Test Modes

You an tailor tests for different testing needs through a set of modes and test options. These modes and options determine how the tests are run on the system. You have the option of running the tests in three different modes:

  • Online Stress Test Mode

  • System Exerciser Test Mode

  • Component Stress Test Mode

Online Stress Test Mode

Use this mode for testing if you want to simultaneously run other applications in addition to Oracle VTS software on the system. The goal of this mode is to validate the hardware without having significant impact on other applications running on the system. In this mode, the tests would not stress the system, and to provide coverage they might have to run for longer periods of time. If there are any latent faults in the system hardware, the tests in this level try to stimulate those faults before the application is impacted by the fault. When the test stimulates the fault, the OS detects the fault and takes appropriate action.

The test characteristics in this mode are as follows:

  • Nonintrusive – The tests running in this mode do not intrude on the applications that are running on the system. Nonintrusive mode does not change any system configuration that can have an effect on the applications.

  • Data Safe – The tests running in this mode do not cause any kind of data corruption.

  • Test Time – The time of completion for these tests could vary from milliseconds to days. There is no restriction on the amount of time.

  • Resource Usage – The resource usage is designed so that the test does not have any distinguishable effect on the applications that are running on the system. The goal is to use as few resources as possible for a given instance of time.

System Exerciser Test Mode

This mode provides system exercising capability. It tests the system with all its components. All tests are run in parallel. In this mode, no other application except Oracle VTS software should be running on the system. The characteristics of the tests in this mode are as follows:

  • Intrusive – The tests can be intrusive in nature. No other application should run on the system while these tests are running.

  • Data Safe – The tests are data safe by default.

  • Resource Usage – The tests are aware that there could be other tests running. Accordingly, the tests would then allocate and lock resources.

Component Stress Test Mode

This mode performs targeted testing of system components and modules. In this mode, the test puts the maximum stress on the component or module under test. The tests are not run simultaneously with other tests: all tests are run sequentially. No other user application can be running on the system. The characteristics of the tests in this mode are as follows:

  • Intrusive – The tests can be intrusive in nature. The tests might need specific system configuration settings to run efficiently.

  • Data Safe – The tests are data safe by default. The tests assume that the complete system resources are at their disposal and can use resources according to its needs.
