Tech Tip : CA Single Sign-On : MaxSessionCacheSize ACO parameter is not working as expected 

Nov 15, 2017 06:59 AM

Issue:

For performance reasons, we are implementing the MaxSessionCacheSize ACO parameter to cache user sessions and avoid performing too many calls to Policy Server, however we are noticing the requests for newer users seems to not being cached correctly, and the Agent is calling the Policy Server too soon when the cache is full.

We would expect to see older user sessions to be removed in favor of the new ones.

Environment:

Policy Server R12.51 CR01 Web Agent R12.51 CR01

Cause:

There is a condition that causes the issue, as once the cache is filled, and a new entry needs to be added, the latest 10% of the cache entries are deleted.

Resolution:

This is fixed in R12.51 CR08, so upgrading Web Agent to this version will solve the issue.
