In the webinar titled "Large Scale Tomcat Deployments", one of the slides describes the option to share config/ across multiple tomcat instances. Specifically, the slide shows the following folder structure:
* A regular Tomcat installrun.sh
* Control scriptshared/
* Shared instance data
* An instance of a Tomcat serverinstance_2/
where the config files (server.xml, tomcat-users.xml) are shared across multiple tomcat instances. How exactly is this accomplished? where is the setting for which I can point to the shared config/ folder?
