AW: Session replication embeded tomcat -- update
Dear,
Additionally we tested with jdk 1.5 but still we have the same behaviour.
Packets are in the network, but the embeded tomcat/catalina does not see
them. On windows the session transfer is working fine but non on debian and
suse.
Regards
Robert

Betreff: Session replication embeded tomcat
Dear,
We strugle in replicating tomcat/catalina sessions on two linux server (two
debian etch OR two suse sles10). The surprising thing is that this works
fine for two win xp machines (same config files and same JDK 1.4!).
* On linux we enabled the multicasting checked our network.
* With a network sniffer we see the multicast packets beiing delivered to
all the nodes but ofbiz/tomcat does not pick them.
Thanks
Robert

Thanks,
This is working now! The tomcats "see" each other now.
We now go for the containers.

Robert,
It seems that the mulicast address binding behauviour is different on
windows. The ofbiz-containers.xml cluster example seems also wrong
The replication-mode has a typo. change the line to <property
name="replication-mode" value="pooled"/>
Try to comment out the property name="mcast-bind-addr" and be sure that
multicast is enabled on your ethernet stack. you should also set a multicast
route explictly. Raise the log4j apache log level to INFO and watch out the
log. If the multicast between the machines is working you will got a message
like this:
(Cluster-MembershipReceiver) [ SimpleTcpCluster.java:1107:INFO ] Replication
member
added:org.apache.catalina.cluster.mcast.McastMember[tcp://xxx.xx.xxx.xx:4001
,catalina,xxx.xxx.xxx.xxx,4001,
alive=46772864]
The message means that multicast commnication between different tomcats is
working. For a successful session clustering further steps are needed. For
Example in a Standalone Tomcat env you need an enabled ClusterListener
JvmRouteSessionIDBinderListener and a ClusterSessionListener but I suggest
this is not implemented in the ofbiz yet. Take a look in the
CatalinaContainer Class. The embedded tomcat configuration is done here.
kind regards
Sebastian
