If you use the BI Bus API, you can use optimistic concurrency control to
prevent users from accidentally overwriting each other's changes.
Optimistic concurrency control relies on object versions to detect
conflicting transactions.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Passing Environment Variables to External Applications

You can use a URL to pass environment variables, such as content locale,
to external applications. For example, if a user clicks a link that drills
through to an external application, the content locale environment
variable can be passed through the URL so that the language the user sees
in the report is the same as the language the user sees in the application.

The mandatory building blocks for a URL that passes environment variables
to an external application are as follows:

b_action=xts.run&m=portal/bridge.xts, parameters required to pass the
values of the environment variables

&c_cmd=<command>, to specify the URL-encoded application command to be
executed.

This URL can include application variables, other than environment
variables, to pass to the external application.

&c_env=<variables.xml>, to specify the location of the XML file that
identifies the environmental variables to be passed.

This file must be located under the templates folder in templates/ps.

&c_mode=<get_or_post>, to specify whether to use the get or post request
method when calling the external application.

When you use the post request method, the HTML page created is UTF-8
encoded. When you use the get request method, the values of the variables
are UTF-8 encoded.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

After you create your extended applications, you register them in the
applications index and then deploy the Cognos Extended Applications
portlet to your portal. In addition to the .jar files required to run a
Cognos 8 SDK application, the Cognos Extended Applications portlet must be
deployed with the following files:

The Java standard tag library (JSTL) files jstl.jar and standard.jar. By
default, these files are installed in the
installation_location/Cognos/c8/webapps/samples/WEB-INF/lib directory.

The CPS tag library file cps-sdk-jsptags.jar. By default, this file is
installed in the
installation_location/Cognos/c8/webapps/samples/WEB-INF/lib directory.

The CPS tag library descriptor file cps.tld. By default, this file is
installed in the
installation_location/Cognos/c8/webapps/samples/WEB-INF/tld directory.

cognos sdk study note

MDL represents Transformer models in text format and you can view the text
in any text editor. The .py? file is a representation of the model, stored
in default binary format.

You can use MDL in two ways:
to create an MDL model that completely defines a Transformer model
to create an MDL script that manipulates or updates an existing
Transformer model

ach Transformer model must have at least one model object. The model may
also contain one or more of each of the following object types:

Data Source
PowerCube
Cognos Source (a Cognos 8 package)
PowerCubeGroup
Column
PowerCubeGroupCube
Dimension
Subdimension
Level
Signon
Root Category
View
Drill Category
Custom View
Regular Category
Currency Table
Special Category
Currency
Measure
Dimension Calculation Definition

Automate CleanHouse Sample

This script uses the MDL verb CleanHouse, which is equivalent to selecting
the Clean House command on the Tools menu of the Windows interface,
followed by a date in the format YYYYMMDD. This command removes all
categories with a Last Use date less than the specified date.

Tip: To remove all categories in the model, specify a future date.

This script removes all categories in the Products dimension that have a
Last Use date prior to November 1, 2006, and saves the model.
OpenPy "model.pyj"
CleanHouse Dimension "Product" 20061101 SaveMDL "model.mdl"

transformer documents notes

The Transformer 8.3 executable name is now cogtr.exe on Windows, and cogtr
on UNIX/Linux.

Scale
Decimal values are read into the model based on a scale that you
specify.

You apply security to an entire PowerCube or cube group by setting a
password to restrict access to authorized users.
cogtr.xml seems to be useful.
You can invoke Transformer from the command line to populate models,
create cubes, and perform other actions. How and where these actions are
performed is determined by information that you provide.
Command Line Options

Transformer can perform certain modeling and cube-building tasks from the
Windows, UNIX or Linux command line.

Note: You must invoke the command line utilities from the directory where
the Transformer executable resides. In Transformer 8.3, this is the bin
directory.

