Problem in Date info at scheduling jobs....

Question

Hi...
I have defined a materialized view ..
create materialized view mv_ekkrem_vlavon
  build immediate
  refresh on demand
  as
select distinct seq_code_eidos .....I want to create a scheduled job using the DBMS_SCHEDULER which will refresh this materialized view ... doing a full refresh of its contents....
so....i following the following steps...-connected as sys:
begin
  dbms_scheduler.drop_job('mv_ekkrem_vlavon_job');
end;
begin
  dbms_scheduler.drop_schedule('mv_ekkrem_vlavon');
end;
begin
dbms_scheduler.create_schedule
('mv_ekkrem_vlavon','15/08/2007 17:20:00','FREQ=DAILY;INTERVAL=1');
end;
exec dbms_scheduler.create_job(job_name=>'mv_ekkrem_vlavon_job',schedule_name=>'mv_ekkrem_vlavon',job_type=>'PLSQL_BLOCK',job_action=> 'BEGIN dbms_mview.refresh(''mv_ekkrem_vlavon''); END;');
exec dbms_scheduler.enable('mv_ekkrem_vlavon_job');However , after 17:20:00 local time (db time) the mv refresh did not take place....
Trying to find out what may be the reason... i issued the following command:
SQL> select job_name,schedule_name,start_date,repeat_interval,last_start_date,next_run_date from dba_scheduler_jobs
  2  where job_name='MV_EKKREM_VLAVON_JOB';
JOB_NAME                       SCHEDULE_NAME                                                                    START_DATE                                                                       REPEAT_INTERVAL                                                                  LAST_START_DATE                                                                  NEXT_RUN_DATE
MV_EKKREM_VLAVON_JOB           MV_EKKREM_VLAVON                                                                 15/08/20 07:17:20,000000 +03:00                                                                                                                                                                                                                    15/08/20 07:17:20,000000 +03:00and issuing the command:
SQL> select to_char(NEXT_RUN_DATE,'dd/mm/rrrr hh24:mi') from dba_scheduler_jobs where job_name='MV_EKKREM_VLAVON_JOB';
TO_CHAR(NEXT_RUN_DATE,'DD/MM/R
15/08/2020 07:17
SQL> Select to_char(START_DATE,'dd/mm/rrrr hh24:mi') from dba_scheduler_jobs where job_name='MV_EKKREM_VLAVON_JOB'
2 /
TO_CHAR(START_DATE,'DD/MM/RRRR
15/08/2020 07:17
Can you find out which is the error in the job definition...????
Needless to write that i use Oracle Db10g.
Many thanks,
Simon

Hi,
The repeat_interval gets its timezone from the start_date parameter so if you want the job to run every 9am in a particular timezone XXX you would need to do something like
START_DATE => SYSTIMESTAMP at time zone 'XXX',
REPEAT_INTERVAL => 'FREQ=DAILY; BYHOUR=9;byminute=0;bysecond=0',
XXX can be something like -2:00 or a named time zone.
There is a dedicated dbms_scheduler forum at
Scheduler
Hope this helps,
Ravi.
