<div class="jive-rendered-content"><p>Hi,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I try to set-up JBoss Cache 2 as a Hibernate Second Level Cache on Jboss 5.1.G.A. As a reference I use the document from here: www.jboss.org/jbossclustering/docs/hibernate-jbosscache-guide-3.pdf. </p><p>I run Jboss in a cluster which consists on two Linux machines (RHEL 4 and Ubuntu 10).</p><p>My hibernate.cfg.xml contains these lines:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><code></code></p><p><?xml version='1.0' encoding='UTF-8'?></p><p><!DOCTYPE hibernate-configuration PUBLIC</p><p>          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"</p><p><span>          "</span><a class="jive-link-external-small" href="http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" target="_blank">http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd</a><span>"></span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><hibernate-configuration></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>    <session-factory></p><p>        <property name="connection.username">root</property></p><p>        <property name="connection.password">root</property></p><p>        <property name="connection.url">jdbc:mysql://192.168.223.169:3306/hibtest</property></p><p>        <property name="dialect">org.hibernate.dialect.MySQLDialect</property></p><p>        <property name="connection.driver_class">com.mysql.jdbc.Driver</property></p><p>        <property name="hibernate.show_sql">true</property></p><p>        <property name="hibernate.format_sql">true</property></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>        <property name="hibernate.cache.region.factory_class">org.hibernate.cache.jbc2.MultiplexedJBossCacheRegionFactory</property></p><p>        <property name="hibernate.cache.use_second_level_cache">true</property></p><p>        <property name="hibernate.cache.use_query_cache">true</property></p><p>        <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>        <mapping resource="ro/memiq/training/hibernate/Usr.hbm.xml"></mapping></p><p>        <mapping resource="ro/memiq/training/hibernate/Address.hbm.xml"></mapping></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>    </session-factory></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p></hibernate-configuration></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The cluster starts properly and according to documentation the cache should work properly too. But unfortunately it doesn't. When I read an entity on one node, the I delete it on the other node, then I re-read it on the first node, the entity is still displayed on the first node. The cache on the nodes doesn't synchronize.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I suppose I make a mistake somewhere but I don't see where. If you need more details about the project configuration I will post the here.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Many Thanks,</p><p>Ciprian</p></div>
