Hello XWikiers,
I've been following the tutorial:
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/DistributedEventCluster…
and the two consoles show me a successful:
grep -i channel mytomcat/logs/tomcat.log

with unchanged udp.xml as extracted with jar -xf from the jgroups jar in WEB-INF.
However the two xwiki's seem to work separately, the data of the other is only fetched
if it has not yet come into cache.
The only suspicious log is, in both consoles:
2012-07-06 08:28:03,208 WARN protocols.UDP - receive
buffer of socket java.net.MulticastSocket@40d3ab8b was set to 25MB, but the OS only
allocated 65.51KB. This might lead to performance problems. Please set your max receive
buffer in the OS correctly (e.g. net.core.rmem_max on Linux)
Is there anything else I need to watch?
The README in the directory of udp.xml was absolutely useless, or at least lead me to no
change... have badly read it?
thanks in advance

After having moved to the tcp-nio protocol stack, and manually adjusting the port numbers
for each instance, I could finally get it to work.
I am still having announces that some ports are connection refused but these are not the
ports I configured but the port +1... is that classical?
Is there an advice for us to use UDP? I would have expected this to be worry free on a
simple desktop when looking at localhost... but well.

Sorry Paul but we are not yet JGroups experts ourself, I mostly used
TCP for tests. You might get more valuable informations from JGroups

Hi,
The tcp-nio protocol is labeled as experimental so there might be surprises with that as
opposed to tcp.
The udp protocol depends on multicast which is likely to be broken in real world networks
as almost nothing depends on it.
I observed the pinging of the next higher port in my testing, here in the default tcp.xml
it is configured
to ping 7800 and 7801 https://github.com/belaban/JGroups/blob/master/conf/tcp.xml#L45

thanks, that had escaped me. I have now moved to TCP.

it is configured

Ok, now I have something like a working jgroups config.
My two hosts are called dev-current-app and dev-next-app, they are configured together
with both tcp.xml configured to look for each other.
I can see the following in my logs after a document save (I save an xwiki object):

nonetheless, the change i made on current-dev only comes to next-dev if I flush cache
which, we agree, is not the solution.
Where else could I look for a bug?

...and a bit later, everything sounds to work very well between next.dev.curriki.org and
current.dev.curriki.org except one thing: obtaining older versions from the Hibernate
store within the notifications interface fails. This happens when a change of document is
made in one node and the listener is running on another node.

Well, there can be another interpretation to the exception I report below: the jgroup even
notifies the new version has occurred (and has arrived) but probably the previous would
not have arrived yet.
Does it make sense?
Do I have another way to tell that the notification has arrived from a remote node of the
cluster?
(we are still using the old notification mechanism but maybe this is a good reason to
upgrade).
thank you much

Well, there can be another interpretation to the
exception I report below: the jgroup even notifies the new version has occurred (and has
arrived) but probably the previous would not have arrived yet.
Does it make sense?
Do I have another way to tell that the notification has arrived from a remote node of the
cluster?
You have the information in the execution context. You can look at how
cache store makes the difference for example. See
https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwi…
(we are still using the old notification mechanism but
maybe this is a good reason to upgrade).
thank you much

Hello XWiki experts,
...and a bit later, everything sounds to work very well between next.dev.curriki.org and
current.dev.curriki.org except one thing: obtaining older versions from the Hibernate
store within the notifications interface fails. This happens when a change of document is
made in one node and the listener is running on another node.