This document provides the syntax for the following routine tasks:

creating or updating cubes

updating a model with new categories created during the category
generation process

running a set of batch jobs with different preference settings or input
files

changing the current date setting so that relative time calculations in
batch cube creation are based on a specific date

supplying database signon information

changing the degree of detail for log file messages

opening and deleting checkpoint files

verifying and, if necessary, updating the scales used in MDL model columns
and measures to match those used in the data source

publishing cubes in Content Manager

supporting Cognos 8 prompts

opening specified .mdl files and executing MDL statements

specifying the number of records for a test cube

regenerating categories, and the measure scales used with them, without
building the cube

Cognos sdk dev log

An action is a request made to the FM Engine. Actions are XML elements
that contain input parameters. Some actions also have output parameters.
Actions are defined in the CR1Behaviors.xml file, available in the
<c8-location>\templates\bmt\Cr1Model directory.
Some actions do not change the state of the model in the Framework Manager
application and are not typically recorded in the action logs. An example
of actions that are not recorded are DBBrowse and Publish. There are also
some actions that are recorded but they do not change the state of the
model. An example of this type of action is DBRelease.

Modifying the Log Status of Actions
You can modify the log status of an action to determine whether or not you
want it to appear in the action logs.

Using the Framework Manager SDK

You can use the Framework Manager SDK to perform all the same metadata
modeling tasks and processes as the Framework Manager application. For
example, you can

import a data source

enhance query subjects with SQL, expressions and filters

create model query subjects to extend value of data source query subjects

create a basic package

publish a package to report authors

cognos SDK学习 手记

The Model Schema

The Model schema validates the model.xml file, the xml representation of
the model. The Model Schema reference contains information about the
elements and attributes in the model.xml file.

The Framework Manager application records all the actions you do that
modify the metadata model. These actions are recorded in action logs.
Action logs are XML files that you can re-use and re-run in the Framework
Manager application. You can use these Framework Manager action logs as
examples to help you create your own action logs for the SDK.

cognos sdk 开发手记

Cognos 8 is a solution designed to address the challenges of
enterprise-scale reporting, analysis, scorecarding, and event notification.

The Cognos 8 architecture is based on a typical three-tiered Web
architecture that consists of
*a Web server
The Cognos 8 Web server tier contains one or more Cognos 8 gateways.
*applications
The Cognos 8 applications tier contains one or more Cognos 8 servers. A
Cognos 8 server runs requests, such as reports, analyses, and queries,
that are forwarded by a gateway.
*data
The Cognos 8 data tier consists of the content store, data sources, and
the metric store.

Service-Oriented Architecture

Developers can use a collection of cross-platform Web services, libraries,
and programming interfaces provided with the SDK API to access the full
functionality of Framework Manager. You can use the Framework Manager SDK
to model metadata and publish packages without the use of the Framework
Manager application.

Script Player is a command line utility that runs previously created
action logs to create or modify models, or to publish packages for report
authors. Script Player can run an entire action log or only the part that
is required for a specific task.

Virtually everything you can do with the Cognos 8 graphical user
interface, you can do using the appropriate API, XML file, or command line
utility.

You can manage authorization in Cognos 8 in the following ways:

You can modify users, groups, and roles as defined by your authentication
provider or in Cognos 8. You cannot create users in Cognos 8.

You can control access to objects in the content store, such as folders,
reports, data sources, and configuration objects through the use of
policies.

You can grant capabilities to users, groups, and roles to control access
to specific functionality in Cognos 8.

You can assign access permissions to certain profiles, limiting Report
Studio functionality to specific users, groups, and roles. For more
information about managing profiles,

Running an Object Using the Schedule

The URLs provide a quick and efficient way to start Cognos 8 components
and open specified content, such as reports, metrics, folders, or pages.

You can use the URLs to

start Cognos 8 components

access a Cognos Connection page

You create an extended application by using the CreateURI, URIParameter,
Cognos8Connect, and EncodeNamespace tags in a JSP document.

搬家 >_<

旧房子6.9到期了,算算租了近半年.其中住了2,3个月......(出差真烦),时间到了,房价也要涨回来了.so,找房子.
星期四,心情沮丧,强迫自己不去某个地方,只是为了表示自己不是那么push.然后在路边看到有房屋出租的信息,1200单间,正好符合自己的标准,于是开始看房子.
两间,1200的那个卫生间和之前的那个差不多,pass.另外一个便宜,但是小,pass.
然后就上赶集去看房子啦,两居,1000-1500,牡丹园,打了N多电话,打到信息发布到了5月的了,被喊tooold了.
周末正式开始看房子,一个1400的,房子还行,还算大,没有租过的样子,挺干净,砍价到1350免中介然后去看另外的,虽然只要1000,虽然在二环三环间,但是房间小,比号称的15平缩水一半.
晚上被同住的告知不愿花那么多钱住那么差的地方,郁闷.....
星期六开始找一个人住的地方,看第一个,750,东西挺好,房间只有4平.....缩水一半.恨.
看另外一个键翔园.800一月,隔断,小室内加阳台.感觉还行.同时被告知说还是合租吧.发现该中介还不错,记下了电话,请他吃饭,发现以前做过五星宾馆的门童....
星期一定房子,同住的找的牡丹园的被定了.只好找我找的那个,虽然他们很反复.虽然很混帐,但是需要在9号前找到地方,没有办法.发现房子里面多了个隔断,愤怒,但是被30S告知已经交了定金了就不要妄想降价下来了.
星期二开始,同时被告知需要出差了.想要请人看电影,发现票买不到.恨.然后房子里东西还没有准备好,恨.只好在之前的房间住一个晚上.十点的时候出去看望千里迢迢来北京的张同学.
今天退以前的房子,交接新房子,出差.....
要是有10K的月收入,就可以去租个2500的房子了,也不用弄得这么麻烦了.

