JP2003050753A - OPERATION SYSTEM FOR AUTOMATIC RECOVERY Web SERVER - Google Patents

Abstract

PROBLEM TO BE SOLVED: To automatically restore Web service when a problem is generated in a Web service, to minimize stop time of the Web service and to promptly communicate with a manager, when the Web service is stopped. SOLUTION: A Web client to automatically access a Web server is prepared, and an HTTP request is executed. When the problem exists in the Web server and timeout is generated, without being unable to completing the response of a WEB service part, the Web service is restored by restarting the Web server or an operation system. In addition, stoppage of the Web server is detected, by using a similar means and a message of the fact is communicated to the manager by using communication means, such as telephone, electronic mail. Thus, operations of the Web server is automatically monitored and restored. Consequently, this innovative Web server operation system enables continuation of the service by the minimum stop time, even if problems are generated in the Web server.

Description

Detailed Description of the Invention

[0001]
