Ivan commented on GERONIMO-4955:
--------------------------------
Hi, Lu Jiang:
Just try it with Geronimo 2.2, the unicast does work from my side. But some
configurations need to be updated
1. For Geronimo 2.2, so far, I think that you should only set cluster on the
web application level, which means that all the configurations are in the
deployement plans.
2. For some API changes in Tomcat 6.0.20, setManagerClassName method is
deprecated, so you need to define clustermanager gbean in the plan file, not
use the managerclassname attribute in the CatalinaClusterGBean defintion.

> Below is a senario:
> 1.Install geronimo 2.2 on two machines,namely
> 9.186.10.60(NODE02),9.186.10.89(NODE03).
> 2.Configure Apache http server.
> (1)add mod_jk.so to ApacheHttpServer_HOME/modules.
> (2)add or modify workers.properties under ApacheHttpServer_HOME/conf like
> worker.list=loadbalancer,status
> worker.maintain=60
> worker.NODE02.port=8009
> worker.NODE02.host=9.186.10.60
> worker.NODE02.type=ajp13
> worker.NODE02.lbfactor=1
> worker.NODE03.port=8009
> worker.NODE03.host=9.186.10.89
> worker.NODE03.type=ajp13
> worker.NODE03.lbfactor=1
> worker.loadbalancer.type=lb
> worker.loadbalancer.balance_workers=NODE02,NODE03
> worker.loadbalancer.sticky_session=1
> worker.status.type=status
> (3)add information below to ApacheHttpServer_HOME/conf/
> LoadModule jk_module modules/mod_jk.so
> JkWorkersFile conf/workers.properties
> JkLogFile logs/mod_jk.log
> JkLogLevel debug
> JkMount /* loadbalancer
> 3.
> For NODE02:
> (1)Modify GERONIMO_HOME/var/config/config-substitutions.properties
> ClusterNodeName=NODE02
> (2)Modify GERONIMO_HOME/var/catalina/server.xml.
> <Engine name="Catalina" defaultHost="${ServerHostname}" jvmRoute="NODE02" >
>
> For NODE03:
> (1)Modify GERONIMO_HOME/var/config/config-substitutions.properties
> ClusterNodeName=NODE03
> (2)Modify GERONIMO_HOME/var/config/config.xml.
> <Engine name="Catalina" defaultHost="${ServerHostname}" jvmRoute="NODE03" >

> 3.
> I tried two ways to enable unicast clustering..One is to enable it in
> config.xml and the other is to enable it in the deploy plan.
> (Deploy the ream.xml first cause we have security realm configuration in the
> application )
> The first way:(enable it in config.xml)
> On the two server,separately add GBean information under<module
> name="org.apache.geronimo.configs/tomcat6/2.2-SNAPSHOT/car">
> Refer to the attachment:node02ExcerptFromConfig.xml and
> node03ExcertFromConfig.xml
> Then deploy the application servlet-examples-cluster-server2.war using Simple
> simple-servlet-examples-cluster-plan2.xml as a deploy plan.
> deploy the application servlet-examples-cluster-server3.war using Simple
> simple-servlet-examples-cluster-plan3.xml as a deploy plan.
> The second way:(enable it in deploy plan)
> Without modification to config.xml,deploy the application directly.
> deploy the application servlet-examples-cluster-server2.war using
> servlet-examples-cluster-plan2.xml as a deploy plan.
> deploy the application servlet-examples-cluster-server3.war using
> servlet-examples-cluster-plan3.xml as a deploy plan.
> Expected:
> Session will be replicated .When node 02 fails,the node 03 will be the back
> up.and vice versa.
> But currently both way don't work, when node2 fails ,session is not
> replicated to node03
