Server - Clustered Server
OS Name: LINUX
OS Version: 4AS-X86_64
OS Vendor: Red hat
Physical location: AM-USA-OH-CIN-45249-8700GOV
No of CPUs & No Of Cores: 4 & 8 (Each CPU have 2 cores)
Memory: 7.786426544
Disk space: 32G
Application connecting with 10g DB as backend.




SOLUTION


Please keep in mind that, number of users logged into the system is not the concurrency we are sizing for but rather one should focus on the actual users processing /querying. While there is an exception to every rule, you will rarely see concurrency go above 20% unless its specific to certain business processes for instance Financial Management during a financial close period.

There are several benchmarks conducted on OBIEE 10g easily covering a total user base of 35,000 requirement.

One benchmark supporting over 280,000 named users with a concurrency of 10% at 28,000 concurrent!

For OBIEE 11g, You can also refer to the official capacity guide:

and performance tuning guide:

These are general rule of thumb/guidelines. It is very difficult to suggest capacity planning recommendations without analysis of the expected usage which differs from project to project and customer to customer. Therefore please refer to Oracle Advanced Consulting Services, or your implementing partner, via your Account Director, it is a billable service.
