Computer system with polymorphic fault processing
First Claim
1. A prerecorded data storage medium comprising:
- a. a data storage medium; and
b. indicia recorded on the medium, the indicia comprising instructions, in a program for a first computer, for;
recognizing a fault signal provided by a fault monitor of a second computer;
instantiating a polymorphic fault object in response to the fault signal, the polymorphic fault object comprising a data structure that identifies a fault processing method; and
dynamically binding the fault processing method to the program in response to the data structure in order to reduce recurrence of the fault signal.

Abstract
A computer system includes a main processor and a supervisory processor. The main processor provides status signals when a fault condition exists and responds to control signals for fault recovery. The supervisory processor instantiates objects from a fault class in response to the status signals. Objects are polymorphic in that each object has substantially the same methods available at its interface though each object corresponds to a different fault. Methods accomplish fault recovery by providing the control signals. System operation exhibits fewer errors by the supervisory processor and system expansion is more easily accommodated with greater reuse of proven program code than possible with prior supervisory processor software.

10. A prerecorded data storage medium comprising:
-
a. a data storage medium; and b. indicia recorded on the medium, the indicia comprising instructions, in a program for a first computer, for; recognizing a first fault signal and a second fault signal, each fault signal provided by a fault monitor of a second computer; instantiating a first polymorphic fault object in response to the first fault signal, the first polymorphic fault object comprising data identifying a first component of the second computer; instantiating a second polymorphic fault object in response to the second fault signal, the second polymorphic fault object comprising data identifying a second component of the second computer, the second component being of a different type than the first component; and dynamically binding the first polymorphic fault object and the polymorphic second fault object to a fault processing method to reuse the fault processing method. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
