  • Script to Refresh Materialized Views

    The following script can be used to refresh materialized views that are capable of FAST (incremental) refresh automatically. Can be used on EBS database as well if you un-comment the commented (REM) lines. The refresh criteria used is any fast refresh-able materialized view that has not been refreshed in the past 24 hours, but was refreshed in the last one month…

    REM Uncomment below line if EBS database
    REM alter session set current_schema=apps;
    
    set serveroutput on size 9999
    
    Declare
    cursor mv2ref is select owner ||'.'||  mview_name mview
           from dba_mviews
           where last_refresh_date between sysdate -30 and sysdate -1
           and fast_refreshable = 'DML';
    dummy pls_integer;
    
    begin
    
    REM Uncomment below line if EBS database
    REM select MRP_AP_REFRESH_S.NEXTVAL into dummy from dual;
    
    for rmv2ref in mv2ref loop
    begin
        dbms_mview.refresh(rmv2ref.mview, 'F');
        dbms_output.put_line(rmv2ref.mview ||' Refreshed at '|| to_char(systimestamp));
    
    exception
    when others then
        dbms_output.put_line(rmv2ref.mview ||' Errored at '|| to_char(systimestamp));
        dbms_output.put_line('    Error: '|| sqlcode ||':'||sqlerrm);
    
    end;
    
    end loop;
    
    end;
    /

    Enjoy!
