3. Enter the required information as required. When comes to Enter Target Host Name for Source Host, put in the new hostname.

Local Host Name: OLD-HOSTNAME

System Properties:
SID /hana/shared/SID HDB_ALONE
        HDB15
        version: 2.00.024.04.1530240705
        host: OLD-HOSTNAME (Database Worker (worker))
        edition: SAP HANA Database

Enter Target Host Name for Source Host 'OLD-HOSTNAME' [OLD-HOSTNAME]: NEW-HOSTNAME

4. Define the system usage. We choose 3 as this is our development system.

  Index | System Usage | Description
  -------------------------------------------------------------------------------
  1     | production   | System is used in a production environment
  2     | test         | System is used for testing, not production
  3     | development  | System is used for development, not production
  4     | custom       | System usage is neither production, test nor development

Select System Usage / Enter Index [3]:

5. Define below information as per your system requirement. Other setting should be the same as we are only changing the database hostname.

  Index | Listen Interface | Description
  -----------------------------------------------------------------------------------------------
  1     | global           | The HANA services will listen on all network interfaces
  2     | internal         | The HANA services will only listen on a specific network interface
  3     | local            | The HANA services will only listen on loopback interface (127.0.0.1)

The recommended value for single-host system is 'local'
Select Listen Interface / Enter Index [3]:
