APTIDLE — Specifying the License Recovery Time
Specifies the license recovery time in seconds for concurrent (floating) licenses. This environment variable is disabled by default so that licenses for idle sessions will not be recovered. If idle license recovery is enabled, the default interval is 24 hours. The default interval may be changed by setting the APTIDLE environment variable on each client workstation. The minimum value for APTIDLE is 5400 (5400 seconds or 90 minutes).
To change the license recovery time to twelve hours (12*60*60):
setenv APTIDLE 43200
