Hi,
I want to know if the following is JMS Failover or MQ Failover.
I have two channels to response message to JMS: Primary and Secondary.
So I think I need to make failover programtically if primary queue is failed.
So it is JMS Failover or MQ Failover?
is there any reference programming guide or other concepts link for failover??
Thanks in advance. |

Well there is no difference really if both CF's are from the same provider, yes? For MQ failover I would suggest either a Multi Instance qmgr or a channel table. (less programming)...
Have fun

Hi,
I think to do failover, i need to check only queue session after connection with CF.
QueueConnectionFactory jmsConnectionFactory = (QueueConnectionFactory) ic.lookup(pr_factoryName);
Queue queue = (Queue)ic.lookup(pr_queueName);
QueueConnection connection = jmsConnectionFactory.createQueueConnection();
jmsSession = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
if (jmsSession == null){
...
...
...
}
is it the correct way to make failover?? if jmsSession(QueueSession) is null, it means the queue connection is failed. So i'll manage to connect secondary queue??? is it??
thanks |
