Absolutely NO persistence please
Hi!
(I really tried to figure this out by finding other threads and reading
documentation, but unfortunately I did not get further hat way.)
We use ActiveMQ to create concurrent tasks doing some stuff in a parallel
manner for performance reasons. Now, in our case we dont need ANY
persistence whatsoever. Messages by avg. will live for around 3-10 seconds,
and if they take longer they are not needed anymore.
Now, the obvious thing to do is turning persistence off with the
"persistence=false" attribute in the broker. But this does not prevent
ActiveMQ from starting up the Derby Journal thing. Why is that? In all the
other threads seemingly related to this the people either wanted only
journaling or only jdbc persistence, but I dont want any of those!! How can
I archieve that?
(Or is the journal not an optional thing because its used as kind of cache
so the memory does not overflow?)
Thanks very very much!
Cheers,
CC

Amazing!
That did the job. Thanks!
Just so you know that I am not an idiot, please spare one more minute and
look at my configuration (i used this new aproach, embedding non-spring xml
into spring (as suggested by apache.activemq):
>From my point of view, this should actually do exactly what your config
does:
<amq:broker persistent="false"
brokerName="daBroker"
deleteAllMessagesOnStartup="true"
id="broker" >
<amq:managementContext>
<amq:managementContext createConnector="false"/>
</amq:managementContext>
<amq:memoryManager>
<amq:usageManager id="memory-manager" limit="50"/>
</amq:memoryManager>
</amq:broker>
Now why tf did that not work?
Anyway, thanks a lot!!
Cheers,
Werner

Thanks! I will try that!
I think it is the journal, i found this sub directory:
/activemq-data/localhost/journal
and it has 3 .dat files in it..
Thanks again,

I suspect its due to the attribute
deleteAllMessagesOnStartup="true"
since that directive only makes sense (IMHO) if you are doing Persistence/Journaling
Regarding the activemq-data directory ... are you sure its creating journal files and not just the activemq.log file?
That is the default location of the activemq.log file ... which you can change in <ACTIVEMQ_HOME>/conf/log4j.properties

(Please read the other post, it actually works now, BUT: ->
ActiveMQ still creats an activemq-data directory with journal dirs and files
in it, somewhere where I never told it to put it...
Can I turn that off too??
Thanks again!

My needs are similar to yours and I don't see any derby/journal activity.
I'm using ActiveMQ 4.1.1 with the following basic activemq.xml config.
