Introduction to Oracle Fusion Middleware
Oracle Fusion Middleware is a joined intimate of products ranging from application shape in front tools and integration solutions to identity perspective, collaboration, and issue penetration reporting.
Oracle Fusion Middleware
Oracle Fusion Middleware is a buildup of standards-based software products that spans a range of tools and facilities: from Java EE and developer tools, to integration facilities, identity handing out, matter insight, and collaboration. Oracle Fusion Middleware offers unmodified preserve for magnifying, deployment, and supervision.
Oracle Fusion Middleware Components
Oracle Fusion Middleware provides the later components:
Oracle WebLogic Server, an enterprise-ready Java application server that supports the deployment of mission-vital applications in a robust, safe, intensely nearby, and scalable feel. Oracle WebLogic Server is an ideal launch for building applications based approaching help-oriented architecture (SOA).
Oracle SOA Suite, a solid set of sustain infrastructure components, in a apportion support to-oriented architecture, for designing, deploying, and managing composite applications. Oracle SOA Suite enables facilities to be created, managed, and orchestrated into composite applications and matter processes. Composites enable you to easily accumulate fused technology components into one SOA composite application.
Oracle WebCenter Portal, an integrated set of components considering which you can make social applications, enterprise portals, collaborative communities, and composite applications, built on the order of a standards-based, support-oriented architecture.
Oracle WebCenter Content, an integrated suite of products intended for managing content. This enterprise content outlook platform enables you to leverage industry-leading document government, Web content admin, digital asset dispensation, and records dealing out functionality to construct your matter applications. Building a strategic enterprise content processing infrastructure for content and applications helps you to entry costs, easily allocation content across the enterprise, minimize risk, automate expensive, era-intensive, and calendar processes, and consolidate cumulative Web sites onto a single platform.
Oracle HTTP Server, which provides a Web listener for Java EE applications and the framework for hosting static and full of zip pages and applications on the peak of the Web. Based upon the proven technology of the Apache HTTP Server, Oracle HTTP Server includes significant enhancements that help load balancing, administration, and configuration.
Oracle Web Cache, a content-familiar server accelerator, or reverse proxy that improves the doing, scalability, and availability of Web sites that manage upon Oracle Fusion Middleware.
Oracle Identity Management, provides shared infrastructure for all Oracle applications. It then provides facilities and interfaces that advance third-party enterprise applications add details to. These interfaces are useful for application developers who need to incorporate identity direction into their applications.
Oracle Internet Directory, a general-mean encyclopedia promotes that enables hasty retrieval and centralized meting out of information nearly dispersed users and network resources. It combines Lightweight Directory Access Protocol (LDAP) Version 3 moreover than the high accomplish, scalability, robustness, and availability of Oracle Database.
Oracle Virtual Directory, an LDAP report 3 enabled support that provides virtualized subtraction of one or more enterprise data sources into a single calendar view. Oracle Virtual Directory provides the accomplish to join together LDAP-au fait applications into diverse directory environments even if minimizing or eliminating the way to shape either the infrastructure or the applications. It supports a diverse set of clients, such as Web applications and portals, and it can secure directories, databases, and Web facilities.
Oracle Identity Federation, a self-contained federation unlimited that provides the infrastructure that enables identities and their relevant entitlements to be propagated across security domains this applies to domains existing within supervision as nimbly as together in the middle of organizations.
Oracle Access Manager, which provides a full range of Web perimeter security functions that newscaster Web single sign-upon, authentication and credited appreciation, policy administration, and auditing. Single sign-upon (SSO) enables users and groups of users, to admission complex applications after authentication. SSO eliminates union sign-upon requests. Oracle Access Manager is the Oracle Fusion Middleware single sign-upon unmodified.
Oracle Web Services Manager, which provides a mannerism to centrally add to and control policies that warn Web facilities operations, including entry plan (authentication and authorization), obedient messaging, Message Transmission Optimization Mechanism (MTOM), WS-Addressing, and Web services meting out. Policies can be attached to compound Web services, requiring no modification to the existing Web services.
Oracle Platform Security, which provides enterprise product loan teams, systems integrators, and independent software vendors (ISVs) gone a standards-based, portable, integrated, enterprise-grade security framework for Java Standard Edition (Java SE) and Java Enterprise Edition (Java EE) applications.
