Apache HTTPD 2.2.4, mod_jk 2.2.4, JBoss 4.0.4 GA I configured the mod_jk to work in the failover mode. I shut down the master machine first, then I access my application. I think the mod_jk shoud direct my request immediately to the salve machine. but it takes about one minute to do it. What is wrong with my worker properties? How to solve it? Thanks for your help very much. The following is the content of worker.properties. # Define list of workers that will be used | # for mapping requests | worker.list=loadbalancer,status | | # Define Master | worker.master.host=192.168.225.195 | worker.master.port=8009 | worker.master.type=ajp13 | worker.master.lbfactor=1 | worker.master.cachesize=10 | worker.master.cache_timeout=600 | worker.master.socket_timeout=180 | worker.master.recycle_timeout=100 | worker.master.prepost_timeout=50 | worker.master.recovery_options=0 | | # Define prefered failover node for master | worker.master.redirect=slave | | # Define Slave | worker.slave.host= 192.168.225.116 | worker.slave.port=8009 | worker.slave.type=ajp13 | worker.slave.lbfactor=1 | worker.slave.cachesize=10 | worker.slave.cache_timeout=600 | worker.slave.socket_timeout=180 | worker.slave.recycle_timeout=100 | worker.slave.prepost_timeout=50 | worker.slave.recovery_options=0 | | #Disable slave for all requests except failover | worker.slave.activation=disabled | | # Load-balancing behaviour | worker.loadbalancer.type=lb | worker.loadbalancer.balance_workers=master, slave | worker.loadbalancer.sticky_session=1 | | # Status worker for managing load balancer | worker.status.type=status | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4076677#...
