Exception Reporting with Enterprise Manager

Hypothesis Testing – The senior Oracle DBA can easily run correlation analysis to detect correlations between important performance metrics.  Queries can be developed to show the correlation between buffer busy waits and DML per second for specific tables, averaged over long periods of time.

Comparing a Single Value to a System-wide Value – For example, issue an alert when the physical writes for any data files exceeds 25% of total physical writes.

The next section will be an examination of how an Oracle professional can obtain valuable information from the AWR.

Exception Reporting with the AWR

At the highest level, exception reporting involved adding a where clause to a query to eliminate any values that fall beneath the pre-defined threshold.  Below is a simple script called report_sysstat.sql which displays a time-series exception report for any statistic in dba_hist_sysstat.  Note that the script accepts the statistics number and the value threshold for the exception report.