我好bt啊.

在网上偷偷的看别人的痕迹.
每打开一个网页都自我感叹一下自己的bt.

今天她还没有回我的短信

是我太push了么?有时候会想为什么总是要折磨自己,这个是自己选择的么?

.

曾经年少的时候想一个人其实也没有什么.但是总是会遇见喜欢的女子.想要做些什么,总是会想很多,很多次,不是想很多东西.如果我是一个有趣的人的话也可以想很多东西出来.别人在评价的时候总是说一个好男人,一个好女人应该具有哪些品质,可是经常他们都忽略了一个重要的点,就是一定要有趣.在古龙的小说里面英雄相逢,或者说江湖人相逢的时候,可以不顾道德,不顾喜好,却常常说'有趣',然后两个人开始喝酒,或许会成为生死之交.所以一个人要是无趣,那他的品行再好,也不过是庙堂之上漂亮的塑像而已. 自己似乎就是这样的一种人.
年少的时候会幻想有种种途径来让自己与天地同寿,终究还是从幻梦中醒过来, 人难免还是要有湮灭的时候,所以就会不再想人生应该如何延长,而是开始想人生如何有意义,然后开始想人生是有意义的么?如果有,那么这个终极意义是什么呢?这是一个被所有有过思想的人所思考过的问题.没有答案,即使有,一个人常常只能被自己的答案所说服.我能找到自己的答案吗?
不过现在明白了,人类不过一种渺小的生物,每个一个独立的人既然是它的一个个体,必然承载了它的缺陷,即他是存在于这个物质世界,是具有能量的,然而也正是这一点,才有了人类的存在,所以说存在本身并不是根本性的,是没有必然性的.所有词句的意义都在于对于主题即对象的描述,既然没有了主体,所以用于描述的,即意义是不存在的.
既然认为人生是没有意义的,那么任何一种行为都是没有意义.对现在的我来说,生活不是无厘头,必然要找到一个意义去吸引我,去驱使我去行动.
当然还是会有行动的时候,人还是会存有感性的时候,对于陌生人的赞美,对于熟悉的人的斥责都会有或喜或悲的反应.总会对物事人有喜好有厌弃.....
有时候简单的执着是没有用的,就像一个傻子一遍遍的用一根棍子在河里网鱼,是不可能有成果的....
虽然自己明白这一点,但是自己是如此的一个无聊人,又有什么办法可以改变呢?
所以会听到莫文蔚在真的吗里面唱I miss you I miss you I miss baby everyday,...I love you I love you I love you baby everyday的时候,真的是眼泪都要流下来了.

Visited the First Auto Work@china

昨天就隐隐约约听到说今天要去参加与汽车相关的活动.今天得知是去一汽参观.倒是有一点吃惊.
车程大概约20-30分钟,然后在一汽的一位同志带领下,参观了一汽的某装配车间.No
photo.
主要参观的是Audi的装配线.也就是从各个零部件装配成整车的流水线.整个装配线共有86个步骤,装配线长度约500米,当然没有算上转弯的部分.每个工序约3分钟时间,需要1-4个工人的工作.整个装配线装配需时约四个小时,整个装配线现在的出货量约是420量,设计年产量为200,000辆/年.
装配工作首先由车身开始,由后到前,由内到外,由上至下.车后盖->内部线->前部->玻璃窗->加上底盘->装上车窗.整个过程主要是手工完成,使用的机器人极少.其中观察到几个有趣的现象,工人师傅用较有韧性的纸条检测后盖的紧密程度,用一个小方块检测车顶的平整?弯曲程度.感觉真是简单而使用的小技巧.装配线上的工人大多都是年轻的小伙子,女性和年纪大的不是很容易见到.另外会同时有不同颜色的同一型号的车从同一装配线下来.
嗯,基本上就是这些.整个车间还是很洁净,声音也不大.不知道是因为生产线是德国生产的原因,车间内挂的标语,警示都有德语标识.
总之,参观完了,感到比较单调,没有什么特别的冲击力,回来的时候看到新中国第一辆解放牌卡车纪念碑,真是让人感叹啊.

