摘要
"软件衰退"现象在软件系统中普遍存在,利用"软件抗衰"技术可以在软件出现衰退时提高系统性能,针对基于MIDAS三层架构系统结构的特殊性,提出一种双抗衰系统工作模型分布在中间层应用服务器和数据库服务器端协同工作,可以应对三层架构系统部分或整体出现衰退,采用应用级或系统级恢复,提高系统整体的性能,同时也保障了数据的完整性、安全性。
Software failures are common phenomenon in software system. Software rejuvenation technology is used to improve system performance when soft-ware aging happened. A kind of double soft-ware rejuvenation work model is introduced which distributes between interlayer application server and database server, Double soft-ware rejuvenation system aiming at the three-tier structure system of MIDAS- based uses application level or system level restoration to improve whole or part of system performance and secure user data.
