  - Overview
    HCL Digital Experience (formerly IBM WebSphere Portal and IBM Web Content Manager) empowers you to create, manage, and deliver engaging omnichannel digital experiences to virtually all audiences with responsive content, targeted offers, seamlessly integrated applications, and consistent branding across channels (web, mobile. and hybrid mobile/web applications and more).

  - Online Help
    This Online Help is made available in the HCL Digital Experience Help Center for quick references on how to install, configure, maintain, and use HCL Digital Experience.
  - 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.

Verbosegc in Java VM logs | HCL Digital Experience

Verbose garbage collection (verbosegc) logging is often required when tuning and debugging many issues, and has negligible impact on system performance.

The default HCL Digital Experience installation enables verbosegc logging and configures the following generic JVM argument:

-Xverbosegclog:${SERVER_LOG_ROOT}/verbosegc.m%d.5/10/13M%S.%pid.txt,20,10000

The verbosegc log file name is verbosegc.m%d.5/10/13M%S.%pid.txt. It includes a date/time stamp and the process ID (PID) of the HCL Portal instance.

The default HCL Digital Experience installation redirects the verbosegc output to 20 rotating historical log files, each containing 10000 garbage collection (GC) cycles.

For more information about configuring the JVM through WebSphere® Application Server, see the IBM® WebSphere® Application Server information centers at www.ibm.com/software/webservers/appserv/was/library.
