Abstract
In the invention, an exception that occurs in execution of a program is detected, and the normal operation exception occurrence pattern and/or the exception occurrence distribution are prepared from detected exceptions. Furthermore, by comparing the exception occurrence pattern and/or the exception occurrence distribution with the exception that is detected in operation of a computer, the abnormal operation is detected in early stage.

7. A computer system comprising:
-
a detection means for detecting an exception that occurs concomitantly with execution of a program;
a memory means for storing a detected exception in time series; and

8. A program execution monitoring method for a computer system comprising the steps of:
-
detecting an exception that occurs concomitantly with execution of a program;
preparing an exception distribution table that shows the normal operation exception distribution from detected exceptions, and when an exception occurs in execution of the same program as said program;
comparing the distribution of the exception with said exception distribution table to judge whether the exception is an abnormal operation or not.
