摘要： An on-demand manager provides an improved distributed data processing system for facilitating dynamic allocation of computing resources among multiple domains based on a current workload and service level agreements. Based on a service level agreement, the on-demand manager monitors and predicts the load on the system. If the current or predicted load cannot be handled with the current system configuration, the on-demand manager determines additional resources needed to handle the workload. If the service level agreement violations cannot be handled by reconfiguring resources at a domain, the on-demand manager sends a resource request to other domains. These other domains analyze their own commitments and may accept the resource request, reject the request, or counter-propose with an offer of resources and a corresponding service level agreement. Once the requesting domain has acquired resources, workload load balancers are reconfigured to allocate some of the workload from the requesting site to the acquired remote resources.
摘要翻译：按需管理器提供改进的分布式数据处理系统，用于基于当前工作负载和服务级别协议，促进多个域之间的计算资源的动态分配。根据服务级别协议，按需管理器监视和预测系统上的负载。如果当前或预测的负载不能用当前系统配置来处理，则按需管理器确定处理工作负载所需的额外资源。如果通过在域上重新配置资源不能处理服务级别协议违规，则按需管理器向其他域发送资源请求。这些其他领域分析自己的承诺，并可以接受资源请求，拒绝请求或反提出资源提议和相应的服务级别协议。一旦请求域已经获得资源，工作负载平衡器被重新配置以将一些工作负载从请求站点分配给所获取的远程资源。

摘要： A method for programming and executing long running transactions between interface devices and a server includes the steps of providing a predicate set and a transform set on the interface devices pursuant to an activity to be performed by the long running transaction, the predicate set defining conditions for which updates to states in accordance with the activity are to be made and the transform set for applying the updated states pursuant to the predicate set, committing the activity for processing upon establishment of communication with the server from the interface device, establishing communication with the server from the interface device to initiate the long running transaction, replaying the predicate set and the transform set for the server to determine if the long running transaction is capable of being committed on the server and if capable of being committed on the server, committing the long running transaction to update states of the server wherein a plurality of interface devices are capable of executing long running transactions concurrently while competing to update states of the same data on the server and while maintaining transactional consistency. A system for programming long running transactions is also disclosed.

摘要： In a data processing environment where a client requests a server to perform part of its processing, a method of updating the client's version of server-related data without requiring the client to be a server, includes steps of: receiving, at a control point server, a first request from the client requesting that server-related data be transferred from the control point server to the client; and in response to the first request, sending the server-related data from the control point server to the client, along with a unique bind token identifying a version number of the server-related data such that each time the server-related data changes a new unique bind token is associated with the data, where the client uses the server-related data to form a second request for the server to perform part of the client's processing, and where the client sends said bind token to the server as part of the second request.

摘要： A system and method for a general and extensible infrastructure providing monitoring and recovery of interdependent systems in a distributed/clustered system is disclosed. Subsystems, built without provision for high availability, are incorporated into the infrastructure without modification to core subsystem function. The infrastructure is comprised of one or more computing nodes connected by one or more interconnection networks, and running one or more distributed subsystems. The infrastructure monitors the computing nodes using one or more heartbeat and membership protocols, and monitors the said distributed subsystems by subsystem-specific monitors. Events detected by monitors are sent to event handlers. Event handlers process events by filtering them through activities such as event correlation, removal of duplicates, and rollup. Filtered events are given by Event Managers to Recovery Drivers which determine the recovery program corresponding to the event, and executing the recovery program or set of recovery actions by coordination among the recovery managers. Given failures of said event handlers or recovery managers, the infrastructure performs the additional steps of: coordinating among remaining event handlers and recovery managers to handle completion or termination of ongoing recovery actions, discovering the current state of the system by resetting the said monitors, and handling any new failure events that may have occurred in the interim.
