Thank you. ------------------------------- This chapter is different. Sure, the previous chapters have focused on Oracle performance diagnosis, but in this chapter, I pull everything together, filling in any missing pieces and introducing some additional diagnosis topics. This chapter will also complete the conceptual framework of performance diagnosis coverage, paving the way for the next three chapters on Oracle internals. When reading this chapter, keep in mind everything that you've read about so far: Oracle's instrumentation, how to trace operating system processes, Oracle response-time analysis (ORTA), OraPub's 3-circle analysis methodology, that spinning on a latch is service time not queue time, and how to gather operating system utilization from v$osstat. If any of these topics seem unfamiliar, I respectfully ask you to turn back to those pages. With the first four chapters as a foundation, we are now ready to begin completing our diagnostic focus.
