Configuration for failover

[rakeshxp <ra...@gmail.com>]

Hi,

I have a configuration query regarding use of failovers in activemq. My
current setup is that:
1) I have 2 hosts running activemq with the second host intended to be a
failover
2) On the primary host, I have multiple publishers ( to a single queue ) and
a single consumer reading that queue. 

I am looking to setting up the failover activemq on host2 with the following
requirement:
1) The publishers ( using java client ) should continue to write messages to
the queue on host1 ( and if host1 is down, write it to host2).
2) The consumer ( using java client ) should read the messages in the queue
of host1 and if down, read from host2.
3) When host1 is back online, the consumer should be start reading from
host1 again ( after processing any pending messages on host2).

Could anyone guide me on what is the right configuration ( activemq.xml and
java connect url ) to achieve the same? What is the ideal way to solve the
host failure case?

Thanks in advance!
- Rakesh

Use shared store (either shared file system or jdbc) master slave, have the
producers/consumers use a failover url containing both brokers.

The tricky part is having the consumers revert to host1 after failover
recovery. This requires a reconnect so the consumers should periodically
disconnect. One solution requires the use for a connection pool, having the
pool drop idle connections can help but ideally a pooled connections
lifetime can be restricted. There is an open issue for this, you can add
your vote. see: https://issues.apache.org/activemq/browse/AMQ-2376
