一、創建遠程數據庫連接

create database link MDMconnect to MDMidentified by mdmusing '(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(Host = 172.17.11.1)(PORT = 1521))) (CONNECT_DATA = (SERVER = DEDICATED) (SID= MDM)))';

?

二、創建兩個物化視圖：

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、創建刷新組

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

四、刪除刷新組

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

?
