1899901 - SAP system does not start: missing "Start_program_X" or "Restart_program_X" parameters

You tried to start the system through the SAP MMC (Windows) or with the "sapcontrol" command, however SAP is not starting: no "dw" (or "disp+work") process is getting created. Further symptoms are:

• Windows only:
• The Windows service related to the affected instance is running (SAP<SID>_$$, where "<SID>" is the "system ID", and "$$" is the instance number);

• Operating System independent:
• You see that the "sapstartsrv" process is running;
• If you open the SAP MMC, it shows the instance in "gray" status, and most of the options are missing (like "AS ABAP WP table");
• No "dev_*" trace file is being created/updated at the "work" folder of the affected instance.
• Command "sapcontrol -nr <instancenumber> -function GetProcessList" returns an empty output:
  
      OS/path>sapcontrol -nr <isntancenumber>  -function GetProcessList

      <timestamp>
      GetProcessList
      OK
      name, description, dispstatus, textstatus, starttime, elapsedtime, pid

      OS/path>
