Subject RE: IIS 7.5 + AJP Connector

Hi

Sorry, I spoke to soon this is my config.

I set this in my template

worker.template.connection_pool_size=1000
and use the template to create 2 workers and add the 2 workers to a cluster
I am guessing from my testing that the cluster needs one defined as well ! Because each worker
process was limited to ....

So are all the worker properties valid for the a LB worker ?

Alex



# Global Vars
worker.maintain=60
#connection_pool_size=750

worker.list=jbclb
# JBoss cluser
worker.jbclb.type=lb
worker.jbclb.balance_workers=worker1, worker2
worker.jbclb.sticky_session=true
worker.jbclb.method=Request
worker.jbclb.lock=pessimistic

# Template for all worker threads
worker.template.type=ajp13
worker.template.port=8009
worker.template.ping_mode=A
worker.template.ping_timeout=30000
worker.template.connection_pool_size=1000
worker.template.connection_pool_minsize=100
worker.template.socket_keepalive=true
worker.template.lock=pessimistic
worker.template.max_packet_size=65536

# worker 1
worker.worker1.host=10.32.52.151
worker.worker1.route=node1
worker.worker1.reference=worker.template


# worker 2
worker.worker2.host=10.32.52.152
worker.worker2.route=node2
worker.worker2.reference=worker.template
