[Help]Qpid in clustering mode

[sonal ojha <s....@gmail.com>]

Hello,

Am very new to Qpid , I wanted to know how could I setup Qpid C++ broker in
clustering mode.

It said to use corosync but then still couldn't find what all setups are
involved.

How can we have them all in multicast mode using a shared database(if qpid
supports one)

Thanks,
Sonal Ojha

There's a newer version of this that is not yet published, and which I 
intend to contribute within a week or so - I basically just need to 
strip out Red Hat stuff from this to make it generic Qpid. I have a 
bunch of docs I intend to move upstream.

I'm happy to supply these docs to anyone who needs them in the meantime. 
I didn't mention them previously because I try not to point people to 
Red Hat docs to answer generic Qpid questions. This problem goes away as 
we move these docs upstream.

I do not know what distribution you are using, but you can compile
qpid on any recent GNU/Linux distribution. See the attached script
which I used today to cleanly compile and install qpid trunk with
clustering module as well.

Then have a look at Red Hat's MRG documentation:
http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_MRG/

You may also play with persistent store module. Have a look at
http://qpidcomponents.org/

  HTH, best regards Ján

There's a page on http://cwiki.apache.org/qpid/ that describes the set-up. 
Unfortunately it seems to be down at the moment so I can't get the exact link. 
When it is back up, look in the FAQ section.

Qpid in clustering mode does use multicast but it does not use a shared 
database. Instead, each member of the cluster keeps its own replica of the 
clusters state, and the replicas are kept synchronized using the corosync CPG 
protocol. New members joining the cluster get a "snapshot" of cluster state from 
an existing member so they too have a complete, synchronized replica of the 
cluster state. Clients can connect to any member of the cluster.
