1. Which are the main 3 Oracle e-business platform components ?

• Oracle Application Server: to help deploy Internet applications

• Oracle Database Server: to store enterprise business data  

• Oracle Developer Suite: to develop Internet applications

2. What is the Oracle Application Server ?

The Oracle Application Server is an Integrated Software Infrastructure for Enterprise Applications used to deploy Internet applications but also to create and manage enterprise portals and mobile devices, to automate business process and to provide real-time business intelligence. 

3. Which are the key components of Oracle Application Server (OAS) ?

• OC4J ( Oracle Application Server Containers for J2EE)

• Oracle HTTP Server

• Oracle Internet Directory

• Oracle AS Web Cache

• Oracle AS Portal

• Oracle AS Wireless

• Oracle Identity Management (in addition to OID, it includes the Oracle SSO and Oracle CA)

• Management, Integration and Security Components (Oracle Application Server Control, Oracle Internet Directory )

• Oracle Business Intelligence (Oracle AS Discoverer)

4. Which are the key components of the OAS Identity Management ?

• Oracle Internet Directory (OID) = single store for all type of user information

• Oracle Delegated Administrative Services (DAS) = manage the OID

• Oracle Directory Integration and Provisioning. Directory Integration refers to the synchronization of the OID with other directories and user repositories. Directory Provisioning refers to the Oracle AS 10g feature that enable the creation and management of users' accounts and privileges for various Oracle components and applications

• OracleAS Single Sign-On (SSO) = provide the transparent logon to all SSO-enabled applications on all application servers in an Oracle AS farm

• OracleAS Certificate Authority (CA) = manage the public-key certificates. 

5. Which are the 2 main components of Oracle Application Server ?

• Oracle AS Infrastructure = supports the functioning of the Oracle AS middle-tier components

• Oracle AS Middle-Tier = all the applications are deployed and run from middle-tier.

6. Which are the Middle-Tier components ?

• Oracle HTTP Server

• Oracle Containers for J2EE (OC4J)

• Oracle AS Portal

• Oracle AS Web Cache
