Help in Understanding DBMS_JOB.SUBMIT

Question

Hi,
I trying DBMS_JOB.SUBMIT for the first time and i am unable to figure out what is wrong in my code as i dont find any errors.
I have a Procedure Pro_job which has DBMS_JOB.SUBMIT which inturn calls an procedure.
here is the code.
CREATE OR REPLACE procedure Pro_job( P_Number1 IN Number) is
jobno number;
Begin
DBMS_JOB.SUBMIT(job=>jobno,
what => 'P_T.Proc_T(''P_Number1'');');
dbms_output.put_line(P_Number1);
dbms_output.put_line(jobno);
End;
When i compled there are no erros, but this DBMS_JOB.SUBMIT is not triggering or running P_T.Proc_T. And also i want it to run only once with out NEXT_DATE schedule. When i see in DBA_JOBS_RUNNING I find that the job is getting scheduled to run again for the same jobno. which i dont want evern if it fails. Thats the reason why i havnt given any Next_Date in DBMS_JOB.SUBMIT, but still it takes.
Select * from DBA_JOBS_RUNNING
I dont understand which i went work. Can someone guide me on this issue.
Thanks
Sami

You say that it's not triggering or running P_T.Proc_T.
How do you know?
Is it because you can't see the effects of that proc?
You also say that you can see it in DBA_JOBS_RUNNING and that it's getting rescheduled.
This means that the submit has worked.
It also sounds very much like the job is failing.
If the job fails it will retry a number of times before getting set to broken.
If you put some logging in what you're calling (the logging in an autonomous transaction perhaps), it might be more obvious what's happening.
Here's a standalone example of submitting a job, and it running:
SQL> drop table job_test;
Table dropped.
SQL> create table job_test
  2  (col1 date);
Table created.
SQL>
SQL> create or replace procedure p_job_test
  2  as
  3  begin
  4    insert into job_test
  5    values(sysdate);
  6    commit;
  7  end;
  8  /
Procedure created.
SQL> select * from job_test;
no rows selected
SQL>
SQL> declare
  2   l_job integer;
  3  begin
  4   dbms_job.submit(l_job,'p_job_test;');
  5   commit;
  6  end;
  7  /
PL/SQL procedure successfully completed.
