It is recommended that you configure and manage system defaults using the Global Manager Administration Console. If you must check the current System Default values using dmctl, note that these parameters are configured in the ICS_NotificationFactory in the following example:
Properties of ICS_NotificationFactory::ICS-NotificationFactory:
CreationClassName = ICS_NotificationFactory
Description =
DisplayName =
Name = ICS-NotificationFactory
ServiceName =
aggregateClass = ICS_Notification
defaultAuditTrailSizeLimit = 100
defaultAutoAcknowledgmentInterval = 301
defaultInactiveAutoArchiveInterval = 14402
notificationClass = ICS_Notification
notificationPrefix = NOTIFICATION-
Therefore, you could use the following dmctl command to get the InactiveAutoArchiveInterval for your currently running SAM domain:
./dmctl -b <Broker> -s <SAM_Domain> get ICS_NotificationFactory::ICS-NotificationFactory::defaultInactiveAutoArchiveInterval
