一个大实体化视图的刷新（无法执行全量刷新）。

Step Task

1

remove summary Mv from refresh group.
exec dbms_refresh.subtract(name=>'SGREPORTS_REPG', list=>'METRIC_DATA_HOURLY');

2

get the definition of the Mv.
SQL> set long 100000 pagesize 0
SQL> select dbms_metadata.get_ddl('MATERIALIZED_VIEW','METRIC_DATA_HOURLY','SGREPORTS') from dual;

3

drop Mv but preserve the prebuilt table.
drop materialized view METRIC_DATA_HOURLY preserve table;

4

alter table sgreports.metric_data_hourly truncate partition metric_data_hourly_2009_mar update global indexes;

5

On master site:
drop and recreate the MV log.
Create table metric_data_hourly_mar as select * from metric_data_hourly partition (metric_data_hourly_2009_Mar);
grant select on metric_data_hourly_mar to smcrep;
On replication site:
create table metric_hold tablespace LG_DATA
as select /*+ NOPARALLEL(sgreports.metric_data_hourly_mar) */ *
from [e-mail]002A_ZONE01.EAST;
insert /*+APPEND */ into metric_data_hourly
select * from metric_hold;

6

recreate the Mv with the sql got by step 2.
CREATE MATERIALIZED VIEW sgreports.metric_data_hourly on prebuilt table
REFRESH fast with primary key
AS select *
FROM [e-mail]002A_ZONE01.EAST;

7

remove the metric_data_hourlyMv from default refresh group.
exec dbms_refresh.subtract(name=>'metric_data_hourly', list=>'metric_data_hourly');

8

add the mv back to the refresh group.
BEGIN
DBMS_REFRESH.ADD (name=>'sgreports_repg',list=>'metric_data_hourly');
END;
/

9

refresh manually.
exec dbms_mview.refresh('metric_data_hourly','F');
commit;
