[jboss-jira] [JBoss JIRA] Updated: (JBAS-5536) UnifiedInvokerHAProxy replicants are not updated when other nodes undeploy beans

     [ http://jira.jboss.com/jira/browse/JBAS-5536?page=all ]

Galder Zamarreno updated JBAS-5536:
-----------------------------------

    Workaround Description: 
The obvious workaround is to use JRMP invokers instead of Unified invokers while this 
gets sorted as JRMP invoker proxy ha does implement InvokerProxyHA. To do that, take 
your EJB and add the following to the beans jboss.xml so that it uses JRMP invoker instead 
of Unified:

<jboss>

    <enterprise-beans>

       <session>
          <ejb-name>Boo</ejb-name>
          <jndi-name>ejb/BooEjb</jndi-name>
          <configuration-name>JRMP Clustered Stateless SessionBean</configuration-name>
          <clustered>true</clustered>
       </session>

    </enterprise-beans>
    
    <container-configurations>
          
      <container-configuration extends="Clustered Stateless SessionBean">
         <container-name>JRMP Clustered Stateless SessionBean</container-name>
         <invoker-proxy-binding-name>clustered-stateless-rmi-invoker</invoker-proxy-binding-name>
      </container-configuration>      
     
    </container-configurations>    

</jboss>

>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: Clustering, Remoting
>    Affects Versions: JBossAS-5.0.0.Beta4, JBossAS-4.2.2.GA

> We have a big regression at out hands. When we moved to unified 
> invokers, we lost the ability for home/bean proxies to be updated 
> when another node undeploys a bean. Why? 
> ProxyFactoryHA.replicantsChanged looks something like this 
> (the trace logs were added by me during debugging):
>    public synchronized void replicantsChanged (String key, 
>                                                List newReplicants, 
>                                                int newReplicantsViewId)
>    {
>       try
>       {
>          if (homeInvoker instanceof InvokerProxyHA)
>          {
>             if (log.isTraceEnabled())
>             {
>                log.trace("Updating home proxy with new replicants " + target.getReplicants() + ", view=" + target.getCurrentViewId ());
>             }
>             ((InvokerProxyHA)homeInvoker).updateClusterInfo (target.getReplicants(), target.getCurrentViewId ());
>          }
>          if (beanInvoker instanceof InvokerProxyHA)
>          {
>             if (log.isTraceEnabled())
>             {
>                log.trace("Updating bean proxy with new replicants " + target.getReplicants() + ", view=" + target.getCurrentViewId ());
>             }
>             ((InvokerProxyHA)beanInvoker).updateClusterInfo (target.getReplicants(), target.getCurrentViewId ());
>          }
>          log.debug ("Rebinding in JNDI... " + key);
>          rebindHomeProxy ();
>       }
>       catch (Exception none)
>       {
>          log.debug (none);
>       }
>    }
> UnifiedInvokerHAProxy *does not* implement InvokerProxyHA, so unified invoker ha 
> proxies will never have their replicants updated.
