Connecting to the NetRegistry MySQL Server
When your database is initially created, you will be issued with a username and password to access your database. NetRegistry gives you full control over your database however, it is MySQL that imposes some limits upon users and allows them to perform only certain functions).

To login through the MySQL client, you will need to use a connection string (which is available from the Technical Support Staff at NetRegistry) similar to the following:

mysql <database> -h caelum.netregistry.com.au -u <username> -p <password>

If you are using other MySQL enabled database management software to login, you will only require the hostname (caelum.netregistry.com.au) and your username and password.

Main Features of MySQL
Below are some of the important characteristics of MySQL and what it supports as listed at http://www.mysql.com/doc/F/e/Features.html:

• Fully multi-threaded using kernel threads. That means it can easily use multiple CPUs if available.

BENEFITS OF VIRTUALIZATION IN ON DEMAND
With virtualization, On Demand customers benefit even further through:

• Simplified solutions;
• Reduced down-time;
• A highly available and serviceable architecture.

Simplified Solutions
The current On Demand policy contains deployment scenarios that require additional physical servers, for example the deployment of a DMZ function or an additional instance. With virtualization, the complexity associated with managing additional servers could be reduced in some cases and in others, may be eliminated altogether. For example:

• A non-production DMZ server could be deployed as a virtual machine and still provide the testing function it serves
• An additional instance could be deployed as a virtual machine in the existing non-production infrastructure

Introduction
MySQL is a popular database with more than 4 million users. It is one of the fastest relational databases in the market. Many companies are using it to support their websites, data warehouses, and business applications. MySQL was developed by a Swedish company named MySQL AB. The product is distributed under GNU General Public License (GPL). It can support multiple users concurrently on the network. Students can connect to a MySQL database server standalone on their own computer or from the network. You can download it free from http://dev.mysql.com/downloads/mysql/4.1.html. MySQL runs on Windows, Linux and Solaris. This tutorial demonstrates using MySQL from the Windows operating system.

Starting and Stopping MySQL Server
If your database server is not started, you can start it by typing “net start mysql” from the MySQL bin directory as shown in Figure 1.1. You can stop it by typing the command net stop mysql.

Preface
This tutorial is a guide to developing enterprise applications for the JavaTM Platform, Enterprise Edition 5 (Java EE 5). This preface contains information about and conventions for the entire Sun Java System Application Server documentation set.

BeforeYou ReadThis Book
Before proceeding with this tutorial, you should have a good knowledge of the Java programming language. A good way to get to that point is to work through The Java Tutorial, Fourth Edition, Sharon Zakhour et al. (Addison-Wesley, 2006). You should also be familiar with the JavaDataBase Connectivity (JDBCTM) and relational database features described in JDBC API Tutorial and Reference, Third Edition,Maydene Fisher et al. (Addison-Wesley, 2003).

HowThis Book Is Organized
The Java EE 5 platform is quite large, and this tutorial reflects this.However, you don’t have to digest everything in it at once. The tutorial has been divided into parts to help you navigate the content more easily.

Introduction

In this tutorial you will learn how to adapt the MX Kollection 3 elements to better fit your existing design and style. All this is done by using the fact that most of the HTML elements inserted by the MX Kollection 3 wizards and server behaviors use CSS files.

Besides choosing from one of the skins provided, you can also create a skin that integrates with your existing site smoothly, in a simple manner.

The application used in this tutorial is the web-site of a small company, that uses for the design an existing template, and for the dynamic elements MX Kollection3 Bundle.

The modules needed to complete this tutorial are:

• The Transaction Engine
• NeXTensio

For the basic operations requested in order to create a new skin, basic knowledge of graphic editing is required, while for more advanced changes, you will need some knowledge of CSS.

Using an electronic messaging system is a common way for today’s corporations to communicate. Quite often, the messaging system becomes an essential method for sharing information and documents, both within and outside of the enterprise. Unfortunately, these same systems can have gaps in security that enable infections to rapidly spread through an organization—posing risks to both data and productivity.
According to an International Computer Security Association (ICSA®) survey, email attachments are the most common sources of infections. Macro viruses, worms, and other malicious code can come in through email to slow down and debilitate your system. For example, infectors such as the Winword Concept macro virus and the Melissa virus have become among the fastest spreading viruses in history. According to the ICSA, the well-known LoveLetter virus is a mass-mailer, and therefore has the potential to spread quickly. The virus arrives as a VBS file attached to an email message.
A 1996 ICSA survey states that macro viruses comprise 49 percent of all viruses detected. Until the Winword Concept virus was born, most viruses lived in and infected only executable regions of magnetic media (like boot sectors) and files (like .EXE, .COM, .BIN, and so on). Now macro viruses have become a common method of delivering infectors. Macro viruses can inhabit and attach themselves to the NORMAL.DOT template of Microsoft Word files on Windows operating systems. Other types of damaging infectors have also become widespread, and variations appear all the time.
Messaging systems pose a special problem for antivirus products because files are stored in a database format, not in a normal file system. No antivirus product can scan such systems by itself. However, eTrust Antivirus can protect users from viruses when documents are detached from messages and saved to the hard drive. It has the unique ability to penetrate the database barrier, and completely scan and cure server-based messaging systems. As a result, macro viruses and other malicious infected files need no longer pose a threat to your company’s messaging/database system.
