摘要： In order to execute a plurality of transactions using a plurality of computers connected in a network, a plurality of distribution arrangements are defined and stored in one of the computers, which acts as a management computer. Each distribution arrangement corresponds to a predetermined distribution of the transactions among the computers. One of the distribution arrangements is distributed to all the computers, and transactions executed on the basis of that distribution arrangement. Subsequently, a further distribution arrangement is distributed to the computers so that, when a suitable change-over conduction occurs, the transactions may be executed on the basis of the further distribution arrangement. The change-over condition may correspond to a particular time, failure of one of the computers, expansion of the network, or overload. In this way, the network may adapt to different circumstances without excessive processing being required.
摘要翻译：为了使用连接在网络中的多个计算机来执行多个事务，多个分配布置被定义并存储在用作管理计算机的计算机之一中。每个分配布置对应于计算机之间的事务的预定分布。分配安排之一分配给所有计算机，并根据该分配安排执行交易。随后，将进一步的分配布置分发给计算机，使得当发生适当的转换传导时，可以基于进一步的分布布置来执行交易。转换条件可能对应于特定时间，计算机中的一台故障，网络扩展或超载。以这种方式，网络可以适应不同的情况，而不需要过多的处理。

摘要： The present invention provides a non-stop data processing system having an online data backup function. The method according to the present invention is a data backup method for a computer system having a central processing unit for performing multitask processing, a multiple memory constituted by a plurality of memory devices for online storing data processed by tasks of the central processing unit, and a data backup memory for saving data of the multiple memory, wherein the central processing unit performs parallel processing of (a) user task(s) to treat usual work between the central processing unit and the multiple memory and a maintenance task to save data online from memory devices as a part of the multiple memory to the data backup memory. A data processing system according to the present invention is a data processing system having a central processing unit for performing multitask processing, a multiple memory constituted by a plurality of memory devices for storing data currently processed, and a data backup memory for saving data of the multiple memory, wherein: the central processing unit has (a) user task(s) to write currently processed data into the multiple memory, and a maintenance task to stop updating of memory devices as a part of the multiple memory and save data to the data backup memory; and the system further has an online interface whereby access to the respective memory devices of the multiple memory by the user task(s) and the maintenance task is relayed online.
