Stop to build CMDB for your IT - CMS是怎样炼成的？

ITIL在国内的实施也有8年之久，就我看过和做过的项目中：service desk是最多实施的工具，它包括IM/PM；还有Change Management；用户们还可能会常常认为，Release Management可以和变更流程可以混在一起搞。服务台一般先上，有的变更流程先上，服务台的共同特点还有PM一般形同虚设。就我所见所闻的项目和用 户来说，CMDB没有那家能建的好用的好；CMDB的建设的缺失似乎成了所有ITIL用户的通病，应该也是想重点突破的瓶颈。

ITIL v3发布后，CMDB成了CMS中的一个数据库；而且，CMS中包括不止像CMDB这样的配置信息数据库，其实任何保存配置信息的数据库都算在CMS系统 内。既然是一个系统，所以它就不光包含数据还包含一套配套工具集合，通过这套工具，维护和使用配置信息。CMS为其他所有ITIL流程提供基础的配置信 息。它的结构如下图所示：

配置管理系统

如果说上面这幅图比较还是比较抽象的话，那么请见下图：

CMS is a set of tools based on all configuration data

从上图中我们看到，CMS系统一共可以分为四层。上三层是核心CMDB数据库和相关配套工具，最低层Data层则是是所有配置信息的基础来源。从 ITIL v3的角度来说，只建设一个集中的CMDB数据库来存储所有的CI信息是不够的，CMS系统中必须能够包含和处理所有企业已有的各个系统中的配置数据。换 言之，CMDB建设的局限性在于，它只是配置信息数据化，或者说电子化的第一步。

当前依然有很多企业雄心勃勃的上马CMDB项目，不过切记在规划时，一定先好好阅读一下ITIL v3中和CMS相关的内容，适当调整项目的目标和预期总是好的，也可以规避一些项目风险。

CMDB不只是一个数据库那么简单，更不可能在服务台的数据库中建立几张表就可以搞定。从企业IT管理的全局出发，按照 ITIL v3的规范，建设CMS应该是所有ITIL项目的当务之急。CMS系统决不能遗忘过去，必须有效整个现有的各个配置信息数据源，无论其以何种形式存在。它 必须是一个开放的平台，能过最大限度的和其他任何配置信息的消费者（ITIL流程，以及任何需要获取配置信息的任何应用）整合，

以上的一些是我对CMS建设的一些认识。如果要落地到项目上还不许经过一个痛苦的过程，那就是产品选型。选项的过程中可以注重一下几点：

• 可视化：配置项和之间的关系按拓扑形式展现
• 标准化：软件、硬件配置项都有完整标准的CTI信息
• 归一化：与现有各种配置管理系统核心共存同时CMS保持一份完整的户口记录，任何CI都有ID
• 集成化：CMS中的数据以图形或者裸数据等形式供其他相关消费者流程或者人员使用
• 联邦化：CMS核心数据库中不保存动态变化的配置信息（DB的最大连接数，网络设备所使用的syslog服务器地址），这些信息通过联邦管理让用户从其他相关的工具系统中查看到最新的数据。

最近可能还会接触一下CMDB的项目，其他经验总结待续。

It just looks like a Mac desktop

We all knows Mac OS X looks very nice, and works nice also. But, Mac can not be only system for you to use. Most of us are using Intel PC desktops and laptops. You can't have your cake and eat it too. Chinese saying says "鱼和熊掌不可得兼" . So, you might need a new Mac skin for your desktop, no matter MS Windows or Linux OS. I'd like share two tips, you can make a Mac desktop in minutes.

For Windows: FlyakiteOSX is a all-in-one package. It much more easier then making a Mac-buntu. Does it slow down you windows system? Of course, yes. it's just a little bit and acceptable for me.



For Gnome Linux:

There is a open source prject on the SourceForge.net: http://sourceforge.net/projects/mac4lin You need download the package and un-tar it. A pdf document will walk you through every settings. I made my Mac-buntu just in 20 minutes. I do not like 'global meun' and widget, so I ingored them.

