This topic provides an overview of the process of mapping target system files to the Optimizer on a test system using Target Level Emulation.
The following graphic indicates the flow of how target system optimizer environmental cost parameters are mapped to test system structures that, in turn, cause the test system query optimizer to generate request plans that are based on the environmental cost parameters and data demographics of the emulated production system.
The flow for dynamic AMP statistical samples is essentially identical after making the necessary changes to the node labels in the diagram.
