The installer runs in two different modes, known as Configure Now and Configure Later. The modes differ in the following ways:
In Configure Now mode, the installer configures runnable instances of some, but not all, components. The components configured in Configure Now mode can be started and verified as soon as the installer completes. Runnable instances of the remaining components are created after the installer runs, by running component configuration wizards. For components configured by the installer, your installation plan must include the configuration values you will input when you run the installer. For components that are configured after the installer runs, your installation plan must include procedures for running the configuration wizards and the configuration values you will input when you run the configuration wizards.
A significant feature of Configure Now mode is its ability to install a web container and components that run in the web container at the same time. The installer automatically deploys the components to the web container.
In Configure Later mode, the installer copies component software files to the computer but does not create runnable instances. You create the instances after you run the installer, by running the component configuration wizards. Your installation plan must include procedures for running the configuration wizards and the configuration values you will input when you run the configuration wizards.
The configuration option you select applies to an entire installation session. If you want to install some components on the computer in Configure Now mode and some in Configure Later mode, you must run the installer more than once.
