Software fault management system

A Software Fault Management (SFM) system for managing software faults in a managed mobile telecommunications network. The SFM system includes an Intelligent Management Information Base (I-MIB) comprising a Management Information Base (MIB) and a Knowledge Base (KB) having a functional model of the managed network and a trouble report / known faults (TR / KF) case base. The SFM system also includes an intelligent multi-agent portion having a plurality of agents which process the software faults utilizing the functional model from the I-MIB, case-based information, and other management information. The I-MIB and the intelligent multi-agent portion are compliant with Telecomunications Management Network (TMN) principles and framework. Fault management is both proactive and reactive. The SFM system is made independent of technology-specific implementations by representing the underlying switch design knowledge in a modular and changeable form which is then interpreted by the intelligent multi-agent portion. A clear separation is maintained between the generic procedural inference mechanisms and agents, and the specific and explicit models of the different network elements of a mobile telecommunications network.

Storage control device and data recovery method for storage control device

The present invention efficiently recovers an error drive by suppressing futile copying. When the number of errors of the disk drive is equal to or more than a first threshold, data stored in the disk drive is copied to a spare drive by a drive copy section. When the number of errors of the disk drive is equal to or more than a second threshold prior to completion of the drive copy, the disk drive is closed, and a correction copy by a correction copy section is started in place of the drive copy. The correction copy section starts the correction copy from the position where the drive copy is interrupted by taking over the drive copy completion position (copy interrupt position) managed by a copy progress condition management section.

Web controls validation

Web control validation may be defined using one or more declarations that are included in an ASP+ file by the web page author. The declarations specify server-side objects that validate the input data received in the web page and provide error handling in the event of a validation failure error. Validation declaration parameters specify the validation criteria against which the input data is validated. Example validation operations involve regular expressions, required fields, data comparison, range comparison and custom validation. Validation parameters can also specify- either server-side validation or client-side validation, depending on the client browser's capabilities. In a server-side scenario, a server-side validation object processes the input data received in an HTTP request from the client. In a client-side scenario, a server-side validation object renders the appropriate client-side code to validate the input data without a round trip between the client and the server.

Adaptive timeout value setting for distributed computing environment (DCE) applications

An adaptive timeout value setting is determined for DCE applications, wherein the timeout value setting is adapted and adjusted according to environmental factors and communication conditions between a client / server pair. The adaptive timeout value setting takes into consideration the communication time between a client and a server in each client / server pair in determining and setting a timeout value for each pair. The timeout value for a client / server pair is adjusted in a dynamic fashion so that the client is able to be more adaptive to real environment changes and so that the server's performance is not degraded due to ineffective timeouts. The system and method determines an adaptive timeout value setting in distributed computing environment (DCE) applications for a client / server pair wherein each pair has a client system and a server system. A server response time of the server system is tracked to a remote procedure call from the client system. The remote procedure call includes a binding handle, and the server response time is based on a time of the server system responding to the remote procedure. An optimal timeout value is calculated from the response time, and a timeout value of the binding handle is reset as the optimal timeout value.
