Load Testing Web 2.0 Technologies Ajax-RIA-SOA-Web ServicesWeb 2.0, RIA, AJAX and SOA are terms and abbreviations we hear and use on a daily basis. But do we know what they mean for us as professional performance testers? This document provides an overview of the relevant Web2.0 terms and elaborates on how to run performance tests on these applications. The document targets the performance testing professional as well as the R&D manager looking for information on how to prepare for this new era.
The internet world is evolving with new technologies and architecture models. Web2.0 is a major evolution of Internet applications and provides new options for internet application providers. Web2.0 enables improving the user experience, creating more efficient applications and increasing the productivity of the users and the enterprise.
People most often associate Web2.0 with user-generated content websites, typified by tagging content, blogging, wish lists, and RSS feeds. Some enterprise applications boast a recent Web 2.0 interface called “Enterprise 2.0”, but, issues of performance, privacy and personalization are still blocking many enterprises from adopting this new internet trend. On the other hand technology enablers, such as the SOA system architecture and RIA’s rich UI are likely to eventually converge with Web 2.0 concepts. The combination of different technologies, architectures and concepts will all create new dimensions of internet applications.
RadView, as a leading provider of performance testing software for Internet Applications, provides solutions and guidelines for testing Web2.0 applications. RadView’s current and future product roadmap offers a high level solution enabling developers to secure the Performance, Scalability and ReliabilityTutorial public_html PDFWith an RCI account, you are also allotted a certain amount of web storage space which you can use, for example, to distribute material to a class. Before you can begin sharing files, though, you will need to set up a certain folder on your account, called public_html. public_html is the default name for directories on all Rutgers systems that will include files to be shared over the web, which can be loaded up in any web browser.
The public states that the directory will be available to anyone via a web browser, and the html denotes the fact that web pages and other files will be contained there-in. We can set up this directory in one of two ways in either of the SSH Secure Shell programs. If you prefer to do it via a command-line interface, you can use the command-line terminal window. If you prefer to do it via a graphical user interface, you can do it via the Secure File Transfer Client. This tutorial will explain both; pick whichever one you feel suits you best.

Without the assistance of simplification tools, then, development teams integrating Microsoft Visual Studio 2005 and Microsoft Visual Studio 2008 must re-write and redesign significant amounts of their application build processes. But, such an endeavor proves so costly and time-consuming that many enterprises choose to delay or omit upgrades to their development environments. Unfortunately, avoidance will quickly create a situation where new applications are written in the new Visual Studio but without compatibility to the vast amount of programs and systems that were developed in older versions.
Opportunity
To overcome this development limitation, OpenMake, a CA partner that specializes in Build Management, worked closely with Microsoft on the new Visual Studio 2008 and created a process where Microsoft Visual Studio 2005 code can be easily integrated with code created in the newer release. This unique process bridges the technology gap between the two Microsoft development environments and provides a simple method for programmers to integrate all of their existing applications with new applications written in Visual Studio 2008.
And, the technology is so innovative and complete that even developers using MS Visual Studio 97, MS Visual Studio 6.0 and MS Visual Studio .Net 2002 and 2003 can integrate to MS Visual Studio 2008. As such, it allows you to continue to use the large code base already developed in a single integrated environment and with automated and continuous integrationMaya Basics TutorialHere is the basic Maya Interface: Menu Bar Common Menus – Standard File, Edit, Modify Create, Display, Window menus. Stay constant regardless of mode. Module Specific Menus – Vary based on the Maya module in which you’re operating. For example, you’ll have various polygon manipulation menus when in Modeling, and texturing tools when in Rendering. Status Line Module selector – Let’s you change which Maya module you’re using.
We typically use Modeling, Animation, and Rendering. Scene Icons – basic New, Open, and Save icons. Selection Mode – Let’s you specify how you want to select parts of your scene. By object, or By Component type. Selection Masks – Assuming you’re selecting by component type, these buttons allow you to specify the component on which you’d like to focus Snap Modes – Can be helpful in creating uniform layouts. Essentially objects etc… that you create will move to discrete coordinates as defined by a grid. Render Buttons – Shows you what your scene looks like when fully rendered. Show / Hide Editor Buttons – Lets you control what is seen at the screen’s far right

As you work through it, you will create a sample database and some tables, and then interact with the database by adding, retrieving, deleting, and modifying information in the tables. During the process of working with the sample database, you will learn the following things:
• The basics of the SQL language that MySQL understands. (If you already know SQL from having used some other RDBMS, it would be a good idea to skim through this tutorial to see whether MySQL's version of SQL differs from the version with which you are familiar.)
