Thank you. ------------------------------- Figure 5-3. This code snippet details the collection of values for service time classification based on v$sysstat. Figure 5-4. This code snippet takes the raw CPU v$sysstat values as gathered in Figure 5-3 and produces the service time classification breakdown. Figures 5-3 and 5-4 report that on this Oracle system, over a 120-second interval, the Oracle instance consumed 10.01 seconds of CPU. This is what Oracle consumed, what Oracle's CPU requirements were, and if the same workload continues, what Oracle will consume over the next 120-second interval.
