ActiveMQ failover with temporary queues on a network of brokers?

阅读更多关于 ActiveMQ failover with temporary queues on a network of brokers?

问题 We have a network of four brokers, 2 "front-end" and 2 "back-end" (I'll refer to them as FB1 FB2 BB1 BB2). They are networked in a square like so: FB1 .... FB2 . . . . . . BB1 .... BB2 The network connections are set to exclude specific queues but otherwise allow forwarding of all other queues and topics. The network connectors have failover defined between front-end and back-end so if, for example, BB1 went down then FB1 should failover and establish a new network connection to BB2. Clients

DMLC message consumption and acknowledgement

阅读更多关于 DMLC message consumption and acknowledgement

Since the listener is still executing, how will the consumption and acknowledgement works for subsequent messages?

But is there a way I can run activemq and clean install both with 1 command on the same console? Basically I wish that when I do mvn clean
