摘要： The invention relates to a computerized method of managing workload within a Workflow-Management-System (WFMS) said WFMS comprising a process model, said process model comprising one or more activities being the nodes of an arbitrary graph, and directed edges of said graph defining a potential control flow within said process-model.The inventions suggests a determination step, wherein the process model is analyzed if a priority execution specification is assigned to said one activity comprising at least one Boolean predicate and a priority level.In a launching step said Boolean predicate is evaluated using a variable value not comprised in the process model but the variable value being comprised in a context of an instance of the process-model. If the Boolean predicate evaluates to TRUE, the launching step launches execution of said one activity in said activity's execution environment with an execution priority specified according to the priority level.

摘要： A technology for indicating and determining the availability of a multitude of application servers. The method comprises for each of application server a first step of inserting into an availability database a notification period defining an upper time limit for a repetition period of an availability signal, which is repeated as long as the application server is available. In a second step for each availability signal its corresponding time stamp is inserted as availability time into the availability database. The difference of the current time and a recent availability time compared to said notification period is representing a measure of availability for the application servers.

摘要： A method for optimizing request shipping within a plurality of distributed networked computer systems holding a distributed application the usage of which realizes a process model underlying said application is proposed in which said process model comprises a business process consisting of a plurality of activities to be performed on said application systems by a plurality of users, including shipping of activity requests between a local application system owning said business process and a plurality of remote application systems performing said activities with the help of a plurality of users. The basic idea is to optimize the assignment of the users to the appropriate application system in such a way that the number of remote work item requests is optimized. The inventional method can be advantageously applied to workflow management systems. The optimization process involved comprises applying a so-called ‘optimization function’ reflecting the overall costs for request shipping and additional costs for performing the business process.

摘要： The invention relates to a method and means of workload balancing for a multitude of applications servers. The method comprises a first-step, wherein an application client sends an application request to a request queue of a dispatcher. In a second step the dispatcher is extracting an application request from said request queue. Within the second step the dispatcher selects a certain one of the application servers to which the extracted application request is to be sent to based on a table. The table is administered by the dispatcher and the table comprises an indication of the workload of the application servers. Also within the second step the dispatcher administers the table according to the selection and the dispatcher sends the extracted application request to said certain application server. The method comprises a third step, wherein an application server after processing an application request returns to the dispatcher a response comprising an indication of its current workload. In a fourth step the dispatcher is administering the table according to said response.

摘要： Workflow management systems (WFMS) execute a multitude of process models including a network of potentially distributed activities. WFMS store WFMS state information on the process models, the process model instances currently executed by the WFMS, together with the instances's state and the state of the WFMS themselves, in Database Management Systems (DBMS). The WFMS engines encompassing a set of control functions are implemented directly within the DBMS. Only stubs corresponding to these control functions need be implemented within the WFMS. The stubs exploit the services of the control function cores within the DBMS. Such implementation architectures can increase performance of WFMS significantly as the control functions can operate on and within those computer systems which store the data on the WFMS state.

摘要： The present invention relates to a technique for controlling the creation of process instances within an execution environment such as a Workflow Management System. Upon receiving a request to create a process instance and corresponding input data to be processed by the process instance, a process instance identifier is first constructed for the process instance to be created based on the provided input. Next, the create request is executed, but only if no process instance exists or existed with the same process instance identifier. In the case where a process instance already exists or existed with the same process instance identifier, the present invention permits a user-defined action to be carried out to avoid an identifier conflict.

摘要： A system for improved scheduling of resources within a Workflow-Management-System or a computer system with comparable functionality (WFMS). Based on a new resource specification comprised within a process model and associated with an activity, the WFMS determines the resources required for execution of said activity. The invention further schedules a request for allocation of said resources on behalf and in advance of starting execution of said activity. This approach reduces the execution time of the activity as all resources required by the activity will be available when execution of the activity begins; the activity does not have to wait for these resources. Moreover, a WFMS knowing the required resources of the activities it is administrating is able to schedule resource requests to avoid resource conflicts between the activities.

摘要： Method and system for serializing access to datasets, suitable for use in a workflow management system which executes multiple business processes, wherein a single process instance is enabled to invoke web services which may update datasets of different storages holding redundant information. Business Process Execution Language for Web Services allows defining business processes that make use of web services and business processes that externalize their functionality as web services. As the business process has no knowledge about data that is accessed by invoked web services, concurrent process instances may update the same pieces of information within a database. Unless access to the data is carried out as a transaction, parallel execution of the process instances may cause data inconsistencies, which may be avoided by serializing tile execution of process in stances based on correlation information associated with messages consumed by the process instances.
摘要翻译：用于对访问数据集进行序列化的方法和系统，适用于执行多个业务流程的工作流管理系统，其中单个流程实例能够调用可更新保存冗余信息的不同存储的数据集的Web服务。用于Web服务的业务流程执行语言允许定义利用Web服务和业务流程的业务流程，将其功能外部化为Web服务。由于业务流程对于被调用的Web服务访问的数据不了解，并发进程实例可能会更新数据库中相同的信息。除非作为事务执行对数据的访问，否则流程实例的并行执行可能会导致数据不一致，这可能会通过基于与进程实例消耗的消息相关联的相关信息来序列化进程的进程的块执行来避免。

摘要： The present invention provides a computerized method for determining an addressee of a signaling request within a Workflow Management System or a computer system with comparable functionality (WFMS). Upon receiving a signaling request, which is providing a set of signal data elements, the current invention avoids the requirement that the signal data elements comprise any explicit specification of an addressee of said signaling request. To determine whether an event-activity of a process-instance being the instance of a process-model of a business-process is the potential addressee of the signaling request it is suggested to determine, whether the process-model comprises an event-identification-specification. This event-identification-specification according to the current invention is involving a subset of the signal data elements. Evaluating the event-identification-specification allows to indirectly decide if the event-activity is the addressee of the signaling request.
