Special caches for rarely changing objects

PolicyCenter includes specific individual caches for the following rarely changing objects:

• Exchange rates
• Groups
• Script parameters
• Zones

These specialized caches periodically refresh the entire set of the rarely changing object. This prevents the server from querying the database each time PolicyCenter accesses one of these objects, thereby improving performance. For each of these special caches, you can set the refresh interval through a configuration parameter in file config.xml.

The following table lists the objects with specialized caches, along with the configuration parameter that controls the refresh rate of each specialized cache.
