2.用户下的job信息
select * from user_jobs;
正在运行的job
select * from dba_jobs_running;

3.创建job
variable jobid number;
begin
  dbms_job.submit(:jobid,'proc_CreateAllStreportData(1);',trunc(sysdate)+18/24,'trunc(sysdate)+1+18/24');
end;
/
show err;

begin
sys.dbms_job.submit(job => :job,
                      what => 'P_CLEAR_PACKBAL;',
                      next_date => to_date('04-08-2008 05:44:09', 'dd-mm-yyyy hh24:mi:ss'),
                      interval => 'sysdate+ 1/360');
commit;
end;
/

4.删除job
exec dbms_job.remove(job_id);
exp:
exec dbms_job.remove(41);
commit;--不加commit是删不掉的

5.运行JOB
 begin
  dbms_job.run(:job1);
 end;
 /

6.中止job
 dbms_job.broken(:job1);
7.修改job
 dbms_job.change(:job,:what,:next_date,:interval);
 dbms_job.what(:job,:what);
 dbms_job.next_date(:job,:next_date);
 dbms_job.instance(:job,:instance); 
 dbms_job.interval(:job,:interval); 
 dbms_job.broken(:job,:broken,:next_date);
