Scaling is the process of increasing or decreasing the capacity of the system by changing the number of processes available to service requests from Oracle Business Intelligence clients. Scaling out a system provides additional capacity, while scaling in a system reduces capacity.
Scaling is also a critical part of configuring a deployment for high availability.
Scaling the Oracle Business Intelligence environment applies principally to resource-intensive system processes and Java components. When you deploy more processes, Oracle Business Intelligence can handle more requests while staying responsive to requests.
Vertical scaling:
Vertical scaling involves adding more Oracle Business Intelligence components to the same computer, to make increased use of the hardware resources on that computer. For example, Oracle Business Intelligence can be vertically scaled by increasing the number of system components servicing requests on a given computer and results in increased use of the hardware resources on a given computer.
Horizontal scaling
Horizontal scaling involves adding more computers to the environment. For example, Oracle Business Intelligence is horizontally scaled by distributing the processing of requests across multiple computers.
The three system components that support both horizontal and vertical scale-out are Oracle BI Presentation Services, the Oracle BI Server, and the JavaHost.
