Configuring the tuned Service

Configuring the tuned Service

  1. Run the following command to configure the sap-hana configuration file used by the tuned service.

    NOTE:

    The sap-hana configuration file of the tuned service provided by SLES for SAP 12 includes various hardware configuration, including power regulator and efficiency mode. The configuration in this file will overwrite the OS configuration.

    # zypper install sapconf
    # tuned-adm profile sap-hana
    # systemctl start tuned
    # systemctl enable tuned
    # saptune solution apply HANA (This command applies to SLES 12.2 and later versions but does not apply to SLES 12.1.)

  2. Run the vi /usr/lib/tuned/sap-hana/tuned.conf command, change the value of force_latency to 70, press Esc, and run :wq to save the configuration and exit.

  3. Run the mkdir /etc/systemd/logind.conf.d/ command to create the logind directory.
  4. Run the vi /etc/systemd/logind.conf.d/sap-hana.conf command, add the following two lines, press Esc, and run :wq to save the configuration and exit.
