Configuring Linux to install HCL DX

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

1. 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 DX installation file system.

2. Set the file descriptor limit to 10240.

   For example, run the following command to set the file descriptor limit:

   ulimit -n 10240
   

3. 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.

4. 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.

5. 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.
