Subject Re: Artemis: Automatic failback does not work

Hi Sebastian,

Good to hear this resolved your problem.  The whole connector/acceptor
concept in Artemis is a little bit confusing.  In short, the acceptor in
the config is a way to configure the broker to allow clients to connect.
It opens a port, configures the protocols etc....

A Connector is essentially information that is passed to the clients (or
other brokers) instructing them how to connect to the broker.  It get's
broadcast to other nodes (providing broadcast is configured),  This allows
cluster nodes to discover each other, they take the connector information
then use it to connect to an acceptor on another node.

In your case, you had the connector/acceptor configured properly on the
master node, so the slave was able to discover and connector to it.  But
when failback happened the master node was unable to connect to the slave
(current live) since the connector information was wrong.

There's a section on transports in the user manual that covers acceptors
and connectors, it's worth a read because the acceptor/connector stuff is
not obvious.
