In software engineering, software rejuvenation is an approach to help prevent performance degradation and other associated failures related to software aging. This proactive technique was identified as a cost-effective solution during research at the AT&T Bell Laboratories on fault-tolerant software in the 1990s.〔Cotroneo, D., Natella, R., Pietrantuono, R., and Russo, S. 2014. A survey of software aging and rejuvenation studies. ACM J. Emerg. Technol. Comput. Syst. 10, 1, Article 8 (January 2014), 34 pages.〕 There are simple techniques and complex techniques to achieve rejuvenation. The method most individuals are familiar with is the hardware or software reboot. A more technical example would be the web server software Apache's rejuvenation method. Apache implements one form of rejuvenation by killing and recreating processes after serving a certain number of requests.〔Trivedi, K. S. and Vaidyanathan, K. 2007. Software Aging and Rejuvenation. Wiley Encyclopedia of Computer Science and Engineering.〕 Another technique is to restart virtual machines running in a cloud computing environment.〔Dario Bruneo, Salvatore Distefano, Francesco Longo, Antonio Puliafito, Marco Scarpa: Workload-Based Software Rejuvenation in Cloud Systems. IEEE Trans. Computers 62(6): 1072-1085 (2013)().〕 The IEEE International Symposium on Software Reliability Engineering (ISSRE) hosted the 5th annual International Workshop on Software Aging and Rejuvenation ((woSAR )) in 2013. Topics included: * Design, implementation, and evaluation of rejuvenation mechanisms * Modeling, analysis, and implementation of rejuvenation scheduling * Software rejuvenation benchmarking == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Software rejuvenation」の詳細全文を読む スポンサード リンク
