  - Installing
    HCL Digital Experience provides flexible deployment options that range from proof-of-concept where you can examine and test functionality to a highly available and scalable production environment. Review the planning information to learn more about hardware and software requirements, high availability, scalability, supported topologies, and much more. Select your operating system and then select the installation pattern that most reflects your business needs.
  - Configuring
    Run the following tasks after you install and deploy HCL Digital Experience. They address tasks that are typically run one time and have a global effect. Some configuration changes are made more frequently or do not have a global effect. These tasks are addressed in the Administering section.
  - Backup and restore
    Backup and recovery of data files and databases is an essential operation for any business system, particularly for data and applications that run in production environments. Create and follow a plan for backing up and recovering data on all tiers of your HCL Digital Experience deployment. IBM Installation Manager must also be included in backup and recovery planning. If you back up the HCL Portal file structure and then install a fix pack, your HCL Digital Experience and IBM Installation Manager become out of sync after you restore the HCL Portal file system. This condition is not recoverable.
  - Migrating
    Successful migration requires significant planning and preparation, understanding the tools that are involved, and careful execution of the appropriate steps in the order provided.
  - Integrating
    Integrate HCL Digital Experience with software such as HCL Sametime to enable your users to collaborate more easily. You can also use the unified task list portlet to integrate HCL with your backend business process software, such as IBM Process Server.
  - Administering
    Use the administration tools that are provided with the portal to do various day-to-day administration tasks. There are two methods for editing portal setup: using the administration portlets or the XML configuration interface. The administration portlets are a convenient way to make real-time updates to the portal's configuration. While the XML configuration interface is suited to more advanced administration, including batch processing of updates.
  - Securing
    Security tasks include setting up property extension databases and custom user repositories, configuring and activating SSL, and configuring authentication. In addition, tasks such as activating Federal Information Processing Standards (FIPS) and NIST SP800-131a security modules and configuring external security managers such as Security Access Manager might be required to secure your portal environment.
  - Monitoring
    HCL Portal includes tools and features to help you monitor the portal site.
  - Setting up a website
    Setting up a website includes, creating pages, adding navigation, setting up search, and adding content to the site. Themes are used to customize the portal's look-and-feel. Out-of-the-box templates and the site wizard can help you set up your portal site faster. You can add wikis and blogs to your site and let users tag and rate content on your site.
  - Staging to production
    During portal solution development, the solution is initially developed, tested, and refined on one server or a limited number of servers. The solution is deployed later on live systems, referred to as the production environment. The process of moving the solution from the development environment to the production environment is called staging.
  - Developing
    This section includes developer documentation on extending applications and development assets for HCL Portal and HCL Web Content Manager.

    - Dojo and HCL Digital Experience
      HCL Digital Experience contains an instance of the Dojo Toolkit, a JavaScript library that is based on the Dojo Toolkit. When you develop components that use Dojo, you must be aware of how the portal uses Dojo, and the tips and restrictions when you use Dojo.
    - Extending HCL Portal class path
    - Developing themes and skins
      You can create themes using modules to contribute to separate areas of pages to provide flexibility, enhance the user experience, and maximize performance. To optimize themes on your website, use the theme optimization module framework. The framework separates feature-specific logic and capabilities from the theme code.
    - URL generation in HCL Portal
      Generating Portal URLs correctly is one of the most important tasks in programming an HCL Portal based application. There are several programming tools and techniques available for generating HCL Portal URLs in custom code. The following section introduces the programming tools available and discusses when it is most appropriate to use each of the tools.
    - Model SPI overview
      Models provide information that is needed by HCL Digital Experience to perform tasks such as content aggregation or building navigation to browse the aggregated content. The information that is aggregated is represented through models that can be accessed programmatically by using the Model SPI (read-only). The information of a model is usually persistent (stored in a database) but can also be transient (computed and stored only in memory). Models can be represented by using a tree structure (nodes have a parent-child relationship), a list structure, or a selection structure (a selected element in a tree structure).
    - Controller SPI
      You can use the Controller SPI for portal administration. It allows you to modify portal resources. It enhances the read-only portal Model SPI by adding writable aspects.
    - User and group management
      The Portal User Management Architecture (PUMA) System programming interface (SPI) provides interfaces for accessing the profiles of a portal User or Group.
    - Portal Access Control interfaces
      Portal Access Control provides interfaces for retrieving and modifying and access control information of portal resources, such as portlets or pages.
    - Developing portlets
      Get an overview of the process of creating portlets, learn about the concepts of the APIs used to develop portlets, and view the samples to get you started. Also, learn about integrating features such as single sign-on, cooperative sharing of information using the property broker, and migrating Struts applications to the portlet environment.
      - Portlet concepts
        Learn about portlets from a user's and an application developer's perspective. View a brief comparison between a portlet and a servlet and understand basic portlet concepts; know the effect of Java 2 security enablement on the operation of portlets that rely on certain privileges for processing.
      - Creating a simple portlet
        To create a simple portlet, you must write the portlet code, compile Java source, create the JAR file, write the portlet descriptors, set up the WAR file directory structure, and package and deploy the portlets.
      - Standard portlet API
        The Java Portlet Specification addresses the requirements of aggregation, personalization, presentation, and security for portlets running in a portal environment.
      - Portlet services
        Portlet services are used to provide common functionality to portlets. Each portlet service has its own service-specific interface for the functionality that it offers.
      - Struts Portlet Framework
        Struts are no longer supported in HCL Digital Experience

