What is a Application Server?

• Application Server
• An application server is a server program in a
  computer in a distributed network that provides
  the business logic for an application program.
• Oracle Application Server
• Oracle Application Server is a completely
  standards-based application server that provides
  a comprehensive and fully integrated platform for
  running Web sites and J2EE Applications.

• There are basically three tiers
• Client Tier
• Application Server Tier
• Database Tier

Client Tier

• It contains the web browsers for end users
• From the client computer, a user can connect to
  the middle tier to access the self-service tools
  for publishing information, build applications,
  deploy content management, and administer portal
  environment.

Database Tier

• The Database Tier consists of several components
  that help
• authenticate users, store access control
  information, and pass on the
• Required content to the user based on the
  privileges the user has.
• The Database tier contains
• Application Server Control Console
• Oracle Internet Directory
• Oracle Application Server Single Sign-On (SSO)
• Oracle Application Server Metadata Repository

10
Database Tier

• The Application Server also contains a special
  instance called the
• Infrastructure that uses a database to store
  metadata.
• This database is more correctly in the
  application server tier since it does not provide
  persistent storage for the application.

11
Types of Editions

• Standard Edition This is appropriate for Web
  sites that process a small number of transactions
  with minimal need for application support.

  support that includes Oracle Portal-to-Go if you
  need to deliver content to wireless devices.
