What is the command for installing the HANA database using HDBLCM?

The command for installing the HANA database using HDBLCM is indeed the option specifying the batch mode and the action. Using the syntax './hdblcm --batch --action=install' is appropriate because it directs the HDBLCM (HANA Database Lifecycle Manager) to perform the database installation in a non-interactive or unattended mode, which is essential for automation and scripting in deployment scenarios.

The choice to use a batch mode is often preferred in production environments where manual interaction is not feasible due to the need for automated processes. The ‘--action=install’ part clearly indicates to the tool what specific action to take concerning HANA database setup, which directly aligns with the installation process.

Understanding the purpose of each component in the command can clarify its effective use. The './hdblcm' is the command that invokes the HANA database lifecycle management, and the switches --batch and --action provide specific instructions on how the command should execute, making this option the most accurate for installing the HANA database.

Other options do not accurately reflect the correct command structure needed for an automated installation or have incorrect parameters that don't match the action necessary for database installation. Therefore, the method indicated by the correct answer efficiently encapsulates the best practices for deploying
