Set the Maximum User Session Cache Size

You can set a maximum for the number of users the Agent maintains in the session cache with the following parameter:

MaxSessionCacheSize

Specifies the maximum number of users the Agent maintains in its session cache. The session cache stores the session IDs of users who authenticate successfully. Authenticated users accessing other resources within the realm during a session, are authenticated using the session cache instead of the Policy Server. When the maximum number is reached, the Agent replaces the oldest user records with new user records.

Base the value of this parameter on the number of users that you expect to access and use resources for a sustained period. If you set this value to a high number, verify that sufficient system memory is available.

Note: Regardless of the cache size, all entries in the session cache of the Web Agent expire automatically after one hour.

Default: (Domino web servers) 1000

Default: (IIS and Oracle iPlanet web servers) 700

Default: (Apache web servers) 750

To set a maximum size of the user session cache

1. Set the value of the MaxSessionCacheSize parameter to the maximum number of users you want.
2. For framework agents, you must restart the web server to apply the change.
