The consistency between an application output destination and a permitted user for an I/O device section is ensured when a user deploys an application for processing and outputting input data onto an entrance node. The entrance node includes an output destination/user table that manages correspondence between an application output destination and a user. The output destination/user table stores information about the output destination used for each user who uses the entrance node. An application deployment management function of a processing section in the entrance node determines whether application deployment can be accepted from a user. To do this, the application deployment management function specifies a user corresponding to the output destination for the application from the output destination/user table and verifies that the user is consistent with a user permitted for an I/O device in the I/O device section used by the application.

Network node, information processing system, and method

Since no access history is generated for when a file update which makes use of a copy and paste function is performed, it is difficult to detect the file that served as the reference source during the update. Hence, the present invention is provided to manage a client access history for each file that is stored in a storage device, and detect a file, which has been accessed between a time when a corresponding user logs into the storage device and a time when an updated file is updated based on information of the access history, as the reference source for the updated file.

File detection device and method

A communication system in which, even when an HTTP session is disconnected from a mobile device, the HTTP session can be continued or a response from a Web server can be returned to a user, without installing a special application in the mobile device. A load-distributable system is provided for realizing such operation. To that end, in a communication system having a relay device that relays a request from a portable telephone terminal () to a Web server (), the relay device () relays a processing request from the portable telephone terminal () to the Web server, and stores a processing response from the Web server. The relay device () sends the portable telephone terminal a message to the effect that the processing response should be acquired from the relay device () or a message with the processing response added.

Relay device and program product, allowing continued communication via an alternative protocol

A management device connected to a file server providing a computer with file data stored in a storage subsystem, and collects information about access to the file data. In the management device, a log of access to the file data stored in the storage subsystem is collected as access data, and the access data for the same file data is grouped. With such a configuration, a large amount of information about access to the file data can be easily used, and the amount of information can be compressed.

Management device and computer system

In a distributed processing system including a plurality of programs distributed in a plurality of processing units and in which a program on reception side performs processing using a message transmitted from a program on transmission side, a management table for managing start of programs on reception side is provided in a processing unit in which the program on reception side is provided. A program utilizing the message transmitted from the transmission side is recognized and the recognized program is started at the start timing indicated in the management table. The start timing of the program set in the management table may be registered previously or the message may include information indicating the start timing.
