[jboss-user] [Clustering/JBoss] - mod_jk 1.2 not distrubuting HTTP requests evenly
I've successfully configured jboss 4.0.5 for clustering and I have to say it was
pretty easy with all the documentation provided by JBoss. Fail over and farming work as
advertised.
I'm currently trying to configure HTTP Session Replication.
My only concern is the mod_jk connector doesn't seem to be distributing the http
requests evenly over the two nodes. The documentation that I've read suggests that
mod_jk should alternate the requests over all of the nodes. In my case, it will alternate
requests over all the nodes but not evenly. What ends up happening is Node 1 will handle
say 9 requests, Node 2 will get 1 request, and then Node 1 gets a bunch more.
I feel like I'm missing something simple here, can anyone point me in the right
direction? Much obliged.
My workers.properties file:
# Define list of workers that will be used
| # for mapping requests
| worker.list=loadbalancer,status
|
| # Define Node1
| # modify the host as your host IP or DNS name.
| worker.node1.port=8009
| worker.node1.host=192.168.1.31

| worker.node1.lbfactor=1
| worker.node1.cachesize=10
|
| # Define Node2
| # modify the host as your host IP or DNS name.
| worker.node2.port=8009
| worker.node2.host=192.168.1.32
| worker.node2.type=ajp13
| worker.node2.lbfactor=1

| # Load-balancing behaviour

My mod-jk.conf file:

| # JkRequestLogFormat
| JkRequestLogFormat "%w %V %T"
|
| # Mount your applications

| # The format of the file is: /url=worker
