Subject: [Engine-devel] Ideas = =3D about engine clustering?

Hello, guys:<= di=3D v>
I'm trying to make a jboss clustering environment for engi= =3D ne. But felt the difficuty too.
So I want to know if any one is w= =3D orking on this? I googled it and haven't found anything.

I know there will be lots of things to do for engine migrating to cl= =3D ustering environment. I just want to know what problem need to be solved?
I would like to list the things I think that is needed to do(or so= =3D lve):
1. run jboss in standalone-ha mode or domain mode.
2. add @Clustered annotation to each EJB, I think this will solve the rep= =3D lication problem in cluster, probably lots of details in it.
3. Q= =3D uartzScheduler problem, only one node running a scheduler is enough at a ti= =3D me instead of each node running one.
4. use mod_cluster to handle= =3D load balancing.
5. postgresql clustering.
6. There sho= =3D uld be more, but hope anyone can think about it :D

= =3D
Any ideas?

Depending on yo= =3D ur needs/interests, you might want to have a look at

ovirt-hosted= =3D -engine-setup - allows creating a VM on a host and install an

eng= =3D ine on that VM which will also manage the host

ovirt-hosted-engin= =3D e-ha - allows configuring two such hosts for high availability

of= =3D the engine VM (in the VM level, not application level which is what you di= =3D scussed above).

Both are work-in-progress and are partially usabl= =3D e. Not ready for production, though.
