This section provides a list of software and hardware configuration restrictions that apply to Sun Cluster HA for Apache Tomcat only.
For restrictions that apply to all data services, see the Sun Cluster Release Notes.
Deploy a scalable Sun Cluster HA for Apache Tomcat configuration only if either session replication, or reliable source ip addresses are achieved. Otherwise the behavior of the application becomes unpredictable.
Setting the resource parameter Load_balancing_policy to LB_STICKY is strictly required, if Sun Cluster HA for Apache Tomcat is deployed in a scalable configuration with reliable source ip addresses when no session replication is configured. Otherwise, the behavior of the application becomes unpredictable. In every other scalable configuration the Sticky Load_balancing_policy helps to get the more cache hits out of your caches.
Your data service configuration might not be supported if you do not observe these restrictions.
