Creating materialized view that refreshes every 5 min

Question

I created a materialized view that refreshed every 5 min but when I do insert and perform select on materialized view I get same old data? Do I need to refresh manually?

You can also create a scheduler job:

BEGIN
  SYS.DBMS_SCHEDULER.CREATE_JOB
    (
       job_name        => 'DBAPER.MVW_TEST_REFRESH'
      ,start_date      => TO_TIMESTAMP_TZ('2011/09/02 00:00:00.000000 US/Central','yyyy/mm/dd hh24:mi:ss.ff tzr')
      ,repeat_interval => 'FREQ=DAILY;BYHOUR=6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22;BYMINUTE=0,5,10,15,20,25,30,35,40,45,50,55'
      ,end_date        => NULL
      ,job_class       => 'DEFAULT_JOB_CLASS'
      ,job_type        => 'PLSQL_BLOCK'
      ,job_action      => 'BEGIN 
                            DBMS_MVIEW.REFRESH(''MVW_TEST'',''C'');
                            END;'
      ,comments        => 'Job to refresh materialized view MVW_TEST.'
    );
END;
/

That way you have more configuration options, like excluding night hours or weekends for example.
