OBIEE 11g Setting Up Shared Files and Directories

Setting up shared files and directories is an important step before thinking about vertical or horizontal scaling. The following components has to be places on the shared storage to take advantage of the scaling.

Oracle BI Repository File (RPD File)
Oracle BU Presentation Catalog
Global Cache

Before we start create the directories for the above three components on the shared storage.

Now in Fusion Middleware , go to the coreapplication of Business Intelligence Instance.
Under Deployment Tab , select Repository Tab
Update the Shared Location for both the Catalog and Repository

Now Update the Global Cache location also mention the cache size under the Performance Tab.

Restart the services to take effect.

We have completed the pre-requisite for adding processes to the scaled out system. Next we will see on activating the components on the second instance.

Horizontal Scaling OBIEE 11g

Horizontal scaling in OBIEE means adding more Business Intelligence Components to a separate computer to make use of the hardware resources.


On the new server copy the setup files for OBIEE and then run the Installer. Select Enterprise Install and then select Scale Out BI System option.

Here fill out the hostname where the primary setup is installed and the port number for the weblogic is listening.

The installer gives and option to place the Domain Home , Applications Home and Instance Home.

Select the option to auto allocate the ports or to give a preference for the port.

Review the summary and confirm the Installation.

After the confirmation the installer copies the relevant files to the directories.

Here you can see the Scaling Out Domain process take place.

Now the scale out process is completed successfully.

Installation Summary

Instance 2 is added and you can see it under the fusion middle-ware console.

In the next post we will see how to add the components.
