Re: Multiple Tomcat Instances with Linux
Dan, That is essentially the situation I am trying to avoid. There are several applications within an instance of Tomcat that share resources from shared/lib, but those shared/lib resources should not be shared between instances. My goal is to have the separate instances represent independent environments.

Re: Multiple Tomcat Instances with Linux
Dan, Thanks for the post, good ideas I'm going to try them. One thing I'm still not clear on. My application is configured to deploy shared modules (jar files) under CATALINA_HOME/shared/lib. If I create multiple instances, how do I configure the apps to share the correct version of CATALINA_HOME/shared/lib? Do you create a separate document root that contains a shared/lib for each entry in the server.xml configuration?

Re: Multiple Tomcat Instances with Linux
I see this question posted quite often, but rarely answers abound. Is it because this is too complex a topic to explain in a user group? I would think it is fairly common, anyone have ideas?

Multiple Tomcat Instances with Linux
Hello, I'm certain I am behind the curve on this one, but I've been looking around for several days now and haven't found the answers I need. I'm looking to setup multiple environments for Tomcat 4x on a single linux server. One for each developer and several others for different versions of test. >From the mail list archives I've come to understand that CATALINA_BASE can be used to configure multiple instances. However, most examples I've seen use this in coordination with multiple server.xml files. I'm hoping there is a trick to this that I'm missing. I don't mind the extra configuration as long as that is the recommended approach. For an installation supporting a linux service, does the /etc/init.d/tomcat4 script need to be modified to set the CATALINA_BASE for each instance started? Do I need to use different port numbers to access those instances? Is the CATALINA_HOME/shared/lib actually "shared" across instances or can it be unique to an instance according to CATALINA_BASE? Is virtual hosting required to support this type of environment? Any help is appreciated. Thanks, Jon __ Do You Yahoo!? Tired of spam? Yahoo!
