Stickiness and load balancing does not work at the same time

[burakbayramli]

Hello, based on the info from Wiki and some other resources, I was able to setup Apache --> mod_jk --> JBoss 4.0.1 using single node. However I had problems with clustering. It seems that, I can only use sticky behavior, or load balancing, not both at the same time.

When I changed my workers.properties file to:

worker.node2.port=8109
worker.node2.host=localhost
worker.node2.type=ajp13
worker.node2.lbfactor=100
worker.node2.local_worker=1

worker.node1.port=8209
worker.node1.host=localhost
worker.node1.type=ajp13
worker.node1.lbfactor=100
worker.node1.local_worker=1

worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=node2,node1
worker.loadbalancer.sticky_session=1
worker.loadbalancer.local_worker_only=1

JMeter load tests keep going to the same server. One node is not utilized at all, it is as if the second node (whichever node is listed last in the worker.loadbalancer.balanced_worker list) does not exist.

If I comment out worker.node2.local_worker line for both nodes, then I get load balancing, but no session stickiness.

I have checked the jmvRoute option in server.xml file, it looks OK.

I am using Apache 1.3, JDK 1.4.2 and JBoss 4.0.1 running on SuSe 8.

I've read JBossClustering.pdf document (which is for JBoss 3).

Any help would be appreciated.

Thanks,

Which you either didn't read or decided to not to use, because
your configuration is not the same as that shown there.
http://wiki.jboss.org/wiki/Wiki.jsp?page=UsingMod_jk1.2WithJBoss

Anyway, I changed the footnote to step #5 to make it more clear
and I added a short summary at the top.
Print it out and tick each step when you've done it.

Thanks, this worked. I had been using Apache 1.3, so I was taking some parts of Wiki and not others.

To get things running, I did have to recompile both Apache 2 and mod_jk from sources however. If there is any need for this info on the Wiki, I can add them.
