An information processing apparatus having a resume function which can maintain the security even when a plurality of users commonly use the apparatus. A work state at a power-off time of the apparatus is preserved together with a work state name including a user's ID in a different area in a plurality of preservation areas for resume function on a main memory for each user. When a power source is again turned on, data in the preservation area corresponding to the user's ID is used to reproduce the work state of the user at the power-off time. The work preservation areas can be provided on a file server apparatus in a network not needing battery back-up. When the information processing apparatus is used, a work state at a power-off time can be independently preserved and reproduced for each user.

Distributed database management system including logical database constituted by a group of physical databases

An information processing apparatus having a resume function which can maintain security even when a plurality of users use a common information processing apparatus. A work state at a power-off time is preserved together with a work state name including a user's ID in a different area in a plurality of preservation areas for the resume operation function on a main memory for each user. When a power source is turned on again, data in the preservation area corresponding to the user's ID is used to reproduce the work state of the user at the power-off time. A work state preservation file on a file server apparatus in a network has a resume function which does not need battery back-up. When this information processing apparatus is used, a work state at a power-off time can be independently preserved and reproduced for each of users, thereby realizing a resume function that is excellent in terms of security and utility.

Information processing apparatus with resume function and information

Parameters representing types of machines to be connected to a network, connection types thereof to the network, and operation modes thereof in the network system are set from an information processing apparatus. The obtained parameters are written as parameter files on a recording medium. In each network machine, a network system is automatically constructed by referencing the files. Consequently, the parameter setting operations for the installation of the machine are simplified and there is achieved automation of operations in each network machine.

Network integrated construction system, method of installing network

A database access system for a distributed system, in which the database access load is distributed among a plurality of gateways, and an arbitrary character code set can be used for database access. After the lapse of a predetermined time length, processings for particular database access are terminated. An error of a DBMS or a component on the gateway is detected by a client. The gateway detects an error of the client in connection. The client notifies the character code set identification information of the character code used for outputting the request to the gateway, and the gateway converts the character code for the request and a response to the client. The gateway receives an access request, secures the connection with a database access language conversion unit, and sends the language converted to a DBMS. In the absence of a response after the lapse of a predetermined time length, the connection with the database access language conversion unit is terminated and an error is notified to the client. Also, an error monitor request is outputted at regular intervals of time, and an error is notified to the client in the case where there is no response to the error monitor request after the lapse of a predetermined time length.

A power consumption control apparatus for an information processing apparatus having multi-tasking control which executes a plurality of information processing operations in parallel by time-divisionally switching a plurality of tasks in an arithmetic processing unit. The power consumption controlled apparatus detects an event where there are no information processing operations to be executed, sets the arithmetic processing unit to a power-saving mode in response to the event and immediately clears the power-saving mode set in the arithmetic processing unit in response to an interrupt signal from an input/output device. Alternatively, the power consumption control apparatus after detecting the event stops supply of a clock to the arithmetic processing unit or lowers a frequency of the clock in response to the event. Thereafter, the power consumption control apparatus immediately resumes supply of the clock to the arithmetic processing unit or raises the frequency of the clock in response to an interrupt signal from an input/output device.

Power consumption control system

An information processing system in which update processes are automated in conformity with types of client machines, to thereby dispense with manual version update processes, and within which redirectors of identical version are run at any time, to thereby prevent any error ascribable to different programs from occurring. When a redirector stored in the client machine is started, it notifies version information of its own to a configuration management program stored in a server machine. In a case where version information of a redirector stored in a configuration management database is newer than the notified version information, the configuration management program sends an update request back to the redirector of the client machine and transfers the new redirector to the client machine so as to update the redirector thereof.

Information processing system having a configuration management system

A system having at least one information processing apparatus such as a word processor and a printing apparatus as a print server for printing print data which is given from the information processing apparatus using print programs. When the print data which the information processing apparatus itself has is printed by the printing apparatus, the information processing apparatus transfers a print program suitable to print the print data to the printing apparatus, so that the printing apparatus prints the print data by using the print program transferred. In the case where a plurality of data are stored in a memory apparatus in the print server, the data is outputted to the printing apparatus in accordance with a predetermined order. However, when the print server receives an output request of the data from the information processing apparatus from the information processing apparatus, in the case where there is no data which is being outputted to the printing apparatus or whose output is waited, the output requested data is supplied to the printing apparatus without being stored into the memory device.

Output control method and system of servers

Computer controlled method and system capable of preserving information

A facsimile server system which can be utilized similarly to a stand-alone FAX. A remote FAX includes a scanner, a printer and a FAX communication unit. A client delivers document data to a FAX server, and makes a request for FAX transmission/printing. The FAX server expands the document data requested to be transmitted, into image data, and it transfers the image data to the appropriate remote FAX and gives a command for the FAX transmission/printing. When instructed to perform FAX transmission directly by a user, the remote FAX accepts the image of a handwritten document, and it subsequently delivers the image data of the document to the FAX server and makes a request for the FAX transmission. Besides, when the remote FAX has been commanded to scan image data or has received image data as FAX reception, it delivers the scanned image data or the received image data to the FAX server. Then, the FAX server accumulates the image data and offers them to the client in accordance with a retrieval process.
