2. Weblogic Server is a software product that acts as a
liaison between front end and back end applications.
Weblogic Application Server is widely used for its JMS
capabilities. Later in these sessions we will learn in
detail about Weblogic Installation, Security, JMS and
Clustering.
3. Introduction:
This Installation Guide describes how to use the WebLogic
installation program on Windows and UNIX platforms. This
document is intended for system administrators who are
installing the WebLogic software.
Installation Modes
The installation program can be used in the following modes:
1) Graphical-mode installation:
It is an interactive, GUI-based method for installing software. It
can be run on both Windows and UNIX systems.
4. 2) Console mode Installation:
It is an interactive, text-based method for installing your software from the
command line, on either a UNIX system or a Windows system.
3) Silent mode Installation:
Silent-mode installation is a non-interactive method of installing your
software that requires the use of an XML properties file for selecting installation
options. You can run silent-mode installation from either a script or from the
command line. Silent-mode installation is a way of setting installation
configurations only once and then using those configurations to duplicate the
installation on many machines.

6. Web Servers
Web servers are computers on the Internet that host
websites, serving pages to viewers upon request. This
service is referred to as web hosting. Every web server
has a unique address so that other computers
connected to the internet know where to find it on the
vast network. The Internet Protocol (IP) address looks
something like this: 127.0.0.1.
7. The Internet revolves around the client-server architecture.
Your computer runs software called the client and it
interacts with software known as the server located at a
remote computer. The client is usually a browser such as
Internet Explorer, Netscape Navigator or Mozilla. Browsers
interact with the server using a set of instructions called
protocols. These protocols help in the accurate transfer of
data through requests from a browser and responses from
the server. There are many protocols available on the
Internet. The World Wide Web, which is a part of the
Internet, brings all these protocols under one roof. You can,
thus, use HTTP, FTP, Telnet, email etc. from one platform –
your web browser.
8. Using Logs
WebLogic Server subsystems use logging services to
provide information about events such as the
deployment of new applications or the failure of one or
more subsystems. A server instance uses them to
communicate its status and respond to specific events.
For example, you can use WebLogic logging services to
report error conditions or listen for log messages from
a specific subsystem.
