Create Job scheduler

Question

Hi,
Apps - 12.1.3
DB - 11.1.0.7.0
i want to run a job ( say sql quesry) at every hour ..
how i can schedule it using scheduler ?
I planned:
--create schedule
begin
dbms_scheduler.create_schedule
( schedule_name => 'weekday_execution',
start_date=> trunc(sysdate)+8/24,
repeat_interval=> 'FREQ=DAILY; BYHOUR=01,02,03,04,05,06,07,08,09,10,11,12,13,14,15,16,17',
comments => 'Weekday schedule based on MON-FRI 8 to 5');
end;
--create program
BEGIN
DBMS_SCHEDULER.CREATE_PROGRAM (
program_name => 'oe.my_saved_program1',
program_action => '/usr/local/bin/date',
program_type => 'EXECUTABLE',
comments => 'My comments here');
END;
Create Job:
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'my_job',
job_type => 'SQL',
job_action => 'select * from dual',
start_date => '01-SEP-11 1.00.00AM US/Pacific',
repeat_interval => 'FREQ=DAILY',
enabled => TRUE,
comments => 'Select query');
END;
Am i correct?
Thanks

Hello Vishwa;
What I is create them in this order
Schedule -
Program Name-
Create Job-
You need to create the Job last if its using a Schedule or a Program. If you query can be run in a stored procedure the Program example below will work.
Schedule Example
begin
  dbms_scheduler.create_schedule 
  (schedule_name => 'DAILY_AT_8AM', 
   start_date=> trunc(sysdate)+18/24, 
   repeat_interval=> 'freq=daily;byhour=8;byminute=0;bysecond=0',
   comments=>' Run at 8am every day'); 
end;
Program Example
begin
-- Call a procedure of a database package
dbms_scheduler.create_program
(program_name=> 'PROG_REPROCESS_EMP_COMM',
program_type=> 'STORED_PROCEDURE',
program_action=> 'REPROCESS_EMP_COMM',
enabled=>true,
comments=>'Procedure to set comm to NULL'
end;
Job Example
begin
dbms_scheduler.create_job
(job_name => 'JOB_REPROCESS_EMP_COMM',
program_name=> 'PROG_REPROCESS_EMP_COMM',
schedule_name=>'DAILY_AT_405PM',
enabled=>true,
auto_drop=>false,
comments=>'Job to update comm to null');
end;You can check for failed jobs by running this query
SELECT
  LOG_DATE,
  JOB_NAME,
  STATUS,
  REQ_START_DATE,
  ACTUAL_START_DATE,
  RUN_DURATION
FROM  
  DBA_SCHEDULER_JOB_RUN_DETAILS
WHERE
  STATUS <> 'SUCCEEDED'Things that will help :
Grant 'create job' or 'create any job' privilege directly to the user (not through a role!).
Avoid naming the job as an already existing procedure/package name.
Consider starting your jobs with JOB_ and your programs with PROGRAM_.
Your Schedule need to be this :
BEGIN
  DBMS_SCHEDULER.create_schedule (
    schedule_name   => 'HOURLY_SCHEDULE',
    start_date      => SYSTIMESTAMP,
    repeat_interval => 'freq=hourly; byminute=0',
    end_date        => NULL,
    comments        => 'Repeats hourly, on the hour, for ever.');
END;
/If you need a code block change you program type to this :
program_type   => 'PLSQL_BLOCK'Best Regards
