Abstract: When a failure occurs in an LPAR on a physical computer under an SAN environment, a destination LPAR is set in another physical computer to enable migrating of the LPAR and setting change of a security function on the RAID apparatus side is not necessary. When a failure occurs in an LPAR generated on a physical computer under an SAN environment, configuration information including a unique ID (WWN) of the LPAR where the failure occurs is read, a destination LPAR is generated on another physical computer, and the read configuration information of the LPAR is set to the destination LPAR, thereby enabling migrating of the LPAR when the failure occurs, under the control of a management server.

Abstract: As regards a hardware fault which has occurred in a computer, a hypervisor notifies an LPAR which can continue execution, of a fault occurrence as a hardware fault for which execution can be continued. Upon receiving the notice, the LPAR notifies the hypervisor that it has executed processing to cope with a fault. The hypervisor provides an interface for acquiring a situation of a notice situation. It is made possible to register and acquire a situation of coping with a hardware fault allowing continuation of execution through the interface, and it is made possible to make a decision as to the situation of coping with a fault in the computers as a whole.

Abstract: A virtual machine system in which a physical CPU busy ratio can be measured in consideration of the status of an assignment of the physical CPU, and the measured CPU busy ratio can be reflected to a CPU busy ratio of each guest OS. An elapsed time counter is provided in a hypervisor, and a hypervisor access interface is provided in each of LPARs and used to read the elapsed time counter from the guest OS. A performance monitor program running on each guest OS calculates, based on a value of the elapsed time counter, the number of sampling timings expected to occur during the time when the physical CPU is not assigned to the LPAR in which the performance monitor program is provided.

The management server acquires respective authentication information items corresponding to the at least two processing identifiers contained in the received acquisition request from a second storage unit, and transmits the acquired authentication information items to the proxy server. The proxy server transmits user authentication requests for respective processing systems containing the received authentication information items to the at least two processing systems, respectively.

Abstract: One system distributes a request for providing a service using a first communication protocol, from a terminal device to a server selected from among a plurality of servers by a server load balancer in response to the request. A corresponding relation between identification information for identifying a session generated in a distributed server and the server that has generated the session corresponding to the identification information is set in the server load balancer by the service of a second communication protocol as uniqueness assurance information for uniqueness assurance. Thus, when the provision of a service is requested using a second communication protocol by the terminal device, the server load balancer refers to the set uniqueness assurance information and selects the server for providing the service from among the plurality of servers.

Abstract: A relay server receives from a mobile terminal a delivery request to a delivery server device that provides an application to the mobile terminal. The relay server obtains position information of the mobile terminal from a representative device connected to a position managing server that holds the position information of the mobile terminal. The relay server transmits the position information of the mobile terminal obtained from the representative device to a relay device that relays a communication to inquire about the position information of the mobile terminal to the representative device. The relay server updates the position information obtained from the representative device with the position information received from the relay device when the position information of the mobile terminal is received from the relay device. The relay server transfers the received delivery request to the delivery server device identified based on the updated position information.

Abstract: A switch (50) is adapted to be On when a contact point (52) is at a position to be in contact with a cam surface (47) and Off when the contact point (52) is at a position corresponding to a non-cam surface (48). In the vicinity of the non-cam surface (48) of the cam surface (47), a rib (49) is provided which changes a direction of the contact point (52) when reciprocation of the cam member (43) is changed. Accordingly, even when the switch (50) comes into contact with the cam member (43) moving in a different direction, the direction of the contact point (52) is changed so as to be the same. Hence, the switch (50) is prevented from being affected by a hysteresis caused by difference in directions of the contact point (52).

Abstract: A load balancing apparatus stores a transfer rule in which a path control identifier for identifying a path for a message sent from a client device is associated with relay device information for specifying a relay device that creates the path control identifier. When receiving a message from the client device, the load balancing apparatus determines whether the message contains the path control identifier. If the load balancing apparatus determines that the path control identifier is contained, the load balancing apparatus specifies, from the transfer rule, relay device information with which the path control identifier is associated and then sends the message to a relay device that is specified by the specified relay device information. In contrast, if the load balancing apparatus determines that the path control identifier is not contained, the load balancing apparatus sends the message to the relay device specified in accordance with a predetermined condition.

Abstract: The tray of the disc device includes the ground member including the base cover that substantially covers the electronic component and the ground extension portion, and the front projection located forward in the tray-out direction relative to the ground extension portion. The casing includes the casing-side ground contacting portion that contacts the ground extension portion in a tray-in state. In the tray-in state, the ground extension portion and the casing-side ground contacting portion are contacted so that static electricity is flowed to the casing via the ground member, thereby preventing the static electricity from flowing and damaging the electronic component. Even when the ground extension portion is deformed in the tray-out direction, the contact between the ground extension portion and the front projection prevents excessive deformation of the ground extension portion. Thus, the disc device can be easily handled without fearing damage to the ground extension portion.