老了么?

试了大航海时代,diablo2, 信长之野望,似乎对游戏没有兴趣了?

开始使用linux

其实之前一直没有激励使用linux，最近学了点perl，觉得使用linux的话比较原生态，功能更加强大。正好自己也有了新的笔记本，就装了fedora。
另外提一点就是现在的笔记本好多都是直接提供的vista，感觉特别麻烦，联想的XP的SATA驱动又不好用，勉强装了用着。
选择的是发fedora10的版本。
装好后首先 将用户加到sudoers里面，然后就 yum update了。
然后装了opera，python输入法，然后就来写这个了。
发现可以用linux下面的rdesktop远程登陆，感觉很好用阿。
不过linux还是会有莫名其妙的问题，字符编码也永远是问题。
其它的还好，用得挺习惯的，键盘布局这个挺爽，这样就不用每换一个输入法就设置一个键盘布局了。dvorak也很简单实现了。

2008总结

1月,大四上结束,没有参加马拉松.

how to use svn in eclipes

the orginal post is @ http://blog.punchbarrel.com/2008/06/30/using-the-new-subversion-integration-in-eclipse-ganymede/
Using the new subversion integration in Eclipse Ganymede

Like many other developers I was keen to try out the recent Eclipse Ganymede release. In particular I wanted to try the new subversion integration (”subversive”) to see if it is any better than the old (”subclipse”) plugin I used to use with Europa.

Getting the new subversion working was surprisingly tricky. Obvious choices simply do not work, and the error messages do not give quite enough information to solve the problem. Add to this that some of the names of locations and updates can easily be misconstrued and you have a recipe for confusion.

For example, the error message presented if you try to use the subversive plugin without installing any third-party connectors is the only-partially-helpful:
SVN: ‘0×00400006: Validate Repository Location’ operation finished with error: Selected SVN connector library is not available or cannot be loaded.
If you selected native JavaHL connector, please check if binaries are available or install and select pure Java Subversion connector from the plug-in connectors update site.
If connectors already installed then you can change the selected one at: Window->Preferences->Team->SVN->SVN Client.
Selected SVN connector library is not available or cannot be loaded.
If you selected native JavaHL connector, please check if binaries are available or install and select pure Java Subversion connector from the plug-in connectors update site.
If connectors already installed then you can change the selected one at: Window->Preferences->Team->SVN->SVN Client.

I think the Eclipse folks have potentially missed something important here - checking out a project or three from subversion is almost always the way I start when I want to evaluate an IDE.

Anyway, here are a set of steps which should result in a working Eclipse Ganymede with the new subversion:

Get the basic subversion integration plugin from the eclipse download site
Select Help::Software Updates from the menu bar
Unfold Ganymede::Collaboration Tools
Select SVN Team Provider (Incubation)
Click install… and follow the instructions, including a restart of Eclipse

Resist the temptation to try and use the plugin at this point. It won’t work and you will get the above confusing message about connectors.

Get the third party SVN connectors from a different update site
Select Help::Software Updates from the menu bar
Click Add Site…
Enter http://www.polarion.org/projects/subversive/download/eclipse/2.0/update-site/ and Click OK
Unfold the new site :: Subversive SVN Connectors
Select appropriate connectors. In my case I selected Subversive SVN Connectors, SVNKit 1.1.7, and SVNKit 1.2.0
Click install… and follow the instructions, including a restart of Eclipse

You should now be able to either Window::Show View::Other…::SVN Repositories or Window::Open Perspective::Other…::SVN Repository Exploring and add repositories to your hearts’s content.

Please let me know if your process differs from this, or if you have any corrections or suggestions.

唉唉

感觉总是被欺骗.
执着的付出总是会带来痛苦的.是要痛苦并爱着么?
