Oracle Application Server

The Oracle Application Server 10g (the "g" stands for grid) (short Oracle AS), 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 Java EE) which deploys Java EE-based applications. The latest version of OC4J offers full compatibility with the Java EE 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).

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: “key features [will be] integrated with WebLogic Server with seamless migration”.[1]

History

Oracle Corporation marketed its first application server using the name Oracle Web Server (OWS).[2] A subsequent repackaging resulted in the Oracle Application Server (OAS).[3] A later product, superseding OAS, became the iAS (Internet Application Server).[4]

Editions

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

Components

OC4J

Oracle Corporation refers to its implementation of the Java EE specification 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:

Implementation

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.[5]

OPMN - the Oracle Process Management and Notification server - monitors components of the Oracle Application Server.[6]

Operation

The opmnctl command starts, stops and monitors Oracle AS components.[7]

gollark: Oh, and you can index strings so `("abcd")[4]` returns `"d"`.
gollark: I also made it so you can add and subtract functions.
gollark: PotatOS also uses `debug` to provide its `viewsource` command.
gollark: I also let you add and subtract strings.
gollark: But if you do it the other way round it might break because this doesn't *quite* obey the normal rules of arithmetic.
