    • An approach to power economization in a spoke and hub environment is presented. When a hub receives a data set from a first spoke, the hub writes the data set to a first partition that is associated with the first spoke. After the data transfer is complete, the hub powers down the first partition. If the first spoke sends additional data transfers to the hub while the first partition is powered down, the hub stores the additional data transfers in a second partition. When the first partition is powered up again, the hub moves the data intended for the first partition and that was stored in the second partition. The data is moved from the second partition to the first partition. The hub may monitor the size of the addition data transfers. If the data transfer is large, the hub may power up the first partition, write the data in the first partition, and move to the first partition any data that was intended for the first partition but written to the second partition while the first partition was powered down.
    • 介绍了辐射和枢纽环境中的电力节约方法。 当集线器从第一辐条接收数据集时,集线器将数据集写入与第一辐条相关联的第一分区。 数据传输完成后,集线器将关闭第一个分区。 如果第一个辐条在第一个分区断电时向轮毂发送额外的数据传输,则集线器将附加数据传输存储在第二个分区中。 当第一个分区再次通电时,集线器将移动第一个分区的数据,并存储在第二个分区中。 数据从第二个分区移动到第一个分区。 集线器可以监视添加数据传输的大小。 如果数据传输量较大,集线器可能会启动第一个分区,将数据写入第一个分区,并将第一个分区的数据写入第一个分区,并将第一个分区的数据写入第二个分区 关机

    • A method and system are provided for handling within a database system data items that are associated with data types that are not supported by the database language used to the database system. The data types are registered with the database system by storing, in the database, metadata that indicates the structure, physical layout, and constraints that apply to the data types. The database system uses the structure and physical layout information to access individual elements of data items. The database system validates data items using the constraint information, which includes constraints that dictate what values are valid for certain elements based on what values are supplied for other elements. Data items associated with many different data types may be stored in the same table. Applications can access the data items through a transformation view that transforms the data items from their native format to a format expected by the applications.
    • 提供了一种方法和系统,用于在数据库系统内处理与用于数据库系统的数据库语言不支持的数据类型相关联的数据项。 数据类型通过在数据库中存储指示应用于数据类型的结构,物理布局和约束的元数据来向数据库系统注册。 数据库系统使用结构和物理布局信息来访问数据项的各个元素。 数据库系统使用约束信息来验证数据项,约束信息包括根据为其他元素提供的值来指定哪些值对某些元素有效的约束。 与许多不同数据类型相关联的数据项可以存储在同一个表中。 应用程序可以通过转换视图来访问数据项,转换视图将数据项从本机格式转换为应用程序所期望的格式。

    • A method and apparatus are provided for allowing a resource manager to be more tightly integrated with foreign transaction managers with which it interacts through the use of an extensible framework of transaction and resource manager events. The tighter integration made possible by a framework in which personality modules are registered with resource managers. Each personality module corresponds to a particular foreign transaction protocol. Each personality module includes a mapping of key resource and transaction events to actions, where the action mapped to a particular event is the action required by the protocol in response to the event. When an event occurs within the resource manager, the resource manager performs the action mapped to the particular event by the appropriate personality module. For an event associated with a particular transaction, the transaction type associated with the transaction is used to select the appropriate personality manager, and the mapping within the personality manager is used to determine the appropriate action to perform. For an event associated with the resource manager, the corresponding actions in all of the registered personality modules are performed.
    • 提供了一种方法和装置,用于允许资源管理器通过使用可扩展的事务和资源管理器事件框架与外部事务管理器更紧密地集成在一起。 通过个人模块在资源管理器中注册的框架,更紧密的整合成为可能。 每个个性模块对应于特定的外部事务协议。 每个人格模块都包括关键资源和事务事件对动作的映射,其中映射到特定事件的操作是协议响应于事件所需的动作。 当资源管理器内发生事件时,资源管理器通过适当的个性模块执行映射到特定事件的操作。 对于与特定事务相关联的事件,与事务相关联的事务类型用于选择适当的人格管理器,并且使用个性管理器内的映射来确定要执行的适当操作。 对于与资源管理器相关联的事件,执行所有注册个性模块中的相应动作。
