Fault recovery system and method for adaptively updating order of command executions according to past results
In a memory a number of entries are defined for mapping reference symptom levels of a server to fault restoration commands and to priority levels. In response to a status report from a fault detector indicating an operating state of the server, one of the commands is selected according to the priority levels corresponding to the reported state. The selected command is executed, and a result of the execution is estimated. In response to a subsequent status report, a comparison is made between the estimated result and an operating state indicated in the report. The priority levels are updated according to the comparison result. In a modification, status variables are mapped to the commands. A command is selected according to the status variables of entries to which a reported state corresponds. A success value is determined based on a result of execution of the command. The status variable of the selected command is updated with the determined success value.
