Usually, code generation is employed to create a system's software components. Although this approach yields software with a good runtime performance, the resulting system behaviour is static. Changes to the behaviour model necessarily provoke an iteration in the code generation workflow and a re-deployment of the generated artefacts. In the area of autonomic systems engineering, it is assumed that systems are able to adapt their runtime behaviour in response to a changing context. Thus, the constraints imposed by a code generation approach make runtime adaptation difficult, if not impossible. This article investigates a solution to this problem by employing interpretation techniques for the runtime execution of UML State Machines, enabling the adaptability of a system's runtime behaviour on the level of single model elements. This is done by devising concepts for behaviour model interpretation, which are then used in a proof-of-concept implementation to demonstrate the feasibility of the approach. For a quantitative evaluation we provide a performance comparison between the proof-of-concept implementation and generated code for a number of benchmark models. We find that UML State Machine interpretation has a performance overhead when compared with static code generation, but found it to be adequate for the majority of situations, except when dealing with high-throughput or delay-sensitive data.","PeriodicalId":168314,"journal":{"name":"International Symposium on Software Engineering for Adaptive and Self-Managing Systems","volume":"270 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124375370","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}

During the development of a traffic monitoring system with support for self-healing, we have noticed that simple MAPE loops are not sufficient to deal with the more complex failure scenarios. To manage the adaptations in these scenarios, we extend MAPE loops with support for two types of coordination. First, we introduce support for intra-loop coordination enabling MAPE computations within one loop to coordinate with one another. Intra-loop coordination allows the execution of multiple sub-loops within one control loop. Second, we introduce support for inter-loop coordination enabling MAPE computations across multiple loops to coordinate with one another. Inter-loop coordination allows the MAPE computations of different loops to coordinate the various phases of adaptations. We show how we used the extensions to support self-healing in the traffic monitoring system. We discuss an implementation framework that supports coordination of MAPE loops, and from our experiences offer recommendations for future research in this area.","PeriodicalId":168314,"journal":{"name":"International Symposium on Software Engineering for Adaptive and Self-Managing Systems","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121466324","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}

As those applications are composed of individual services, they have to react to failures of those services to ensure that the applications maintain their expected functionality and quality. Self-adaptation is one solution to this problem, as it allows applications to autonomously react to failures. Currently, monitoring is typically used to identify failures, thus triggering adaptation. However, monitoring only observes failures after they have occurred, which means that adaptation based on monitoring is reactive. This can lead to shortcomings like user dissatisfaction, increased execution times, and late response to critical events. Pro-active adaptation addresses those shortcomings, because in such a setting, the application detects the need for adaptation and thus can adapt before a failure will occur. However, it is important to avoid unnecessary pro-active adaptations, as they can lead to severe shortcomings, such as increased costs or follow-up failures. This means that when taking pro-active adaptation decisions it is key that there is confidence in the predicted future failures, i.e., pro-active adaptation should only be performed if there is certainty that the failure could in fact occur. To avoid unnecessary adaptations, we introduce an approach based on augmenting service monitoring with online testing to produce failure predictions with confidence. We demonstrate the applicability of our approach using a scenario from the eGovernment domain.","PeriodicalId":168314,"journal":{"name":"International Symposium on Software Engineering for Adaptive and Self-Managing Systems","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115656371","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}

In this context, web service composition has a considerable impact on the delivered service affecting its quality (QoS). There is therefore a need to keep the service QoS parameters under control when the service is delivered by a combination of different web services. This paper investigates the composition of web services, and its implications on the overall QoS guarantees as represented by the service response times, when autonomic computing control mechanisms are in place. A control based approach of the autonomic computing concept is used to investigate the dynamic composition of web services when the service is provided by a set of web services linked via cooperation protocols that define a global process choreography. Web services are modeled as scheduled computational processes waiting in a queue to cooperate in delivering the service. The paper proposes an input-state-output mathematical model for web services and further investigates, in this context, their composition hypothesis, principles, and rules.","PeriodicalId":168314,"journal":{"name":"International Symposium on Software Engineering for Adaptive and Self-Managing Systems","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127315913","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}
