1. 概述

　　Oracle9iAS 证书全名叫：Oracle9iAS Web Administrator Certified Associate，下文简称 9iAS WACA. 这是 Oracle9iAS 目前唯一的证书. 它不同于 DBA, 因为 DBA 有 OCA，OCP 和 OCM 三种.很多公司现在需要全职或兼职的 Oracle9iAS Web Administrator.这种工作也是 DBA 工作的延伸.很多人在考完 DBA 的OCA/OCP 后加考9iAS WACA 以拓宽自己的知识面和增加工作机会.

　　要得到 9iAS WACA，简单来说：考一门试，得一个证.无参加 Oracle 培训的要求.

　　2.考试

　　9iAS WACA 考试全名: #1Z0-301 Oracle9iAS: Basic Administration. 考试时间为 2 小时.计分题为 83 题. 答对 53 题(63%)为通过. 考试报名等事项与考OCP一样，请参见 Kamus 的“OCP 完全指南”( http://www.itpub.net/showthread.php?s=&threadid=161935 ).

　　3.考试准备

　　要学习,准备下面三方面的内容：

　　1. D37338 Oracle9iAS: Basic Administration, Student Guide V1,V2. Production 2.0 October 2002

　　2. Oracle9i: Security Concepts in an Internet Environment

　　3. Oracle9i: Introduction to LDAP and Oracle Internet Environment

　　参考资料 1 目前还未见有电子版，只有印刷版.网上传过的那本是2001年讲 Oracle9iAS Release One 的，已经很老了.且 Oracle9iAS Release One 和 Release Two 有着本质的不同.学习内容 2 和 3 可通过参加 Oracle 网上图书馆的培训.没有网上图书馆用户的朋友可去 http://www.oracle.com/education/oln/ 免费注册一用户，注册后可试用一个月.可苦干一个月，搞定这两门.

　　4.培训

　　Oracle 提供上述三门课的培训.第一门是由 Oracle 大学的讲师主讲，五天.第二，三门可参加网上图书馆培训.
