Maximum redlivery count for activeMQ using tMomInput or tMomConnection component

Anonymous — Thu, 15 Feb 2018 22:02:24 GMT

We are trying to connect to Active MQ to Put and Read messages. Is there a way to configure maximum redelivery count to indicate number of retries before a message is backed out to DLQ using tMomInput or tMomConnection component.

As per ActiveMQ documentation, maximum redelivery (retry for a message) is configuration at connection level. I tried setting it at Message level but didn't work. After default 6 retries, the message in DLQ looks like this. I am referring to the circled parameter here... If there's a way to set it using talend Mom components. The other jms parameter in screenshot "maximumRedeliveries = 0" was set manually while storing message to queue and seems like ignored.

I do not know - how to simulate redelivery for test

Yes, sorry the screenshot didn't attach properly. here, "maximumRedeliveries" with value of 0 is what I configured as JMS output property while writing message to queue. However it was still retried 6 times and finally message landed in DLQ with these headers. If you notice the circled parameter in dlq failure cause, it states that was retried 6 times.

do You know - how to force redelivery?

I can see the message being retried max 6 times on failure.

redelivery will occur automatically if there is a failure in the job that consumes message of the queue as long as redelivery count is not 0 and Use Transaction is selected in MomConnection.

I am looking at ways to override the max redelivery count.
