Gary Tully commented on AMQ-6772:
---------------------------------
it won't work at all via the runtimeConfigurationPlugin, you will need a
wildcard in the default config to enable it for every queue, this then is
applied for queues created at runtime in the normal way.
if you want to selectively disable, you will need to restart. It is a
performance tweak to disable it, that may not be relevant in your environment.
> runtimeConfigurationPlugin - prioritizedMessages property update at Runtime

> Key: AMQ-6772
> URL: https://issues.apache.org/jira/browse/AMQ-6772
> Project: ActiveMQ
> Issue Type: Bug
> Components: runtime configuration plugin
> Affects Versions: 5.14.5
> Environment: Unix
> Reporter: Anil P.
>
> I have configured the 'runtimeConfigurationPlugin' and started the Active MQ.
> Then added the below in policyEntries:
> <policyEntry queue="test.configuration.dynamic.update"
> prioritizedMessages="true" useCache="false" expireMessagesPeriod="0" />
> After saving the config file, I am able to see that the console log got
> updated saying that config changes are detected and loaded.
> When tested, however, Message Priority is not being enforced as expected on
> the queue.
> I checked in JConsole, I am not able to update this particular property there
> either.
> If I restart with the policy configured, the property is getting applied and
> it is working as expected. It is only not happening if I try to have it
> updated at run-time.
> Tim dug into the code, and discovered that the
> PolicyEntry.update() and PolicyEntry.baseUpdate() methods (
> https://git-wip-us.apache.org/repos/asf?p=activemq.git;a=blob;f=activemq-broker/src/main/java/org/apache/activemq/broker/region/policy/PolicyEntry.java;h=5b7ff0e184b9e6b4be6cf61ebcacc0a845bb1a6c;hb=HEAD)
> don't attempt to set any of the three properties being passed in.
> Please fix this so that those attributes will be set when the policy entry is
> reloaded.
