Alfresco Session Clustering on OC4J instance

raaj — Thu, 10 Jan 2008 17:58:06 GMT

As described in the HA doc provided, that client session replication is not supported by alfresco. What does that mean? Does it mean, that client session replication cannot be reached even if the application server(oc4j) generally supports it- eg. oc4j instance cluster supports session replication

All the session data in Alfresco web-client is not fully serializable. We have solved this for 2.2Enterprise - and also should be available in the next 2.9 community release.

As a workaround for v2.1.0 Community, i've tried the http://wiki.alfresco.com/wiki/High_Availability_Configuration_V1.4_to_V2.1#Clustered_Login_Credentials setting Sticky session with login credentials failover but unfortunately I cannot make it work properly.

More configuration details:
- JDK 5.0
- 2 JBoss 4.0.5.GA (not in cluster)
- 1 apache 2.2.4-70.2 as a load balancer
- Open Suse 10.3

Apache2 workers:


# Define list of workers that will be used
# for mapping requests
# The configuration directives are valid
# for the mod_jk version 1.2.18 and later
#
worker.list=loadbalancer,status

# Define Node1
# modify the host as your host IP or DNS name.
worker.nodo1.port=8009
worker.nodo1.host=nodo1
worker.nodo1.type=ajp13
worker.nodo1.lbfactor=1
# worker.nodo1.connection_pool_size=10 (1)

# Define Node2
# modify the host as your host IP or DNS name.
worker.nodo2.port=8009
worker.nodo2.host=nodo2
worker.nodo2.type=ajp13
worker.nodo2.lbfactor=1
# worker.nodo1.connection_pool_size=10 (1)

# Load-balancing behaviour
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=nodo1,nodo2
worker.loadbalancer.sticky_session=1

# Status worker for managing load balancer
worker.status.type=status

and each JBoss has it's own jvmRoute set,
/home/user/tools/jboss-4.0.5.GA/server/nodo2/deploy/jbossweb-tomcat55.sar/server.xml


…
<Engine name="jboss.web" defaultHost="nodo2" jvmRoute="nodo2">
…
<attribute name="UseJK">true</attribute>
‍‍‍‍‍‍

and /home/user/tools/jboss-4.0.5.GA/server/nodo1/deploy/jbossweb-tomcat55.sar/server.xml


…
<Engine name="jboss.web" defaultHost="nodo1" jvmRoute="nodo1">
…
<attribute name="UseJK">true</attribute>
‍‍‍‍‍‍

I think that I'm missing something. Index replication works fine.

Do I have to deploy both jboss instances as a cluster?
Hope somebody could help me, thanks in advance.
Joan.
