Changes to the Cache Model

The cache model for SiteMinder r12.0 SP3 differs from the model for 5.x:

• The Policy Store cache is no longer configurable.
• The L2 cache is replaced by self-tuning per-object-class caches.
• The User Authorization (AZ) cache size is configurable using the Policy Server Management Console. The cache can be tuned using the new counters available in the SiteMinder OneView Monitor.

Deploying SiteMinder Components

If you are deploying SiteMinder components on Windows 2008 SP2, we recommend installing and managing the components with the same user account. For example, if you use a domain account to install a component, use the same domain account to manage it. Failure to use the same user account to install and manage a SiteMinder component can result in unexpected behavior.
