Sun OpenSSO Enterprise Policy Agent 3.0 Guide for Apache HTTP Server 2.2.x

Notifications

The Apache HTTP Server 2.2.x agent does not support notifications, so maintaining the agent's SSO, policy, and configuration caches through a notification mechanism is not available.

Therefore, do not enable notifications for the Apache HTTP Server 2.2.x agent, either in the OpenSSO Administration Console or by setting the com.sun.identity.agents.config.notification.enable property to true. Enabling notifications can cause unpredictable behavior for the agent.
