Preparation
Installation Options:
There are two different approaches provided by SAP for installing the SAP HANA database.
SAP HANA Appliance: For SAP HANA Appliance, it is the complete responsibility of certified hardware partner to perform the installation of HANA components.
Tailored Data Center (TDI) Approach: For TDI approach, it is the responsibility of the certified administrator to perform OS installation and HANA components
Hardware Requirement: SAP HANA is available only for below
Intel Based platforms
IBM Power systems
Software Requirement
As of now SAP HANA supports only the below to Operating System for HANA Database Installation
SUSE Linux Enterprise Server (SLES)
Red Hat Enterprise Linux (RHEL)
In our case we are using Tailored Data Center Integration (TDI) approach with Intel Hardware and SUSE Linux Enterprise Server version 11 and Patch Level 3 with x86_64 architecture. Please make sure we have the RPM packages libgcc_s1 and libstdc++6 installed.
Please refer SAP Note 2228351 - Linux: SAP HANA Database SPS 11 revision 110 (or higher) on RHEL 6 or SLES 11

Please refer SAP Note 2228351 - Linux: SAP HANA Database SPS 11 revision 110 (or higher) on RHEL 6 or SLES 11
Space Requirements: The amount of disk space (data volume log volume) required is based on the disk sizing. Disk space is required to store the data persistently that is kept in memory.
Disk space for data volume = 4*RAM
Disk space for log volume = 1* RAM
Please note that this space does not cover requirement for the backup
File System:
We need the
following file systems to be created before starting the HANA database
installation

4. Extract the file after downloading it will be similar to below
5. Decide SAP HANA System Types from single
and distributed
Single-host system - One SAP HANA instance on
one host.
Multiple-host (distributed) system - Multiple
SAP HANA instances distributed over multiple hosts, with one instance per host. in
our case it was Single host
6. Ask OS team to Setup NTP server so the
time on all the host present in sync.
7. Install SAP Host Agent on all hosts of
the SAP HANA system
8. Make sure Linux kernel value is as per
below

Installation
Procedure:
1. Before starting installation check GUI is enabled from Unix Server. We can check using xclock command as shown in following screenshot.
2. Go to the installation media path where the SAP HANA Database Lifecycle Manager is located
cd <installation media>/DATA_UNITS/HDB_SERVER_LINUX_X86_64/
3. Start the SAP HANA platform lifecycle management tool i.e., ./hdlcmgui
4. Once we run the command ./hdbclmgui following screen will appear. Here in the screen we can see the detected software components. Click on Next
5. Select Install New System Option and click on Next
6. Here I have selected the below 3 other optional components to be installed. Click on Next
7. As shown in the below screen choose System Type as ‘Single-Host system’. And click on Next
8. Here we need to provide the inputs as shown in the below screen and the parameter description as below.
Mandatory Fields: Please provide the SID and Instance number as a mandatory field.
Default Values: Here the installation path and local host name by default it takes the values.
Database Mode: Here we can choose the values as single container or multiple container mode. Here we have selected the single container mode. Please refer the below link https://help.sap.com/saphelp_hanaplatform/helpdata/en/62/3afd167e6b48bf956ebb7f2142f058/content.htm
System Usage: Here we have 4 different usage types for HANA system. I have selected Custom Usage type
Custom – System usage is neither production, test nor development
Test – System is used for testing, not production
Development – System is used for development, not production
Production – System is used in production environment
Restrict Maximum Memory Allocation:
When we enable restricted maximum memory allocation then, Dynamic parameter called global_allocation_limit come into picture and HANA memory utilization is restricted, it is present in global.ini file.
Case1: By default global_allocation_limit=0,HANA use all of its own memory and in case more memory is need then from OS up to 90% of the first 64GB+97%of the rest if available..
Refer SAP Note: 170449 how is default memory allocation limit calculated.
Case2: global_allocation_limit=<value you choose using the slider >
Restart System after machine reboot: if we enable this, when the host is rebooted HANA database will restart
Once all the parameters are provided please check and click on Next
9. In Define Storage properties, we need to specify the Data and log areas. The values will be taken by default as shown below. Please cross check and click on Next
10. In Define Certificate properties phase, we need to provide the Certificate Host name value. By default system takes the current host value. Click on Next
This is required for generation of self-signed SSL certificates for the SAP Host Agent. Please refer to the below link.
https://help.sap.com/saphelp_hanaplatform/helpdata/en/81/f52467fd764f6ab6ee7ade1c6fe9b9/content.htm
11. In Define System Administrator phase , following users will be created during the installation
Here as shown in screen provide the password for the operating system user which will created as part of HANA installation. Make sure password has at least 8 characters.
For Database user SYSTEM, make sure password has at least one Upper case letter.
12. Review the parameters before proceeding further on installation
Once the parameters are check please click on Install Button to proceed with the installation of HANA database
As shown in above screen, some required packages are being installed and instance is being created by the installer.
Once the instance is created as shown below, it is starting all the required services like index server, name server, preprocessor, dispatcher, xsengine
Once the services are started delivery units are being imported by the system as shown in below screenshot.
Once the HANA database is installed, as in below resident hdblcm is being installed as shown
The default location for the resident hdblcm is /sapmnt/<SID>/. Below screenshot showing the resident hdblcm installed on the host.
Once the Resident hdblcm is installed, the component SAP HANA AFL is being installed as shown in below screen. While installing this component system will restart the services.
For installing the SAP HANA database client, it installs the required packages as shown below.
Once it is done HANA studio is being installed as shown below
SSL certificates and host agent configurations are done in Registering SAP HANA Components on Local host phase as shown below in screenshots.
Once all the components are installed we can see the logs as shown below by clicking on view log button
Post Installation Checks
Users Created: Operating system Users Sapadm, hdbadm created as shown below
Check the processes: Login as hdbadm user
Check whether process running or not by using HDB info command as shown below.
Check the installed directories: This check is just a validation purpose.
Check for the directories /hana/data
/hana/log
/hana/shared
Backup: Once the HANA database installation is completed it is recommended to take the backup of SAP HANA system
