Q:

Cannot stop/drop job in DBMS_SCHEDULER

I managed to run a job from DBMS_SCHEDULER.  But is running since yesterday and I cannot stop it. 
The code for the job is:  
 begin
  sys.dbms_scheduler.create_job(job_name            => 'FTREC.EXE_1',
                            job_type            => 'EXECUTABLE',
                            job_action          => 'C:\Users\WWLSERVER\Desktop\test.bat',
                            start_date          => to_date(null),
                            repeat_interval     => '',
                            end_date            => to_date(null),
                            job_class           => 'MY_JOB_CLASS',
                            enabled             => false,
                            auto_drop           => false,
                            comments            => '');
 end;

I tried to stop the job/drop it but with no luck. 
When I run:
begin
   dbms_scheduler.stop_job('FTREC.EXE_1',true);
end;

I get no error, but  
SELECT * FROM USER_SCHEDULER_RUNNING_JOBS;

returns EXE_1 and if I try to drop the job  
begin
   dbms_scheduler.drop_job('FTREC.EXE_1',true);
end;

I get this error:
ORA-27478: job "FTREC.EXE_1" is running
ORA-06512: at "SYS.DBMS_ISCHED", line 213
ORA-06512: at "SYS.DBMS_SCHEDULER", line 657
ORA-06512: at line 2

I have restarted the server but I had no luck. 
Any ideas how I can stop/drop this job? 

A:

I want to put the answer in case someone new in Oracle guy face the same problem. 
I had installed a Oracle Remote Agent to run the executable. 
So I had first to stop the service (Oracle Remote Agent) and then stop the job.   
Thank you for your time and your help.
