Atlast , I have got the two jboss portal clustered nodes up and running with the below
configuration changes, including the changes specified in the JBoss portal 2.7.2
documentation.
1. In Portal/Portlet/Instance/User hibernate.cfg.xml adde the following properties
<property
name="hibernate.cache.provider_class">org.jboss.hibernate.jbc.cacheprovider.JmxBoundTreeCacheProvider</property>
<property
name="hibernate.treecache.mbean.object_name">portal:service=TreeCache,type=hibernate</property>
Shimilarly make the changes to portal, portlet and user modules.
2. Download the below jar and add the jar to jboss-portal-2.7.2/server/all/lib
hibernate-jbc-cacheprovider-1.0.1.GA.jar
See if there is any other version of the jar, replace it with the above jar.
3. In instance, user, portal, portlet modules, in domain.hbm.xml, replace the word
“read-write” in <cache-usage> tag with the work “transactional”.
4. In instance, user, portal, portlet modules, in hibernate.cfg.xml, make the secondary
level cache to true.
Below is the tag for reference:
<property name="cache.use_second_level_cache">true</property>
5. in jboss-service.xml for ObjectDeploymentFactory there is a attribute which is set to
true by default
<!-- Set to false in clustered mode, otherwise set to true -->
<attribute name="RegistrationControlledByService">true</attribute>
Set it false.
*** Now even the servers are up with TreeCache, if I update the data in one node, then the
data is not replicating in the other node simultaneously. Please let me know, if there is
any other configuration change that needs to be done...!
