Abstract

In a data processing system formed of a plurality of nodes each connected to networks, each node operates either as a manager or as an agent. The manager supervises information included in the agents which are managed by the manager itself. A super manager is connected to the network for recognizing the node which operates as the manager which performs double supervision of the information in the agents with the manager. The super manager has a receiving unit for receiving information to be supervised by the node which operates as the manager, a detecting unit for detecting a failure of the node which operates as the manager, and a supervising unit for specifying information to be supervised by the faulty manager in accordance with information received by the receiving unit when the detecting unit detects the failure. The super manager supervises the object information to be supervised instead of the manager when the manager fails.

Claims8

Dependent claims

A data processing system having a plurality of nodes each connected to at least one network, each node operating either as a manager node or as an agent node, each manager node being adapted to supervise information included in a set of agent nodes which are assigned to the manager node, said system comprising:

a super manager connected to the at least one network for recognizing the nodes which operate as a manager node, and for performing double supervision, of information in the set of agent nodes assigned to each manager node,
the super manager further comprising,
a receiving means for receiving information to be supervised by each manager node,
a detecting means for detecting a failure of a manager node, and
a supervising means for specifying information supervised by a manager node which has failed in accordance with information received by the receiving means when the detecting means detects the failure, and for supervising the specified information instead of the manager node which has failed.
