Qpid C++ broker message persistency
Hi all,
I have started Qpid C++ broker with following configuration in qpidd.conf
file
auth=no
default-queue-limit=0
staging-threshold=1000000
data-dir=/home/lahiru/client/qpidc-0.8/build/persistent
max-session-rate=0
enable-qmf2=yes
worker-threads=4
You can see that I have specified a data-dir for persistence, and after let
the broker run with around 10 queues and I stoped the broker and try to
restart and I do not see any of the queues's or messages which was there
before I shutdown the broker ?
Can someone please advice, If I want to get the behaviour of persistence if
Qpid instance shutdown, how should I configure C++ broker ?
Ex: in the above case when I shutdown the broker if there were 100 message
in Queue A, when I start it again can I have the same state of the broker ?
Thanks in advance
Lahiru

The broker does not implement persistence by itself. A store-plugin is
required to use persistence. You can find one for Linux at:

I have specified a data-dir and also have created durable exchanges and
queues. The durable exchanges and queues are not present after I stop
and start the C++ broker. Please reply back whether your queues and
exchanges are persistent after declaring them as durable and restarting
the broker.

I build the message-store 0.6 with 0.8 qpid build, is this the error, if so
do you have 0.8 message-store to be used ?
I think this won't be the issue, if so how are you going to test the
persistent with 0.8 release ?

Here is a recent posting on the subject (to a different "Adam")
Re: different versions of .NET clients
Chuck Rolke
Mon, 29 Nov 2010 10:29:19 -0800
Adam,
The .NET Binding is hidden away in the /cpp directory.
Here's a way to build it:
1. Fetch the qpid-0.8.tar.gz (57M) to your system. Say, to D:\qpid
2. Unzip, untar (7zip works great) to D:\qpid. You now have
D:\qpid\qpid-0.8\cpp\...
3. Run powershell script
D:\qpid\qpid-0.8\cpp\bindings\qpid\dotnet\configure-windows.ps1
4. This script asks you to identify
a. The directory that holds 32-bit boost. Navigate to it, single click it,
and click OK.
b. The new, out-of-source directory in which to run CMake.
This is the QPID_BUILD_ROOT folder for 32-bit builds.
Select the parent directory for it (the default 'qpid-0.8' is fine)
Press 'Make New Folder'
Type in 'x86' and press OK
c. Run CMake in the folder you created? Press Yes.
d. The questions repeat for a 64-bit build. To skip 64-bit builds, press
Cancel.
For now just press Cancel.
CMake runs to populate your QPID_BUILD_ROOT with generated sources and
project files
5. Navigate to your QPID_BUILD_ROOT D:\qpid\qpid-0.8\x86
6. Build the qpid-cpp.sln solution. For now, just build Debug, Win32.
This is a 'regular cpp build'.
This step produces all the "cpp libraries" that the .NET binding will need.
7. In QPID_BUILD_ROOT execute the procedure
start-devenv-messaging-x86-32bit.bat.
This step launches the .NET Binding solution with QPID_BUILD_ROOT and with
BOOST_ROOT
set appropriately.
8. In the solution, select Configuration Debug, Platform x86. Build the
solution.
After building the .NET Binding solution you will have the binding proper and a
dozen or so
examples like client-server, drain-spout, sender-receiver, and helloworld ready
to run.
This setup allows you to develop 32-bit and 64-bit .NET Binding code without
having to adjust
your environment to find the right version of Boost. The procedure assigns the
*_ROOT values
and then launchs Visual Studio so you always have the correct QPID_BUILD_ROOT
and the
correct Boost in your path.
Thanks Steve and Cliff for clarifying the WCF and DOTNET status.
-Chuck

Re: QPid .net C# client problem
Posted by Cliff Jansen <cl...@gmail.com>.
Hi Adam,
I regret to report that the C# client you are using is not currently
being maintained within Qpid and has been identified as a candidate
for removal.
To paraphrase some recent emails, your best options for Qpid C#
development are as follows:
- The Qpid WCF client
(http://qpid.apache.org/books/trunk/Programming-In-Apache-Qpid/html/ch04.html)
- The .NET Binding for the C++ Messaging Client
(http://qpid.apache.org/books/trunk/Programming-In-Apache-Qpid/html/ch05.html)
Use the former if you have a preference for using the WCF framework or
require distributed transactions managed by MSDTC.
The latter currently enjoys the most active support within Qpid and
gains synergy from the Qpid messaging API work in some of the other
clients.

Hi

Can you give me some advice?
And I have few questions more:
When Im creating sessiom why I must declare expiry in seconds?? Its
timeout for request-response?
Where can I find explanation of patrameters Option??
Is it correct declaration for consumer/message listener or am I doing
something wrong??
private class MessageListener:IMessageListener
