Re: Using mod_jk in cluster environment responds HTTP 500
Chris all, Thanks for your help and your responses once again. I now solved the problem. The problem was with the jkmanager URL I was using in the code. I think there is a change in URL attributes from older version. The current version uses vwa, vwr and vwf (which was coded as wa, wr wf respectively). I'm not sure on this but i saw them working on Unix where we have quite older version of Apache and Tomcat installed. Please confirm on this if you have any info. The jkmanager URL i was using previously and the changed URL is given below: Older URL (Works in Unix): - http://localhost/jkmanager/?cmd=updatew=loadbal_hub_prodsw=hub1wf=1wr=hub0wa=2mime=txt Changed URL (Working fine now on Linux): - http://localhost/jkmanager/?cmd=updatew=loadbal_hub_prodsw=hub1vwf=1vwr=hub0vwa=2mime=txt Thanks a lot again.

Re: Using mod_jk in cluster environment responds HTTP 500
Chris, Also one more information: None of my tomcat is configured with HTTP connector. They are configured only for AJP. Does the jkmanager requires this HTTP port? Any relation between the non-SSL HTTP connector and jkmanager? Regards. rikslovein wrote: Thanks for the quick response Chris.

Re: Using mod_jk in cluster environment responds HTTP 500
awarnier, Thanks for your response. I changed this and still it didn't solve my problem. The request are still reaching to the server which I made down using jkmanager. Here's the updated workers.proeprties: worker.list=loadbal_hub_prod,jkstatus worker.loadbal_hub_prod.type=lb worker.loadbal_hub_prod.balance_workers=hub0,hub1 worker.loadbal_hub_prod.sticky_session=false worker.jkstatus.type=status worker.list=hub0 worker.hub0.port=8009 worker.hub0.host=localhost worker.hub0.type=ajp13 worker.hub0.lbfactor=1 #worker.hub0.redirect=hub1 worker.list=hub1 worker.hub1.port=9009 worker.hub1.host=localhost worker.hub1.type=ajp13 worker.hub1.lbfactor=1 #worker.hub1.redirect=hub0 Regards... awarnier wrote: rikslovein wrote: Thanks for the quick response Chris.

Using mod_jk in cluster environment responds HTTP 500
Greeting, I've one apache and two tomcat installed in my server. The communication happens using AJP 1.3. I'm using the jkmanager URL to activate/deactivate the tomcat instances. Also, I'm making sure atleast one of the two tomcat instance is up when other one is down. The problem is sometimes the client request does go to deactivated tomcat instance resulting in HTTP 500 error. I want the request to be redirected only to the active tomcat instance and not the deactivated one. Please suggest how can I do this.
