Oracle Business Intelligence System 12c Architecture

Oracle Business Intelligence Components

  • Admin Server —  These components include Oracle WebLogic Server Administration Console, Oracle Fusion Middleware Control, and JMX MBeans.
  • Managed Server — These services and applications include BI Publisher and Visual Analyzer.
    An Oracle BI domain contains one or more Managed Servers that are distributed across one or more host computers.
  • Node Manager — Provides process management services for the Administration Server.
  • System Components — Deployed as server processes and provide the core services that enable Oracle Business Intelligence.
  • Other Domain Contents — Includes all the necessary software, configuration files, metadata, WLST commands, security, and connection and database configuration information that are required to run an Oracle Business Intelligence system.

Administration Server and Managed Servers

The Administration server and Managed servers are Java components deployed as one or more Java EE applications and described in the following list:
  • Administration Server — Manages configuration and runtime setting.

    • Fusion Middleware Control — An administrative user interface that is used to manage the BI domain.
    • WebLogic Server Administration Console — An administrative user interface that provides advanced management for WebLogic, JEE components, and security.
  • Managed Server — Manages the following components:
    • Action Service — This component provides the dedicated web services that are required by the Action Framework .
    • Visual Analyzer — This component provides a simple-to-use visual analytical interface.
    • BI Publisher — This component provides an enterprise reporting solution for authoring, managing, and delivering all types of highly formatted documents.
    • Security — This component provides dedicated web services that enable the integration of the Oracle BI Server with the Oracle Fusion Middleware security platform.
    • SOA Web Service — This component provides dedicated web services for objects in the Oracle BI Presentation Catalog, to invoke analyses, agents, and conditions. These services make it easy to invoke Oracle Business Intelligence functionality from Business Process Execution Language (BPEL) processes.
    • Presentation Services — This component is a JEE application that routes HTTP and SOAP requests to Oracle BI Presentation Services.

      System Components

      System components are deployed as non-JEE components, such as processes and services written in C++ and J2SE, and are described in the following list:
    • BI Server (OBIS) — This component provides the query and data access capabilities at the heart of Oracle Business Intelligence and provides services for accessing and managing the enterprise semantic model (stored in a file with an .RPD extension).
    • BI Scheduler (OBISCH) — This component provides extensible scheduling for analyses to be delivered to users at specified times.
    • BI JavaHost (OBIJH) — This component provides component services that enable Oracle BI Presentation Services to support various components such as Java tasks for Oracle BI Scheduler, Oracle BI Publisher, and graph generation. It also enables Oracle BI Server query access to Hyperion Financial Management and Hyperion Planning data sources.
    • Essbase — This component provides support for Essbase.
    • BI Presentation Server (OBIPS) — This component provides the framework and interface for the presentation of business intelligence data to web clients. It maintains an Oracle BI Presentation Catalog service on the file system for the customization of this presentation framework.
    • Cluster Controller (OBICCS) — This component distributes requests to the BI Server, ensuring requests are evenly load-balanced across all BI Server process instances in the BI domain.

  1. The effectiveness of IEEE Project Domains depends very much on the situation in which they are applied. In order to further improve IEEE Final Year Project Domains practices we need to explicitly describe and utilise our knowledge about software domains of software engineering Final Year Project Domains for CSE technologies. This paper suggests a modelling formalism for supporting systematic reuse of software engineering technologies during planning of software projects and improvement programmes in Final Year Projects for CSE.

    Software management seeks for decision support to identify technologies like JavaScript that meet best the goals and characteristics of a software project or improvement programme. JavaScript Training in Chennai Accessible experiences and repositories that effectively guide that technology selection are still lacking.

    Aim of technology domain analysis is to describe the class of context situations (e.g., kinds of JavaScript software projects) in which a software engineering technology JavaScript Training in Chennai can be applied successfully

    The Angular Training covers a wide range of topics including Components, Angular Directives, Angular Services, Pipes, security fundamentals, Routing, and Angular programmability. The new Angular TRaining will lay the foundation you need to specialise in Single Page Application developer. Angular Training
