10g 

Application Server 10g components reside at each of these layers:

 

10gFunctional Architecture of Application Server 10g:

 

10g

  • The web tier is managed by the Oracle HTTP Server, which is based on the Apache web server.
  • Oracle Portal : are used to define web page components.
  • Oracle Reports : defines content specifications
  • Oracle Single Sign-On (SSO) controls security for the app server layer.
  • Database using any of the available J2EE database connection methods.
  • Client Tier:

    10g

  • Oracle Discoverer -- This component allows for the easy end-user query implementation.

    10g

  • Oracle Forms Server -- This component is used to format, deploy, and render end-user presentation pages, based on data in an Oracle Database.

  • Oracle Personalization -- This component provides personalized URL referrer tracking and a facility for creating customized web pages, depending upon the user and his or her web page viewing history. The web page history is kept in Oracle Databases.

    10gThe customized HTML personalization is based on data from three sources:

    10g

  • Oracle Wireless -- This component allows for communications between Application Server 10g and wireless devices such as PDAs and cell phones. Wireless dynamically reformats information to display correctly on the limited screens of most wireless devices.

  • Oracle Reports Server -- This component allows for the fast deployment of reports, documents, and spreadsheets, all using data from the Oracle Database.
  • Single Sign-On (SSO) -- This is a complete authentication system for identifying users, managing roles and web services, as well as functionality for Java and portal security.

    10g

  • Oracle Internet Directory (OID) -- This LDAP-compliant directory service provides centralized storage of information about users, applications, and resources in your enterprise.

  • Metadata repository (Infrastructure) -- This critical component is sometimes referred to as the Infrastructure. It stores Application Server 10g metadata and allows for a common management interface between multiple instances of Application Server 10g and its other components.

  • Oracle Management Server (OMS) -- This component of the Enterprise Manager console allows for managing the Application Server 10g instances, databases, and other applications.

  • Oracle Application Server TopLink -- This component provides object persistence for Java information. TopLink contains the mapping interfaces to translate the Java structures into relational tables, thereby making Java persistent across independent executions.

  • These components are partitioned within the Application Server 10g app server layer, allowing administrators flexibility in the creation of multiple Application Server 10g instances.
