Selection processing
When the Data Optimizer component is enabled, it determines whether to provide performance benefits by taking control during every open request.
After Data Optimizer identifies the data set and open requester, it determines whether any matching selection criteria exist. If Data Optimizer finds no matching selection criteria, optimization is bypassed. If Data Optimizer finds matching criteria, Data Optimizer continues processing by evaluating the performance options associated with the selection criteria. The first option evaluated is the ACTION option. The ACTION option instructs Data Optimizer to intercept the open request for optimization (INCLUDE) or to bypass the request (EXCLUDE).
Selection criteria and their corresponding performance options can be specified to Data Optimizer in the following ways:
