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.

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 SAP HANA Academy provides free online video tutorials for the developers, consultants, partners and customers of SAP HANA.
Topics range from practical how-to instructions on administration, data loading and modeling, and integration with other SAP solutions, to more conceptual projects to help build out new solutions using mobile applications or predictive analysis.
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.
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.
