You can add new WebFOCUS applications to a shared WebFOCUS instance or set up a new WebFOCUS instance to host applications. In either case, usage patterns may be unknown, but we need to estimate resource utilization using some ROT extrapolation method. You can:

• Extrapolate from captured statistics for an existing query workload profile that may be similar to the new workload.
• Conduct benchmarks for the existing query workload profile that may be similar to the new workload.
• Create a new custom query workload profile and conduct benchmarks to simulate anticipated usage.

Using an Existing Query Workload Profile

The extrapolation method is based on another query workload profile in the company. We have seen customers adopt this approach in proofs of concept, investing in hardware, software, and people resources to get accurate sizing with representative data and usage patterns. It is essential to build a margin of error into the sizing methodology.
