Configure Surveillance Policy

This service aid monitors the system for hang conditions; that is, hardware or software failures that cause operating system inactivity. When enabled, and surveillance detects operating system inactivity, a call is placed to report the failure.

Use this service aid to display and change the following settings for the Surveillance Policy.

Note: Some of the following settings may not be displayed by this service aid.

vSurveillance

vSurveillance Time Interval, in minutes

Maximum time between heartbeats from the operating system.

vSurveillance Delay, in minutes

Time to delay between when the operating system is in control and when to begin operating system surveillance.

vChanges are to take effect immediately

Set this to yes if the changes made to the settings in this menu are to take place immediately. Otherwise, the changes take effect beginning with the next system boot.

You can access this service aid directly from the AIX command line by entering:
