Abstract
An error recovery subsystem which can be easily modified for use with any physical hardware which is being monitored is disclosed. The error recovery subsystem employs a user editable file including the rules for defining the system state, the error states, and the sequences of recovery actions to be taken depending upon the comparison between the system state and the error states. The rules for defining the system state, include don't care variables, and the sequences of recovery actions are specified using an index into a set of elemental recovery actions. Because the system state, error state, and sequence of recovery actions are defined in a user editable file modifications to the error recovery scheme can be made without recompiling the error recovery subsystem program code. Such modifications to the error recovery subsystem may therefore be made on a real time basis. A method for recovering from an error and a program product therefore are also disclosed.
