Abstract: Multiple-active database systems include at least two database systems that both store a common portion of a relational database. Each database system includes one or more data-storage facilities configured to store data forming the common portion of the relational database in one or more tables and one or more processing modules configured to manage access to the data in the data-storage facilities. One or more management components are configured to distribute database queries directed at the common portion of the relational database among the database systems and to synchronize the data across the database systems when changes are made to the data stored in at least one of the database systems.

Abstract translation: 多活动数据库系统包括至少两个存储关系数据库的公共部分的数据库系统。 每个数据库系统包括一个或多个数据存储设施，其被配置为将形成关系数据库的公共部分的数据存储在一个或多个表中，并且一个或多个处理模块被配置为管理对数据存储设施中的数据的访问。 配置一个或多个管理组件以在数据库系统中分配针对关系数据库的公共部分的数据库查询，并且当对存储在至少一个数据库系统中的数据进行改变时，跨数据库系统同步数据。

Abstract: A data-synchronization tool is used to ensure synchronization between at least two copies of a relational database that are stored in at least two database systems. The tool includes (a) a sync-control component configured to initiate synchronization of the copies of the database and (b) a sync-execution component configured to replicate one or more changes made to the copy stored in one of the database systems within the copy stored in another of the database systems.

Abstract translation: 数据同步工具用于确保存储在至少两个数据库系统中的关系数据库的至少两个副本之间的同步。 该工具包括（a）同步控制组件，被配置为启动数据库的副本的同步;以及（b）同步执行组件，被配置为复制对存储在其中一个数据库系统内的副本的一个或多个更改 复制存储在另一个数据库系统中。

Abstract: A system-management tool is used in managing at least two copies of a relational database that are stored in at least two database systems. The tool includes (a) a monitoring component configured to monitor for the occurrence of an event within one of the database systems that creates a change in an operational status of that database system, and (b) a synchronization component configured to update state information stored in another of the database systems to reflect the change in operational status of the one database system.

Abstract: A workload-management tool is used in distributing database requests across at least two database systems that both store copies of at least a portion of a relational database to which the database requests are directed. The tool includes one or more rules for routing database requests to the database systems and a routing component. The routing component is configured to receive an incoming database request, access the one or more rules for routing database requests to the database systems, and apply the one or more rules in selecting an appropriate one of the database systems to receive the incoming database request.

Abstract translation: 工作负载管理工具用于跨数据库系统分发数据库请求，这两个数据库系统都存储数据库请求所针对的关系数据库的至少一部分的副本。 该工具包括用于将数据库请求路由到数据库系统和路由组件的一个或多个规则。 路由组件被配置为接收传入的数据库请求，访问用于将数据库请求路由到数据库系统的一个或多个规则，以及在选择数据库系统中适当的一个数据库系统以应用传入的数据库请求时应用一个或多个规则。

Abstract: A system includes at least two database systems that both store a common portion of a relational database and that are configured to share in execution of a database workload against that relational database. The system also includes a system-management component configured to receive indication that a first one of the database systems is ceasing operation and, in response, take a second one of the database systems to an operational state in which at least a portion of the database workload that is scheduled to be carried out by the first database system is transferred to the second database system.

Abstract translation: 系统包括至少两个数据库系统，其两者都存储关系数据库的公共部分，并且被配置为在针对该关系数据库执行数据库工作负载时共享。 系统还包括被配置为接收数据库系统中的第一个停止操作的指示的系统管理组件，并且作为响应，使数据库系统中的第二个数据库系统处于操作状态，其中数据库的至少一部分 计划由第一数据库系统执行的工作负载被传送到第二数据库系统。