Oracle Portal, a Web-based tool for building and deploying e-matter portals. It provides a fixed, light setting for accessing and interacting behind enterprise software services and auspices resources. A portal page makes data from merged sources accessible from a single location.
Oracle Fusion Middleware Concepts
There are two types of components Oracle Fusion Middleware:
A Java component is the Oracle Fusion Middleware component that deployed as one or more Java EE applications and a set of resources. Java components are deployed to the Oracle WebLogic Server domain as part of the domain template.
Examples of Java components are the Oracle SOA Suite, Oracle Web Center Portal, and Oracle Web Center Content components.
A system component, which is an easy to use the process that is not deployed as a Java application. Instead, the system component is managed by the Oracle Process Manager and Notification (OPMN). The system components are:
- Oracle HTTP Server
- Oracle Web Cache
- Oracle Internet Directory
- Oracle Virtual Directory
- Oracle Forms Services
- Oracle Reports
- Oracle Business Intelligence Discoverer
- Oracle Business Intelligence
Java components and system components are peers.
After you install and configure Oracle Fusion Middleware, your Oracle Fusion Middleware feel contains the once:
An Oracle WebLogic Server domain, that contains one Administration Server and one or more Managed Servers. The Administration Server contains Oracle WebLogic Server Administration Console and Fusion Middleware Control. The Managed Servers contains components, such as Oracle WebCenter Portal and Oracle SOA Suite.
If your vibes include system components, one or more Oracle instances. The database that is used as a metadata repository, if the components installed requires one. For example, Oracle SOA Suite requires one metadata repository.
Oracle Fusion Middleware Environment
Your environment in addition to includes a Middleware domicile, which consists of the Oracle WebLogic Server residence, and, optionally, an Oracle Common dwelling and one or more Oracle homes.
Oracle WebLogic Server Domain
An Oracle WebLogic Server administration domain is a logically joined charity of Java components. A domain includes a special WebLogic Server instance called the Administration Server, which is the central mitigation from which you configure and control all resources in the domain. Usually, you configure a domain to adjoin adjunct WebLogic Server instances called Managed Servers. You deploy Java components, such as Web applications, EJBs, and Web services, and subsidiary resources, to the Managed Servers and use the Administration Server for configuration and dispensation purposes lonely.
Managed Servers in the domain can be grouped together into the cluster.
The manual structure of a domain is to push away the manual structure of the WebLogic Server dwelling. It can reside anywhere; it compulsion not be within the Middleware quarters manual. The peak-level manual of a domain is referred to as the domain ablaze.
A domain is the peer of an Oracle instance. Both contain specific configurations uncovered of their Oracle homes.
Oracle WebLogic Server Domain
In the previous topics describe entities in the domain:
- Administration Server
- Managed Servers and Managed Server Clusters
- Node Manager
Administration Server
The Administration Server operates as the central control entity for the configuration of every single one domain. It maintains domain’s configuration documents and distributes changes in the configuration documents to Managed Servers. The Administration Server serves as a central location from which to rule and monitor the complete resources in a domain.
Each domain must have a server instance that acts as Administration Server.
To interact also with the Administration Server, you can use the Oracle WebLogic Server Administration Console, Oracle WebLogic Scripting Tool (WLST), or make your own JMX client. In assistant, you can use Fusion Middleware Control for some tasks.
Both Oracle WebLogic Server Administration Console and Fusion Middleware Control run in the Administration Server. Oracle WebLogic Server Administration Console is the Web-based administration console used to control the resources in an Oracle WebLogic Server domain, including the Administration Server and Managed Servers. Fusion Middleware Control is a Web-based administration console used to run Oracle Fusion Middleware, including components such as Oracle HTTP Server, Oracle SOA Suite, Oracle WebCenter Portal, Oracle Portal, and Oracle Identity Management.
Managed Servers and Managed Server Clusters
Managed Servers host matter applications, application components, Web services, and their associated resources. To optimize proceedings, Managed Servers desist a right of an admission-lonely copy of the domain’s configuration document. When a Managed Server starts, it connects to the domain’s Administration Server to synchronize its configuration document taking into account the document that the Administration Server maintains.
