Subject Failover and updateClusterClients
Date Wed, 23 Jun 2010 05:02:30 GMT

I'm a newbie at this, so please excuse any limitations in my understanding.

We're looking at a load-balanced network of brokers with failover, using a
fixed list of URIs with 4 servers (A - D). We'll be using a common config
across brokers (except broker name). A JWS client will be used.


<networkConnector name="example"
<transportConnector name="openwire"
updateClusterClients="true" />


1) Does it matter if the broker's own IP is included in networkConnector?

2) If broker A goes down, and a client attempts to connect to broker A, is
it 'timeout' that affects how quickly the client will failover to a
different broker?

3) The broker cluster is aware that A has dropped. How is
updateClusterClients represented at the client? Would it be similar to the
client connecting using a random broker from

4) If broker A is restored, will the client be advised of this on the next
successful communication with any broker? If not, when or how?

Thanks for any clarification anyone can give.
