Oracle E-Business Suite Release 11i runs Oracle9i Application Server 1.0.2.2.2 as its internal application tier. Oracle E-Business Suite Release 12 runs Oracle Application Server 10g. Both EBS 11i and 12 can optionally be integrated with externally-deployed Fusion Middleware 11g components such as Oracle Internet Directory, Discoverer, Portal, Oracle Business Intelligence Enterprise Edition, and others.
Oracle Fusion Middleware 11g is Oracle's latest suite of related and interoperable application tier server products. Some Fusion Middleware products have dependencies on other Fusion Middleware products. As an E-Business Suite DBA or systems administrator, it is essential that you have a good conceptual understanding of Fusion Middleware 11g concepts before jumping into administration or installation tasks.
This information is covered in the Fusion Middleware 11g guides themselves, of course, but it's spread across many different documents. This is the first in a series of articles in which I'll cover the essential concepts that E-Business Suite sysadmins need to know about Oracle WebLogic Server, Webcenter, Oracle Internet Directory, Portal, and Discoverer. These concepts are important for Fusion Middleware architectural design, installation, administration, integration, configuration and troubleshooting.
Key Fusion Middleware 11g Concepts
Oracle WebLogic server (WLS) is the application server for Oracle Fusion Middleware 11g. Most Fusion Middleware components require WLS, with notable exceptions being Oracle Internet Directory (OID) and Oracle Virtual Directory (OVD). Oracle Internet Directory and Oracle Virtual Directory can be configured with or without a WebLogic domain.
Fusion Middleware components are divided into two types:
- Java Components: Deployed as one or more Java applications and a set of resources. Examples: Oracle SOA Suite, Oracle WebCenter.
- System Components: A manageable process that is not deployed as a Java application. System components are managed by Oracle Process Manager and Notification (OPMN). Examples: Oracle Internet Directory, Oracle Virtual Directory, Oracle HTTP Server, Discoverer, Forms & Reports.
