title: How to schedule a work to run at particular time using dbms_scheduler
body: <p>Im not clear about this, here in DBMS_SCHEDULER we have CREATE_PROGRAM CREATE_JOB CREATE_SCHEDULE etc., after reading the oracle doc still im unclear what to use, On the Oracle side, i am going to use DBMS_SCHEDULER to insert a new message into the queue at the appropriate time, i planned to create scheduler to execute it on particular time and then create program to execute my PL/SQL block which will enqueue the message in the queue Or instead of using CREATE_SCHEDULE and CREATE_PROGRAM, CREATE_JOB does both the jobs, which to use? please guide me whether i am doing correctly, if not please correct me.   </p>
  
  <p>Thankyou</p>
