摘要： A database manager, computer program product and methods for managing a database utilized by multiple applications. In one embodiment, the database manager performs a database record change to database records by a first application. The database manager branches the database records such that the database record change is visible to the first application and is not visible to one or more other applications accessing the database. The database manager can merge database record changes made by the other applications such that database schema changes made by the other applications are visible to the first application.

摘要： A method, system and computer program product for retrieving data records to a client computer. An identifier of a base query is received from the client computer. The base query is configured to select a set of data records from a database that the client computer has permission to access. A modifying clause is also received from the client computer. The modifying clause comprises a directive restricting the set of data records to a subset of data records. The modifying clause may optionally comprise an expression for sorting. A combined query is generated from the base query and the modifying clause. The query is configured to return the subset of data records. The combined query is further configured to sort the subset of data records based on the value of the expression if the expression is present. The combined query is executed at the database.

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来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。
