  - 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.

    - Developing and managing content
      Use these tools and processes to develop and manage your website.
    - Delivering web content
      The type of delivery method you use to deliver web content to your viewers depend on the type of content that is being delivered, and the type of viewers your website is intended for.
    - Vanity URLs
      You can associate vanity URLs with portal pages and labels. Vanity URLs are short URLs that people can easily remember. They are shorter than full HCL Portal URLs. They are sometimes also called marketing URLs. You can publish vanity URLs for marketing campaigns through different channels, such as email or print. This way, you can use vanity URLs to direct customers to a specific portal page or content item. Interested site visitors who want to view your campaign can then remember or copy the short vanity URL and type it into the browser address field.
    - Social rendering
      HCL Digital Experience page editors can use social rendering to feature social data that is hosted on a remote HCL Connections server in the context of portal pages.
    - Setting up marketing campaigns
      Use these tools and features to setup marketing campaigns for your website.
      - Personalization
        Portal Personalization provides automatic customization of website content for individual users and user groups.
        How a site is personalized
        Use this topic to understand how to define a personalized list of new articles for a website, such as a section of an intranet site for targeted employee bulletins or where the content of the site is tailored to the particular user.
        Personalization terms
        The concepts and principles for working with Portal Personalization require an understanding of terminology.
        The Personalization interface
        The Portal Personalization user interface consists of three portlets: the Personalization Navigator, Personalization Editor, and the Personalized List.
        Publishing personalization rules overview
        HCL Portal Personalization sends published rules across HTTP to a servlet which resides on each personalization server. This servlet can receive publishing data or initiate new publishing jobs. When a user begins a publishing job from the personalization authoring environment, the local servlet is provided with the set of information necessary to complete the job. The local servlet contacts the destination endpoint servlet (which could be the same servlet) and sends its data to it. The destination servlet reports success or failure.
        The Web Content resource collection
        The Web Content resource collection is installed and configured out of the box. This predefined collection allows you to write rules that select lists of content from HCL Web Content Manager. Rules specify which Web content to show in a Portal Personalization component in Web Content Manager.
        The Portal User resource collection
        Portal Personalization comes with a Portal User resource collection. This collection uses public APIs provided by HCL Digital Experience to access user information.
        LikeMinds Recommendations
        Personalization contains a dynamic recommendation system based on LikeMinds. LikeMinds is software that is used with your e-commerce applications. LikeMinds analyzes user interactions that occur on your Web site and generates real time predictions and recommendations to your Web site users.
        LikeMinds Recommendation Engine architecture
        Get an overview of the functioning and architecture of the LikeMinds Recommendation Engine. In order to build your own recommendation application you need to customize the LikeMinds Recommendation Engine settings to work with your database and Web applications.
        How LikeMinds generates recommendations
        Learn how LikeMinds generates recommendations when a user logs on and navigates through your web site.
        The LikeMinds Recommendation Engines
        LikeMinds Recommendation Engines communicate with a relational database and generate recommendations. Learn about the three types of recommendation engines, Preference engine, Clickstream engine, and Item Affinity engine.
        The LikeMinds utilities
        Get an overview of sifter, buildstats, buildvisit, and accumulator, the utilities that support running of background processes along with the LikeMinds server.
        Configuring LikeMinds
        Use a suitable database modification tool or edit the likemindsdb.properties file to configure your LikeMinds server installation.
        Estimating database size
        The size of your database depends on your application, as well as the number of users and items. View some general guidelines for estimating the size of your database, but your results may vary.
        Database performance
        View some guidelines for performance optimization in your LikeMinds database.
        Scheduling LikeMinds Events
        Use the lps.schedule setting to schedule events to be fired at specific dates and times.
        Configuring the LikeMinds engines
        You can configure your LikeMinds recommendation engines to control aspects such as predictability, number of mentors used, which rating, transaction, or mentor set to use, and so on, for the recommendations returned.
        Configuring the Preference Engine
        The Preference Engine generates recommendations based on users' ratings of items. You can configure the following settings for the Preference Engine.
        Configuring LikeMinds utilities
        You can configure the following settings for the buildstats and buildvisit background utilities.
        Configuring the sifter for mentor selection
        The sifter finds mentors for users, using the information from the rating or transaction data for the LikeMinds server engines.
        Sifter-specific mentor set configuration
        You can specify the following categories of sifter-specific configuration parameters for the following mentor sets.
        How the mentor selection process works
        In order to fully understand the sifter, it is important to have a clear idea of how the mentor selection process works, and how to set configuration parameters that increase the accuracy of your recommendations.
        Sifter performance considerations
        The sifter places high processing demands on the system running it. For this reason it is important to tune it with consideration of its usage and environment.
        Recomputing (rebuilding) the mentor pool
        For better recommendations, you must recompute, or rebuild, the mentor pool at least once a day, ideally at a time when the database has little usage.
        Running multiple sifters
        Use the following settings to run multiple instances of the sifter and have all the sifters share some configuration parameters and override others.
        Preventing multiple sifters from sifting the same user
        When you run multiple sifters simultaneously to distribute load, use the following setting to prevent multiple sifters from sifting the same user in the Lps_User_Data table.
        Number of threads to sift users
        Use this command to set the number of threads to use for sifting users in lpsconfig.
        Sifter sleep time when the Lps_User_Data sift_pri field Is 0
        The Lps_User_Data sift_pri field values must be greater than 0 in order for the sifter to get useful data (that is, updated mentors) for users.
        Time interval for checking sift priority
        To specify the interval in seconds for the sifter to check the sift priority value for a user, use the following setting. The default is 20 seconds.
        Ratability parameters
        The buildvisit background utility computes a ratability value for each item in the database. It is only used for the Preference Engine.
        Repeated items in visit list
        To specify whether the buildvisit utility should repeat an item in the visit list to be shown to a user, set db.visitlist.ratability.duplication_threshold. Items with ratability values greater than this threshold may be repeated.
        Configuring the Clickstream Engine
        The Clickstream Engine generates recommendations based on a record of user shopping behavior as the user navigates through a Web site; that is, a history of user "clicks" during the user's website visit. It uses data such as the items the users view, click, and add to their shopping carts.
        Configuring the Item Affinity Engine
        For every cross-selling transaction in the user's shopping history, the Item Affinity Engine derives its calculations from the following statistics
        Specifying recommendation behavior
        You can configure several parameters that affect the way the LikeMinds server generates recommendations.
        MovieSite Sample
        The MovieSite documentation focuses on six aspects of LikeMinds capabilities.
        Using the LikeMinds utilities
        Learn about the four utilities LikeMinds uses to update the database, buildvisit (for the Preference Engine), sifter, buildstats, and lpsIAA (for the Item Affinity Engine's accumulator utility).
        Filtering LikeMinds recommendations
        When LikeMinds makes recommendations, it can make the recommendations based on all items in your resource collection, or it can limit the predictions to only items that have certain characteristics.
        Feedback and analytics
        Personalization provides a complete logging framework for collecting data on how visitors are using your Web site. If Feedback is enabled, data is automatically collected about each Personalization rule that is fired. In addition, development tools enable websites to collect a variety of data related to visitors' actions and behavior. By default this data is logged to a standard database schema for later analysis and reporting. The framework is also extensible, allowing websites to customize and supplement the way data is collected and stored to more fully meet their needs.
        Developing a personalized portlet
        This exercise demonstrates how to use Personalization features of HCL Portal and Rational Application Developer to build your first personalized portlet. Your final result is a working portlet that uses Personalization rules and content spots to display personal news based on user attributes (or profiles).
