The following table describes the General tab parameters of Cluster-Wide Parameters:
Parameter Description
Policy result cache timeout Specifies the duration allowed in minutes to store the
role mapping and posture results derived by the
policy engine during a policy evaluation. This result
can then be used in subsequent evaluation of policies
associated with a service, if the Use cached Roles
and Posture attributes from previous sessions
option is turned on for the service. A value of 0
disables caching.
NOTE: The value of the Policy result cache timeout
field must be greater than the highest value set in the

example, if you have created the profiles Student-
Enforcement-Profile and Staff-Enforcement-Profile

of the Policy result cache timeout field must be
greater than the highest value of the Health Check
Quiet Period (in hours) value configured among the

pop-up:
'System is running with low disk space.
Aggressive cleanup will be initiated when the
available disk space falls below 80%. Current
available disk space = 75%'.

warnings are issued in the Policy Manager Event
Viewer. For example, a value of 30 indicates that a
