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.

Use of hashing function to distinguish random and repeat errors in a memory system
One embodiment provides an error detection method wherein single-bit errors in a memory module are detected and identified as being a random error or a repeat error. Each identified random error and each identified repeat error occurring in a time interval is counted. An alert is generated in response to a number of identified random errors reaching a random-error threshold or a number of identified repeat errors reaching a repeat-error threshold during the predefined interval. The repeat-error threshold is set lower than the random-error threshold. A hashing process may be applied to the memory address of each detected error to map the location of the error in the memory system to a corresponding location in an electronic table.

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.

InactiveUS6526433B1Hardware monitoringMultiple digital computer combinationsValue setDistributed Computing Environment
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.
