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
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
