Key: AMQCPP-653
URL: https://issues.apache.org/jira/browse/AMQCPP-653
Project: ActiveMQ C++ Client
Issue Type: Bug
Environment: OS: SLES 11 SP3
ActiveMQ C++ Library 3.9.3
ActiveMQ sever 5.15.9
Reporter: Srikrishna Erra
Assignee: Timothy A. Bish
We have a C++ Application using ActiveMQ C++ 3.9.3 Library to interact ActiveMQ
Server.
We are testing failover and failback functionality with Master and Slave
ActiveMQ Borkers.
#1. Starting with, Master Broker Up and Slave Borker Down, we could
scuccessfully establish connection and send/receive messages.
#2. Tested Failover (switch to Slave Broker) with Master Broker Down and Slave
Broker Up. We could successully establish connection and send/revceive messages
#3. Tested Failback (switch back to Master Broker) with Master Broker Up and
MakingSlave Broker Down again. We could successully establish connection and
send/revceive messages
#4. Our C++ application being running, Master Broker being Up and Slave being
down, the setup was intact for few days with no activity.
After few days, we have just stoped and started our application with still
Master Broker being Up and Slave being down. Our application's stop and start
was clean.
But we just got Expception now. Here are the Details.
==========================================================
Process ID: 14606
Threads ID: 14612 ==> Connecting with Master Broker which is Up. So, no
issues.
14613 ==> Connecting with Slave Broker which is Down. Got
an Exception.
