Workload and Initial Analysis Period
The Workload Analysis Period (Figure 11) specifies the amount of workload sampling that Optimizer should maintain for sample analysis. The minimum is one hour and the maximum is three weeks. The default is one week.
The Initial Period (Figure 11) specifies the minimum amount of workload sampling that Optimizer should complete before analyzing the samples for the first time. This parameter exists in a case where you do not want to wait until the entire workload period has elapsed before Optimizer commences its analysis and swap activity. The minimum is one hour and the maximum is the workload analysis period, which is the default.
