[jira] [Created] (AMQ-3610) sharedDeadLetterStrategy is not
discarding the DLQ messages.
sharedDeadLetterStrategy is not discarding the DLQ messages.
------------------------------------------------------------
Key: AMQ-3610
URL: https://issues.apache.org/jira/browse/AMQ-3610
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.5.0
Reporter: Hariharan
Hi,
Am using AMQ 5.5. I would like to disable the option of sending dead letters to ActiveMQ.DLQ destination and completely discard (automatically) the messages that would be sent there otherwise. To do this I had configured the broker as below:
{code:xml}
<amq:destinationPolicy>
<amq:policyMap>
<amq:policyEntries>
<amq:policyEntry topic=">" producerFlowControl="false" >
<amq:deadLetterStrategy>
<amq:sharedDeadLetterStrategy processExpired="false" />
</amq:deadLetterStrategy>
</amq:policyEntry>
<amq:policyEntry queue=">" producerFlowControl="false">
<amq:deadLetterStrategy>
<amq:sharedDeadLetterStrategy processExpired="false" />
</amq:deadLetterStrategy>
</amq:policyEntry>
</amq:policyEntries>
</amq:policyMap>
</amq:destinationPolicy>
{code}
However, I still see that the messages are getting stored in DLQ. Can you please let me know what could be causing this?
Do I need to fix anything in the config?
Thanks
Hari

SuoNayi commented on AMQ-3610:
------------------------------
Property dropTemporaryQueue being set to 'true' means the message should be discarded if the destination of the message is a temporary queue.Similarly Property dropTemporaryTopic means if the destination of the message is a temporary topic the message should be discarded.
Maybe you want to discard other messages such as persistents messages which reside in common queues or topics.
So for more handily,enabling dropAll will discard all DLQ messages.
AFAIK,it's safe to apply this plugin in your production broker and you can take off the old deadLetterStrategy as well.

Hariharan commented on AMQ-3610:
--------------------------------
I tried taking a look at discardingDLQBrokerPlugin.java and found a couple of properties like dropTemporaryQueue and dropTemporaryTopic being set to 'true' by default. Since we use temp queues I would like to know what these properties actually mean and do. Unfortunately there wasn't much doc related to this. Would you know what they do?
Since I will be making this fix in our production broker, I would really like to make sure this plugin would not break anything else which is using temp queues and topics. Sincerely appreciate your help.

With your configuration nonpersistent or expired messages will be discared while persistent messages will be saved.
The plugin will do what you want, it will discard all messages with dropAll being true.
