Average Active Sessions - A simple solution to complex performance data
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.
