Figure 9-59. Graphical representation of detail data on I/O difference between two ADDM timelines in a comparison
report
With this detailed data, you can quickly assess that there was a 75 percent jump in memory usage and a
significant difference in data-file single-block read latency between the two timelines used in the comparison.
As with other reports in the EM12c interface, there is an option to save or e-mail an HTML report for later review
or to retain for historical reference.
Summary
As the need for automating and optimizing the database and its environment increases, the importance of the
Enterprise Manager 12c performance console will increase in demand as well. Top Activity will slowly migrate to ASH
Analytics, with its robust, transparent, and effective reporting. The opportunities to gather data from a simple and
efficient graphical interface and provide effective optimization recommendations and monitoring provide the clear
direction for enterprise-level database control.
