Subject [jira] Updated: (AMQ-2295) Inconsistencies using browseMessages() in JMX on a queue
Date Wed, 17 Jun 2009 19:54:36 GMT


David Schlenk updated AMQ-2295:

I seem to be able to reproduce the problem by connecting and consuming all messages and then
disconnecting, then let a few messages pile up, then run browseMessages and it will return
the proper list at this point. Once more messages come in, however, the browseMessages operation
will continue to get only the list of messages it retrieved during the previous run. This
behavior continues until a consumer connects and begins consuming messages.

> I'm trying to write a utility to monitor our JMS queues using JMX. I'm having a hard
time getting all of the messages currently in queue to show up when I call the browseMessages
operation. It seems to randomly stop keeping track of how many messages are actually in the
queue after a period of time when no consumers are active on the queue. Once a consumer connects
and starts consuming messages then the browse function seems to work OK again. I'm using this
configuration for my persistence:
> <persistenceAdapter>
>             <amqPersistenceAdapter syncOnWrite="false" directory="${activemq.base}/data"
maxFileLength="20 mb"/>
> </persistenceAdapter>
> Messages come in via stomp (<transportConnector name="stomp+ssl" uri="stomp+ssl://localhost:1940)
and are consumed via http (<transportConnector name="ihttp"    uri="http://localhost:61618"/>).
