Title
Stochastic study of real-time transactions success ratio
Abstract
The well-known and accepted criterion for measuring real-time database systems (RTDBSs) performances is to maximize the transactions success ratio. In this paper, we focus on a stochastic study of firm real-time transactions, i.e, transactions which are aborted and discarded as soon as they have missed their deadlines. The results we obtained is the reasonable approximation of this ratio behavior by a probabilistic distribution with defined parameters. To achieve this objective and due to the lack of real data, we have designed a simulator based on components including probabilistic characteristics: a transactions generator and a conflicts generator. The latter is based on data conflicts level. After testing two kinds of concurrency control protocols, a pessimistic and an optimistic one, simulation results have helped us to determine load conditions where a kind of protocol is better than the other.
