  • Make sure that you do not run the Software Update Manager during daylight saving time shifts. Otherwise, the update might fail.

  • Always perform the procedure from within the SUM directory.

Context

SAP Host Agent is an agent that can accomplish several lifecycle management tasks, such as operating system monitoring, database monitoring, system instance control, and provisioning. Before you start an update, register the Software Update Manager in SAP Host Agent so that the operations and commands to the updated system are executed using SAP Host Agent mechanisms.

Procedure

  • Register the Software Update Manager for SAP Host Agent as follows:
    • <SUM directory>/abap/SUMSTART confighostagent

  • Optionally, you can customize the user authorization.

    By default, the <SID>adm user is authorized to control the SUM user interface (UI). If you want to authorize a different user, you have to edit the file <HOSTAGENT directory>/exe/operations.d/sumabap.conf as follows:

    1. Add the name of the user for the UI authorization at the end of the following line, separated with a comma:

      Authorization:$[SID:#required#tolower]adm

    2. Restart the SAP Host Agent using the following commands:

      <HOSTAGENT directory>/exe/saphostexec -restart
