Tutorial video

For those interested in SAP HANA system administration and changing system properties, we have updated our tutorial video on this topic for SPS 09 in the SAP HANA Academy, playlist System Administration. In this video, we explain how you can configure the INI files to set and unset SAP HANA system parameters using the SAP HANA studio administration perspective or the SQL console.

As documented, SAP does not recommended changing the default values of parameters unless stated in the documentation or instructed by SAP Support. For more information about frequently used parameters, see SAP Note 2036111. Particularly interesting is the attachment to the note, an excellent resource to the Frequently Used Configuration Parameters in SAP HANA.

More Information

Product documentation

Configuring SAP HANA System Properties (INI Files) is documented in the SAP HANA Administration Guide:  Chapter 2, System Administration.

The SQL syntax for changing system parameters is documented in the SAP HANA SQL and System Views Reference: ALTER SYSTEM ALTER CONFIGURATION.

    The information either to restart HDB / not to restart is missing after changing HANA parameter. And there’s no way for us to remember what parameter needs to restart to reflect the changes.

      Hi Nicholas,

      Good point. Wouldn’t it be a great feature when HANA would inform you with a pop-up when you modify a parameter that requires a restart? I will forward this as a request to the development team. Who knows? It may be implemented in a feature release.

      For now – as mentioned – just check SAP Note 2036111

      Here for example are the ones that require a restart for the global.ini file.

      global.ini

      sslCreateSelfSignedCertificate

      Section: inifile_checker

      enable

      Section: multidb

      reserved_instance_numbers

      Section: persistence
