212 CHAPTER 10 MONITORING Figure 10-2. Excel graph of logical reads and physical reads produced using the time- series data in the table
CHAPTER 10 MONITORING 213 Monitoring Performance Be sure to monitor the performance of important queries. The view records execution statistics such as executions, CPU time, elapsed time, logical reads, and physical reads for each SQL statement cached in the library cache—it is therefore a source of workload information as well as performance information. Snapshots of the information in the view are available in the table (in the case of STATSPACK) and in the view (in the case of AWR). The SQL statement in Listing 10-10 retrieves the average execution times of each of two SQL queries of choice in successive time periods; the query can easily be modified to include additional queries that are critical to application performance. Notice the use of the analytic function to interpolate missing values. Listing 10-10. SQL Query to List the Average Elapsed Times for Two SQL Queries of Choice
