Siebel Web Architecture - Overview

The Siebel Web Architecture

At a high level, the Siebel Web architecture consists of:

•  Siebel Web Clients that access and display the business data
• A Gateway Name Server that stores configuration information
• A Web server that handles interactions with the Web Clients and distributes requests to the Siebel Servers
• Servers that manage the business data and provide batch and interactive services for clients
• A relational database and file system that store business data

Web Usage Login Scenario

Siebel Web Client (browser) sends the URL to the Web server

 URL specifies:

• Either HTTP or HTTPS protocol
• Web server machine name
• Application and language

 URL initially connects to a Siebel-specific virtual directory on the Web server

·         Virtual directories are created as part of the Siebel installation

·         Virtual directory forwards request to the Siebel Web Server Extension (SWSE) installed on the Web server

·         SWSE uses the eapps.cfg configuration file to obtain connection parameters

Eapps.cfg specifies the location of the server, server connection broker port, Enterprise, and Object Manager information for initial connection

•  For multi-server installations provides load balancing information
• Also provides generic login information for initial “anonymous” access to database

Siebel Gateway Name Server

Stores component definitions and assignments, operational parameters, and connectivity information

•  For example, connect strings to query servers for server/component availability
•  Information stored in siebns.dat file on Gateway Name Server

Siebel Enterprise

• Is a logical collection of Siebel Servers that support users and access a single database server and the Siebel file system
• Logically groups Siebel Servers for common administration via Siebel Server Manager
• Supports sharing of common configuration information

Siebel Servers

Execute tasks to manage the business data

• Programs known as server components perform specific functions or jobs for the server
•  For example:
•  Importing and exporting data
• Configuring the database to monitor for user-defined conditions
•  Processing of client requests

•  Tasks may run interactively, in the background, or as batch jobs

Siebel File System

Is one or more shared directories that store files used by Siebel applications

•  Files are compressed in a proprietary format to save space and provide security
•  Examples: Product literature, sales tools, presentations, user profiles

Database Server

• Stores data used by Siebel applications in a predefined database schema
• Single database for Enterprise provides data consistency for users
•  Data is accessed by components through a data manager layer

• Supports a variety of third-party relational database management systems (RDBMS)
