PropertyDescription

configurationName

Specifies a cache instance or template defined in $RHDG_HOME/server/conf/infinispan.xml. Your application then creates a cache instance that uses the configuration from the named cache.

persistenceStrategy

Defines how sessions map to entries in the cache.

COARSE stores all attributes of a session in a single cache entry. This is the default.

FINE stores session attributes in separate cache entries.

maxActiveSessions

Defines the maximum number of sessions to store in the cache. The default is no maximum (limitless).

To configure Hot Rod clients, specify properties without the infinispan.client.hotrod. prefix. For more information, see the Hot Rod Client Configuration API.

You can also specify common attributes for the Session Manager. Refer to the appropriate version of the Apache Tomcat documentation as follows:
