No. I want to use the same configuration as yours: Datacenter1 (Master A /
Slave B) <=> Datacenter2(Master B / Slave A)
But if you shutdown master which loose connection to slave that means some
messages which is contained by current master won't relocated to another
master in time.
I think better solution is full replication of master's sate at the moment of
attaching slave to master. Also slave musn't shutdown on loosing connection to
master, becasue it's possible network problem. Slave must retry to reconnect to
master in current of hour, for example, and then shutdown.
It's too hard to our operations team restart ActiveMQ server each time when
network is down.
Unfortunely, network problems happen very often. Sometimes electricity is down
in all datacenter...
I think master must keep working when slave is disconnected. I derrived slave
BrokerService and added reconnection logic. Problem for me is master state is
not fully replicated on attaching slave.
I think, shutdowning master is bad solution.
Crashing of both hardrives of both severs is less probable

>
> It is related to AMQ-596 in terms that it is desirable that master and slave
> are in synch and when both are down, failover can direct the job to other
> pair of master/slave. So pure master/slave can be used for replication while
> a network of pair (master/slave) will provide a HA service.
