Hello XWikiers,
I've been following the tutorial:
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/DistributedEventClusterSetup
and the two consoles show me a successful:
grep -i channel mytomcat/logs/tomcat.log
> 2012-07-06 08:28:02,901 INFO jgroups.JChannel - JGroups version:
> 2.12.2.Final
> 2012-07-06 08:28:05,262 [main] INFO .o.r.i.j.JGroupsNetworkAdapter - Channel
> [udp] started
grep -i channel myothertomcat/logs/tomcat.log
> 2012-07-06 08:29:11,857 INFO jgroups.JChannel - JGroups version:
> 2.12.2.Final
> 2012-07-06 08:29:14,251 [main] INFO .o.r.i.j.JGroupsNetworkAdapter - Channel
> [udp] started
also;
GMS: address=atlas-56733, cluster=event, physical
address=fe80:0:0:0:223:dfff:fedf:591d%5:2273
GMS: address=atlas-26026, cluster=event, physical
address=fe80:0:0:0:223:dfff:fedf:591d%5:20950
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
Paul
