>
> Key: AMQCPP-491
> URL: https://issues.apache.org/jira/browse/AMQCPP-491
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: Transports
> Affects Versions: 3.7.0
> Environment: Windows 7, VS2010
> Reporter: Daniel Laügt
> Assignee: Timothy Bish
> Priority: Minor
> Fix For: 3.7.1, 3.8.0
>
> Attachments: FailoverTransport.cpp.patch
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Master/Slave configuration with a shared data directory:
> ActiveMQ Configuration (activemq.xml):
> <persistenceAdapter>
> <kahaDB directory="\\host1\kahadb"/>
> </persistenceAdapter>
> URL:
> failover:(tcp://host1:port1,tcp://host2:port2)?randomize=false
> Test case:
> 1) Run ActiveMQ on host2, it becomes the master
> 2) Run ActiveMQ on host1, it becomes the slave
> 3) Run a program that opens an ActiveMQ connection with the url
> 4) Shutdown ActiveMQ on host2
> 5) The ActiveMQ connection is not able to switch to host1.
> Explanation:
> The test case has randomize=false to be able to reproduce the problem
> anytime. If randomize=true, the problem occurs randomly.
> At step 3, ActiveMQ-CPP tries to open first a connection with host1. It fails
> as host1 is the slave. Then it tries to open a connection with host2. This
> time, it succeeds but it forgets to put back the failure hosts (host1) to the
> broker list. At this point, the broker list = (host2).
> At step 5, ActiveMQ-CPP tries to open a connection with the broker list. As
> the broker list = (host2), it will try to open a connection only with host2.
