Presentation Title
Average Active Sessions: A Simple Solution to Complex Performance Data
Abstract
Average Active Sessions, the golden mean of performance metrics, is a simple, powerful and elegant way of displaying the multidimensional data found in Active Session History (ASH). Between the dense approximate samples of ASH and the broad accurate snapshots of Statspack, we find a simple metric that can easily determine database health. In this presentation, find out how to determine Average Active Sessions from Statspack, AWR or ASH and find out how to use the metric with OEM or by hand by mining ASH data.
