Thanks for the quick response JB. My question was about accessing multiple Services deployed on the servicemix instances from the mod_proxy_balancer. For example if service1 is available through 'http://hostname:8192/bridge', I would enter below lines in httpd.conf: <Proxy balancer://servicemixcluster> BalancerMember http://host1:8192/bridge BalancerMember http://host2:8192/bridge </Proxy> ProxyPass /servicemix balancer://servicemixcluster lbmethod=byrequests
Now I deploy service2 on host1 and host2 which is available through 'http://hostname:8192/s2', should I be adding the below lines to http.conf? or is there another way out to avoid adding the stanza everytime a new service is deployed? <Proxy balancer://servicemixcluster1> BalancerMember http://host1:8192/s2 BalancerMember http://host2:8192/s2 </Proxy> ProxyPass /servicemix1 balancer://servicemixcluster1 lbmethod=byrequests Thanks in advance for your time, Deepika -----Original Message----- From: Jean-Baptiste Onofré [mailto:[email protected]] Sent: Wednesday, March 10, 2010 6:26 PM To: Deepika Cc: [email protected] Subject: Re: HTTP requests on a servicemix cluster Hi Deepika, The mod_proxy_balancer can support more than two balancer members. It depends on the scheduler algorithm that you use. You can use request counting, weighted traffic counting and pending request counting. You can choose it using the lbmethod. For example, if you use lbmethod=byrequests (request counting), the requests are distributed among the various workers to ensure that each gets their configured share of the number of requests. It works as follows: - lbfactor is "worker's work quota" (the share of amount work to be done) - lbstatus is "how urgent has to work to fulfill its quota of work". You can have more information here: http://httpd.apache.org/docs/2.1/mod/mod_proxy_balancer.html Regards JB Deepika wrote: > Thanks for your response JB.
