Using dbms_job but it can't start automatically

Question

I want to use dbms_job for job scheduling in Oracle 8i but got some serious problem.
[Question 1]
If I execute dbms_job like following, I've error :
[Execute]
dbms_job.submit(jobno,
'my_proc',
sysdate,
'sysdate + 1/86400');
[Error]
declare
ERROR at line 1:
ORA-06550: line 1, column 149:
PLS-00103: Encountered the symbol "END" when expecting one of the following:
:= . ( % ;
The symbol ";" was substituted for "END" to continue.
ORA-06512: at "SYS.DBMS_JOB", line 72
ORA-06512: at "SYS.DBMS_JOB", line 140
ORA-06512: at line 18
If I execute dbms_job like following, I've n o error message.
[Execute]
----------------------------------dbms_job.submit(jobno,
'my_proc',
sysdate,
'sysdate + 1/86400',
true,
123,
true);
How come it is required to input such default parameter.
[Question 2]
Even I can submit the job successfully, it can't run automatically.
If I try to force it to run by executing dbms_job.run(jobno, true), I've the following error :
[Error]
ERROR at line 1:
ORA-12011: execution of 1 jobs failed
ORA-06512: at "SYS.DBMS_IJOB", line 394
ORA-06512: at line 1
My config for my server is like this :
job_queue_processes = 2
job_queue_interval = 1
By checking the value from user_jobs, I found that next_date, next_sec are not refreshed and with broken = 'N' and failures = 0.
Sometimes if I restart the server or compile the what "my_proc", the job run automatically.
Can anyone help me to solve it ?

Answer 1

I've found syntax error in your code.
You forgot to put ';' after the call(my_proc) to the procedure. It should look like as mentioned
below.
dbms_job.submit(jobno,
'my_proc;',
sysdate,
'sysdate + 1/86400');
It should work now.
