批量刷新远程物化视图的方法(备用)

一、创建远程数据库连接

create database link MDM
  connect to MDM
  identified by mdm
  using '(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(Host = 172.17.11.1)(PORT = 1521))) (CONNECT_DATA = (SERVER = DEDICATED) (SID= MDM)))';


 

二、创建两个物化视图:

CREATE MATERIALIZED VIEW DEPARTMENT
TABLESPACE DAT_ICNF
USING INDEX
TABLESPACE IDX_ICNF
REFRESH FORCE ON DEMAND
AS
SELECT * FROM MDM.DEPARTMENT@MDM WHERE TREELEVEL = 1 AND STATUS = '0';

CREATE MATERIALIZED VIEW EMPLOYEE
TABLESPACE DAT_ICNF
USING INDEX
TABLESPACE IDX_ICNF
REFRESH FORCE ON DEMAND
AS
SELECT * FROM MDM.EMPLOYEE@MDM WHERE  STATUS = '0';


三、创建刷新组

execute DBMS_REFRESH.MAKE(NAME=>'MVTAG', LIST=>'DEPARTMENT,EMPLOYEE', NEXT_DATE=>SYSDATE, INTERVAL=>'/*24:HR*/ SYSDATE + 5/(60*24)');
commit;

四、删除刷新组

--execute dbms_refresh.destroy('MVTAG');
--commit;
