Subject [jira] [Commented] (ARTEMIS-933) Artemis cluster with ha-policy replication is not working
Date Wed, 01 Mar 2017 21:29:46 GMT


Justin Bertram commented on ARTEMIS-933:

After slighly modifying the attached configurations I tested this scenario by running all
three instances on my box with both 1.5.3 and the current master branch.  As soon as I stopped
the live broker the first slave took over and became live.  Then when I stopped the now-live-slave
the second slave became live.

There are 4 replicated HA examples shipped with Artemis.  Do any of those work for you?

We see that the master node is actively accepting connections:

not become active itself:

> {code}
> When I do a kill -9 on the PID of the master java process, it does not even report that
the master has gone away.
> I also tested this in 1.5.1, with the same results.
> My expectation is that if the master dies, one of the slaves becomes active.
> Attached you will find the broker.xml of all 3 nodes.
