In our production system we switched from the one directional mirroring to dual
mirroring as supported by Artemis 2.20+. At the same time we renamed the mirror
to have distinct names on both datacenters (BOS and SJE), previously the
mirrors were simply called mirror on both sides.
We did that

I am using ArtemisMQ 2.20.0; these servers were running 2.17.0 until a few
weeks ago.
Hello,
We’re using Artemis 2.20. We had a misbehaving application that had been
opening consumers without closing them which I recently addressed. The fix was
deployed today and since then I have been seeing a lot of the following error

Hello,
A problem I've hit a couple times is that we've forgotten to deploy
our updated addresses before deploying the applications that use them.
This ends up succeeding because auto-create is enabled, but the
addresses and queues are configured with auto-delete: true and
configuration-managed:
I was purging ExpiryQueues and I noticed the following warning in our Artemis

reproduce).

Thanks,
I am a little concerned about how this reflects production readiness given
there are no schema changes mentioned in the upgrade notes and it looks to me
like it’s backwards incompatible so it couldn’t be done live before the upgrade?

We have an Artemis MQ instance in our QA environment that we are using to
evaluate JDBC persistence.
It was running with Artemis 2.20, and we recently updated to 2.22. Since then
the instance has failed to start with the following error:

Understood thank you. We (the company I work for) are definitely getting more
value out of the product than we are contributing, so that point is taken. The
JDBC replication route was recommended by a consultant from Savoir as more
established/reliable than mirroring when delivery guarantees

website.
Out of curiosity, how is your MySQL replication configured? Are you using
the default asynchronous, semisynchronous, or fully synchronous NDB cluster?

It seems the documentation for the artemis cli tool is particularly out of date.
The Data Tools page references the following subcommands of artemis data:
print

compact
recover
But only print and recover appear to exist.
The Activation Tools documentation lists:

Are there any thoughts on how to achieve fair queuing with Artemis MQ.
We have a limited resource (the consumer) and many of our customers are
producing messages for it. We do not want a customer producing a lot of
messages from blocking a customer that only sends a few (basically the
on the client side.
I’m not sure also If you need a rate limiter or something like that also ?

I fixed some critical analyzer issues. You should upgrade.
Or just turn off the critical analyzer.

a Mirror is a mirror.. .if you send to that mirror, the send will then
update the mirror back.. that's a bit of a mess! Make it simple!

We are running artemis multiple artemis clusters between hot and cold
datacenters in a dual mirroring setup, so:
A mirrors with A’
B mirrors with B’
We also have core bridges between A and B so:
A.forwardBfoo goes to B.foo
A’.forwardBfoo goes to B’.foo (by virtue of symmetric configuration)
I traced this code quite recently because we needed to switch to using it for
one of our clients and also would have preferred specifying it on the consumer.
ClientSession in the core API exposes the windowSize as a parameter for
creating consumers, but the JMS shim ActiveMQSession does not.

We are planning our production upgrade from 2.20 to 2.25. These upgrades
involve a loss of service in the window between stopping the live and when the
backup instance becomes ready to process messages.
I was wondering if the mirror protocol is expected to be compatible between
those versions.

We have a queue in our production system (on Artemis 2.27.1) that ended up
being used before it was defined in our broker.xml.
This meant that the address has the “Auto created: true” attribute, and the
queue under it ended up with “Auto delete: true” and “Configuration managed:
false”
We run
We are performing some extended maintenance in our cold datacenter and
our artemis mirrors are backing up (currently around 2G of messages.)
What is the recommendation to "safely" disable the capture of new
events for mirroring / flush the mirrors queues.
