Abstract

In order to reveal the dependency relationships between configuration
parameters and performance measures of database connection pool technology,
the GeomGeomcc discrete-time queuing model with multi-server is built according
to its working principles. Using the embedded Markov chain method, the analysis
of the model is completed and the mathematical expressions of system performance
measures are derived, such as request blocking probability, average number of
connections, system utilization, and system throughput etc. Finally, numerical
examples are given to discuss the impact of these four performance measures
on request arrival rate and maxConn the maximum number of connections intuitively.
The analysis results of this study provide theoretical bases for the parameter
configuration of database connection pool.
