A resource management system including a plurality of computer systems and providing services through operations of task applications by combining the plurality of the computer systems, which comprises: a storage which is included in at least one of the computer systems for storing information for identifying the computer systems which execute the task applications, respectively, and resource utilization rate information which includes utilization rates of resources configuring the respective computer systems; and an effected range investigation unit which is included in at least one of the computer systems and obtains utilization rates of additional resources required by a task application from the resource utilization rate information when the effected range investigation unit obtains information that the task application requires the additional resources of the computer systems; and sums utilization rates of resources configuring newly configured computer systems.

System and method for managing resources

A data-processing system has at least one computer executing at least one application program and at least one storage device. The computer and the at least one storage device storing data are communicatively connected via a plurality of data transfer paths assigned to each program. A data-processing apparatus is communicatively connected to the data-processing system. The data-processing apparatus includes a system configuration storage unit, an abnormality detection information reception unit, an inspection target selection unit and an inspection result storage unit. The system configuration storage unit stores, in a correlated manner, each component of the data-processing system constituting each data transfer path and a program using each component as a data transfer path. The abnormality detection information reception unit receives abnormality detection information indicating that an abnormality is detected while executing an application program, from the computer. The inspection target selection unit selects an inspection target among the each component as a component correlated with the largest number of application programs. The inspection result storage unit stores a result of inspection for a component selected as the inspection target.

Method and system for managing programs in data-processing system

In a hierarchical network configuration, if transfer of data, such as requirements and responses therefrom and thereto, are executed in a relay manner between plural manager systems and managed systems on network routes, the requirements and the responses are duplicated in each manager system, thereby presenting a problem of increased amounts of data transfer on the network. It is possible to prevent the data transfer amounts from increasing not only on one route but also on plural routes by determining whether to update data on the basis of names of a manager system in upper layers, route information and so forth.

Data transfer method, apparatus, and recording medium for use in hierarchical system

A terminal to be remote controlled via a communication network is provided with a communication controllerA for receiving a remote operation message from a control terminal, a remote operation basic controllerA for delivering remote operation input data extracted from the received message to an operating system, and an operation recording and playing controllerA for recording and playing the remote operation input data and specific terminal operation data as remote operation history data.

Method and apparatus for remotely controlling a terminal by a control terminal and storing control history information at the terminal being remotely controlled
