Named Configurations

A named configurationis an abstraction that encapsulates Application Server property settings. Clusters and standalone server instances reference a named configuration to get their property settings. With named configurations, J2EE containers’ configurations are independent of the physical machine on which they reside, except for particulars such as IP address, port number, and amount of heap memory. Using named configurations provides power and flexibility to Application Server administration.

To apply configuration changes, you change the property settings of the named configuration, and all the clusters and standalone instances that reference it pick up the changes. You can only delete a named configuration when all references to it have been removed. A domain can contain multiple named configurations.

The Application Server comes with a default configuration, called default-config. The default configuration is optimized for developer productivity in Application Server Platform Edition and for security and high availability in the Application Server Standard and Enterprise Editions.

You can create your own named configuration based on the default configuration that you can customize for your own purposes. Use the Admin Console and asadmin command line utility to create and manage named configurations.