Are you on the internet?

Are you really on the Internet? I have to ask this question again. Because there are so many web 2.0 applications and services out there you might don't even know. Here is a list:

• Composite Applications: Mashup, RSS, Atom ...


• Micro Applications: Widgets; Flash...


• Social Networking Applications: Facebook, MYspace, OpenSocial...


• Others:Blog, wiki, Youtube, twitter ...

If you do not know twitter, please check this move out.

从云计算联想到第一代电脑系统

记得以前看过一本描写Bill Gets的书，他上中学的时候，在河滨中心通过一个远程终端，连接到某大学的计算机系统，输入程序代码，并且得到代码在远程电脑系统中的输出，输出好像是在屏幕上出现的，或从打印机上输出的。我基本上忘了那电脑系统的名称，不过它的特点基本上是这样的：当时电脑系统很少，可能全世界上也没有多少台功能全面的电脑；用户使用的特别像是一种计算服务，由于终端设备根本没有技术能力，当时还没有个人电脑；接入方式根本不是tcp/ip更不是internet，当时还没internet。在学习了云计算的一些概念之后，我迷惑了，这个时尚的技术，怎么越看越眼熟啊。

IBM的主机系统可谓是当今电脑世界的恐龙化石级产品，他是一个活化石基本的技术，在经历了开放系统时代之后，我们即将进入云计算时代，我总感觉云计算是一种技术路线的复古。主机系统和第一代电脑系统最相似，区别是可以通过TCP/ip网络，和开放系统通信了。最为一种新兴起的技术，我试图follow http://www.johnmwillis.com/来学习云计算，遗憾的是从08年初以来并没有仔细听他所有的colud cafe；这个老兄在把blog改名为IT Management and Cloud Blog，真可谓是一高产的blogger，这哥们每天能发四五个post，强啊。最近找时间听了一段cloud cafe，我发现到目前为止还没有一个能让大多数人都认同的云计算的概念，基本上对云计算的感念方面有两道三种说法。可以看看 http://en.wikipedia.org/wiki/Cloud_computing 参考这上面的说法也只能有一个模糊的感觉。

看看电脑技术打发展历程：最早的电脑系统，主机系统，开放系统，群集，网格，云计算。前一段时间看过一个非常抢眼的标题“以后世界上将只有5台电脑”。SaaS是一个比较火热的和云计算相关的技术，我认为它像是在web2.0发展到一定阶段后Web应用的一个发展，这方面的强者为salesforce之流。Google和Salesforce不同的是，Google提供网上office套件的同时，还开发他的平台，并提供与之配套的 SDK。Amazon不提供应用也没有SDK，他只提供平台，平台上包括基本的计算和存储服务。Google和Amazon说起来算是基础架构作为一种服务。抛开云计算本身不谈，用户使用和访问的方式并没有发生变化，在任何一个web浏览器存在的地方都能使用或者管理到云计算。客户端的计算和存储能力再次此退化到零，这不能说不是计算机技术发展的返祖现象吧！哈哈～～我也快糊涂了！

OSS应用的常见现象：

1）在某电信构思的招标的答疑过程中，我被问道：你们的系统能支持Linux么？我回答：能支持RHEL 4，5 , SLES. 哦，那你们就说说能支持通用UNIX系统了，我们需要能运行在RHEL，或者RedFlag上。
>>越来越多的用户考虑把IT管理系统安装部署到Linux平台上，并且认为这就是一种UNIX系统，他们以前在商业UNIX系统上的管理也使用经验都能适用于Linux系统。

