Oracle testing to destruction

Oracle Database Tips by Donald BurlesonMarch 12, 2015

Question:  What is testing to destruction and how does it apply to Oracle technology?

Answer:  When testing the performance of Oracle databases, it is a best practice to use a tool to hammer the database until it "breaks".  By breaking, we mean the point at which the database throughout is seriously impaired on "hung", a point at which the database will not allow new transactions.  See these notes on Oracle benchmark testing

The most popular Oracle stress testing tool is Oracle's Real Application Testing (RAT) and the Quest Benchmark factory.

Testing to destruction is a well-known technique and the findings are critical because the DBA will then know, a-priori, the critical bottleneck for the database, and the transaction rate at which performance degradation occurs.

When testing to destruction it is important to extract a representative real-world workload and avoid faked "test cases".  See these notes on finding the proper workload for testing your database to destruction.

For a full methodology for testing to destruction, see the book Oracle Tuning: The Definitive Reference.
