This phenomenon usually results from the accumulation of error conditions, such as memory leaks, round-off errors, file tables not released, etc. Unexpected downtime cost due to software aging is huge, particularly for e-commerce Websites and safety/business-critical applications. Software rejuvenation is an effective but expensive fault tolerance technique to deal with software aging phenomenon. This technique usually involves the termination of services due to the restart of computer systems. In this paper, a ¿lightweight¿ complementary technique of software rejuvenation is proposed to reduce the severity of software aging in terms of its impact on system resource usage by online tuning the settings of related parameters. Unlike traditional software restart involved in traditional rejuvenation, this technique is based on the idea of fine adjustment of software state. Experiments are conducted to reveal the relationship between certain parameters of Web server and resource usage. Accordingly, a PI (proportional-integral) controller is designed to online tune the parameters of web server with the purpose of counteracting the effect of software aging. Simulation results show that the technique is cost-effective.","PeriodicalId":436527,"journal":{"name":"2008 IEEE International Conference on Software Reliability Engineering Workshops (ISSRE Wksp)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134486037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When an application is serving live in production, fixing such issues is close to impossible. Software rejuvenation techniques can be used effectively to avoid failure, but will incur some downtime if a single instance of the application is running. With two instances the system can be engineered in such a way that there is at least one instance running at any time. There may be further reduction in operating expenses if an intelligent program can take charge of executing rejuvenation tasks as required. This paper describes the implementation of such closed loop software rejuvenation in a real world application and the resulting improvement in availability thereof.","PeriodicalId":436527,"journal":{"name":"2008 IEEE International Conference on Software Reliability Engineering Workshops (ISSRE Wksp)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115431861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper discusses foundational aspects of the software aging phenomenon, introducing new concepts and interconnecting them with the current body of knowledge, in order to compose a base taxonomy for the software aging research.

This paper presents the issues of performability management in a virtualized data center that hosts multiple services using virtualization. One of main cause of performability degradation is software aging in both virtual machines (VMs) and virtual machine monitor (VMM) in virtualized data center (VDC). Software rejuvenation is a cost effective and a proactive method to counteract software aging. During software rejuvenation operations, there occurs down time, therefore, VM placement and the rejuvenation schedules for VMs and VMM need to be optimized so as to maximize the performability in a VDC. We introduce the state of the art technology on software aging and rejuvenation in virtualized data center and we formulate this problem and show our approach.","PeriodicalId":436527,"journal":{"name":"2008 IEEE International Conference on Software Reliability Engineering Workshops (ISSRE Wksp)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133788324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a unified model to describe the behavior of long running software systems with performance degrading factors such as system aging and various recovery techniques such as rejuvenation, checkpointing, rollback recovery, restart and replication. The proposed unified model is described as a fluid stochastic Petri net (FSPN). The FSPN formalism offers a descriptive language that allows a compact and precise description of the model behavior. Various analysis methods can be applied to obtain numerical results for the performance indices of interest.
