Insbesondere wird der Einsatz von Transaktionen f{\"u}r verteilte Wikis betrachtet, die moderne Funktionalit{\"a}ten, wie Metadaten und zus{\"a}tzliche Indexe f{\"u}r die Navigation, unterst{\"u}tzen. Konsistenz und Dauerhaftigkeit der gespeicherten Daten erfordert die Behandlung von Knotenausf{\"a}llen. Die Arbeit schl{\"a}gt daf{\"u}r das Zellenmodell vor: Das Overlay wird aus replizierten Zustandsmaschinen gebildet, um Verf{\"u}gbarkeit zu gew{\"a}hrleisten. Das Transaktionsverfahren baut darauf auf und verwendet Two-Phase-Commit mit Fehlererkennung und Widerherstellung von ausgefallenen Transaktionsmanagern. Anwendungen wird eine Auswahl an pessimistischen und hybrid-optimistischen Nebenl{\"a}ufigkeitskontrollverfahren geboten, die die Minimierung von Latenzeffekten und die schnelle Ausf{\"u}hrung von Nur-Lese-Transaktionen erm{\"o}glichen. F{\"u}r die Beispielanwendung Wiki wird der erforderliche Pseudocode angegeben und die verschiedenen Nebenl{\"a}ufigkeitskontrollverfahren hinsichtlich ihrer Nachrichtenkomplexit{\"a}t verglichen.}, language = {de} } @incollection{PlantikowJorra2011, author = {Plantikow, Stefan and Jorra, Maik}, title = {Latency-Optimal Walks in Replicated and Partitioned Graphs}, series = {Database Systems for Adanced Applications}, volume = {6637}, booktitle = {Database Systems for Adanced Applications}, editor = {Xu, Jianliang and Yu, Ge and Zhou, Shuigeng and Unland, Rainer}, publisher = {Springer Berlin / Heidelberg}, doi = {10.1007/978-3-642-20244-5_3}, pages = {14 -- 27}, year = {2011}, language = {en} } @inproceedings{HoegqvistPlantikow2009, author = {H{\"o}gqvist, Mikael and Plantikow, Stefan}, title = {Towards Explicit Data Placement in Scalable Key/Value Stores}, series = {Architectures and Languages for Self-Managing Distributed Systems (SelfMan@SASO)}, booktitle = {Architectures and Languages for Self-Managing Distributed Systems (SelfMan@SASO)}, year = {2009}, language = {en} } @inproceedings{SchuettMoserPlantikowetal.2008, author = {Sch{\"u}tt, Thorsten and Moser, Monika and Plantikow, Stefan and Schintke, Florian and Reinefeld, Alexander}, title = {A Transactional Scalable Distributed Data Store}, series = {1st IEEE International Scalable Computing Challenge, co-located with CCGrid'08}, booktitle = {1st IEEE International Scalable Computing Challenge, co-located with CCGrid'08}, year = {2008}, language = {en} } @inproceedings{PlantikowHoegqvist2008, author = {Plantikow, Stefan and H{\"o}gqvist, Mikael}, title = {Continous Queries over Federated Social Networks}, series = {Fourth Doctoral Workshop on Mathematical and Engineering Methods in Computer Science (MEMICS 2008)}, booktitle = {Fourth Doctoral Workshop on Mathematical and Engineering Methods in Computer Science (MEMICS 2008)}, address = {Znojmo, Czech Republic}, year = {2008}, language = {en} } @article{PlantikowPeterHoegqvistetal.2009, author = {Plantikow, Stefan and Peter, Kathrin and H{\"o}gqvist, Mikael and Grimme, Christian and Papaspyrou, Alexander}, title = {Generalizing the Data Management of Three Community Grids}, series = {Future Generation Computer Systems (FGCS)}, volume = {25}, journal = {Future Generation Computer Systems (FGCS)}, number = {3}, doi = {10.1016/j.future.2008.05.001}, pages = {281 -- 289}, year = {2009}, language = {en} } @inproceedings{PlantikowReinefeldSchintke2008, author = {Plantikow, Stefan and Reinefeld, Alexander and Schintke, Florian}, title = {Transactions and Concurrency Control for Peer-to-Peer-Wikis: An Evaluation}, series = {Making Grids Work}, booktitle = {Making Grids Work}, editor = {Danelutto, Marco and Fragopoulou, Paraskevi and Getov, Vladimir}, doi = {10.1007/978-0-387-78448-9_27}, pages = {337 -- 349}, year = {2008}, language = {en} } @inproceedings{AndrzejakPlantikow2006, author = {Andrzejak, Artur and Plantikow, Stefan}, title = {Defining Fuzzy Logic Controllers with Scarce Model Data}, series = {First International Workshop on Feedback Control Implementation and Design in Computing Systems and Networks FeBID'06 (colocated with NOMS'06)}, booktitle = {First International Workshop on Feedback Control Implementation and Design in Computing Systems and Networks FeBID'06 (colocated with NOMS'06)}, address = {Vancouver, Canada}, year = {2006}, language = {en} } @inproceedings{PlantikowReinefeldSchintke2007, author = {Plantikow, Stefan and Reinefeld, Alexander and Schintke, Florian}, title = {Transactions for Distributed Wikis on Structured Overlays}, series = {DSOM}, volume = {4785}, booktitle = {DSOM}, editor = {Clemm, Alexander and Granville, Lisandro and Stadler, Rolf}, publisher = {Springer}, address = {Silicon Valley, CA, USA}, doi = {10.1007/978-3-540-75694-1_25}, pages = {256 -- 267}, year = {2007}, language = {en} } @inproceedings{AndrzejakGraupnerPlantikow2006, author = {Andrzejak, Artur and Graupner, Sven and Plantikow, Stefan}, title = {Predicting Resource Demand in Dynamic Utility Computing Environments}, series = {2006 International Conference on Autonomic and Autonomous Systems (ICAS 2006), 16-21 July 2006, Silicon Valley, California, USA}, booktitle = {2006 International Conference on Autonomic and Autonomous Systems (ICAS 2006), 16-21 July 2006, Silicon Valley, California, USA}, publisher = {IEEE Computer Society}, doi = {10.1109/ICAS.2006.44}, pages = {6}, year = {2006}, language = {en} }
