Abstract: A process, a tool and a computer for analyzing and locating hardware failures in a computing machine storing information on operational errors generated by the various sensible hardware components of the machine, characterized in that it consists of creating a man/machine interface (I) through which the components and the rules for interpreting errors are described in a structural language and used by the machine as external parameters in correlation with the error information to detect the malfunctioning component or components. The preventive process is particularly adopted for computer hardware maintenance.

Abstract: The invention relates to a method of correction of corrupted data stored in a memory location by scrubbing. The memory is associated with an error correcting code device which corrects the data transmitted to a user requesting them. The method comprises three steps. During a first step, the data is read from the memory at an address contained in a first register, corrected, and stored into a second register. A reservation is created. During a second step, if a reservation exists the data contained in the second register is written back into the same memory location. The reservation is cleared and a particular field of a condition register is modified. If a reservation does not exist, the second step is completed without altering the memory location. During the third step, the status of the condition register is checked. If the test is positive the process is ended, the scrubbing being successful; if not, an iteration of the three above steps is executed.

Abstract: The present invention relates to a process and system for real-time monitoring of a data processing system for administration and maintenance support of the data processing system in the operating phase, which data processing system communicates in a client/server mode through interconnected networks (W), each client (WCL) comprising a browser (BRO) which supports a high-level hypertext language. Intelligent agents are installed in each server (WSE) for running, after the phrasing of client requests, a check on the status of each server, measuring and storing parameter information indicating the status and the behavior of the server at a given moment, which parameter information is automatically collected as a function of domains examined and systematically processed by the server so as to be offered in the form of presentation reports contained in dynamically evolving pages while the client's browser accesses the dynamic pages having the collected and processed information responding to a request.
