PL/SQL執行的作業/過程？

Question

我有這個PL/SQL，並且工作正常也發送電子郵件。

BEGIN 
    FOR cur_rec IN 
     (select JOB, SCHEMA_USER, WHAT from dba_jobs where Broken = 'Y') LOOP 
    BEGIN 
SCHEMA2.send_mail(
      p_to  => 'receive@test.com', 
      p_from  => 'send@test.com', 
      p_subject => 'JOB Report', 
      p_message => 'Job name is: ' || cur_rec.what, 
      p_smtp_host => 'webmail.test.com');  
    END; 
    END LOOP; 
END; 
/

我需要安排的是PL/SQL執行每4個小時，但我不知道如何創建任務或與該代碼的程序，我已經嘗試了很多，但還是說：

完成與警告

任何幫助構建工作和/或過程表示讚賞。

     (select JOB, SCHEMA_USER, WHAT from dba_jobs where Broken = ''Y'') LOOP 
    BEGIN 
SCHEMA2.send_mail(
      p_to  => ''receive@test.com'', 
      p_from  => ''send@test.com'', 
      p_subject => ''JOB Report'', 
      p_message => ''Job name is: '' || cur_rec.what, 
      p_smtp_host => ''webmail.test.com'');  
    END; 
    END LOOP; 
END;', 
    start_date=>sysdate+1, --start tomorrow at this time 
    repeat_interval=>'FREQ=HOURLY; INTERVAL=4', --repeat every 4 hours 
auto_drop=>false 
); 
end;
