About multiserver configuration
When you install ColdFusion MX 7 using the multiserver configuration, the installation wizard
automatically deploys and configures ColdFusion MX 7 on its own JRun server. This
configuration supports server instance creation in the ColdFusion MX Administrator and lets you
manage ColdFusion MX 7 deployments on multiple JRun servers.
If you already have JRun 4 installed and you want to use the server instance creation feature of
ColdFusion MX 7, you must uninstall it before you install the multiserver configuration of
ColdFusion MX 7.
When you use the multiserver configuration, you can use the ColdFusion MX Administrator to
define multiple server instances on a single computer, each running ColdFusion MX 7. Running
multiple instances of ColdFusion MX 7 has the following advantages:
Application isolation You deploy an independent application to each server instance. Each
server instance has separate settings, and because each server instance runs in its own instance of
the JVM, problems encountered by one application have no effect on other applications.
Load balancing and failover You deploy the same application to each server instance and add
the instances to a cluster. The web server connector optimizes performance and stability by
automatically balancing load and by switching requests to another server instance when a server
instance stops running.
