Federation & Push Routes & Exclusive access to queue
Hi Guys,
I have a start topology where there is a Qpid 0.14 on center and many Qpid
0.18 are around. I want to configure push routes which go from center to
around. The problem is if more than one around broker become active, on the
center broker I have a regular exception:
error Execution exception: resource-locked: Cannot grant exclusive access
to queue bridge_queue_1_3cce3cda-d396-4ff6-9ee8-853b4d09d8a1
(qpid/broker/SessionAdapter.cpp:332)
I noticed that there is just one queue (i.e. bridge_queue_1_xxxxxxx ) for
all of the push routes and apparently server needs to grant exclusive
access to it for every route.
BEST,
Afshin Afzali

Hi, Afshin. I can hopefully answer your packaging question.
Regarding CentOS, we're limited as to what we can release on that distro
by what is in base RHEL, on which CentOS is based. We can release
packages via the EPEL [1] repositories, but we can't release anything
there if it exists in base RHEL/CentOS.
So, for RHEL6 and CentOS 6, we were previously unable to push updates
since Qpid 0.14 was already packages in base RHEL. However, that has
changed and we are currently looking into how we can push updates into
EPEL for RHEL6, which CentOS can use.
For RHEL7 and CentOS 7 we do have Qpid 0.28 available current [2].
On Debian I'm currently looking for sponsorship to update the Qpid
packages available. The previous maintainer retired from Debian a couple
of years ago and the package languished until recently. I have 0.28
packages for Debian [3] but it's a slow process for package adoption in
Debian (it took roughly 3 months or so for me to get qpid-proton adopted).
HTH.

Hi Gordon,
Thanks for your info!
Actually I did it as you said by creating a queue for each route :)
And I don't know why the guys don't update distribution packages on
repositories (I mean CentOS / Ubuntu)?
Best and Appreciate
Afshin

Yes, that was https://issues.apache.org/jira/browse/QPID-3773, which was
fixed for later versions. Is there any way you can upgrade?
If not you could instead try explicitly create a queue for each push
route, bind it to the exchange and then do a queue sourced push route.
