“…Published results are based on either analytic models or simulations (Dohi et al 2000). Early results of a measurement experiment at Tokyo Institute of Technology are very encouraging, where rejuvenation increased the MTTF by a factor of two (Kourai 2008, personal communication, January 9) on the system reported in (Kourai and Chiba 2007).…”

Companies are expected to keep their systems up and running and make data continuously available. Several recent studies have established that most system outages are due to software faults. In this paper, we discuss availability aspects of large software-based systems. We begin by classifying software faults into Bohrbugs and Mandelbugs, and identify aging-related bugs as a subtype of the latter. We then examine mitigation methods for Mandelbugs in general and aging-related bugs in particular. Finally, we discuss techniques for the quantitative availability assurance for such systems.

Demands on software reliability and availability have increased tremendously due to the nature of present day applications. We focus on the aspect of software for the high availability of application servers since the unavailability of servers more often originates from software faults rather than hardware faults. The software rejuvenation technique has been widely used to avoid the occurrence of unplanned failures, mainly due to the phenomena of software aging or caused by transient failures. In this paper, first we present a new way of using the virtual machine based software rejuvenation named VMSR to offer high availability for application server systems. Second we model a single physical server which is used to host multiple virtual machines (VMs) with the VMSR framework using stochastic modeling and evaluate it through both numerical analysis and SHARPE (Symbolic Hierarchical Automated Reliability and Performance Evaluator) tool simulation. This VMSR model is very general and can capture application server characteristics, failure behavior, and performability measures. Our results demonstrate that VMSR approach is a practical way to ensure uninterrupted availability and to optimize performance for aging applications.

“…Microreboot has been applied to recovery from failures of the Linux kernel [6] and the Xen VMM [14]. Microreboot has also been used for proactive rejuvenating of the Xen VMM and PrivVM [11]. None of the prior works presented the general challenges to implementing microreboot for low-levels ystem software, based on experience with multiple components and multiple mechanisms.…”

Abstract-Av ailability is increased with recovery based on component microreboot instead of whole system reboot. There areunique challenges that must be overcome in order to apply microreboot to low-levels ystem software. These challenges arise from the need to interact with immutable hardware components on one hand and, on the other hand, with a wide variety of higher levelw orkloads whose characteristics may be unknown. As an example, we describe our experience with applying microreboot to system-levelv irtualization software. Specifically,i mplementing microreboot for all the components of the widely-used Xen virtualization infrastructure. We identify the unique difficulties with applying microreboot for such low-levels oftwarea nd present our solutions. We present measures of the complexity of different classes of solutions and experimental results, based on extensive fault injection, showing the effectiveness of the solutions.
