Question

我使用DB链接创建了物化视图。我正面临Oracle 11g2物化视图的一个奇怪问题。当第一次调用时，它有时根据源表更改不反映更改（插入和更新）。当第二次调用相同的MV时，它工作正常。行数可能超过50,000。

请找到MV创建脚本。

CREATE MATERIALIZED VIEW "EMRSODEVAPPUSER"."MV_BM_PNS" ("BM_UNIT", "DATETIME_FROM", "DATETIME_TO", "LEVEL_FROM", "LEVEL_TO")
  ORGANIZATION HEAP PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255
 NOCOMPRESS LOGGING
  STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1
  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
  TABLESPACE "EMRSODEVTBS"
  BUILD IMMEDIATE
  USING INDEX
  REFRESH FORCE ON DEMAND NEXT null
  USING DEFAULT LOCAL ROLLBACK SEGMENT
  USING ENFORCED CONSTRAINTS DISABLE QUERY REWRITE
  AS (select * from (select * from BM_PNS@TRSP04));
   COMMENT ON MATERIALIZED VIEW "EMRSODEVAPPUSER"."MV_BM_PNS"  IS 'snapshot table for snapshot EMRSODEVAPPUSER.MV_BM_PNS';

This is called by DBMS refresh group:

Create the group :

DBMS_REFRESH.MAKE(
name=>'MV_REFRESH_GROUP', 
LIST=>'MV_BM_PNS',next_date => SYSDATE, INTERVAL => 'null');
END;
/   

Execute the group :
execute dbms_refresh.refresh('MV_REFRESH_GROUP');

提前致谢！

Oracle 11g2物化视图不按照给定的计划刷新（插入或更新）
