Monitoring Performance During Testing

Because this meeting and the previously discussed Setting Up a Successful Test System are closely related, they may be discussed together to save time and provide greater clarity. The DBA and developers need to have an understanding of what information is required to effectively monitor the performance of the Oracle application throughout the entire testing process. The DBA can offer to show developers how to use the various toolsets provided by Oracle (Oracle Enterprise Manager, SQL Trace, explain plan, BSTAT/ESTAT , autotrace, Oracle traces, V$ tables and Statspack) so that developers can play an active role in performance measurement.  Suggested discussion topics are as follows:

  • Names of all SQL Loader control cards and batch scripts
     

  • Performance measurement goals and expectations
     

  • Determine the test load volume (data volume, concurrent users) required to accurately predict production performance
     

  • Comparison of test system load to estimated production load
     

  • Oracle performance measurement tools.  Suggested tools include:

    • Explain
       

  • SQL*Plus autotrace
