You can use the kill command to stop SAP ASE and Backup Server processes.
When possible, use the Transact-SQL shutdown or shutdown with nowait command. Do not use kill with the -9 flag, because it exits the server without running a checkpoint to ensure that all database changes are written to the database device. SAP ASE may also exit without removing associated shared memory files and network handlers.
kill pid
where pid is the process identification of any dataserver or backupserver process, as determined by the showserver command. Killing one engine for a particular SAP ASE kills all engines for that server.
If more than one SAP ASE is running on the same system, be careful that the engine you kill is associated with the correct SAP ASE. If your SAP ASE is configured to use multiple engines (CPUs), each engine has an associated operating system process. The correct way to kill a multiengine server is to specify the process ID for engine 0.
This showserver output shows the processes for a four-engine server when SAP ASE runs in process kernel mode. In the default threaded mode each engine is not a process, therefore only one process is listed in showserver.

This example shows four running dataserver processes with operating system process identifications (PID) 3320, 3321, 3322, and 3323 (dataserver is the executable form of the SAP ASE program.)
Child engine processes for the dataserver have the -ONLINE: argument.
Each child engine has a parent process identification (PPID) that is equal to the process identification (PID) of the parent. In the example above, the PID of the parent server is 3320. The other three engines spawned by the parent process have the same PPID.
If the PPIDs appear to be unrelated, and there is more than one dataserver process, then more than one SAP ASE is running on the system.
