Oracle EBS Architecture Overview
March 31, 2023

 

Oracle EBS (Enterprise Business Suite) is a set of integrated applications developed by Oracle Corporation to manage complex business processes. It includes various modules such as financials, supply chain management, customer relationship management, human resources, and more. Oracle EBS is widely used by large and medium-sized businesses around the world. In this blog post, we will provide an overview of the architecture of Oracle EBS.

 

Oracle EBS Architecture Overview:

The architecture of Oracle EBS can be divided into two main components: the database and the application tier. The database tier consists of the Oracle database management system, while the application tier includes the application server and the web server.

 

1) Database Tier:

The database tier is responsible for storing and managing all the data in Oracle EBS. The Oracle database is used to store all the data related to the various modules of Oracle EBS. The database is typically installed on a separate server or a cluster of servers, depending on the size of the organization.

The database tier is further divided into three components: database instance, database schema, and database tablespaces.

 

a. Database Instance:

The database instance is a set of memory structures and background processes that run on the server to manage the database. The database instance includes various memory structures such as the System Global Area (SGA) and the Program Global Area (PGA).

 

b. Database Schema:

The database schema is a logical container that holds all the objects related to a specific module or application within the database. Each module or application within Oracle EBS has its own database schema.

 

c. Database Tablespaces:

The database tablespaces are the physical containers that hold the data files that store the data for the various modules and applications in Oracle EBS. Each tablespace is associated with a specific database schema.

 

2) Application Tier:

The application tier is responsible for running the various applications and services in Oracle EBS. It includes the application server and the web server.

 

a. Application Server:

The application server is responsible for running the various Oracle EBS applications and services. It provides a runtime environment for the Oracle EBS applications and manages the communication between the various components of Oracle EBS.

The application server is typically installed on a separate server or a cluster of servers, depending on the size of the organization. It includes various components such as the Oracle Forms Server, Oracle Reports Server, and Oracle Concurrent Manager.

 

b. Web Server:

The web server is responsible for handling the HTTP requests and responses between the user’s browser and the application server. The web server provides a runtime environment for the Oracle EBS web-based applications.

The web server is typically installed on a separate server or a cluster of servers, depending on the size of the organization. It includes various components such as the Oracle HTTP Server and the Oracle Web Cache.

 

3) Middleware Tier:

In addition to the database tier and the application tier, there is also a middleware tier in Oracle EBS. The middleware tier includes various components such as the Oracle Business Intelligence (BI) server, the Oracle WebLogic server, and the Oracle Identity Management (IDM) server.

 

a. Oracle Business Intelligence (BI) Server:

The Oracle BI Server provides a platform for creating and delivering business intelligence reports and dashboards. It enables organizations to analyze their data and gain insights into their business processes.

 

b. Oracle WebLogic Server:

The Oracle WebLogic Server is a Java EE application server that provides a runtime environment for Java-based applications. It is used in Oracle EBS to run various Java-based applications and services.

 

c. Oracle Identity Management (IDM) Server:

The Oracle IDM Server provides a platform for managing user identities and access to various applications and services in Oracle EBS. It includes various components such as Oracle Access Manager, Oracle Identity Manager, and Oracle Adaptive Access Manager.

 

4) Integration Tier

 In addition to the database tier, the application tier, and the middleware tier, there is also an integration tier in Oracle EBS. The integration tier includes various components such as the Oracle Integration Cloud Service (ICS), Oracle SOA Suite, and Oracle Data Integrator (ODI).

 

a. Oracle Integration Cloud Service (ICS):

The Oracle ICS is a cloud-based platform that provides integration between various applications and services in Oracle EBS. It enables organizations to integrate their on-premises applications with cloud-based applications and services.

 

b. Oracle SOA Suite:

The Oracle SOA Suite provides a platform for designing, deploying, and managing service-oriented architecture (SOA) applications. It enables organizations to integrate their various applications and services using a common set of standards and protocols.

 

c. Oracle Data Integrator (ODI):

The Oracle Data Integrator provides a platform for integrating data between various applications and databases in Oracle EBS. It enables organizations to extract, transform, and load data from various sources into the Oracle EBS database.

 

5) High Availability Architecture:

Oracle EBS also provides a high availability architecture that ensures maximum uptime and minimizes downtime. The high availability architecture includes various components such as Oracle Real Application Clusters (RAC), Oracle Data Guard, and Oracle WebLogic Server clustering.

 

a. Oracle Real Application Clusters (RAC):

The Oracle RAC provides a platform for running Oracle EBS on a cluster of servers. It enables organizations to scale their Oracle EBS environment as their business grows, and it ensures high availability by allowing the database to continue running even if one server in the cluster fails.

 

b. Oracle Data Guard:

The Oracle Data Guard provides a platform for replicating data between two or more Oracle databases. It enables organizations to create a standby database that can be used in the event of a primary database failure.

 

c. Oracle WebLogic Server Clustering:

The Oracle WebLogic Server clustering provides a platform for running Oracle EBS on a cluster of application servers. It enables organizations to scale their Oracle EBS environment as their business grows, and it ensures high availability by allowing the application server to continue running even if one server in the cluster fails.

 

Conclusion:

In conclusion, Oracle EBS is a powerful and complex enterprise application suite that requires a robust architecture to support its various modules and applications. The architecture of Oracle EBS includes the database tier, the application tier, the middleware tier, the integration tier, and the high availability architecture. Each tier includes various components that work together to provide a reliable and scalable platform for managing complex business processes. Understanding the architecture of Oracle EBS is essential for organizations that want to implement and maintain this enterprise application suite successfully.
