Patent number: 10810182Abstract: Data entities in a client-server system are accessed. The client-server system comprises a set of clients, a server system, and a repository for storing a plurality of data entities. The server system comprises an inter-transactional cache, the inter-transactional cache being accessible for each client of the set of clients. A first client of the set of clients comprises a first intra-transactional cache. If a copy of a first data entity is in the inter-transactional cache, a version identifier of the original first data entity is read from the repository. If the copy of the first data entity is to be accessed with an exclusive lock, a copy of the copy of the first data entity is added to the first intra-transactional cache. The copy of the copy of the first data entity in the first intra-transactional cache is accessed for further processing of the first data entity by the first client.Type: GrantFiled: December 13, 2017Date of Patent: October 20, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Frank Neumann, Gerhard Pfau

Patent number: 7774354Abstract: Method and system for providing results for task list queries to Workflow Management Systems (WfMSs) and Human Task Management Systems (HTMSs). In one aspect, a method for providing the result of a task list query to a human task database includes caching data from the database in a plurality of materialized views. A new request for a list of tasks from the database is received, and a new query is created when the new request applies to the data in a particular materialized view. When the particular materialized view includes data that requires updating from more recent data in the database, the materialized view is so updated. The new query is executed against the data in the materialized view instead of executing the new query against the data in the database.Type: GrantFiled: August 2, 2007Date of Patent: August 10, 2010Assignee: International Business Machines CorporationInventors: Jonas Grundler, Frank Neumann, Gerhard Pfau

Patent number: 7386577Abstract: Transactions within a process model are determined by grouping a set of individual process activities into a single transaction. This effectively reduces the processing overhead, and, therefore, improves the overall throughput and latency of the execution of the process model. The transaction is determined by performing an optimization procedure that takes into account the structure of the process model as well as various properties of the single process activities of the process model. Analysis of the properties of the process activities as well as application of the optimization procedure is performed dynamically during execution of the process model by a workflow engine.Type: GrantFiled: February 2, 2005Date of Patent: June 10, 2008Assignee: International Business Machines CorporationInventors: Andreas Arning, Matthias Kloppmann, Frank Leymann, Gerhard Pfau, Dieter Roller, Andreas Schmitz, Friedemann Schwenkreis, Claudia Zentner

Publication number: 20070162339Abstract: In a computer system of a sender, means is generated for a message. The means represents a reward offer for a receiver of the message for acting on the message. The message and means are sent to at least one receiver. The message and means associated with the message are received in a receiver computer system. It is checked whether the message is acted on in accordance with the reward offer in the receiver computer system. Realization of the reward offer is initiated in response to the message being acted on in accordance with the reward offer.Type: ApplicationFiled: January 9, 2007Publication date: July 12, 2007Inventors: Andreas Arning, Matthias Kloppmann, Gerhard Pfau, Dieter Roller

Publication number: 20050209841Abstract: The present invention provides a method, a data processing system as well as a computer program product for optimizing process properties for workflows with failing activities. The invention makes use of monitoring occurrence of failure of each activity of a process model of a workflow and further monitoring properties that are associated to compensating activities that are required in order to repair the failure of an activity. The method makes explicit use of determining alternative execution sequences and selecting one of the plurality of alternative execution sequences of the process model, that optimizes the process property in case of failure of an activity of the process model. The process model itself remains unaffected and need not to be remodeled.Type: ApplicationFiled: March 10, 2005Publication date: September 22, 2005Inventors: Andreas Arning, Matthias Kloppmann, Frank Leymann, Gerhard Pfau, Dieter Roller, Andreas Schmitz, Friedemann Schwenkreis, Claudia Zentner

Patent number: 5800164Abstract: The present invention deals with a system for the selection of form and color structure of teeth, in particular for application in the preparation and production of ceramic or plastic-composition faced tooth replacements. The system consists of several assortments comprising models and image representations as well as layering diagrams of different tooth forms and tooth color structures. A comparison of form and color between the patient's teeth and the models is then made, whereby the suitable assortment(s) are selected and can be reproduced true to nature in the dental laboratory, using the appertaining layering diagrams. The system according to the invention consists of several components which can be assembled to form a basic assortment.Type: GrantFiled: June 21, 1996Date of Patent: September 1, 1998Inventor: Gerhard Pfau
