Changing the timing in scheduler jobs

Question

Hi All,
In the below code I have given the execution timing as 2:15. But next run date value is showing as 3:00 AM. What is wrong here?. I created this job at 2:00 AM
SQL> select owner,LAST_START_DATE,NEXT_RUN_DATE from dba_Scheduler_jobs where JOB_NAME='job2' and owner='owner1';
OWNER LAST_START_DATE NEXT_RUN_DATE
owner1 08-DEC-12 03.00.00.000000 AM -
05:00
SQL> BEGIN
2 DBMS_SCHEDULER.create_job (
3 job_name => owner1.job2',
4 job_type => 'PLSQL_BLOCK',
5 job_action => job2();',
6 start_date => '08-Dec-12 2.15.00AM',
7 repeat_interval => 'freq=hourly; byminute=0; bysecond=0;',
8 end_date => NULL,
9 enabled => TRUE,
10 comments => 'None');
11 END;
12 /

Answer 1

the start_date defines the point in time when the schedule becames active. But the time of the next execution is determined by the repeat_interval - in your case: byminute=0; bysecond=0:
BEGIN
  DBMS_SCHEDULER.create_job (
  job_name => 'test_job',
  job_type => 'PLSQL_BLOCK',
  job_action => 'begin null; end;',
  start_date => to_date('08.12.2012 02:15', 'dd.mm.yyyy hh24:mi'),
  repeat_interval => 'freq=hourly; byminute=0; bysecond=0;',
  end_date => NULL,
  enabled => TRUE,
  comments => 'None');
END;
select job_name
     , start_date
     , repeat_interval
     , next_run_date
  from dba_scheduler_jobs
where job_name like '%&job_name%'
   and owner not like 'SYS%'
order by owner
        , job_name
JOB_NAME   START_DATE                          REPEAT_INTERVAL                      NEXT_RUN_DATE
TEST_JOB   08.12.12 02:15:00,000000 +01:00     freq=hourly; byminute=0; bysecond=0; 08.12.12 12:00:00,000000 +01:00
