SQL & PL/SQL :: DBMS Job Commit Other Sessions Automatically

I am calling one procedure through job and after submitting the job i am using commit. problem is when job close the session it commit the code which is inside procedure and as per my understanding in another session also, which i want to avoid .

my procedure is

Create My_proc is
Begin
Insert into my_table values(1,2,3);
End;

And my job proc is

Create my_job_proc is
Begin
dbms_job.submit(jobno,'my_proc;',sysdate,null,null,false);
commit;
End;

now i am calling my job proc is

Declare
Begin
my_job_proc;
End;

Now problem is once it finish, it will insert the data into my_table which i don't want until I call Commit.I already try 'Set autocommit off'
