HammerDB Variable or Step Workloads are an advanced testing feature that enables you to automatically vary the load on the database over a period of time. When taking this approach you would not focus on the test result but instead monitor the databases ability to cope with the variation in demand and transaction response times.

.” Basic understanding In order to understand segmentation fault, it is necessary to understand memory management methods for processes. When a program leaves the memory, space becomes available; however, the OS may or may not be able to allocate vacant memory space to another program or process as it has some issues.
