Abstract: In a service system including client apparatuses for issuing a service request and server apparatuses for receiving a service request and providing service, there is provided a data relaying apparatus for relaying data communication between them. In response to a service request, the data relaying apparatus establishes a connection from the client apparatus to the server apparatus (destination). The data relaying apparatus relays data communication between the client apparatus and the server apparatus by using the established connection. The data relaying apparatus manages a number of connections established to each of the server apparatuses. In response to a service request, the data relaying apparatus accepts or refuses the service request so as to make a number of connections to the server apparatus equal to or less than a predetermined number, and notifies a user refused relaying of a service request that relaying is possible.

Abstract: A master management system includes a duty master creating part that counts the number of users in each group of same-attribute users who desire to use each of the applications, that identifies the applications each of which the number of users desiring to use is equal to or larger than a predetermined number, that creates and stores a master in a master management database of a storage device; and an individual setting part that identifies virtualization-possible applications of the applications each of which the number of users desiring to use is equal to or smaller than the predetermined number, and that sets data on users desiring to use the virtualization-possible applications in the distribution destination list of a distributing server.

Abstract: A storage management system for managing, in a computer system, access to a storage area for storing data, the computer system includes: a storage system that provides the storage area; a host computer system that mounts the storage area of the storage system via a network; and a maintenance system that performs maintenance for the storage area of the storage system, the storage management system includes: a mounting decision module that decides, according to a preestablished maintenance schedule, whether the host computer system is currently mounting the storage area of the storage system; a maintenance instruction module that instructs the maintenance system to execute the scheduled maintenance when the mounting decision module decides that the host computer system is not currently mounting the storage area; a host-on detecting module that detects a boot of the host computer system; a maintenance decision module that decides whether the maintenance system is currently performing the maintenance for the stor

Abstract: In an environment where there is a possibility that the user connects from a plurality of blade PCs to the storage, the present invention prevents the data destruction by realizing the exclusive control of the storage device. The storage connection from a blade PC which was possible to connect until now is made to be impossible by that the management server newly generates and sets to the storage device the connection information between the storage device which the blade PC keeps. Further, by sending the newly generated connection information to the other blade PC the connection from that blade PC becomes possible.

Abstract: A management device selects a storage device having a plenty of unallocated storage regions, selects a target using a port having a small allocation quantity from the storage device targets, and allocates the target, an initiator, and a storage region. When the number of targets and the allocated storage regions prepared by the storage device is within a predetermined number, the storage device manages the storage device as an allocation candidate. When the predetermined number is exceeded, the exceeding one is excluded from the allocation candidate. When the number of storage devices excluded from the allocation candidate has reached a certain number, the management device manages a new storage device and a new storage region as an allocation candidate.

Abstract: An information processing system has an information processing apparatus and a terminal that are coupled to each other through a network. The terminal has an address acquiring unit that reads storage information of a portable storage medium used by a user of the terminal to acquire the address of the information processing apparatus that is a utilization allocation destination of the terminal that is included in the storage information, and stores the data of the address in a memory. A connection is established between the information processing apparatus and the terminal through the network. A remote controlling unit transmits operating information input at an input interface of the terminal to the address of the information processing apparatus and receives video information corresponding to the operating information from the information processing apparatus to display the video information on an output interface of the terminal.

Abstract: An environment migration system set, as a utilization environment of a terminal, a utilization environment of another terminal in an information processing apparatus when the terminal utilizes the information processing apparatus through a network. A connection is established through a network between the information processing apparatus and the other terminal in accordance with response data returned from the information processing apparatus. A utilization environment transmitting unit extracts data of the utilization environment of the other terminal and transmits it to the address of the information processing apparatus. The utilization environment data received from the other terminal is then stored into a storage apparatus as the utilization environment data of the terminal.

Abstract: A search system that can easily search documents while ensuring the security is provided. A computer system includes one or a plurality of client devices, a search server, and a storage server connected to each other via a communication channel, and conducts search in response to a search request from one client device. The storage server stores a disk image that allows the client device to perform a boot operation via a network, thereby providing data search service to the client device.

Abstract: The request from the client to the server is made through the traffic control apparatus. The traffic control apparatus includes a unit for controlling the request from the client, a unit for judging the data reception performance of the client and a unit for controlling the number of clients simultaneously connected to the server. The number of simultaneous connections in the server is controlled so that the resource of the server can be utilized sufficiently and the requests in number exceeding the performance of the server cannot be transferred. When it is expected that it takes time longer than a fixed time to provide the service to be required to the client, the request is rejected and when it is expected that the service can be provided within the fixed time, the request is received.

Abstract: A load balancing system having a plurality of service servers and a load balancer which prevents a service performance from being reduced by an overload of requests on the service servers. The system includes a load balancer and a administration server, the load balancer outputs an access log relating to an access to the service server, and the administration server performs statistical operation over the access log. The administration server prepares a service server run schedule on the basis of a result of the statistical operation and informs the load balancer of it. The load balancer controls distribution of a request to the service server according to the informed run schedule.