When you make a domain, you make it using a particular domain template. That template supports a particular component or action of components, such as the Oracle SOA Suite. Managed Servers in the domain are created specifically to host particular Oracle Fusion Middleware components.
Oracle Fusion Middleware Java components (such as Oracle SOA Suite, Oracle WebCenter Portal, and some Identity Management components), as skillfully as customer-developed applications, are deployed to Managed Servers in the domain.
If you sore spot to mount uphill added components, such as Oracle WebCenter Portal, to a domain that was created using a template that supports another component, you can extend the domain by creating appendage Managed Servers in the domain, using a domain template for the component that you sensitive to amass.
For production environments that require increased application take movement, throughput, or high availability, you can configure two or more Managed Servers to do its stuff as a cluster. A cluster is a buildup of quantity WebLogic Server instances paperwork simultaneously and energetic together to find the money for increased scalability and reliability. In a cluster, most resources and services are deployed identically to each Managed Server (as contrary to a single Managed Server), enabling failover and load balancing. A single domain can contain fused Oracle WebLogic Server clusters, as skillfully as fused Managed Servers that are not configured as clusters. The key difference along surrounded by clustered and nonclustered Managed Servers is to hold for failover and load balancing. These features are easy to get to on your own in a cluster of Managed Servers.
Node Manager
Node Manager is a Java service that runs as a cut off process from Oracle WebLogic Server and allows you to take steps common operations for a Managed Server, regardless of its location taking into account be impatient very roughly to its Administration Server. While use of Node Manager is optional, it provides valuable ministers to if your Oracle WebLogic Server feel hosts applications later high-availability requirements.
If you rule Node Manager upon a computer that hosts Managed Servers, you can begin and decline the Managed Servers remotely using the Administration Console, Fusion Middleware Control, or the command pedigree. Node Manager can furthermore automatically restart a Managed Server after an unexpected failure.
Oracle Instance
An Oracle instance contains one or more system components like Oracle Web Cache, Oracle HTTP Server, or Oracle Internet Directory. The system components in an Oracle instance must reside upon the same computer. An Oracle instance directory contains updatable files, such as configuration files, log files, and drama files.
An Oracle instance is the peer of an Oracle WebLogic Server domain. Both contain specific configurations outdoor of their Oracle homes.
The manual structure of an Oracle instance is disaffected the calendar structure of the Oracle habitat. It can reside anywhere; its dependence not be within the Middleware residence reference book.
Middleware Home
A Middleware habitat is a container for the Oracle WebLogic Server dwelling, and, optionally, one Oracle Common domicile and one or more Oracle homes.
A Middleware residence can reside upon a local file system or upon a detached shared disk that is accessible through NFS.
WebLogic Server Home
A WebLogic Server burning contains installed files necessary to host a WebLogic Server. The WebLogic Server house directory is a peer of Oracle on fire directories and resides within the calendar structure of the Middleware blazing.
Oracle Home and the Oracle Common Home
An Oracle ablaze contains installed files vital to host a specific component or software suite. For example, the SOA Oracle house contains a directory that contains binary and library files for Oracle SOA Suite.
An Oracle home resides within the encyclopedia structure of the Middleware perch. Each Oracle home can be connected gone complex Oracle instances or Oracle WebLogic Server domains. There can be multiple Oracle homes within each Middleware ablaze.
The Oracle Common stop contains the binary and library files required for Fusion Middleware Control and Java Required Files (JRF). There can be lonely one Oracle Common house within each Middleware land.
Oracle Metadata Services Repository
The Oracle Metadata Repository contains metadata for Oracle Fusion Middleware components, such as Oracle BPEL Process Manager, Oracle B2B, and Oracle Portal. It can then contain metadata approximately the configuration of Oracle Fusion Middleware and metadata for your applications.
A metadata repository can be database-based or file-based. If it is database-based, you can make it in an existing database using the Repository Creation Utility (RCU).
Oracle Fusion Middleware supports multiple repository types. A repository type represents a specific schema or set of schemas that partner a specific Oracle Fusion Middleware component (for example, Oracle SOA Suite or Oracle Internet Directory.)
A particular type of repository, the Oracle Metadata Services (MDS) repository, contains metadata for most Oracle Fusion Middleware components, such as Oracle B2B, and for certain types of applications.
