What does the HDBLCM command '--batch' accomplish during HANA installation?

The HDBLCM command with the '--batch' option is designed to enable an automated installation process for SAP HANA using predefined default options. When this option is specified, it streamlines the installation by bypassing interaction with users, thereby reducing the need for manual inputs and allowing the installation to run automatically based on the defaults set within the configuration. This is particularly useful in scenarios where a consistent installation process is required across multiple environments or when setting up HANA in a system that may not have direct user access.

In contrast, running the installation in verbose mode would provide extensive logging details, while manual installation involves user interaction to specify configurations. Verifying system prerequisites is a step that typically occurs prior to installation but is not the specific function of the '--batch' option as it focuses primarily on automation and efficiency during the installation process.
