When you run the Java ES installer, you can select either of these configuration options for Access Manager as well as other Java ES components:
Configure Now: You configure Access Manager and the various Java ES components when you run the installer by choosing options (or using default values). Not all Java ES components support this option.
Configure Later: When you run the Java ES installer, you specify only minimal configuration values. Then, you later configure the specific components by running a script or using an administration console. Access Manager provides the amconfig script and amsamplesilent template file for postinstallation configuration.
If you plan to use BEA WebLogic Server or IBM WebSphere Application Server as the Access Manager web container, you must choose the Configure Later option when you install Access Manager.
