New features

Clustering enhancements

• New module cluster daemon permitting to control remotely the JOnAS instances through JMX. See in the JOnAS documentation the cluster daemon chapter.

• JOnAS commands enhancements for supporting the remote deploy/start/.... The jonas admin command supports the 'target' option for specifying the remote node in the domain. The command has to be launched on the master node.

• Enhanced state management for servers (support an enriched state diagram for domain and cluster members). Also support cluster state management based on the members' state.

• Dynamic update of the cluster view at the client side with the CMI protocol. In the previous version, the cluster view at the client side was not updated dynamically when a new node appears in the cluster. The new version relies on the HA interceptor for exchanging information during the remote method calls and thus for maintaining an up to date cluster state at the client side.

• Distributed view of the CMI registry in the jonasAdmin console. The 'Registry' tab of the jonasAdmin console for a node configured with the cmi protocol provides for each known EJB the list of the servers where it is deployed.

• EJB replication framework enhancements : the SFSB replication framework is enhanced in this version for supporting the EB calls and for ensuring the transaction and global consistency. When the cluster is configured with a DB supporting the tx isolation (PostGreSQL, Oracle), the mechanism ensures that the tx are executed at most once even during a fail-over. See the clustering wiki for futher information. The sampleCluster2 example is updated for illustrating the new capabilities. See the wiki here https://wiki.objectweb.org/jonas/Wiki.jsp?page=HorizontalReplication for further information.

• Cluster monitoring in the jonasAdmin console (master node)

• Allow starting and stopping servers in domain (may be or not cluster members) if they have associated a cluster daemon.
• Automatic discovery of the physical clusters through a mechanism polling some specific MBeans.
• The physical clusters are configured for ensuring HA or scalability. The identified clusters are detailed in the clustering wiki here https://wiki.objectweb.org/jonas/Wiki.jsp?page=ClusterMonitoring :

• jkCluster : cluster built through the mod_jk configuration for ensuring LB at the web level
• tomcatCluster : cluster built through the tomcat configuration for ensuring HA at the web level
• cmiCluster : cluster built through the CMI configuration for ensuring LB/HA at the jndi and ejb level
• ejbHaCluster : cluster built through the HA service for ensuring HA at the EJB level
• The logical clusters (logicalCluster) are configured for management purposes in the domain.xml file or through the jonasAdmin console.
• Consult monitoring information about the cluster members (status, statistics) through a new tree reflecting the cluster topologies -> need to be completed.

• Cluster deployment through FDF (Fractal Deployment Framework). This new tool may be used for ensuring both the deployment of the middleware (JONAS_ROOT, JONAS_BASE) over a cluster and the starting of the bootstrap such as the cluster daemon. A description is available in the JOnAS documentation in the Advanced topic part and in the clustering wiki here https://wiki.objectweb.org/jonas/Wiki.jsp?page=MiddlewareDeployment.

• newjc enhancements
• integration of the jcl script for controlling the cluster
• 3 new instances are configured and launched with the cluster members (jb1, ..., jb4)
• a cluster daemon that is used for controlling the JOnAS's cluster nodes remotely through a JMX interface (start/stop)

• a JOnAS instance called db that ships a HSQL db and that is dedicated to the db tier. Thus the fail-over tests can be done regardless the db level. In the previous version, the feature was supported by the third node. If you configure a link to an Oracle db, the 'db' instance is useless. In the current version, the global start (jcl4sc2.sh start) launches all the instances whatever you've configured but it shouldn't cause a problem in your test
• a JOnAS instance called master dedicated to the domain/cluster management. In the previous version the feature was supported by the 1st cluster node.

• JGroups 2.2.9.3 : a new version of the group communication protocol fixing a few bugs. See here http://sourceforge.net/project/shownotes.php?release_id=430967&group_id=6081 for the release notes

• New non regression tests for the basic clustering features in the JOnAS's tests suite. See the wiki here https://wiki.objectweb.org/jonas/Wiki.jsp?page=JOnASClusteringUnitTests for a brief description.

• Warnings

• Documentation about tools for JOnAS remote control will be provided in the next version and will be available on the JOnAS wiki as soon as possible.
• Cluster monitoring in JonasAdmin has to be completed (pages under construction). This feature is young and need to be tested more intensively (bug reports/suggestions are welcomed).

JORAM enhancements

• New JORAM version : 4.3.20 supporting the JORAM HA mode through the resource adapter. A new JMS clustering how to document is provided in the JOnAS documentation. See the how to part.

• The joramplatform node of the jonasAdmin console supports 2 new buttons :
• dynamic reload of the joramAdmin.xml
• export JORAM repository content to the joramAdminExport.xml (topic, queue objects)

Misc.

• TMF (Thread Management Framework) : this new tool aims to publish some statistics about the thread activity in the JOnAS JVM. By default, this mechanism is disabled. The documentation is available in the JOnAS doc (see Advanced topic) and on the wiki here. https://wiki.objectweb.org/jonas/Wiki.jsp?page=JOnAS_TMF
