Oracle has released the OBIEE 11g product, and you have to get used to the concept that OBIEE is now deeply integrated with Oracle Fusion Middleware(OFM). You have to understand a little bit of OFM for understanding OBIEE 11g.
Repository creation utility (RCU)
RCU will be used to create basic repository for Oracle fusion middle ware installation. OBIEE, as part of the fusion middle ware family, also require the support of this repository created by RCU . You have to use RCU to connect to Oracle database and create FMW-related schema before you could install OBIEE 11g.
Part of OBIEE is J2EE application deployed in Weblogic
As the well know fact that Oracle Weblogic(WLS) has become Oracle s de factor application server. For OBIEE 11g, Oracle has also rewritten and deployed part of OBIEE 11g into Weblogic server now. which means that these component is conform with the standard J2EE technology, you could manage and monitor these component using the standard weblogic tools or fusion middle control whichc is the de factor management tools for all of Oracle s middle ware family, you could also use weblogic s mature clustering technology to deploy cluster for these OBIEE java components.
Just login into fusion middle ware control using the following URL
Part of OBIEE 11g change less and managed by Oracle OPMN
Although part of OBIEE 11g is deployed into weblogic, but there re still components that run as standalone just as the previous OBIEE version. I guess that some day Oracle might also relocate them into weblogic server in the future. But It is still outside there and is managed by OPMN with this version, OPMN is another old tools of Oracle for managing standalone process.
The big picture of OBIEE 11g
And here s an image that explain the architecture of Oracle OBIEE 11g
The upper part of the image shows J2EE part of OBIEE 11g, which includes BI Publisher, RTD, Oracle BI for Office and traditional component of Weblogic stack.
The lower part of the image is core of the OBIEE traditional stack which include BI Server, BI Presentation Service and BI Javahost etc. But you have to use OPMN to manage these component now.
Please note that there s a Presentation Service plugin inside weblogic server, and It will redirect all the OBIEE request to the backend Presentation Service. which might still act as before!
