Q22: What is the difference between the Configure Now and Configure Later configuration types?

Answer: The installer gives you the option of performing initial configuration for many of the Java ES components during installation.

• Configure Now This configuration type prompts you to enter the initial configuration values during the installation session. Configure Now can be selected for only some components. If you select components for Configure Now that cannot be configured during installation, the installer indicates that it will not configure them. You will configure them after installation.

  • Components that can be configured during installation include Access Manager, Application Server, Directory Server, HADB, Portal Server, Portal Server Secure Remote Access, Web Server, and Web Proxy Server.

  • Components that cannot be configured during installation include Directory Proxy Server, Java DB, Monitoring Console, Service Registry, and Sun Cluster software .

• Configure Later This configuration type instructs the installer to copy component software packages to the host. You might be asked to enter a few values that are necessary for copying the packages. The installer proceeds without doing further configuration, and no runnable instances are created. You create runnable instances after installation by supplying configuration values when prompted by component configuration wizards or in configuration files. You can select Configure Later for all components.

The configuration type that you selected (Configure Now or Configure Later) applies to an entire installation session.

Regardless of whether you perform the initial configuration in the installer (Configure Now) or manually after installation, there is usually some additional postinstallation configuration required. See Q28: What postinstallation configuration is required?
