As you wrote - it is a cartesian product.
ok - now it is clear for me.
and in case of simple condition
SELECT E.*, D.*, J.*
FROM EMPLOYEES E, DEPARTMENTS D, JOBS J
WHERE E.DEPARTMENT_ID(+)=D.DEPARTMENT_ID
AND E.JOB_ID(+)=J.JOB_ID
AND E.JOB_ID(+)='FI_ACCOUNT'
AND E.LAST_NAME='Lorentz' --added cond.
ORDER BY E.DEPARTMENT_ID;
;
the AND E.LAST_NAME='Lorentz' --added cond.
will be rewrite to the separeted WHERE clause like this one true?

SELECT e.*, d.*, j.*
FROM departments d
CROSS JOIN jobs j
LEFT JOIN employees e
ON (e.department_id = d.department_id AND e.job_id = 'FI_ACCOUNT' AND j.job_id = e.job_id)
WHERE E.LAST_NAME='Lorentz'
ORDER BY e.department_id
;

Hi, User_TDDEP
The two queries you posted half an hour ago are equivalent. The conditions
AND E.JOB_ID(+)='FI_ACCOUNT'
AND E.LAST_NAME='Lorentz' 
are fundamentally different. The former, using (+), means "don't exclude rows just because of the job_id", but the latter means "do exclude rows if they don't have the right last_name". Another way to get the same results is

SELECT   e.*, d.*, j.*
FROM 	 departments d
JOIN	 employees   e   ON e.department_id = d.department_id
JOIN 	 jobs 	     j	 ON j.job_id 	    = e.job_id
WHERE 	 e.job_id    = 'FI_ACCOUNT'
AND	 e.last_name = 'Lorentz'
ORDER BY e.department_id
;

using inner joins

Hi @User_TDDEP
As you wrote - it is a cartesian product.
so it should be (the script needs to be changed/improved if necessary)
DEPARTMENTS and JOBS are not related, so Cartesian
magic data E.JOB_ID='HR REP' one row
in the older oracle version we will get an error

SQL> /
WHERE E.DEPARTMENT_ID(+)=D.DEPARTMENT_ID
                        *
ERROR at line 12:
ORA-01417: a table may be outer joined to at most one other table

see example (DEPARTMENTS and JOBS have only 2 rows)

with EMPLOYEES (DEPARTMENT_ID,JOB_ID,ENAME)  as
  (select 10,'HR REP','JONES' from dual 
  )
,DEPARTMENTS (DEPARTMENT_ID,DNAME) as
  (select 10,'Administration' from dual union all
   select 210,'IT Support' from dual
  )
,JOBS (JOB_ID,JOB_TITLE) as (
  select 'HR REP','HRR'  from dual union all
  select 'IT_PROG','Programmer'  from dual 
  )
SELECT J.*,E.*, D.*
FROM EMPLOYEES E, DEPARTMENTS D, JOBS J
WHERE E.DEPARTMENT_ID(+)=D.DEPARTMENT_ID
AND E.JOB_ID(+)=J.JOB_ID
AND E.JOB_ID(+)='HR REP'
ORDER BY E.DEPARTMENT_ID
/

What about rewriting this one to ANSI JOIN e.g.
select ts.employee_id from JOB_HISTORY jh,
(SELECT E.*, D.*, J.*
FROM EMPLOYEES E, DEPARTMENTS D, JOBS J
WHERE E.DEPARTMENT_ID(+)=D.DEPARTMENT_ID
AND E.JOB_ID(+)=J.JOB_ID
AND E.JOB_ID(+)='FI_ACCOUNT'
AND E.LAST_NAME='Lorentz' --added cond.
) ts
where jh.employee_id(+)=ts.employee_id;

Hi, User_TDDEP
What about rewriting this one to ANSI JOIN e.g.
Here's one way, that matches the query you posted very closely:

SELECT    ts.employee_id
FROM	  (
	   SELECT   e.*
	   --	   ,		... add columns from tables d and j if wanted
	   FROM   	departments d
	   CROSS JOIN	jobs	    j
	   LEFT JOIN employees      e   ON  e.department_id = d.department_id
	   	    		        AND e.job_id  	    = 'FI_ACCOUNT'
	   			        AND e.job_id        = j.job_id
	   WHERE   e.last_name = 'Lorentz' --added cond.
	  ) ts
LEFT JOIN job_history jh ON jh.employee_id = ts.employee_id
;

It's interesting that the query you posted runs at all, since ts duplicate column names. For some reason, the query I posted raises a "ORA-00918: column ambiguously defined" error if ts has duplicate column names, even though those columns are not used anywhere in the query. If you really want to, you can add all the columns from d and j to the result set of ts, just make sure they have distinct aliases.
Again, since you're essentially doing an inner join with the employees table, the query above is just a convoluted way of saying:

SELECT   e.employee_id
FROM	 departments  d
JOIN	 employees    e  ON  e.department_id  = d.department_id
	   	         AND e.job_id	      = 'FI_ACCOUNT'
JOIN   jobs           j  ON  j.job_id         = e.job_id
LEFT JOIN job_history jh ON  jh.employee_id   = e.employee_id
WHERE   e.last_name = 'Lorentz' --added cond.
