Abstract: A system for performing a setting of a program downloaded from a server to a client is provided, which includes: a communication device performing data communications between the server and the client; and a storing device storing a predetermined program and a plurality of sets of setting information for the predetermined program, in which the server includes: a first receiver section receiving specifying information sent from the client via the communication device for specifying the setting information; and a first transmitter section reading out from the storing device the predetermined program and the setting information specified by the specifying information received from the client, and sending these to the client that is the origin of the specifying information via the communication device, and in which the client includes: a second transmitter section sending the specifying information to the server via the communication device; a second receiver section receiving the predetermined program and the se

Abstract: In a trading data management system including a plurality of clients and a web server connected to the clients via a communications network, when an interruption occurred while the server is receiving data traded in a client for some reason or other, the system restores data that had been transmitted from the client to the server before the interruption of the transmission occurred. The system includes: a unit that receives data traded in one of the clients every time the data is transmitted from the client to the web server; a storage unit that stores the data in a DB server connected to the web server; a unit that determines whether the reception of the trading data has been completed or not; a unit that informs the client that the trading data has not been completely received when the determining unit has determined so; and a unit that returns data stored in the storing unit to the client when the determining unit has determined that the trading data has not been completely received.

Abstract: An information processing system and an information terminal thereof and, in particular, an information processing system and an information terminal thereof are provided in which business work can be continuously performed via an external network, such as the Internet, by co-operating with a high-ranking host computer even during a failure. In an information processing system in which the information terminal communicates with the information processor in an external IP network via a main circuit for normal use or a secondary circuit for use when a failure occurs, provided with the router, the information terminal has a communication failure detecting means to detect a communication failure at an application level during communication with the information processor, and route switching instruction means to instruct to the router to switch from a main circuit to a secondary circuit by detecting the communication failure.
