I'd like to know what is the consequence of disabling Validation Period on a Realm configured for persistent session ?
Release: MSPPSF99000-12.51-Single Sign-On-Agent for Oracle PeopleSoft-MSP Component:
According to documentation, if you disable the Validation Period, the Web Agent will always try to validate the session from its cache and only call Policy Server if the session is not available in its cache.
On one hand, this should result in less calls to Policy Server and Session Store. On the other hand, this might lead to the fact that the Web Agent still validate the session, even if the session doesn't exist anymore in the Session Store.
Realm Dialog Reference
Be aware of the following:
For persistent sessions, the Idle Timeout must be enabled and set to a value higher than that specified for the Validation Period.
If enabled, determines the period that the Agent caches the result of a session validation call to the Policy Server. Session validation calls perform two functions: informing the Policy Server that a user is still active and checking that the user session is still valid. Session validation calls inform the Policy Server that a user is active and confirm that the user session is valid. If disabled, the agent always tries to validate the session from its cache and only calls the Policy Server if the session is not available in its cache.
To specify the validation period, enter values in the Hours, Minutes, and Seconds fields. If you are configuring the system to provide a Windows user security context, set this value high, for example, 15-30 minutes.
Note: The Validation Period value must be greater than zero.
Important! The session validation period must be less than the specified Idle Timeout value.
