Description
The Idle Time Resource Usage setting limits the maximum idle time allowed in a session. Idle time is a continuous inactive period during a session, expressed in minutes. Long-running queries and other operations are not subject to this limit. Setting an Idle Time Resource Usage limit helps prevent users from leaving applications open when they are away from their desks.

From SQL*Plus: select profile, limit from DBA_PROFILES where profile = ’DEFAULT’ and resource_name = ’IDLE_TIME’; select profile, limit from DBA_PROFILES where profile <> ’DEFAULT’ and resource_name = ’IDLE_TIME’; If the idle time on the DEFAULT profile is greater than 15 minutes, this is a Finding. If any non-default profiles have an idle time setting greater than 60 minutes or are set to an UNLIMITED value and not documented in the System Security Plan or not authorized by the IAO, this is a Finding.
