Can a execute the job in parallel.?

Question

Please find below my DBMS_SHEDULER job:
BEGIN
DBMS_SCHEDULER.CREATE_JOB
(job_name => 'job1',
job_type => 'PLSQL_BLOCK',
job_action => 'BEGIN pk_dt_auto.pr_fire_process(''764''); END;'
start_date => SYSDATE,
repeat_interval =>'FREQ = Minutely; INTERVAL = 'SYSDATE+ 30/86400'
END;
Can i run the job twice in parallel?..

Hi,
For dbms_scheduler (and dbms_job) once a job is running it will NOT be started again until after it has finished. The scheduler ensures that only one instance of a job is running at a given time.
There is a way around this however. In your job, instead of doing the manipulations, create a simple one-time job with a unique name (dbms_scheduler.generate_job_name) that does the manipulations. Since creating a job is fairly quick the main job will finish quickly and be rescheduled for after the interval but the one-time job will continue doing the work in the background .
Hope this helps,
Ravi.
