The full discovery interval is counted from the time when the IP Manager is started. So, if the full discovery interval is set to 1 day and the IP Manager is started at 5 A.M., the full discovery will occur each day at 5 A.M.
The ICF-TopologyManager program for the IP Manager starts a full discovery every full discovery interval unless the previous full discovery is still in progress, in which case the ICF-TopologyManager ignores the discovery request and writes an exception to the IP Manager’s log file. For example, if the full discovery interval is set to 1 hour and the actual full discovery takes 1.3 hours to complete, the ICF-TopologyManager will ignore the discovery request every other discovery interval, which means that the actual full discovery will occur every 2 hours.
To specify a scheduled full discovery interval other than 1 day:
Attach the Domain Manager Administration Console to the target IP Manager.
“Opening the Domain Manager Administration Console” on page 18provides instructions on opening this console.
In the left panel of the Domain Manager Administration Console, click the IP Manager name to display a multiple-tab window in the right panel of the console.
Type a value in the Interval field for full discovery and select a time interval (Seconds, Minutes, Hours, or Days) from the list box. Ensure that the interval is equal to or greater than 60 minutes.
As an alternative to using the Domain Manager Administration Console to specify a full discovery interval, you can use the cron or sm_sched scheduler and the dmctl or sm_tpmgr command to schedule a full discovery at a specific time. Examples of dmctl and sm_tpmgr commands to initiate a full discovery are given in “Starting discovery from the command line” on page 88.
If you use cron or sm_sched or some other scheduler utility to schedule full discoveries, clear the Enable Full Discovery checkbox in the Domain Manager Administration Console.
