That means if you are moving to new servers or changing hardware / storage during the upgrade then make sure you're running tests on that new hardware or storage. For a test to be valid you need to use an environment that is as close to the target production system you will be moving to. ![]() Look at individual SQL either manually or through tools like SQL Tuning Sets in Oracle Tuning Packįirst let’s put a few rules in place when it comes to testing.Simulated application workload either manually or with tools like LoadRunner, NeoLoad, or a number of web specific tools.What are your options for testing performance changes when moving from Oracle 11g to 19c?