2）一次用户告诉我他们实在是不能使用Tomcat做为中间件，来运行我们的应用系统，他们必须用BEA。因为他们只有BEA的中间件的管理员，没有Tomcat的管理员。如果上报一个带有Tomcat的系统的话，安全部门不会审批的，因为安全认证还没通过，Tomcat从安全部门的角度讲安全性低。
>>把BEA的管理员不当Tomcat的管理员是人员任用的严谨还是浪费？为什么商业应用比开源应用安全？其实用户自己人也说，这都是制度，他们也无能为力，IT变革势力似乎种弱于工作惯性。

对于中小企业来说，应用某个开源技术难度应该比大企业要小很多。不过大型企业在很多方面也逐渐有，主动应用开源技术的趋势。这在我以前的post中也提到过。从人才的角度和当今的形势看，社会上的linux高手，开源大师其实是越来越多，在经济不景气的当下，开源技术的应用从任何角度上看，可能企业都应该放它到议事日程上了。

Training tips

上周一周都在广州，为中国最大的直销企业Amway做“Remedy Administration Part 2"的培训，这个培训是我今年第5次做；本周用户还给公司发来了感谢信，可见此次培训也是本年效果很好的一次。其实本月对我来说是一个培训月，第一周在新加坡接受一产品培训“BMC Configuration Automation For Network”；第二周在北京给‘中国人寿’做ITIL v3 Foundation的企业内训；第三周在广州，就是这个Remedy的培训。

ITIL v3培训和Remedy培训是两个不同类型的培训，一个是最好实践IT管理方法论的培训；另外一个是Remedy系统管理和开发的课程。一个注重理论的讲解，另外一个是注重实际操作的介绍。不过从讲师的角度来说，培训的准备和整个过程的控制都是殊途同归的。

准备篇
对整课程内容的整体把握是至关重要的，必须对每一个module的内容谙熟于胸，这样才能控制整个培训课程的节奏，才能对时间做到从容地分配。特别是4～5天的培训，把所有的课程从头到尾贯彻为一个整体，不失课程的整体性，让学员有整体感，不觉得你教的内容没有逻辑、琐碎是非常重要的。所以需要在准备课程的时候就想好，每个module之间的衔接方式，要准备好review的问题，从这些问题中总结上一个module，平滑的过度到下一个module，增加课程内容直接的衔接，可以提高学员对内容的整体理解和掌握。

ITIL V3 Traininig For China Life

上周给“中国人寿”做了ITIL V3 Foundation Training， 这是一个定制的企业内训，包括3天的理论学习，一天的‘BSM机场模拟沙盘演练’，最后一天进行ITIL V3 Foundation 认证考试。总的来说培训的效果还是非常不错的，学员基本上都能够理解和掌握ITIL v3的基本理论；在随堂的模拟考试后，能够针对一些题和我做非常深入的讨论。BSM机场模拟沙盘演练对于这群基本上比较年轻的学员来说成了一个非常热烈的培训环节，培训教室温度和气氛都比较热，一轮游戏跑下来以后，有些人就已经是满脸通红了；可见沟通也是一件力气活 :) 从学员们填写的反馈表的结果显示，他们对我的平均满意度是 4.35；呵呵这证明经过多日来的备课准备和以前的项目积累还是比较有效的，相信下次能够比这做的更好。

[项目更新] OCS Inventory NG 1.02 RC3 available and GLPI 0.71.2 available

如果你了解OCS Inventory NG 的话，您可能会发现这个问题，在家里用adsl上网，可能访问不到这个项目的网站，所以要想下载这个项目的软件，可以去sorceforge.net下载。

10/28/2008 OCS Inventory NG Server 1.02 RC3 发布了Patch1，Patch1主要是修复了一些数据库创建和更新的问题，具体的内容如下所示：

In the database creation/update process launched through Administration Console (install.php), défault settings for cache and download directories are missing.

Also, default values in dynamic group computation are not set correctly. So dynamic group of computers are not updated correctly in Communication Server.

We've also included Remi patch in install.php to avoid overriding database username and password if you've changed them. Thanks Remi.
