In computing, the Oracle Application Server 10g (the "g" stands for grid), consists of an integrated, standards-based software platform. It forms part of Oracle Corporation's Fusion Middleware technology stack. The heart of Oracle Application Server consists of Oracle HTTP Server (based on Apache HTTP Server) and OC4J (OracleAS Containers for J2EE) which deploys J2EE-based applications. The latest version of OC4J offers full compatibility with the J2EE 1.4 specifications.

Oracle Application Server became the first platform designed for grid computing as well as with full life-cycle support for service-oriented architecture (SOA).[citation needed]

The current release of Oracle Application Server, 10g R3, does not feature a metadata repository tier, relying instead on metadata repositories provided in previous releases.

Following Oracle's acquisition of BEA Systems, their stated aim is that “key features [will be] integrated with WebLogic Server with seamless migration”.[1] The first stage of integration is expected in October, 2008 with a more complete release in May, 2009.



Oracle Corporation subdivides some of its products into varying "editions" — apparently to facilitate marketing and license-tracking.

Available Oracle AS editions include:-

  • Enterprise Edition
  • Standard Edition
  • Standard Edition One
  • Java Edition



Oracle Corporation refers to its implementation of the Java2 Enterprise Edition specification J2EE as Oracle Containers for J2EE and abbreviates the concept as OC4J. OC4J, originally based on the IronFlare Orion Application Server, has developed solely under Oracle's control since Oracle Corporation acquired the source code.

OC4J includes the following servers:


Oracle Application Server can utilize an "Oracle AS Infrastructure Database" — an Oracle database instance supporting the Oracle AS Metadata Repository and/or Oracle Identity Management.[2]
