Subject RE: Master/Slave topology in 4.1

Thanks for the reply.

 

In this link http://www.activemq.com/site/masterslave.html, it mentioned
that "in ActiveMQ 4.1 or later you can use a <masterconnector> ...", but
if slave won't replicate master's state, I guess that config element is
not needed, right?

The latter - the slave just grabs and locks the database that the

master is using.
