To start and stop an SAP HANA database using the sapcontrol tool, you can execute the following commands:

1. Start HANA database:
   • sapcontrol -nr <instance_number> -function StartSystem HDB
   • Replace <instance_number> with the number of the HANA instance you want to start. For example, if you want to start instance 00, the command would be:
   • sapcontrol -nr 00 -function StartSystem HDB
2. Stop HANA database:
   • sapcontrol -nr <instance_number> -function StopSystem HDB
   • Replace <instance_number> with the number of the HANA instance you want to stop. For example, to stop instance 00:
   • sapcontrol -nr 00 -function StopSystem HDB

Note: The sapcontrol command requires administrative privileges, so you might need to execute it as a superuser or with appropriate administrative permissions. Also, ensure that the sapcontrol tool is in your system’s PATH or provide the full path to the sapcontrol executable in the command.
