Abstract
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.
