Construction of User Concurrent Profile Based on Usage Logs

With the wide application of software systems based on Service-Oriented Architecture (SOA), the reliability of such software has received more and more attention. Software reliability testing and evaluation is an important means to improve reliability of SOA systems, the first step of which is the construction of an operational profile. However, using traditional operational profile is difficult to describe the characteristics of user concurrency and the real usage scenarios of SOA systems. Moreover, it is also difficult to ensure the accuracy of operational probabilities because of the subjectivity of expert experience in determining the probability of an operation. In this paper, a construction method of user concurrent profile based on usage logs is proposed. In the user concurrent profile, the characteristics of user concurrency in SOA software systems is embodied; besides, the accuracy of usage probability can be ensured due to the data from usage logs.
