How to to achieve a parallel processing with Cognos 10 and Oracle?
thank you.

Could you explain what your question means? What do you consider parallel? Do you mean getting Cognos processing to happen at the same time as Oracle processing? Do you mean Oracle splitting a single database request across multiple CPUs/servers? Do you mean multiple Cognos reports being processed at the same time, or split between multiple servers?

I just maybe should have asked only about Cognos 10 Parallel processing options, meaning that if there are 100 users running reports at the same time how do we ensure good performance. With the failover server capabilities, administrative settings or there is another way, maybe third party tools??
Thank you ,

Cognos 10 has inbuilt load balancing facilities. You can define how many report services are active on each server, and how many connections are available for each report service. The maximum concurrency for running reports is the number of report services multiplied by the number of connections, and requests will be load balanced across these.

See the Admin and Security guide for details (Chapter 7 - Server Administration):

Thank you very much for your respond! I will review the administrative guide. Is any third party hardware/software can be helpful to ensure parallel processing with Cognos10?

You could deploy an external router to load balance between servers, then switch off the load balancing in the dispatcher(s) if you wish. It might introduce a single point of failure if the router dies, though.
