A reserved request type of searched information distribution server having a first function unit for issuing a search request to another server connected to the Internet via the Internet so as to collect desired data from a WWW server specified by the search request according to a schedule specified by the search request when receiving request of data searching in a WWW server from a client terminal, and a second function unit for receiving searched data via a communication satellite.

A messaging processing system which includes a process control table for storing the control information of a process corresponding to access terminals connected through a public network in a form that identifiers indicating the 'priority processing' are added to the control information, and a scheduler that executes the process having the identifier indicating the 'priority processing' in preference to the other processes during the dispatching processing of the process.

Messaging processing system and method

An error recovery reduces the recovery time in finding out the JOB causing error in a computer system. An event generation unit is called at the beginning of the execution of a JOB, at the end of the execution of the JOB and at the close process of the file input-output process, by the JOB execution control unit. The JOB start event, end event, and close event are generated by the event generation unit. A file input/output count acquisition unit is called to generate a file input/output count for each JOB, by the JOB execution control unit. The monitoring process thereby generates the execution record comprising the end code, the start time, the end time, the execution time, the file input/output count, and the error flag for each JOB, based upon the above mentioned events. The monitoring process activates the error recovery support process when the error occurs. The error recovery support process compares the execution record with the standard record based upon the normal execution, checks for an abnormality of the input/output count, the execution time and the end code, stores the abnormal flag into the execution record, and sets the JOB generating the abnormality as the JOB causing error. The operator instructs to re-execute the JOB after the recovery and reallocation of the file.

Control method and apparatus for dynamically switching a logical session

User authentication information for network of a user and a name of a server to be accessed are sent from a client terminal to a user management equipment realized by one of servers which constitute a network system. The user management equipment sends the network address of that server and user authentication information registered for that server back to the client terminal. Using these pieces of information, the client terminal logs in that server. Each of the servers used by the user notifies the user management equipment of the actual accounts for the user at preferable times. Using the notified information, the user management equipment manages the actual accounts of each user. Each user can know the total of actual accounts for the servers used by accessing only the user management equipment.

Method of assisting server access by use of user authentication

In an electronic mail associated type computer system network equipped with a computer system for executing a job and a general-purpose electronic mail system, a user of an electronic mail can freely recognize a condition of an execution result of a job performed in the computer system and a job execution result. Also, these results are available from a desired output device for the user. When a mail processing unit employed in the computer system analyzes a mail statement about the job execution derived from the electronic mail system, and the job execution is completed, this mail processing unit sends to the electronic mail system, such a mail statement for the completion of the job execution containing information about fail/safe execution result. Upon receipt of this report, the user designates the output device into a response mail so as to output the job execution result from the designated output device.

Computer system and job transfer method using electronic mail system

In an arrangement of a mail terminal 1, an electronic mail system 2, a job control terminal 4, and a computer system 3, a user makes a proposal of a file operation via a mail by way of the mail terminal 1. The electronic mail system 2 stores therein the proposal mail, exchanges this proposal mail with the job control terminal 4, and furthermore distributes a file operation result to the respective mail terminals. The job control terminal 4 receives a mail from the electronic mail system 2, and interprets the proposal mail, thereby executing a conversion from a mail ID into a host ID, a judgement of an access authorization with respect to the designated file, and a production of an instruction to the computer process system 3. Furthermore, an execution host computer is selected by monitoring operation conditions of the host computers. When the file operation result is sent from the computer process system 3, a mail containing this file operation result is produced, and the resultant mail is sent to the electronic mail system 2. The computer system 3 interprets a command issued from the job control terminal 4, thereby executing a reading operation from the designated file, a writing operation to the designated file, and a reading operation of a file name list.
