ABSTRACT:
An error recovery system for computers is shown in which an error table and an action table are used to control the parameters of the error recovery system. The error table has one entry for each possible error and contains a count increment for each corrective action that might be taken to correct that error. The action table includes an error count threshold for each possible corrective action. The system operates to accumulate error count increments against possible actions and, when the corresponding threshold is exceeded, initiates the corrective action. Since the table contents are easily modified, the recovery strategy can be updated and modified by the computer user without changing the recovery system programs.
