1. Log onto UNIX as the SAP administrative user ( <SAP System name>adm ).
2. Enter the following command from your home directory:

• DB stops the database system
• R3 stops the instances and associated processes of the R/3 System
• ALL stops both the database system and the R/3 System. All is the default and can be omitted.

To stop the R/3 System, the startsap script calls kill.sap . kill.sap , in turn, activates shutdown processing in sapstart .
