23.4.3. The HASessionStateService configuration
The
HASessionStateService
bean is defined in the <JBOSS_HOME>/server/<PROFILE>/deploy/cluster/ha-legacy-jboss-beans.xml
file.
<bean name="HASessionStateService" class="org.jboss.ha.hasessionstate.server.HASessionStateService"> <annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX (name="jboss:service=HASessionState", exposedInterface=org.jboss.ha.hasessionstate.server. HASessionStateServiceMBean.class, registerDirectly=true)</annotation> <!-- Partition used for group RPCs --> <property name="HAPartition"><inject bean="HAPartition"/></property> <!-- JNDI name under which the service is bound --> <property name="jndiName">/HASessionState/Default</property> <!-- Max delay before cleaning unreclaimed state. Defaults to 30*60*1000 => 30 minutes --> <property name="beanCleaningDelay">0</property> </bean>
The configuration attributes in the
HASessionStateService
bean are listed below.
- HAPartition is a required attribute to inject the HAPartition service that HA-JNDI uses for intra-cluster communication.
- jndiName is an optional attribute to specify the JNDI name under which this
HASessionStateService
bean is bound. The default value is/HAPartition/Default
. - beanCleaningDelay is an optional attribute to specify the number of milliseconds after which the
HASessionStateService
can clean a state that has not been modified. If a node, owning a bean, crashes, its brother node will take ownership of this bean. Nevertheless, the container cache of the brother node will not know about it (because it has never seen it before) and will never delete according to the cleaning settings of the bean. That is why theHASessionStateService
needs to do this cleanup sometimes. The default value is30*60*1000
milliseconds (i.e., 30 minutes).
