Well, start by not configuring the cluster. That should be enough. +1 Formal clustering (in Tomcat) is only useful for session replication. If you don't need session replication, all you need is a load balancer, and you don't really even need to configure it other than to say balance these backend servers in some way (rr, load-based, request-based, etc.). If you are using Apache httpd with mod_jk, then you just need an lb worker with balance_workers set to all the backend workers, and disable sticky sessions (because the default is to use sticky sessions, but you aren't creating sessions, anyway, right?). - -chris -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk/aMlEACgkQ9CaO5/Lv0PCeMQCdE+HGy3kapLL80s5tPH3b6SQr lgUAoMFY5UNxjThMy4WQh1GmRVA/AuLL =g9fq -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Hi Albert, only you have to setup is loadbalancer in front of your tomcat servers. That is all.
