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 product configuration wizards. For components configured by the installer, the installer requires input of the configuration values, and the installation plan lists the configuration values as part of the instructions for running the installer. For components configured after the installer runs, the configuration values are required input for the configuration wizards, and the configuration values are listed as part of the instructions for running 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. Instances are created after the installer runs, by running the component product configuration wizards. The configuration values are required input for the configuration wizards, and the configuration values are listed as part of the instructions for running the configuration wizards.
The selected configuration option applies to an entire installation session. If you need to select different configuration options for some components, you might need to run additional installation sessions.
