根据Oracle官方最新消息，自2008年12月1日起，

      欲取得Oracle10g OCA认证必须加考一科考试（Oracle Database SQL Expert，1Z0-047）；

     加了科目后考OCA认证就必须是二门考试(1Z0-042  1Z0-047)

      欲取得进阶的OCP认证，必须先通过OCA认证的两科考试（1Z0-042、1Z0-047），

        以及至少参加过一门門由Oracle讲师教授的课堂训练课程或OLN线上讲师训练课程，

        并通过OCP一科考试（1Z0-043）才能拥有OCP认证。    

而在12月1日前参加1Z0-042考试并通过考试拿到OCA证书的学员不必要加考新增加的考试。
