No Format I think, we need to verify colums widths/datatypes of underlying tables, view, mviews. In case of a join same columns of different tables should have same datatype and column length to make CBO work correctly. On RAC and TEST i set the hidden parameter "_keep_remote_column_size" to TRUE, which will allow mviews to maintain the column size same as its source(banner). We did not have this parameter set to true in production. When we had a problem with mview refresh, we fixed it by altering the column widths of following as below. This was a quick fix from oracle support. I feel, it is worth trying to set this paramter and recreate these two mviews. Thanks, Prabhu alter table BANNER_ENROLLMENTSET modify CATEGORY varchar2(25); alter table BANNER_ENROLLMENTSET modify CREATEDBY varchar2(25); alter table BANNER_ENROLLMENTSET modify LASTMODIFIEDBY varchar2(25); alter table BANNER_ENROLLMENT modify CREATEDBY varchar2(25); alter table BANNER_ENROLLMENT modify LASTMODIFIEDBY varchar2(25); alter table BANNER_CM_SECTION modify CREATEDBY varchar2(25); alter table BANNER_CM_SECTION modify LASTMODIFIEDBY varchar2(25);
