RE: Tomcats in two mod_jk lb-clusters simultaneously
Oh no, I wasn't saying to have cisco loadbalance the tomcats, I was asking why cisco isn't load balancing your apache requests? But yes, your answer is yes. -Tony --- Manager, IT Operations Format Dynamics, Inc. 303-573-1800x27 abia...@formatdynamics.com http://www.formatdynamics.com -Original Message- From: J Channel [mailto:jchann...@gmail.com] Sent: Monday, April 13, 2009 2:37 PM To: Tomcat Users List Subject: Re: Tomcats in two mod_jk lb-clusters simultaneously Cause at first cisco can't balance all tomcats as precision as mod_jk And for example if all tomcats on Server1 dies, or work s sloooww (like 3mins waiting for reply, it can be in our application) but apache still alive - cisco will dont know about it fail and users can give a bad page with nothing =)) Anyway, reply for Q: "Its possible to include a few tomcat servers in two different lb-clusters" is YES? > Why aren't you load balancing to both apaches in a single > cluster instead of having one take all the load and the other in reserve > in case the first fails (as your diagrams seems to show)? > > -Original Message- > From: J Channel [mailto:jchann...@gmail.com] > Sent: Monday, April 13, 2009 11:58 AM > To: Tomcat Users List > Subject: Tomcats in two mod_jk lb-clusters simultaneously > > Im need it for failover issues. > > Is this possible? > Scheme of my idea here: > http://pic.ipicture.ru/uploads/090413/k3k83oomS1.gif - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

RE: Tomcats in two mod_jk lb-clusters simultaneously
I don't see anything not doable in your diagram, although I would take issue with you having your apache servers separated in your cisco load balancer. Why aren't you load balancing to both apaches in a single cluster instead of having one take all the load and the other in reserve in case the first fails (as your diagrams seems to show)? -Tony --- Manager, IT Operations Format Dynamics, Inc. 303-573-1800x27 abia...@formatdynamics.com http://www.formatdynamics.com -Original Message- From: J Channel [mailto:jchann...@gmail.com] Sent: Monday, April 13, 2009 11:58 AM To: Tomcat Users List Subject: Tomcats in two mod_jk lb-clusters simultaneously Im need it for failover issues.
