The caveauts are here, http://activemq.apache.org/replicated-leveldb-store.html , at the bottom of the page. For the rest, network of brokers and master/slave systems are complementary solutions, aimed at different problems. Generally, a network of brokers provides scalability, while master/slave p

Pure master/slave was removed as not production ready, and since they already found something production-ready that would work with less effort (leveldb). I don't think they will develop the option of having similar functionality with kahadb as well, what's the purpose of maintaining 2 separate sol

Re: Notification of connection down between broker and client?

2014-10-01 Thread Marco Sacchetto

Hi, there are 4 things to check out in your configuration. 1. The JMX configuration should be done from your wrapper file as someone pointed out. Easier to mantain and goes with the documentation, but it's still "optional" as there are several ways to implement it, and as ActiveMQ's documentation l
