Test procedure

Read a list of steps that were performed for each test.

1. IPL z/VM system
2. Reconfigure z/VM number of active processors and amount of memory
3. Start the combined workload set (see Combined workload set), that is, all levels and all components of all workloads, within respective virtual systems
4. After 5 minutes, start z/VM monitoring
5. After 50 minutes, stop z/VM monitoring
6. After 5 minutes, terminate workloads
7. Wait until all workloads have terminated
8. Collect performance data

During each test, various Linux® performance data and application related performance data was collected. Performance data from the z/VM monitor was collected during the central 50 minutes of each test execution, thus skipping peak loads occurring particularly during workload start-up. After the 60 minute execution phase, all workloads were terminated, but allowed additional time to complete eventually still running activities. Particularly the Database BI workload is characterized by long running transactions that could run for more than 20 minutes.
