Scheduling stored procedure using DBMS_JOB package

Question

I have stored procedure called “extract_every_day”, I want this procedure to run automatically at 7:00 PM every day.
I used DBMS_JOB.SUBMIT to achieve this, below is pl/sql block
DECLARE
v_jobno number ;
BEGIN
DBMS_JOB.SUBMIT
(v_jobno,
' extract_every_day ',
TRUNC (SYSDATE) + 1 + 9/24,
'TRUNC (SYSDATE) + 1 + 9/24');
COMMIT;
END;
When I run above pl/sql block is that mean procedure “extract_every_day” executes every day and what is the significance of “job” OUT parameter in “DBMS_JOB.SUBMIT “ procedure. Also how can I see list of jobs submitted.
Any help is appreciated.
Thanks

Answer 1

The OUT parameter is the unique number of the job being executed. This is the Sequence generated from sequence sys.jobseq
Also, in the example you have provided, the Job will run at 9Am and not 7PM.
To make it run at 7PM every day change the following lines :
'TRUNC (SYSDATE) + 1 + 9/24'
'TRUNC (SYSDATE) + 1 + 9/24'
To ,
'TRUNC (SYSDATE) + 19/24' <-- Changed
'TRUNC (SYSDATE) + 1 + 19/24' <-- Changed
Also do remember to include the parameter "job_queue_processes" parameter within the init.ora file. This parameter is used to determine the max no
of concurrently running jobs (i.e. Set in Init.ora).
NOTE :- Job_queue_process cannot be set to 0. If set to 0, no jobs is run.
he view dba_jobs and dba_jobs_running should be used to view the jobs.
