oracle kill session by sql_id

-- Get Job session IDs
SELECT jr.JOB, s.USERNAME, s.SID, s.SERIAL#, p.SPID, s.LOCKWAIT, s.LOGON_TIME
FROM DBA_JOBS_RUNNING jr, V$SESSION s, V$PROCESS p

-- Or simply a session
SELECT SID, SERIAL#, STATUS, SERVER FROM V$SESSION WHERE USERNAME = '<username>';
-- Kill session with IDs and wait for rollback if any...
ALTER SYSTEM KILL SESSION 'SID,SERIAL#' IMMEDIATE;
