ps -ef | grep ora to find Oracle processes. Be sure to get the process id of the session you are trying to kill
kill -1 <process_id>
or
kill -9 <process_id> |

To kill sessions within the database requires the ALTER SYSTEM privilege and the sid and serial# of the session to be killed
GRANT alter system TO <schema_name>;
SELECT sid, serial#, username, schemaname, osuser
FROM gv$session
WHERE username = <user_name>;
ALTER SYSTEM KILL SESSION '<sid>,<serial#>,<@instance_number>'
