Get access to the command line or terminal on your linux device and change to a admin user:

	su ndbadm

Change the directory to the HANA installation directory (e.g. /usr/sap/NDB/HDB00)
and stop the HDB process with:

	./HDB stop

Wait until the service has stopped and then type the following to start the service again:

	./HDB start

Once started, log out of the NDBADM user and return to the root user.
Then you may restart the server tools process with:

	/etc/init.d/sapb1servertools restart

After that you may restart the Business One service layer:

	/etc/init.d/b1s restart
