Defining additional server instances

The multiserver configuration is a customized installation of JRun. JRun supports multiple server instances (also called JRun servers) running on the same computer. Each server instance runs in a separate JVM, which executes all ColdFusion pages for that instance.

Use the Instance Manager area of the ColdFusion Administrator to define and manage server instances. The Instance Manager only runs in the cfusion JRun server that is created as part of a multiserver configuration installation.

Note: When you create a server instance using the Instance Manager, if you previously modified the cfusion (Enterprise Manager) instance, the log files for the new instance point to the default cfusion instance. Before you modify the cfusion instance, ensure that you want to share the modification among all new instances.

When you create a server instance with the Instance Manager, by default it deploys a copy of the cfusion server ColdFusion enterprise application, including data sources, mappings, and settings. Alternatively, you can create a server instance and specify the location of an EAR or WAR file (created by the J2EE Archive page), which the Instance Manager uses as the basis for your new ColdFusion server instance.

Note: If you are running JRun 4, you can also create a server in the JRun Management Console (JMC) and deploy the ColdFusion application using JRun deployment functionality.
