Abstract: A monitor function is implemented to monitor and control service processes and other system entities that perform tasks on a distributed network. The monitor function tracks the demise and instantiation of processes and entities that either export or import instrumentation. Any service process or other system entity (driver, interrupt handler, system library procedure) can export instruments (indicators, controls, testpoints). Instrument updates are propagated automatically if they are significant. The importing process conveys the information to a management system so that a human operator, or automated system, can observe and control the operation of the network service. One aspect of the invention uses a backup exporter to take over the processing of an exporter that has become nonfunctional. Another aspect of the invention determines when a CPU has gone down and acts accordingly to identify service processes that were associated with an exporter in the down CPU.

Abstract: A computer program product simulates shared code threads with Windows NT fibers. Computer code is included for reusing shared code threads which complete.

Abstract: A method of managing faults in a computer system including the steps of detecting an error, handling the error along a functional hierarchy and, further, handling a fault that caused the error in a management hierarchy which can be operated separately from the functional hierarchy.
