Locate it by searching for "firefighting." 8 When the Statspack and AWR reports base CPU conumption on the v$sys_time_model view, they incorrectly include only server process CPU consumption (DB CPU) in the Top 5 Timed Event report, and do not include any background process CPU consumption (background cpu time). Notice the DB CPU time shown in Figure 9-15 matches the CPU Time statistic shown in Figure 9-14. 9 This response-time formula, called an open-form formula, cannot be solved with algebra. I had two engineers verify this and also referenced Wolfram's Alpha Solver (http://www.wolframalpha.com).
