      - Preparing the Installation Manager
        The IBM Installation Manager is used to install installation packages such as HCL Digital Experience and IBM WebSphere Application Server.
      - Running the installation program
        Before installing, users need to follow the proven, stable path and must be at the one-level previous version of HCL Digital Experience plus applicable fixes.
      - Post-requisite steps
        The configuration process has changed. Use the Configuration Wizard to set up your integration with databases, LDAPs, clusters, and more.
      - Upgrading the SDK
        Change your version of the SDK Java Technology Edition using the applicable HCL Digital Experience Combined fix pack.
    - Preparing your Windows system for installation
      Installing includes preparing your operating system, installing HCL Portal and HCL Web Content Manager, and completing the deployment configuration.
- 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.

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.

Linux: Preparing your operating system | HCL Digital Experience

Prepare the operating system to ensure a successful HCL Digital Experience installation.

Procedure

If you are using IBM GPFS file sharing, set the file system inodes limit to 25000 or higher.
For example, run the mmchfs /dev/gpfs1nsd -F 250000 command. /dev/gpfs1nsd is the HCL Digital Experience installation file system.
Set the file descriptor limit to 10240.
For example, run the following command to set the file descriptor limit:
```
ulimit -n 10240
```
Updating operating system settings to enable full core dumps:
- Use the ulimit -f command to set the maximum size of files to unlimited.
- Use the ulimit -c command to set the maximum size to cores to unlimited.
For information about these commands, see your operating system documentation.
Install and configure X server on Linux™ (such as X Window System or GNOME) to use the graphical user interface the installation program provides. For information about adding packages, read your operating system documentation.
Note:
- If you plan to install with a response file, X server is not required.
- Installing libXtst.i686 using yum, along with the required prerequisites is sufficient to get the IBM Installation Manager graphical user interface to run.
Ensure that all non-root users have the appropriate permissions to the /tmp/javasharedresources directory.
For example, the non-root users must have at least 770 permissions.
