However, they may not work due to the external influences such as viruses because test cases do not contain all cases. If many processes are executing, the shut-down component can waste system resources. In this paper, we propose detecting errors that occur in the Self-Adaptive module and reuse the resources that the shut-down component locks. This can reduce the number of active component when many processes have executed and make the system safer. The paper applies the proposed approach to a video conferencing system to evaluate it. This compares the adaptation of the several approaches with this approach. When many file transfer tasks are active, the number of components is compared. In these experiments, we found abnormal states from the previous study and reduced resource usage through resource reuse
