%X As a software application runs, it's performance and efficiency degrades over time due to factors such as memory fragmentation, counter inflation, and software errors. This is referred to as "Software Aging". "Software Rejuvenation" is a set of techniques to rectify this problem and return the software to its highest performance state. There are two methods to achieve this:1)a complete restart of the affected software system 2)"Micro-reboot" which restarts only affected components of a software system. When using "Micro-Reboot", a component undergoing restart may not be temporary available during the restart process. Therefore a "Request-Retry" protocol is required, to insure the continued operation of the application during this process. This new software rejuvenation framework is based on the J2EE component model.
