After recent system upgrade, i need a better deployment strategy for Apache Tomcat pair system. recently we upgrade from 2 tomcat app server to three tomcat app server. I need to down the apache server so i can update the mod_proxy_ajp config file to point to a new tomcat app server. the problem occur when i define the wrong port number and i could not debug it fast enough and our company pay a price because of SLA.
I am wondering, is there a apache module that support joining mechanism where once a new tomcat is started, it looks for the apache web server and auto "join" to its existing server pool? Similar to the Jgroup discovery and member joining.
