Hello, Could you please give an example of "really big sites" ?
How do you organize your cluster (how many members/domains, ...) ? Do you use Farm-deployer ? Do you use session replication ? How do you manage/monitor the cluster ? Many questions, sorry, but I'm currently studying the possibility of setting up a cluster of tomcat 5.5 for a 99.99% available app with lots of user connexions, and I really don't feel confident of my ease with tomcat clustering... Thanks for your answers.

Use Apache/mod_jk >= 1.2.19 with the domain attribute. The mod_jk loadbalancer can then route to the right backup. regards Peter > > --------------------------------------------------------------------- > To start a new topic, e-mail: users@tomcat.apache.org > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Ce message et toutes les pièces jointes (ci-après le « message ») sont confidentiels et établis à l'intention exclusive de ses destinataires.
