A developer can specify, at design time, an abstract service. At run time a concrete implementation of the abstract service is dynamically selected. In this scenario service selection is usually performed assuming that all the implementations of an abstract service have the same interface or protocol. This assumption is not necessarily true in an open world setting, where services built by different organizations are made available. In this paper we address the problem of invoking services having an interface or protocol different from those originally expected by the service requester. We have identified a number of possible mismatches between services and some basic mapping functions that can be used to solve simple mismatches. Such mapping functions can be combined in a script to solve complex mismatches. Scripts can be executed by a mediator that receives an operation request, parses it, and eventually performs the needed adaptations. The definition of the scripts can be partially automated.","PeriodicalId":168314,"journal":{"name":"International Symposium on Software Engineering for Adaptive and Self-Managing Systems","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121546397","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}

It works by identifying tuning parameters and rearchitecting to expose them as a separate control panel module. The project poses three distinct research challenges: automating the identification of tuning parameters, rearchitecting to centralize and expose them, and combining these two capabilities to facilitate the integration of existing software into autonomic frameworks. Our previous work focused on the second problem, automating the rearchitecture to expose and isolate tuning parameters. In this paper we concentrate on the first problem, automating the identification of tuning parameters. We begin with an empirical study of documented tuning parameters in a number of open source applications. From our observations of these known tuning parameters, we create a catalogue of different kinds and organize them into a taxonomy. Finally, we characterize a member of the taxonomy as a source code pattern that is used to find similar tuning parameters. We report our experience in applying this methodology in the context of a large, open source Java system.","PeriodicalId":168314,"journal":{"name":"International Symposium on Software Engineering for Adaptive and Self-Managing Systems","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129832915","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}

Many research projects investigate mechanisms to adapt software systems effectively in order to ease evolution. By observing its internal state and surrounding context continuously using feedback loops, an adaptive system is able to analyze its effectiveness by evaluating quality criteria and then self-tune to improve its operations. The goals of these feedback loops range from keeping single variables in a prescribed range to satisfying non-functional requirements by regulating decentralized, interdependent subsystems.\u0000 To be able to observe and possibly orchestrate continuous evolution of software systems in a complex and changing environment, we need to push monitoring of evolving systems to unprecedented levels. It has been established that security has to be built into a system from the ground up and cannot be added as an afterthought - the same is probably true for intensive monitoring. We propose to monitor adaptive systems with autonomic elements to enhance their assessment capabilities. In this paper, we discuss how to build monitoring into Java programs from the ground up with reflection technology to detect normal and exceptional system behavior.","PeriodicalId":168314,"journal":{"name":"International Symposium on Software Engineering for Adaptive and Self-Managing Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128017919","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}

We observe that software systems of significant complexity, especially those made of components, are often redundant, in the sense that the same functionality and the same state-transition can be obtained through multiple sequences of operations. This redundancy is the basis to construct effective workarounds for component failures. In particular, we assume that failures can be detected and intercepted together with a trace of the operations that lead to the failure. Given the failing sequence, the system autonomically executes one or more alternative sequences that are known to have an equivalent behavior. We argue that such workarounds can be derived with reasonable effort from many forms of specifications, that they can be effectively prioritized either statically or dynamically, and that they can be deployed at run time in a completely automated way, and therefore that they amount to a valid self-healing mechanism. We develop this notion of self-healing by detailing a method to represent, derive, and deploy workarounds. We validate our method in two case studies.","PeriodicalId":168314,"journal":{"name":"International Symposium on Software Engineering for Adaptive and Self-Managing Systems","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124369618","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}

These systems are expected to enhance their functionality and improve their performance by building communities of autonomous agents which exploit local and global networking. Such mechatronic systems will therefore include complex coordination protocols which require execution in real-time and reconfiguration of the locally employed control algorithms at runtime to adjust their behavior to the changing system goals leading to self-adaptation. In this paper we will present an extension of the MECHATRONIC UML approach which will enable us to model collaborations between components which include structural adaptation and multi-ports. Besides the modeling of complex collaborations and the rules to join and leave these collaborations via ports and multi-ports, we propose to employ hierarchical state machines with a dynamic number of submachines to model the behavior of the multi-ports. For the collaborations this involves the related protocols, while for the components we have to refine this behavior to ensure a proper synchronization with other parts of the component behavior.","PeriodicalId":168314,"journal":{"name":"International Symposium on Software Engineering for Adaptive and Self-Managing Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126848860","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}

Therefore, understanding the requirements of an adaptive system is crucial to developing them correctly. Developers need to be able to reason about the requirements of a system's adaptive behavior. Adaptation semantics are intended to describe how systems behave during adaptation. Previously, Zhang and Cheng formally specified three commonly occurring adaptation semantics in terms of Adapt operator-extended LTL (A-LTL). This paper presents goal-oriented specifications of these three adaptation semantics. These specifications, specified with the KAOS methodology, provide a graphical wrapper to the formal A-LTL specifications of the semantics. The combination of the goal-oriented, graphical KAOS specifications and A-LTL specifications provides the benefits of formal specifications as well as the benefits of an easier to understand, graphical, and more intuitive presentation of adaptive systems requirements. This work also provides a means to incorporate the adaptation semantics into the goal-oriented requirements specifications of an adaptive system.","PeriodicalId":168314,"journal":{"name":"International Symposium on Software Engineering for Adaptive and Self-Managing Systems","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121919477","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}
