Also, you could consider using a RDBMS as your backing store. It's had less
tuning than KahaDB, and it's not particularly well supported on this
mailing list because I've never used it and I'm not sure if any of the
other active responders have either, but it's more stable than LevelDB and

ActiveMQ allows pluggable storage lockers (

@Tim Thanks for sugegstions
The way I have achieved this is
Step 1:- Making a new queue which take data of existing queue
Step 2 :- Adding consumer for newly created queue

I am using ActiveMQ 5.14.0 and developing my own plugins.

bean properties from activemq.xml on startup.

It would apoear that org.apache.activemq.security.AuthorizationBroker uses
Security context in some way to cache the results of authorization.
This means if I have a dynamic map (i.e. the permissions could change from
one 'send' request to the next, for any destination) the dynamic nature is
lost
I would recommend you guys moving to 1.5.latest though.. it's totally
compatible.

I would suggest checking out something like GlusterFS which created distributed
replicated data. We have used it for high performant applications without
problem. I am not sure how the slave knows how to not start - so this may not
work for you if it is based on file locking.
Thanks

My advice is to simplify your environment, application, and broker
configuration as much as possible while still reproducing the high CPU
utilization. If you can do it with only local resources (e.g. everything
running on a laptop) then that's even better. The simpler and easier it is to

I'd use a composite queue:

Hi Justin,
we've tried by turning off tls. It doesn't change: cpu usage remain very
high.
We've tried also by disabling persistence. It changes a bit: at the
beginning of the connection phase, cpu goes to 50% ...then it increases time
by time til it reaches 100% when there are about 1000 connected
This doesn't directly answer your question, but...
Aside from using the 5.x broker you can use the ActiveMQ Artemis broker [1].
It supports shared-nothing replication for live/backup. See more in the
documentation [2].

You don't need two roles. You just need two "permissions" (i.e.
createNonDurableQueue and consume). A single role can have multiple
permissions.

Hi,
I want to use ActiveMQ's master-slave topology where one broker is master
and other attaches as a slave. But we don't have any shared file system for
it. I know one way to do this is with replicated levelDB but since it is
deprecated, I don't want to go ahead with this. Is there any way we can
