//create Jar file
jar -cmf
c:create
f:file
m:manifast
eg. jar -cmf -C ./workspace/jar-test/classes myJarTest.jar *.class
//Extract Jar file
jar -xf
x:extract
f:file
eg. jar -xf myJarTest.jar
// update jar file
jar -uf
u: update
eg. jar uf foo.jar foo.class
//list jar file content as a table
jar -tf
t:table
eg. jar -tf myJarTest.jar
Catalog remote node
catalog tcpip node db2node remote hostname server service_name
uncatalog node db2node
Catalog remote DB2 databases
catalog database db_name as alias_name at node db2node
uncatalog database dbname
List all odbc data sources
list system/user odbc data sources
catalog/uncatalog system/user odbc data source <data source name>
connect to database user name using password
Run sql scripts
To run a script, enter the following command:
db2 -f script_name -o -t -z log_name
db2 –tvf script_name
Describe Table Schema
Describe table <table_name>
Describe Table Indexes
Describe indexes for table <table_name>
Create Index
Create index <index_name> on <table_name>(field1, field2….)
Create unique index <index_name> on <table_name>(field1, field2….) include (field3, field4….) ALLOW REVERSE SCANS COLLECT SAMPLED DETAILED STATISTICS
Drop Index
Drop index <index_name>
Instance-level commands(CREATE DATABASE and FORCE APPLICATION)
Eg.Reslove the table lock
attach to nodename user user name using password
list applications
force application (appid1, appid2)
OR
db2 attach to $DB2INSTANCE
db2 force application all
db2 detach
<Create Your Own Widget Class/>
Creating a Widget Programmatically
var button1 = new dijit.form.Button(params, srcNodeRef);
eg.
new dijit.form.Button({ “class”: “large”, style: “color: red” }, dojo.byId(”someDiv”));
<div id=”someDiv” class=”large” style=”color:red”></div>
Creating a Widget declaratively
eg.
<div dojoType=”dijit.TitlePane” title=”Outer Pane”></div>
IMPORTANT:
startup()
Certain widgets require a startup() method to be called. Haha, java is here again just like GUI, rite?
accordion = new dijit.layout.AccordionContainer({}, dojo.byId(”accordionShell”));
accordion.addChild(new dijit.layout.ContentPane());
accordion.addChild(new dijit.layout.ContentPane());
accordion.addChild(new [...]
<dojo functions/>
1. dojo.require(”dojo.fx”);
//This registers a function to be run when the document (and all required dependencies) are ready
2. dojo.addOnLoad(function(){
console.log(”document ready!”);
});
similarly,
var init = function(){
console.log(”document ready!”);
}
3. dojo.addOnLoad(init);
4. dojo.byId - get DomNode
5. digit.byId – get widget
6. dojo.query – returns a list of Dom nodes based on CSS selector
eg. // every element in the page with the class “blueButton” [...]
XAMPP, Apache, Mysql, PHP, Perl all in one. 开始你网站开发的第一步只需要短短5分钟。

One Sentence定义: Dojo是Javascript的一个框架（开源工具包）。
快速安装:
三种方法：
1. 无安装，直接使用AOL’S 的DOJO(Content Distribution Network)或者google api.
2. 本地安装最新的编译后的dojo.
3. 本地维护dojo源码，编译。
总的来说，使用dojo，都需要编译和装载dojo.xd.js.
1. 使用 CDN/Google提供的dojo. – <推荐>: 想初次体验dojo的初学者
<script type=”text/javascript” src=”http://o.aolcdn.com/dojo/1.0.0/dojo/dojo.xd.js”></script>
<script type=”text/javascript” SRC=”http://ajax.googleapis.com/ajax/libs/dojo/1.3/dojo/dojo.xd.js”></script>
2. 本地使用编译过的dojo – <推荐>大多数开发人员
传统方法： 下载编译好的dojo，放在本地服务器使用。
2.1 http://dojotoolkit.org/downloads下载编译最新版本的dojo
2.2 解压到你自己的项目文件夹下，简单起见，把解压后dojo-版本号文件夹改为dojo。Eg.我把解压后的dojo文件夹放在我项目根目录下（apache server）。浏览器中访问http://localhost/dojo/dijit/themes/themeTester.html， 如果能够看到dojo 测试页面，说明安装成功。
3. 编译源代码，DIY版本dojo – <推荐>高级Javascript开发人员
需要更改，维护源程序，使用自定义级别的dojo. IBM, Google很多大公司自己维护自己的dojo版本以及release.
通过repository (http://svn.dojotoolkit.org/src/)下载源程序,自己维护编译。
