Problem Summary: The Oracle listener probe may timeout on a heavily loaded system, causing the Oracle listener to restart.
Workaround: On a heavily loaded system, the Oracle listener resource probe timeouts may be prevented by increasing the value of Thorough_probe_interval property of the resource.
The probe timeout is calculated as follows:
10 seconds if Thorough_probe_interval is greater than 20 seconds
60 seconds if Thorough_probe_interval is greater than 120 seconds
Thorough_probe_interval/2 in other cases
