Oracle Certified Master For Java EE 5/6 Comes

今天刚发现原来Java EE 也有Oracle Certified Master(OCM)认证了:

 

  • Oracle Certified Master, Java EE 5 Enterprise Architect (includes Sun Certified Enterprise Architect (SCEA)
  • Oracle Certified Master, Java SE 6 Developer (includes Sun Certified Programmer (SCJP)

 

OTN的Ocm Profile 页面:

 

 

不过目前就这2个认证的花名册显示似乎还没有获得者在OTN上注册过:

 

 

 

 

 

Ocm就仅仅是一项认证, 它不能说明持有者的技术水平有多高(虽然我也是), 有些人对认证嗤之以鼻,并且举出这些认证持有者的种种糗事来支持证书无用的观点。

这无可厚非,但是有这么一项认证, 总要比空口无凭的说”我们公司的某某某技术十分好,哪里的谁谁谁水平很高”  来得有力得多。 何况在我眼中,”技术很好” 现在已经完全是一句空话了, 常被用在乙方向甲方介绍外包人才时使用。

这是我对认证的一点不成熟的看法。

 

对于OCM考试的几点意见和建议

Oracle Certified Master(OCM) 大师认证资质是Oracle认证的最高级别。此认证是对技术、知识和操作技能的最高级别的认可。Oracle认证大师是解决最困难的技术难题和最复杂的系 统故障的最佳Oracle专家人选。资深专家级Oracle 技能考试,通过后将成为企业内的资深专家和顾问。OCM 不但有能力处理关键业务数据库系统和应用,还能帮助客户解决所有的Oracle 技术困难。要想获得OCM 证书,必须先通过OCA、OCP考试,再学习两门高级技术课程,然后在Oracle 实验室通过场景实验考试。场景实验考试的目的是测试您的实际问题分析和故障解决能力。

作为一个过来人,我十分愿意分享我对备考OCM的几点建议:

这对于你来说既是一次考试,也是一次系统复习的好机会;OCM考试的面非常广,部分环节可能是你从未实践过的。
准备时间最好不要少于半年,但也千万不要超过半年。
准备阶段使用考纲指定的操作系统,DB,OMS,Clusterware版本。这里推荐在Redhat或Oracle Enterprise Linux 4.7平台上练习,切勿使用windows或windows远程登录练习。
2天的考试是对体力的考验,所以要保证充足的睡眠。
试卷分英语和日语两版;题目文字量较多,需认真阅读;如果对题意并不明了,可以让监考老师进一步解释,一般不会推辞。
很多考试中要求建立的对象可以通过OMS获得SQL语句,确认后输入到SQLPLUS中执行。
部分环节需要十分耐心,如果你不想在屏幕前焦急等待,可以去上个厕所或者泡杯咖啡,总之请放轻松。
如果你不熟悉Grid Control(OMS)界面,那么可以尝试读一下《Oracle.Enterprise.Manager.10g.Grid.Control.Implementation.Guide.2009》,并勤加练习。
考试期间可以阅读10g的官方文档,也可以查询metalink(MOS),前提是在你有足够时间的情况下。
安装配置Grid Control(OMS)是考试的一个高危阶段,这往往决定于你的安装配置经验以及人品,但是一旦出现了问题而你毫无troubleshooting Grid Control的能力,那么就显得事倍功半了。
考试后的hand on是一个”复杂的”过程,请致电OU的800电话。

哪里有深入学习Oracle的资料?

订阅了oracle-l@freelists.org邮件列表(顺便提一下,订阅这个邮件列表也是学习Oracle的好方法,它完全免费,且有许多Oracle界的”大师”出没于此,当然要通过审查才能发言;你可以从freelists.org上找到入口!)的朋友可能在若干天前收到了一封来自Guillermo Alan Bort关于到哪里可以找到学习Oracle内部工作原理资料的邮件。

如何在windows vista/2008/7中 安装Oracle OMS 即Grid Control

之前因为考试的原因,希望能在本机的windows上安装 Oracle OMS 以方便练习,OCM考试中使用的Grid Control 版本为10.2.0.1, 仅支持Windows相关系统号5,对于6或6.1的vista/2008/7安装过程中都会遇到问题无法解决,最为明显的是10.2.0.1自带数据库为10.1.0.4版本在windows相关版本号6以上的平台中均无法创建数据库。Oracle OCM考试中会要求你使用DBCA 建立一个干净的Customer定制数据库,仅需要建立必要的试图和过程(catalog.sql与catproc.sql运行过)并带有label security 组件(其他如Spatial与OLAP组建包括Oracle JVM等均不需要),如图:

Oracle Grid Control 的10.2.0.5版本已经发布,其中10.2.0.4版本已支持最新的Windows操作系统,但只有patch install版本而无直接安装的full install 版本,且直接安装10.2.0.1 版本在OMS configuration部分将出错导致配置失败故我们需要另一种安装方式,如文档 ID:     763072.1

Installing On Windows 2008/Vista

The following sections discuss installing Enterprise Manager 10g Grid Control on Windows 2008/Vista.

Installing Enterprise Manager 10g Grid Control Using A New Database On Windows 2008/Vista

Enterprise Manager 10g Grid Control will not support the New Database install option on Windows 2008/Vista as the Database 10.1.0.4 (which is the default Database for Grid Control) is not supported for Windows 2008/Vista.

Installing Enterprise Manager 10g Grid Control Using an Existing Database On Windows 2008/Vista

To install Enterprise Manager 10g Grid Control using an existing database on Windows 2008/Vista, follow these steps:

  1. Download the fixed OUI 10204 from ARU Microsoft Windows (32-bit) (Bug 6640752) and extract it to a designated location, for example, C:OUI_Shiphome
  2. Copy Enterprise Manager 10g Grid Control 10.2.0.2.0 base shiphome (Disk1) into a location, for example, C:EMGC_102020shiphome
  3. Install the database that supports Vista/2008, such as 10.2.0.3.0/10.2.0.4. Make the following changes in the response file:

    C:EMGC_Shiphome102020shiphomeDisk1installresponseemnoseed.rsp

    1. Give the absolute path of products.xml for the FROM_LOCATION parameter.

      FROM_LOCATION="C:EMGC_102020shiphomeDisk1/oms/Disk1/stage/products.xml"

    2. Give the OMS Oracle Home location. For example:

      ORACLE_HOME=c:emnoseedoms10g

    3. Give the Oracle Home name. For example:

      ORACLE_HOME_NAME=oms10g12

    4. Give the Agent Oracle Home location. For example:

      s_agentHome=c:emnoseedagent10g
