    If you are installing the latest version of HCL Digital Experience, migrate your IBM WebSphere Application Server to 9.0.5.
  - Installing and preparing the prerequisite software
    Before you install HCL Digital Experience, make sure that the prerequisite software is installed, configured, and has the required fix packs applied.
  - Installing the HCL Digital Experience software
    The HCL Digital Experience is designed to help create, manage, simplify, and integrate your processes into an engaging online experience.
- 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 HCL Digital Experience to do various day-to-day administration tasks.
- 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.

Database sharing between multiple clusters | HCL Digital Experience

You might want to support multiple identically configured HCL Portal installations in the same cell for ease of maintenance or failover.

If two independently configured clusters exist within the same cell, each cluster must have its own set of database domains. If two clusters that are identically configured exist within the same cell, all database instances must be shared except the release and JCR database domain. All user-specific and community data is shared between clusters, while each cluster’s static configuration can be independently updated.

Database settings

When you configure multiple clusters in the same IBM® WebSphere® Application Server cell, special attention must be given to the database settings.

Based on your configuration case, determine which database domains you want to share with other clusters in the same cell (multiple cluster environment).

Important: JCR domains and release domains cannot be shared between different clusters or servers. Each distinct cluster or server in your environment must use a separate JCR domain and a separate release domain. For example:

Table 1. Examples of separate JCR or Release domains between all clusters or servers when you use Web Content Manager.
Development Server	Authoring Cluster	Staging Server	Delivery Cluster
JCR Domain 1	JCR Domain 2	JCR Domain 3	JCR Domain 4
Release Domain 1	Release Domain 2	Release Domain 3	Release Domain 4

Assign the data source names according to what databases are shared between the clusters and what are unique per cluster. A single data source cannot be used for multiple domains if the domains are a mixture of shared and non-shared.
Maintain the same number of data sources with identical names when enterprise applications are shared across all clusters in the same cell. The data source bindings in the applications can be resolved on every cluster.
When you install the primary node of the next cluster (Cluster B), the node can be configured to use the shared database domains. Set the appropriate property values in the wkplc_dbdomain.properties and wkplc_dbtype.properties files.