• How to communicate with a MySQL server using a few of the standard MySQL client programs. As noted in the previous section, MySQL operates using a client/server architecture in which the server runs on the machine containing the databases and clients connect to the server over a network. This tutorial is based largely on the mysql client program, which reads SQL queries from you, sends them to the server to be executed, and displays the results so that you can see what happened. mysql runs on all platforms supported by MySQL and provides the most direct means of interacting with the server, so it's the logical client to begin with.
• This tutorial uses my_super_db as the sample database name, but you might need to use a different name as you work through the material. For example, someone else on your systemOpenOffice.org 2.x Setup GuideThis document is designed to provide users with instructions on installing OpenOffice.org 2.x and its successors on their systems.
Starting with OpenOffice.org 2.x, installation is done using the native installers available on each system. This means that installation only requires that you unpack the download image and then launch the local tool.
Using the native installers will provide better upgrades et cetera. Language packs are mostly available from each Native Language Community and may also be available from http://oootranslation.services.openoffice.org/pub/OpenOffice.org/ plus the appropriate release.
RPM-based Installation
1. Unpack the downloaded image into a directory. For example,Currently, the following command would unpack into the current directory: tar xvzf Ooo_2.0.xxx_LinuxIntel_install.tar.gz .
1. su to root, if necessary.
2. cd into the directory with the unpacked image. This could be RPMS.
3. Then execute rpm -Uvh *rpm for the standard installation in /opt. If you prefer to install in another directory, try rpm -Uvh --prefix // *.rpm or something similar. When relocating, only relocate the base rpms, in other words, do not include any user interface RPMs as these must go in their default locations for proper system integration.
Note: Upgrade the core first and then upgrade the user interface. Separating steps 3 and 4 ensures a good upgrade.
4. cd into the desktop-integration directory and execute rpm -Uvh for the menu rpm that applies to your system. For example, on a RedHat-based system, you would use rpm -Uvh openoffice.org-redhat-menus-.noarch.rpm or similar.
5. Download and install any language packs needed for OpenOffice.org. For example, if you relocated Openoffice.org, you need rpm -Uvh --prefix ///Developing Applications with WebLogic SIP ServerThe SIP Servlet API is a part of JAIN APIs and being standardized as JSR116 of JCP (Java Community Process). The SIP Servlet API version 1.0 was published in February, 2003.
Note: In this document, the term “SIP Servlet” is used to represent the API, and “SIP servlet” is used to represent an application created with the API. J2EE provides Java Servlet that is a main technology of building Web applications. Although Java Servlet is used only to develop HTTP protocol-based applications on a Web application server, it basically has functions as a generic API for server applications. SIP Servlet is defined as the generic servlet API with SIP-specific functions added.
SIP Servlets are very similar to HTTP Servlets, and HTTP servlet developers will quickly adapt to the programming model. The service level defined by both HTTP and SIP Servlets is very similar, and you can easily design applications that support both HTTP and SIP. Listing 1 shows an example of a simple SIP servlet.
Listing 1-1 List 1: SimpleSIPServlet.java
package com.bea.example.simple;
import java.io.IOException;
import javax.servlet.*;
import javax.servlet.sip.*;
public class SimpleSIPServlet extends SipServlet {
protected void doMessage(SipServletRequest req)
throws ServletException, IOException
{
SipServletResponse res = req.createResponse(200);
res.send();
}
}
The above example shows a simple SIP servlet that sends back a 200 OK response to the SIP MESSAGE request. As you can see from the list, SIP Servlet and HTTP Servlet have many things in common:
1. Servlets must inherit the base class provided by the API. HTTP servlets must inherit HttpServlet, and SIP servlets must inherit SipServlet.
2. Methods doXxx must be overridden and implemented.
