This document provides an overview of the WebLogic Scripting Tool (WLST) and discusses: - WLST can be used offline to create and modify domains or online to manage running domains. - Offline mode uses the configuration framework to modify domain templates and configs. Online mode uses JMX to interact with managed beans. - Common tasks include deploying applications, starting/stopping servers, and browsing or editing configuration settings and runtime data. - Customizations like adding custom commands or supporting custom managed beans are also discussed.
