    HAModClusterServiceMBean removed in mod_cluster 1.2.6.Final and what does it mean?

      Hi,

       

           I saw HAModClusterServiceMBean.java is removed since 1.2.6.Final: https://github.com/modcluster/mod_cluster/commit/c50037d69b18305ec4143654758596d51555d1cd

       

           Does that mean the "Clustered mode" will be removed from now on?

          Paul has helped to answer this question:

           

          Q:

          In "standalone/deployments/mod_cluster.sar/META-INF/mod_cluster-jboss-beans.xml" it has:

          <annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.web:service=ModCluster",exposedInterface=org.jboss.modcluster.ha.HAModClusterServiceMBean.class)</annotation>

          Is the "org.jboss.modcluster.ha.HAModClusterServiceMBean.class" used in AS7?

          A:

           

          No - it is not. The jboss-ha-server module on which it depends does not

          exist in AS7.

           

          Q:

           

          I saw this "org.jboss.modcluster.ha.HAModClusterServiceMBean.java" has been removed since 1.2.6.Final, does that mean the 'clustered mode' is already deprecated?

           

          A:

          Correct. We removed this for a couple of reasons.

          * It depends on code from AS5/6 that was deprecated in AS7.

          * It added a lot of complexity without much added value

          * The biggest benefit, i.e. the execution of manageement operations to

          an entire load balancing group, can be implemented via AS7 management

          operations on the domain controller.

           

           

          Q:

           

          Does mod_cluster talk with every node in AS7 cluster or it just communicate with the domain controller?

           

           

           

          A: Each node communicates with the load balancer.

           

          Q:

          Are their any differences when mod_cluster is working with standalone mode and domain mode?

           

          A: None
