activemq broker

In the real enterprise, the application of message communication has been very hot, and plays a special role in the enterprise application of the Java EE, so it is very necessary to study it. On the basic concept of JMS (i) –JMS, we introduced the canonical JMS of message communication, and this blog post introduces an open source JMS implementation--ACTIVEMQ. ACTIVEMQ is an easy-to-use message middleware

Abstract: ActiveMQ optimized thread Optimization Address: http://fusesource.com/docs/broker/5.4/tuning/PersTuning-Threading.html Optimized dispatch: In Broker configuration, you can set OptimizedDispatchIs TrueTo reduce the demand for Tread. In this way, the Broker will not use a dedicated thread for each targ

In the following three scenarios, the ACTIVEMQ message is sent back to the client/consumer: 1. Use a transaction session, and call the rollback () method; 2. A transaction session, a commit was called before closing; 3. The Client_acknowledge signature mode is used in the session, and the Session.recover () method is called. The broker uses the Brokerinfo command package to establish a connection to the c
