- Se agregó que se puedan configurar en el config.properties los siguientes parametros: - setInitialPoolSize = 3 - setMinPoolSize = 2 - setMaxPoolSize = 5 - Se agregaron en duro a RDConnector los siguientes parametros: - setMaxIdleTime <-- Tiempo máximo de inactividad de la conexión. - setMaxConnectionAge <-- Tiempo de vida máximo de una conexión. - setCheckoutTimeout <-- Tiempo máximo de espera por una conexión.
