But felt the difficuty too.</div><div>So I want to know if any one is working on this? I googled it and haven't found anything.</div><div><br></div><div>I know there will be lots of things to do for engine migrating to clustering environment. I just want to know what problem need to be solved?</div><div>I would like to list the things I think that is needed to do(or solve):</div><div>1. run jboss in standalone-ha mode or domain mode.</div><div>2. add @Clustered annotation to each EJB, I think this will solve the replication problem in cluster, probably lots of details in it.</div><div>3. QuartzScheduler problem, only one node running a scheduler is enough at a time instead of each node running one.</div><div>4. use mod_cluster to handle load balancing.</div><div>5. postgresql clustering.</div><div>6. There should be more, but hope anyone can think about it :D<br></div><div><br></div><div>Any ideas?</div></div></blockquote><div><br></div><div>Depending on your needs/interests, you might want to have a look at</div><div>ovirt-hosted-engine-setup - allows creating a VM on a host and install an</div><div>engine on that VM which will also manage the host</div><div>ovirt-hosted-engine-ha - allows configuring two such hosts for high availability</div><div>of the engine VM (in the VM level, not application level which is what you discussed above).</div><div>Both are work-in-progress and are partially usable. Not ready for production, though.</div><div><br></div><div>Regards,</div><div>-- <br></div><div><span name="x"></span>Didi<span name="x"></span><br></div><div><br></div></div></body></html>
