Product specifications

○ The network interfaces and the udev numbering are defined. If the kickstart process uses DHCP/PXE,

the network parameters used here must be the ones used later on. All parameters must be set by the

OEM.

Avoid network directives using fixed IP on the kernel command line when using DHCP/PXE.

○ Set the host name. In a real environment, this could also be obtained using DNS/BIND.

The SAP HANA installer expects the short version of the hostname without the domain (no FQDN).

○ Modify the file /etc/hosts. This is crucial for the SAP HANA installer to work. It is up to the OEM to

set the array index of IPADDR properly here.

○ Because a proper time synchronization is crucial for SAP HANA to work, NTP is configured. The clock

is synchronized initially in order to avoid clock skew when the service is started. The OEM must

choose the right NTP server here.

○ Set a symbolic link in /usr/lib64 from the latest version of libssl. This is a prerequisite for the

version of SAP HANA tested as by 20/03/2014.

○ Install the database in the unattended mode

○ First, a tarball and the password.xml file must be copied to the local machine. The SERVER

variable holds the IP address of the machine that the file comes from and must be modified by the

OEM.

○ The command line for the installation of SAP HANA in batch mode is as follows:

# LD_PRELOAD=/opt/rh/SAP/lib64/compat-sap-c++.so \

# cat /root/password.xml | "<installation medium>/DATA_UNITS/

HDB_LCM_LINUX_X86_64/hdblcm \

--read_password_from_stdin=xml --sid=ANA --number=00 \

--sapmnt=/hana/shared --datapath=/hana/data --logpath=/hana/log \

--shell=/bin/bash --hostname=$(hostname) -b \

--system_usage=test --autostart=1 --components=server \

--system_usage=test --timezone=CET --max_mem=827052

○ The instance (--sid option) must be changed by the OEM to meet the needs of the

customer.

○ The parameter --max_mem limits the overall memory usage of SAP HANA.

○ For an explanation of the various options, please go to the installation directory and refer to

# ./hdblcm --action=install --help

○ The same applies for the password.xml file containing the admin passwords (see below).

○ You can ignore the checks performed by the SAP HANA installer (for installation on virtual

systems for example) by appending ignore statements to the previous line

○ --ignore=check_hardware

○ --ignore=check_min_mem

○ As explained above, the installer can be provisioned with a password file. The following is an

example of the password file in XML syntax:

<?xml version="1.0" encoding="UTF-8"?>

<sapadm_password>Agent1234</sapadm_password>

<system_user_password>Sys1234</system_user_password>

<root_password>Root1234</root_password>

</Passwords>
