You can create separate server instances, each with its own ColdFusion applications; each application then has its own ColdFusion and J2EE server resources. In this configuration, you typically have a single external web server with multiple server instances on one computer, and separate virtual hosts (or sites) for each server instance.
Note: Although this section describes using ColdFusion MX, other J2EE application servers provide equivalent capabilities, and most of the concepts apply when deploying the ColdFusion MX J2EE configuration on those J2EE servers.
Running independent applications this way has several advantages, including the following:
-config
option of the jrun
command, which specifies a customized jvm.config file. This is explained in the "Starting and stopping JRun servers" section in Installing and Using ColdFusion MX.Note: These instructions describe creating multiple server instances on a single computer. To create multiple server instances on separate computers, each computer requires a separate license of ColdFusion MX Enterprise Edition.
To achieve complete application isolation, you use web-server-specific functionality to create a separate website for each application. Web servers have different terminology for this concept. For example, in IIS, you define separate websites (available in Windows server editions only) and in Apache, you create multiple virtual hosts.
These instructions apply when running ColdFusion MX in the multiserver configuration. The principles apply when running ColdFusion MX on other J2EE application servers. However, not all J2EE application servers integrate with external web servers. For more information, see Multihoming.
These instructions assume that you deploy each application at a named context root, which enables users to access CFM pages by specifying http://hostname/context-root/pagename.cfm. If other web applications are running in the server instance, each web application must use a different context root.
For example, with a context root of cfmx, users access CFM pages by specifying http://hostname/cfmx/pagename.cfm. For more information on using a context root, see Installing and Using ColdFusion MX.
Note: Although cfmx is the context root, it does not relate to your web application directory structure.
This is different for each web server; for more information, see Multihoming or consult your web server documentation.
