Abstract

A general model of an e-business system comprising an application server and a database engine is analyzed and evaluated. Incoming jobs may have to wait in an external queue; when admitted for processing, they compete for the available resources. Database accesses are of different types and are subject to time-outs. An efficient approximate solution is provided; its accuracy is evaluated by comparing the model estimates with those obtained from simulations. The effect of several controllable parameters on the performance of the system is examined in a series of numerical and simulation experiments.
