All,
I am fairly new to AMQ and am facing following issues:-
1) Store percent usage does not decrease. It goes upto 50% and then very
slowly comes down to about 9% and stays there even after producer has
stopped sending messages. It never reaches back to 0%. I found this issue
even after specifying cleanupInterval=30000.
2) Memory percent usage jumps to 60% when 3 producers are sending about 350K
events each - continuously.
3) I have explicitly specified amqPersistenceAdapter . In that case, would I
be getting default values for configuration attributes of AMQ store. Eg:-
cleanupInterval,archiveDataLogs?
I have a single consumer - that is stable and many producers (continuous as
well as random timed)
Short version of activemq.xml looks like:-
Seems xml format did not appear n previous post. This is short version of
activemq config file
<persistenceAdapter>
<amqPersistenceAdapter directory="activemq-data"
maxFileLength="30mb" />
</persistenceAdapter>
<destinationPolicy>
<policyMap>
<policyEntries>
<policyEntry

</storeUsage>
<tempUsage>

</tempUsage>

</systemUsage>
<!-- The transport connectors ActiveMQ will listen to -->
<transportConnectors>
<transportConnector name="openwire" uri="tcp://0.0.0.0:61616"/>
<!-- Uncomment to enable SSL connections

-->
</transportConnectors>
</broker>
I am kind of stuck on above issues for a long duration now and would really
appreciate any help on them. Thanks
