For a batch mode (non-interactive) installation of an SAP HANA database system using the hdblcm tool, all essential information must be provided upfront. The SAP HANA System ID (SID) is a fundamental, unique identifier for the system and has no default value, making it a mandatory parameter. Similarly, the password for the sapadm user, the administrator for the SAP Host Agent, is mandatory. This password is required to register the new SAP HANA instance with the SAP Host Agent, which is a critical step for system management and monitoring. The installation cannot proceed in batch mode without these two parameters.

A. Data and log path: These are not mandatory. If these paths are not specified, the hdblcm installer will automatically use default locations derived from the installation path and SID (e.g., /hana/data/).

B. Installation path: This is not mandatory. The installer uses a default shared installation path (typically /hana/shared) if a specific path is not provided by the administrator.

1. SAP HANA Server Installation and Update Guide for SAP HANA Platform 2.0 SPS 07

Section 3.2.2

"Installing an SAP HANA System Using the Command-Line Interface". This section details the parameters for the hdblcm tool. The parameter reference table explicitly lists sid and sapadmpassword as required for the installation action.

sid=: "Required. Specify the system ID of the new system."

sapadmpassword=: "Required. Specify the password of the SAP Host Agent user (sapadm)."

The guide also confirms that parameters like datapath and logpath have default values

making them optional.

SAP HANA Platform: Installation Parameters Reference

Section "install Action Parameters". This official reference guide provides a comprehensive list of all parameters for the hdblcm tool.

Under the install action

the sid parameter is explicitly marked as "Required".

The sapadmpassword parameter is also marked as "Required".

In contrast

parameters such as datapath

logpath

and sapmnt (installation path for the shared directory) are listed with default values

confirming they are not mandatory for the command to execute.