      - Client-side aggregation reference
        Refer to programming model guidelines for client-side mode or server-side mode.
      - Portlet communication
        HCL Digital Experience supports multiple ways for portlets to exchange or share information.
        Public render parameters
        Public render parameters allow JSR 286 portlets to share navigational state information. They are specially useful for coordinating the multiple navigation or viewer portlets that display different information items that are all related to the same parameter name. The portal stores all portlet render parameters, including public render parameters, as an encoded part of the current portal URL. Therefore, public render parameters are correctly preserved by typical browser navigation actions such as the Back button and bookmarking.
        Advanced URL generation for data exchange
        For data exchange, HCL Digital Experience supports cross-portlet links
        Standard portlets publish and subscribe mechanisms
        Both JSR 168 and 286 portlets provide communication capabilities that enable you to pass information from one portlet to another. For JSR 286 portlets, these capabilities are included in the JSR 286 standard. For JSR 168 portlets, an extension defined by HCL provides these capabilities. Portlet developers define these capabilities. Portal administrators then determine whether or not these capabilities are used to pass information between portlets.
        Define portlet communication capabilities
        Standard portlets provide powerful publish and subscribe mechanisms for exchanging information by using an action such as semantic invocation. These mechanisms can be used to exchange complex data between portlets and to trigger portlet activity such as updates to back-end systems.
        Triggering communication
        These communication methods are based on directed communication links that pass information from a source portlet to a target portlet.
        Known issues and restrictions related to standard portlets publish and subscribe mechanisms
        Review this information for a list of known issues and restrictions with portlet communication.
        Special purpose techniques for data exchange
        HCL Digital Experience supports special purpose techniques for data exchange.
        Shared portlet sessions
        The following communication methods are based on shared state between multiple portlets. This means that two or more portlets read and write to the same data.

    - How to use remote actions
      Remote actions are used to trigger actions from the HCL Web Content Manager application.
    - How to create custom plug-ins
      A custom plug-in is a reusable Java class that you create to run a task. You can create custom plug-ins such as custom workflow actions, plug-ins to run when a page is rendered, plug-ins to store multi-locale text strings and plug-ins to run when a file is uploaded.
    - Digital Data Connector (DDC) for HCL Portal
      You can use the Digital Data Connector (DDC) for HCL Portal framework to integrate data from external data sources on your portal pages by using HCL Web Content Manager presentation components. External data means that the data does not need to be stored directly in HCL Web Content Manager. For example, you can use DDC to render social data that you have on your HCL Connections server or on other social platforms in the context of your portal pages. Other possible data sources include news feeds, task lists, product catalog information, to name just a few.
    - Determining the current web content context
      To determine the current web content context of a portal page or Web Content Viewer portlet, you can use the WCM Page Context Service. This service provides the ID of the currently rendered item of a page or portlet.
