Hi

I'm not expert but I could share my experience and may be from
activemq team could make a correction if I do a mistake.

You need to configure in this way:

<networkConnector
uri=3D"static:(tcp://A:outputport,tcp://B:transportport)">
failover=3D"true"/>

I mean, the first data is the output port of the broker you are
configuring and the others are server to wich you one to connect and
its transport ports (because brokers receive data from transport)

You must list in client al servers you want to connect with its transport p=
orts.

In this way, client will try to connect randomly (as far as I
remember) but you can force to assure to connect in the order you
wrtie them.

AFAIK, two brokers in different directories or at least with different
journals. Also, if you are using persistence in DD, they should use
different DB's.


Hope this helps and sorry if I did a mistake with my explanation
